Orientation Record (Attachment 1). Major nozzle locations e.g., inlet / outlet nozzles, shall be used to determine proper equipment eleva tion. For la teral location, verification shall be made by using theoretical column lines. 3.4.2 Leveling of Equipment 3.4.2.1 Leveling of Rotating Equipment Base pla tes shall be checked for levelness in lengthwise and crosswise directio6. High end of the base plate shall . be determined and subsequent leveling shall proceed. For equipment setting requiring grout, a minimum grout space of one inch shall be provided at the point of minimum clearance be tween the equipment bases and the concrete foundation. Leveling shall be achieved by use of the taper wedges, by adding or removing the shims or by adjusting leveling nuts. Base plates shall be shimmed and leveled to three thousandths of an inch per foot using machinists level or optical levels ' on available leveling surfaces. If no leveling surface is furnished, rotating equipment may be leveled to 1/8 inch end-to-end. 3.4.2.2 Leveling of Non-Rotating Equipment
- a. Heat exchangers shall be leveled to 1/4 inch end-to-end, using optical levels from the bottom of the shell. Side to side leveling may be performed using a carpenter's level placed on the base. It shall be shimmed so that the bubble is contained between the two closest lines l on the level.
- b. All equipment excluding rotating equipment and Leat exchangers may be set using a carpenter's level placed on the base or machined surface, as appropriate. The equipment shall be shimmed so that the bubble is contained between the two closest lines on the level.
NOTE: For a and b above, equipment setting requiring grout, a minimum grout space of one inch shall be provided at the point of minimum clearance between the equipment bases and concrete foundation.
; BROWN & ROOT, INC. ISSUE CPSES NUMBER REVISION DATE PAGE JOB 35-1195 4 of 12 QI-QAP-11.1-39 4 yg 3.4.3 Anchoring of Equipment Upon completion of the leveling, the anchor nuts shall be snug tight or shall be torqued per manufacturer's recommendations. Tightening of anchor nut shall be performed in such a way that it does not disturb the leveling of the equipment. Recheck the level of base plate af ter tightening the anchor bolts.
QCI shall verify that anchor bolt threads are not damaged prior to and during the setting of equipment. . Af ter recheck alignment, locking nuts or double nuts shall be installed on all anchor bolts for rotating equipment unless othemise specified by the engineer. Installation of - locking nuts or double nuts shall be documented on the OT. For anchor bolts with locking nut installed, nut as a minimum must be flush with the top of anchor bolt. 3.4.3.1 Themal Expansion Anchored Equipments For equipment that may require a slidir.g end to allow for themal expansion as shown on the vendor design or the engineers's design drawings, nuts on anchor bolts shall be brought to a hand tight condition. Anchor bolt location on sliding end shall be in the center of the slotted hole unless othemise specified by Engineer. Anchor bolts on equipment that requires a siding end shall also have double nuts or locking nuts installed if sufficient bolt projection l j exists. If sufficient anchor bolt length is not available for the installation of the double or locking nut, the threads of the anchor bolt shall be upset or the bolt l staked accordingly. Half nuts shalI be considered adequate for locking or double nut. Providing locking' nut or double nut is not installed, a minimum bolt = projection of one and one-half threads past the top of the anchor bolt nut shall be required to provide adequa te space for upsetting of anchor bolt threads or staking of the anchor bolt. 3.5 ALIGNMENT OF ROTATING EQUIPMENT l Pump and motor are joined directly by rigid flange coupling I or by a flexible coupling. A flexible coupling is not a universal joint and must be aligned with the same care and accuracy as a rigid coupling. Misalignment will cause l noise, shaft vibration, hot bearings, and rapid wear of j bearings, bushings, wearing rings and seal (or packing) and

To assure satisfactory working of pump-motor units, it is necessary that units are aligned accurately within the manuf actu rer's recommended tolerances. Equipment alignment shall be accomplished as per the instructions on the OT. 3.5.1 Preliminary Alienment 3.5.1.1 Prior to starting any alignment, the following shall be checked, as applicable. All machine feet must be checked to assure that they are I a. finnly supported by the base. If one of the supports is shorter than the . others (a condition called a "sof t foot"), it must be shimmed to the same height as others. _
- b. Assure that shaft run-out of the equipment is within the limits prescribed on Rotating Equipment Alignment Card on the OT.
- c. Only one of the machines, usually the driver (motor),
is adjusted to align with the other (i.e., pump). Therefore the driver must be set slightly low so that , it can be raised into position with shims.
- d. The end gap between driver (motor) and driven unit (pump) shaf ts is maintained per manufacturer's recommendation,
- e. The indicator brackets are of rigid construction and finnly attached to the couplings to minimize sag. The indicator bracket sag must be known and this sag nust be taken into consideration in aligning the equipment. QCI shall docunent the bracket sag on Rotating Equipment Alignment Record, Attachment 2. Indicator bracket sag shall be subtracted from the bottom 0.D. reading only. -
- f. Prior to rotating tne units, the presence of lubricating oil / grease shall be checked in pump / motor bearing housing.
