Specific storage instructions are normally provided by all motor manufacturers. Failure to follow these instructions may void the warranty. Tag the turbine from which the rings have been removed. The carbon rings shall be reinstalled just prior to startup. Removal and reinstallation shall be performedby qualified personnel. An insulation resistance-to-ground test shall be made and recorded. This log will show the datesthe of test and theinsulation resistance value.

Oil levels shall be inspected. An inspection shall be made for any evidence of oil leakage. Shafts shallbe rotated and checked for freedom of movement. Removal and indoor storageof premounted instruments and control panels may be required if such devices cannotbe protected from rain, humidity, temperature, or dusty conditions. Explosion-proof enclosures are not necessarily weatherproof enclosures.

Open conduit connections alcan low entrance of moisture. This subject should have been addressed during the procurement or shop inspection stage,but is sometimes overlooked.

If unable to store indoors, motors shall be stored in their operating position ona well-drained hard surface.

Take care that the desiccant does notcontact any wiring, terminals,or electronic parts. Proper warning signs must be installed to prevent injury or electrical shock to personnel.

Other methods may be harmful to the windings. This tabulation represents an overview ofinteracting factors that allows the specifying engineerselect to the most appropriate preservative for a given situation. Indoor and outdoor storage protection is addressed, but lubricants or preservatives used for oil mist systemsare not covered. The severity of indoor storage is a function of such factors as dampness, poor air circulation, widely fluctuating temperatures,or presence of corrosive fumes.

It does not contain water-displacing or fingerprint-suppressingagents. If stored parts are sheltered from direct exposure to sun, rain, and snow, effective outdoor rust protection can be achieved with this product. For partstoo large to dip, application can be made bybrush.

This product forms asoft, thick, waxy coating on application, with the surface coating gradually drying to forma protective film or crust while the underlying material remains soft and plastic.

This is an important characteristic because it affords a self-healing effect. When a minor break occurs, the softer material will slowly flow together and reseal the damagedfilm. The degree of protection obtained in exposed outdoor environments will depend to some extent on the thickness and durability of thebarrier film provided by the rust preventive material.

This product provides the bestprotection for long-term outdoor storage, but must be removedbefore the part is put into service. The preferredapplication method isby spray, although dipping and brush applications are also suitable.

Many of thedesirable attributes of premium preservatives are listed below: Dry to a mildly tacky film that should not collect appreciable amounts ofairborne particulates. Provide freedom from oxidation in indoor and outdoor storage for extended periods of time. Due to their polar nature, remove water from the pores of the metal, replacing the water with therust preventive coating.

In the form of films, have extremely low moisture transmission characteristics, even in contact with water. Have the ability to neutralize acid, making a suitable rust preventive for acidic atmospheres and wherefingerprints may create a corrosive action on metal surface. Are self-healing, if in film form.

If the film is accidentally ruptured, it should heal overthe ruptured area. Even as film, should be readily removed withsolvent or a solvent-emulsion cleaner when desired. Are safe to apply over partially painted or conventional elastomeric parts.

They are usually spared, relatively small in size power , or Section 2-Machinery Foundation 2. The final detail design of the foundation shall be performed under the directiona qualified of engineer considering all possible forces, deflection limitations, 2. Machinery that requires an elevated in2.

Elevated machinery maybe directly supported by structuralsteel proANSI AmericanNationalStandards Institute vided adequate stiffness and strength is provided. The intent of 2. The common foundation is toreduce the possibility of differential settlement between thetwo components. The grout manufacturer should be consulted to determine the maximum and minimum thickness of grout for a particular installation.

Factors such as flowability and heat generation should be takeninto account when the grout thickness is determined. If the analysis predicts a resonance, then the mass ofthe foundation should beincreased if possible to overtune it. Consideration should be given to incorporating the foundations of several individual machines in the same vicinity into one foundation. A large combined mat foundation may provide a more economical foundation than several closely spaced individual foundations. When multiple machines are placed ona single mat foundation, the designer should consider all possible loading arrangements and combinations of the machines to produce the most unfavorable effects on the supporting foundation, including partial foundation loading dueto removal of individual units for maintenance.

Design load combinations may be as specified in AC1 The foundation shall be designed to support the applied service loading without exceeding the allowable bearing capacity of the soil refer to 2. In the absence of known soil design values, a geotechnical engineer may be employed to provide the field explorationand laboratory testing required to evaluate the soil properties supporting the foundation.

The structural engineer should exercise good judgment as to when a geotechnical engineer is needed. Generally, a geotechnical engineer should always be used for soil foundation designfor machine foundations over kilowatts horsepower. When wind or earthquake loading is included in the load conditions, the allowable capacity can be increased by one-third.

Uplift of the foundation shall be avoided. To reduce the potentialfor differential static settlement, thecenter of the mass of a machine foundation should coincidewith the centroid of the soil foundationor pile resistance. The horizontal eccentricity should be limited to 5 percent of the corresponding foundation dimension. In addition to a static structural analysis, a complete block foundation design may requirea dynamic structural analysis including consideration of thesoil interaction, unbalanced dynamicforces,limiting displacements, and all possible modes of vibration.

A block foundation subject to vibrations may require a dynamic analysis to ensure that the provisions of 2. The minimum mass ratios 3: I and 5: Although the3to-S mass ratio has beena good rule of thumb, in certain installations a dynamic analysis of the rectangular concrete foundation maybe necessary to adequately predict its behavior.

Reinforcing should be continuous fromface to face with proper lap splices. The required reinforcing steel necessary to resist the internal forces and moments is relatively small in the majority of block foundations because of their massive size. Therefore, the minimum quantity of steel will likely be controlled by the amount of steel necessary to meet temperature and shrinkage requirements.

Although AC1 does not specifically address the required steel ina block foundation, the requirementof O. In the event thata foundation size greater than 1. It is desirableto have at least 50 percent of the total depth of the foundation embedded in the soilto increase the lateral restraint and the damping ratios for all modes of vibration.

A typical rectangular block foundation detail is shown in Appendix A. The widthof the foundation should beat least 1. This requires that the pump be provided with a machined mounting plate that is grouted tothe foundation. The foundation must be watertight. Drain holes or openings in the foundation are not acceptable. A larger factor of safety may be required depending on the type of soil. The use of passive soil resistance aroundthe perimeter of the foundation to aid in achieving stability must be used with caution.

The designer may decide to neglect the contribution of passive resistance to stability if the possibility exists of soil loss due to excavation or erosion around the foundation after it is constructed.

The removal of soil around the foundation will resultin loss of the passive soil pressurecomponent. Pumps in low-temperature service that require insulation will need greater clearance to accommodate finished insulation dimensions and piping that may be externalto the pump can.

The bottomsurface of the cavity should be at least millimeters 1 foot beneath the bottom of the pump can. Refer to the typical suspended can pump detail in Appendix B. The foundation designfor variable-speed equipment willrequire that the foundation be checked for resonantfrequenciesthrough theentire range of operating speeds.

The mechanical equipment is supported by the large beamsor the slab locatedat the top of the structure. The height should be determined by the minimum number ofstraight runs of processpiping, the required slope of the lube oildrain piping, or other mechanical and maintenancerequirements.

The effects of vibration generated by the equipment on the operationof adjacent equipmentor people shouldbe factored into the location of the equipment. In addition to taking measures to isolate the foundation from an adjacent slab or structure in the early stages of the project, it may be possible to locate the equipmentto reduce the transmission of vibrations to the surroundis ings.

The intent of this provision is to call attention to the need for foundation isolation due to vibration generated by the machinery.

All necessary precautions should be taken in the design to protect thesafety of personneldirectly exposed to the construction or working in the vicinity of construction.

One of the best times to address the effects that construction may have on the existing facility and personnel in the area is during the initial design stages. Roper location of the foundation may reduce the construction difficulties associated with protectingpersonnel and maintainingexisting production.