3.5.1.2 Preliminary alignment shall be completed prior to grouting. The most commonly used tools are straight edges and feeler gauges. Calipers or inside micrameters can be used instead of the feeler gauges if the end gap is large. The acceptance criteria for this alignment shall be as fc11c1
S BROWN & ROOT, INC. ISSUE CPSES - NUMBER REVISION DATE PAGE QI-QAP-11.1-39 4 6 of 12 JUN 111984
- a. Straight Edges - should have solid fla t contact on both coupling halves, or
- b. Bubble Level - the bubble should be wi thin the two closest lines on the level indicator, or
- c. Feeler Gauges - the coupling gap shall be set with a 10.020 of an inch tolerance - face to face.
3.5.2 Grouting Equipment shall be grouted (if required) after it is set I to proper orientation / location / elevation / leveled, securely fastened to foundation and preliminary alignment has been completed and accepted. QCI shall sign and date the - Equipment Lev el / Lo ca ti o n/ El ev a t i o n/0 r i e nta ti o n Record (Attachment 1) after verifying that the equipment is at predetermined position as indicated on design drawing. QCI shall verify that minimum grout space of one inch is provided at the points of minimum clearance between the concrete foundation and foundation base plates. 3.5.3 Fine Alignment i Fine alignment shall be completed after the base plates are grouted and bolted down but prior to piping / duct connections are made. For typical dial indicator set-up for shaf t alignment see Rotating Equipment Alignment Record Sheet (Attachment 2). The total indicator reading shall be within the manufacturcr's recommendation and as reflected ! on Rotating Equipment Alignment Record Sheet. The maximun l amount of shims added shall be up to 1/8 inch between the i pump and/or motor casing and their respective supports or bases. Use of additional shl.ns i.e. in excess.of 1/8" shall be allowed wi_th Owner's approval . Owner's approval shal l I be documented on the OT or a memo from the Owner attached to the OT. Fine alignrent shall be made by one of the following methods,
- a. Face and rim method:
The mounting of dial indicators and sequence of operation is as detailed on Attachment 2. If recommended by the manufacturer, the bracket shall be mounted on the other coupling and alignment readings verified to assu re that alignment is satisfactory.
BROWN & ROOT, INC. ISSUE CPSES NUMBER REVISION DATE PAGE J08 35-1195 QI-QAP-11.1-39 4 7 f 12 JUN 111981
- b. Reverse alignment method:
When reverse alignment method is initiated on the OT, the OT shall have Reverse Alignment Verification Graph (Attachment 3) attached to it along wi th Rotating Equipment . Alignment Record (Attachment 2). The alignment reading shall be taken from pump to motor and motor to pump coupling and be plotted on the Reverse Alignment Verification Graph. The shims shall be adjusted under the motor feet. The final alignment reading shall be wi thih the alignment tolerance - recommended by the manufacturer and as indicated on OT. The dial indicator's "M&TE Number" and "Due Date of Calibration" shall.be recorded on the Reverse Alignment Verification Graph. - 3.5.4 Pennanent Connections After satisfactory completion of fine alignment of equipment, suction and discharge piping connection shall be made in accordance with applicable installation procedure. Pemanent hangers and supports shall be installed and adjusted to the cold position as indicated on the drawings prior to pipe connection beirig made to rotating equipment. When permanent supports cannot be installed, temporary hard supports may be used with written approval from Engineering. l l Fit-up of pipe to equipment shal1 be accomplished by adjusting l the pipe and supports to provide accurate alignment without I stressing the pipe or equipment. The rotating equipment coupling alignment is to be monitored l during the pipe fit-up and weld out (or bolt up) to ensure that the equipment is not being moved and that the coupling alignment is maintained with the desired limits. _ _, If temporary supports were used as pennitted above, and the i suction and discharge was connected to the equipment, special care shall be exercised when removing the temporary supports and installing the pennanent supports. 3.5.5 Recheck Alignment The recheck alignment shall be perfo nned during or l after the connection of the suction and discharge piping or ducting. The coupling alignment shall be monitored to l y _

If piping or ducting causes the misalignment of the equipment, the coupling misalignment shall nonnally be corrected by readjustment of pipe or ducting. The alignment may be corrected by equipment readjus tment (i.e., pump) with Owner's concurrence. After equipment adjustment, the coupling alignment must meet the manufacturer's recommended tolerance. Recheck alignment may be perfonned as discussed in Paragraph 3.6.3 (a) or (b), as recommended by the manufacturer. Note: Alignment performed after the recheck alignment for monitoring purposes only (i.e., for verifying the effect of unbolting and rebolting of spool after -
initial installation) and do not require any adjustment of equipment, may be documented on Rotating Equipment Alignment Record Sheet. - 3.5.5.1 Effect of Piping Connection on the Equipment During the inspection of the recheck alignment, QCI shall wi tness the bol ting of flange connections on the inlet and discharge nozzles. The stress or load released or applied during this operation will be monitored by the use of dial indicators set on the coupling rim in the vertical and horizontal positions or on the equipment nozzle as directed by Engineering. The total indicator runout shall not exceed the amount recommended by the manufacturer for equipment alignment. QCI shall document these readings on the OT and/or on Rotating Equipment Alignment Record Sheet. l 3.5.6 Doweling Drive units shall be doweled to the drive unit base as recommended by the manufacturer or as directed,by the Owner. The size and location of the dowel pins shall be as described on the OT. 4.0 TROUBLE SHOOTING Af ter completion of recheck alignment and during ini tial operation, if any problem is encountered with the equipment operation, the work shall be perfonned in accordance with the instructions on the OT.