In anaggressiveenvironment, consider the use of protective coatings, polymer concrete, or additional concrete cover to protect the reinforcing steel.

Mounting plates shall be of sufficient strength and rigidity to transfer the applied forces to the foundation. The transfer of forces by means of grout chemical adhesion of the baseplate to the foundation shall not be considered in the design.

The anchor bolt embedment shall be adequate to resist the torque values specified inthe grouting section of thispractice or the forces applied by the equipmentor required by applicable codes. Appendix B. In areas exposed to corrosive chemical vapors or liquids, the anchor bolt should be fabricated from a material resistant to chemical attackor provided with a proper chem2. The anchor bolt material selected for use, whether it is the material specified in 2.

This information is not only required forfabrication but may be helpful in future modifications to the foundation. It may be necessary to fabricate the anchor bolts from a material that will be capable of resisting the attack of an aggressive environment.

Not only isthis necessary to prevent the reduction of the anchor bolt net section, but it will also facilitate the future removal of the equipment for maintenance. The innerdiNote: The above information should be clearly marked on the drawing in ameter ofthe sleeve should beat least twice the diameter of order for itto be readily identified during the final checks before concrete the anchor bolts.

The length of the sleeve shall be the greater placement. Refer to the typical foundation detail in Appendix A to clarify of millimeters 6 inches or sufficient length to permit the location of the finished foundation level. Not only is this information necessary for construction of the founbolts to the concrete foundation. Anchor boltsleeves are required to permit a section of the bolt to be protected from concrete or grout adherence.

This section of the bolt is kept free from the concrete and grout to permit the proper elongation of the anchor bolt during the tightening procedure. The use of anchor bolt sleeves is not primarily intended to permit easy bending of the bolt to aid in equipment alignment, but to allow the elongation to take place. Refer to the anchor bolt details in Appendixes C and D. Placing this information on the drawings will permit its permanent retention with the foundation structural details.

Section 3-Machinery Foundation Installation 3. PIP 3. Proper concretepreplacement and placement procedures are essential to the successful installation of machinery foundations. Anchor bolts and sleeves shall be located to the specified tolerances in all three planes and securely supportedto prevent misalignment during the concrete placement operation.

The anchor bolts shall not be reduced in diameter nor offset to facilitate alignment with the mounting plate. Modification of the mounting plate to facilitate alignment is not permitted unless authorizedby the designated machinery representative. The use of a template to aidin the placement of anchor bolts is rec- 3. The template will assistin accurately placing the anchor bolts. The contractor shall provide the 3.

This will require the soil beneath the foundation tobe examined by a ified to matchthe anchor bolt hole locationin the mounting qualified soil specialist or geotechnical engineer suitable to the equipment plate.

The anchor bolts shall also be examined to verify that they have 3. All necessary procedures shallbe taken to correct any discrepancies or deficiencies before concrete operations shall 3.

Adequate control of the concrete temperature shall be maintainedat the pour point. If a slump greater than millimeters 4 inches is required for proper placement ofconcrete, it may be increased upto millimeters 8 inches using a high-range water-reducing agent. The ability of concrete to reach the specified strength is a function of temperature and moisture retention.

Normal concrete, when properly 28 days afcured, will attain the specified design strength approximately be presumed to have reached the speciter placement. The concrete shall fied compressive design strength when the requirements of AC1 for removal of formwork have been met. If approved by the equipment user, the use of highearly strength concretemay be used to reduce the duration time requiredto reach the desired strengthin situations where curetime is on the critical path.

Refer to AC1 and AC1 for additional information on curing concrete. AC1 , Specificationsfor Structural Concretefiw Buildings,requires that normal concrete be cured preservation of moisture for 7 days after placement. The equipment user or the designated machinery representative reserves the right to subject the concrete foundation constructiontoinspection by anACI-certified inspector or any owner-designatedtesting agency.

In general, the instructions supplied by the grout manufacturer should be carefully followed. The reduction ofaggregatequantity in grout mixtures to improve flow properties is not permitted.

Rapid-flow epoxy grouts shall notbe used unless specifically approved by the user. Typically, rapid-flow grouts are only used for grout pours of less than 40 millimeters 1 inches.

Additional special-purpose machinety requirementsare covered in the appendixes at the end of this chapter. Grout layout drawings shall be completed during engineering design and shall be submitted to the downloadr for review. These drawings shall be included in the design packagefor the machinery foundation. Grouting design drawings or typical data sheets shall provide all necessary information for the installation of equipment on mounting plates.

This information shall include, but not be limited to,the following: Expansion joint location. Elevation to top of mounting plate.

Elevation to top of grout. Grout materials and estimated quantities. Grout pocket location if any. Grout formingdetails that deviate from AppendixF and head-box elevation.

Baseplate grouting and vent holes. Anchor bolt location and projection. Grout pin locations and quantity if used. Shimming and leveling screw requirements. Epoxies typically have over three times the compressivestrength of cementatious grouts and tend to have a longer useful service life.

Epoxy grouts are also available that are resistant to chemical attack. Cementatious grouts are also typically not resistant toacid and chemical attack. The first layer for this type of installation shall be general purpose epoxy grout pouredto a level that is 25 millimeters 1 inch above the bottom of the internal baseplate stiffeners.

The secondlayer shall be a nonshrink cementatious grout poured to a level that is approximately 50 millimeters 2 inches from the top of the baseplate decking. The top layer shall be ageneral purpose epoxy grout and shall be poured to the top of the baseplate. Note that the next layer for this type of installation shall not be poured until the previouslayer is properly cured. Expansion joints should be placed at approximately 1. Polystyrene may also be used.

Ensure that the expansion joint material is compatible withthe grout. The purposeof this section is to provide the foundation designerwith mounting plate design criteria necessary for properinstallation.

All baseplates shall have radiusedcorners appropriate to the baseplate design. Shims and wedges should not be used.

They may also allow moisturepenetration and the resultant corrosion and grout spalling. Vent holes of at least 12millimeters inch insize should be provided at the highest point of and in each bulkhead section of the baseplate. These measuresallow for controlledgrout placement and verification that each section is filled with grout. This allows the mounting platebar shall be provided aroundthe perimeter ofthe mounting to be supportedby the grout, notby the leveling devices.

Cinch minimum imbedment depth beforeinstallation of 2.

Whenthe baseplate is to be grouted, it should be provided with at least one grout holehaving a clear area of at least 0. These holes should be located to permit 2. Much preparationis required before the grout is actually poured. These pregrout preparations can make the difference between a grout job lasting for the life of the machinery,or only a few monthsor years.

This section defines the minimum recommended procedures, practices, and inspections for the installation of grouted equipment mounting plates soleplates and baseplates. The purpose of these instructions is to provide guidelines for the installation of grouted mounting plates. In general, the instructionssupplied by the grout manufacturer should be carefully followed. During the mixing, handling, and installation of grout materials, the following minimum practices must be employed: Additional special-purpose machinery requirements are covered in the appendixesat the end of this chapter.

Goggles or face shields and aprons should be worn by those personnel mixing and pouringthe grout. Protective gloves should be worn by all personnel involved in thegrouting operation.

Dust masksor respirators in accordance with MSDS requirements should beworn by those personnel exposed to the aggregate prior to mixing. Soap and water should be available for periodic hand cleaning, should the needarise. Some epoxy grouts exhibit a very strong exothermic reaction and the possibility of thermal burns exists.

Caution must be exercised in this regard. Concrete mustalso be exposedto a drying-out period to ensure that the capillaries are free of moisture and will provide propergrout bonding. AnchorBoltPreparation 3. This material will prevent water accumulation inthe anchor bolt sleeves and is pliable enough to allow for small anchor bolt movement, if needed. Anchor bolt sleeves are not intended to provide sufficient movement to allow for gross misalignment of anchor bolts to their mounting plate holes.

Lateral movement for alignment purposes should not exceed 6. A chipping hammer with a chisel bit is the preferred tool forthis purpose. For machinery foundations where the grout extends to the edge of the concrete, the corners of the concrete shall be chipped to form a millimeter 2-inch minimum 45degree chamfer.

Grout forms shall be placed so as to allow proper filling of the chamfer area. The purposeof the concrete foundation chamferis to providea shear plane at the grout-to-concrete interface to prevent delamination.

Protectivesheeting suchassheets of clean polyethylene shall be used to cover the prepared surfaces when work is not in progress. Power nailing is not permitted. Wind, sun, rain, and ambient three coats of paste waxapplied to prevent grout adherence.

During hot weather, the foundation and equip3. Grout leaks will not self-seal. Bitumastic or room grout from being exposed todirect sunlight as well as dew, temperature vulcanizable RTV silicone rubber canbe used mist, or rain. In cold weather, a suitable coveringto allow the for this purpose. A convective heating source should be provided so as to raise 3. A minimum of 25 millimeters 1 inch of concrete must be removed in this chipping process down to a depth to permit 25 to 50 millimeters 1 to 2 inches minimum ofclearance between the concrete and the bottom ofthe soleplate.

Scarifyingthe surface with a needle gunor bushing toolor sandblastingto remove laitance from the foundation is unacceptable. All chamfer edges required in the grout should be incorporated intothe forms because epoxy grout cannotbe easily cut or trimmedafter hardening.

All sharp edges are to be broken. Shims and wedges are not to be used. They may also allow moisture penetration and the resultant corrosion and grout spalling.

This allows for controlled grout placement and verification that each sectionis filled with grout. In general, vent holes of approximately 12 millimeters V 2 inch in diameter on centimeter inch centers should be provided.

Note 1: Epoxy primers have a limited life after application. Thegrout manufacturer should be consulted to ensure proper field preparation of the mounting plates for satisfactory bonding of the grout.

For baseplates with interlocking structural members, sandblastingof the bottom of the base is usually not required. Such baseplates rely on the interlock of structural shapes into the grout, as opposed to the bond between the grout and the coating. Liquid waxes and oilare not permitted. Care must be taken to prevent wax from contacting the concrete foundation or metal surfaces that will be in contact withthe grout.

All plugs areto be coated withpaste wax to prevent grout adherence. This allows the baseplateto be supportedby the grout, not by the leveling devices.

These can be removed with a solvent wipe-down. The mounting plate grout surfaces should have been prepared and readyfor installation by the machinery manufacturer;if not, then they must be prepared as follows: Care must be taken to avoid any damageto mounting plate machined top surfaces. Levels should always be checked before beginning the plate leveling process by checking level repeatabilitywhen reversing degrees. Individual soleplate elevations are to be set to a tolerance of Elevation adjustment nuts are not permitted under the baseplate that will be grouted in and become This allows the baseplate a permanent part of the foundation.

Typical Data Sheets for this purpose are shown in AppendixB at the end of this section. To for those installations where the soleplate is bolted to the balance the length of sighting distance, the tilting level is to bottom of the crankcase priorto grouting, alignment mustbe be set near the foundation within a 6-meter foot radius verified and recorded before pouring anygrout.

Of particuof all soleplates. A peg test of the instrument prior to the start lar importance are the following alignmentreadings: Frame level. Crankshaft web deflection ideally this should be zero. As a general rule of thumb, the web deflection should not exceed micrometers per meter 0. OOOl inches per inch 3.

All baseplate level measurements shall be taken on the ties such as scaffolding and laborers , the grouting materials equipment mounting surfaces. Typically this meeting is done for special-purpose equipmentor prior to pouring the grout foundations for a group of similar equipment.

There should be no entrained shall be packed witha soft moldable material such as foam air in the resinhardener mixture. This is to ensure that the anchor bolt sleeves do not fill 3. Anchor bolt threads must also be protected with 3. For small pours, grout can be mixed in a clean wheelbarrow 3. Typically, the elevation to the top of the grout extends half the thickness of the soleplate. Advantages of removingpump and driverare as follows: Baseplates are easily leveled, using the machined mounting pads to check for levelness, without distortionof the baseplates.

Access to grout holes for groutingis improved.

With baseplates that are sloped, leakage from the lowest vent hole is more easily controlled. Grout cleanupof pump and driver is not required. Cleanup of baseplates is easier. This will prevent air entrapment. Do not vibrate the grout as a means of helpingit flow as this tends to separate the aggregate from the resin binder. Limited use of push tools may be employed to help distribute the grout, using long strokes rather than short jabs.

Violent ramming of the grout is not permitted. This aisgood way to check for air pockets and insufficient filling.

Leaks will not self-seal, and if not stopped, will cause voids. All samples are to be labeled andtheir batch placement location noted.

39814140-API-686-Machinery-Installation.pdf - Recommended...

Troweling and brooming may be facilitated by the use of grout solvent. Troweling and broomingshall be carried out ina manner thatprecludes excessive blending of the grout solvent into the surface of thegrout.

This coating shall extend down fromtop theof thefoundation at least 45 centimeters 18 inches. The Table A-1 in Appendix A may be used as a guide if manufacturer informationis not available.

Do not plug any baseplate fill and vent holes 3. Mark the void areas to allow for proper identification when filling. A solid 3. This will ensure that the grout has obtained most ofits strength and hardness. The groutis of sufficient hardness if a sixpenny finishing nail cannot be driven into the grout surface. Correction of level may include removal and regrouting or field machining of the equipment mountingsurfaces.

This canbe done by placing a magnetic-based dial indicator on the soleplate referenced to the concrete foundation and checking for any movement as each anchor bolt is loosened and retightened. Soleplate movement should not exceed 20 micrometers 0. Grout is then pumped a grout gun until the grout emerges from the vent holes. It is therefore extremely important that the grout and vent holes are in communication with each other. An air squeeze bottle may be used to test for communication by blowing air into the grout hole and notingits exit at the vent hole do not use high-pressure air.

Remove all grease fittings when finished. If void areas still exist, repeat the drilling and pumping proceduresas necessary. Foundation anchor bolt threads are undamaged.

In all cases theelongation of the bolt will indicatethe load on the bolt. Determine high end of baseplate. Then start levelingacross pads on high end by adjusting leveling bolts adjacent to the pad that youare leveling. For example, when leveling driver pads A and B in crosswise direction, level at anchor points 1 and 2 see Figure D-1 with level positioned as shown by Figure D Continue leveling until baseplate is levelin crosswise direction at places illustrated by Figures D-2 and D-3 -pads A and B must be level across middles and acrossends, particularly those ends nearest pump.

Useonly base pads for determining level. Never use nozzles or baseplate rails. Level both sides of baseplatein lengthwise directionby adjusting leveling boltsadjacent to pad that you are leveling. For example, when leveling pad A, level at anchor points 1, 3, and5 , Figure D-1, with level positionedas shown by Figure D Continue leveling until both sides of baseplate thatis, pads A,B, and eachside of pump are level in lengthwise direction at places illustratedby D-4 and D Tighten foundation anchor bolts and pump feet hold-down bolts.

As you tighten bolts, position level as illustrated in the four leveling figures and check levelingin both crosswise and lengthwise directions.

A line from the dischargeof a pump, blower, or compressor routed backto the suction system. The recycle line may connect directly into the suction line or may connect into suction vessels or liquid knockout vessels and may include a cooler; also known as bypass line,minimumflow bypass, or kickback line. Special-purpose equipment trains will be defined by the user.

An analysis of the piping system connectedto a machine to determine forces and moments on nozzle connections caused by various loading conditions such as pipe weight, liquid loads, and thermal expansion or contraction. These forces and momentsare compared to vendor-allowable loads or national standards to ensure that nozzle loadings meet guidelines. This analysis includes specificationof pipeanchors, guides, supports, and sometimes spring supports and expansion joints to control strain.

Where large vertical piping displacementsoccur, machinery may sometimes be mounted on spring-supported baseplates to reduce nozzleloading.
