2.0 GENERAL l 2.1 PURPOSE AND SCOPE 0

This instruction delineates the criteria and inspection requirements to be used when performing fabrication and installation of ASME Class 1, 2, and 3 snubber assemblies (Reference 1-A and 1-B).

2.2 SNUBBER 701IE01VA"0\'0\ Y These are supplied by both ITT Grinnell and NPSI in seven sizes, 1/4 through 100. All seven sizes are available in two configurations. One configuration is the fixed length type (ITT Grinnell - figure 306, NPSI - SMF). In this type, the bracket is attached directly to the snubber housing (see Attachments 1 and 2). The other configuration is the variable length type (ITT Grinnell figure 307, NPSI - SMA).

The variable length snubber is supplied with a transition kit which consists of an adapter that mounts directly to the snubber, a pipe extension piece with an internally threaded end coupling welded on one end, and an eyerod which threads into the end coupling. (See Attachments 1 and 2).

-1195 2 7 f 42 QI-QAP-11.1-28A APR 281983 5.4 MODIFICATION OF NPSI REAR BRACKETS When the snubber interferes with the rear bracket, the rear brackets for 35 and 100 snubbers may be modified in accordance with Attachment 11. Modification may be by thermal means or machining. If thermal cutting is used, the cut edges shall be smoothened by machining. In either case, the pin shall be removed prior to the modification.

5.5 MODIFICATION OF FORWARD BRACKETS FOR SNUBBER SIZES 35 AND 100 Modification of forward brackets for 35 and 100 snubbers shall be done in accordance with Attachment 12.

5.6 MODIFICATION OF SNUBBER TRANSITION KITS (GENERAL)

Shortening or lengthening of snubber transition kits to a length that will render snubber pin to pin dimensions outside maximum lengths specified in Attachment 22 must be approved in writing by Engineering on a case by case basis.

NOTE 1: If the threaded portion of the eyerod bottoms out in the transition kit before the desired

• adjustment is acheived, the eyerod may be shortened to achieve the necessary adjus tment. However, enough threads shall remain to allow full thread engagement in the coupling nut.

NOTE 2: For identification of snubber parts / hardware discussed in this section, see Attachments 1 and 2.

a. For both NPSI and ITT Grinnell snubbers the required transition kit length shall be detemined by measuring the pin to pin (C-C) distance in the field. Then subtract the actual cold setting (AC dimension shown on the des ign drawing) from the existing pin to pin dimension. The difference between these two dimensiont is the transition kit length required to maintain th?

proper cold setting.

The C-C dimension provided in the Bill of Material or in the sketch are provided for material take-off purposes only. The maximum C-C dimensions are provided in Attachment 22 for the different size s nubbers .

Deviation from these dimensions is not permitted unless authorized by a design change.

BROWN & ROOT, INC. ISSUE CPSES NUMBER REVISION DATE PAGE

~11 QI-QAP-11.1-28A 2 APR 281983 8 of 42

b. Deviation of more than 11/8" from the specified cold setting (AC dimension shown on the design drawing) is not pennitted unless authorized by a design change,

c. If adjustment of an ITT-Fig. 307 snubber is required for installation, the threaded eye rod in the transition kit has an adjustment capability of 3 1/2".

For NPSI-SMA s nubbers , this adjus tment capacity is 21 3/4". Any further adjustment necessary may be made only by modification of the transition kits.

d. In order to lengthen the transition kit, remove the end coupling by grinding or cutting. Snubber sizes 1/4 through 10 have a transition kit mounting plate which must also be removed.

e. If the mounting plate is damaged during removal, a new one shall be fabricated from SA-36 or SA 515 Grade 65 steel,

f. Replace the pipe portion of the transition kit with a size and grade of pipe selected in accordance with Attachment 13 and cut to length necessary to acheive the required pin to pin dimension.

9 The length of ITT Fig. 306 snubbers can be adjusted only by the use of shim plates placed behind the rear bracket. NPSI-SMF snubbers can be adjus ted either by placing shim plates behind the rear bracket, or by trimming the forward bracket in accordance with Paragraph 4.2.1.

h. In those cases where interference problems exist when installing snubbers, they may be mounted 180*

(end to end) from the configuration shown on the.

design drawing.

5.6.1 Mounting of_ Forward Bracket or Transition Kit into SnubberBody For snubber sizes 35 & 100, screw the transition kit or forward bracket into the internal threads at the base of the snubber until it bottoms against the internal dust cover or until the threads meet the minimum thread engageinent.

For NPSI foiward bracket or transition kit, minimum thread engagement is as detailed in Attachment 12. For ITT supplied forward bracket and transition kit, the existing thread length provided on the part is adequate. However, trimming of the thread length for ITT parts is prohibited, unless authorized by Engineering. The thread engagement operation should be completed by hand. If more force is required, remove part T

BROWN & ROOT, INC. ISSUE CPSES NUMBER REVISION DATE PAGE JOB 35-1195 9 of 42 QI-QAP-11.1-28A 2 APR 281983 and -clean all internal and external threads. If after cleaning, thightening is difficult, a strap wrench or other non-ma rring tool may be used to assist in the tightening operation. However, the parts shall not be forced. After fully engaging the threads or bottoming, the forward bracket may be unscrewed up to a maxmimum of 1/2 turn to achieve correct orientation of the lugs and pins on each end of the snubber per the pipe support sketch.

CAUTION: Do not unscrew more than 1/2 turn.

5.7 INSPECTION CRITERIA '

The following are inspection requirements when inspecting snubbers :

~

a. Verify that flat was hers are installed between the spherical bearing and each clamp' half. The spacers may not fit when assembling the , rear bracket due to the tolerances. At this time, one or more of the spacers may be deleted.

NOTE 1: Spherical bearing misalignment shall not exceed 15' with respect to the snubber assembly at any position of the total stroke.

NOTE 2: Minor adjustments of the pipe clamp may be required to facilitate snubber installation.

b. The clamp pin should be long enough to accomodate cotter pins on either side.

c. Verify pinned connections have fully opened cotter pins or split snap rings installed.

d. Verify spherical bearings are tightly staked in the attachment ends.

5.7.1 Snubber Alignment Due to Field Conditions Due to field condi tions , it may be necessary to adjust the alignment between the snubber end cap and the mounting hardware (rear bracket or pipe clamp) in order to allow a full 5* misalignment tolerance. All

5.7.1.1 Snubber Sizes 1/4 through 10 - See Attachment 14.

1. Remove attachments from the snubber.

2. Place the snubber in a vertical position on a table setting on the snubber housing.

3. While keeping a slight downward hand pressure, on the top to avoid linear movement, use retaining ring pliers to free retaining ring.

4. While maintaining a slight downward hand pressure, slowly turn end cap by hand only to desired rotational position. Do not use wrench or other mechanical means.

5. While maintaining hand pressure, replace retaining ring.

Expand and contract arrestor slowly through full stroke to determine that repositioning has not damaged internal components .

5.7.1.2 Snubber sizes 35 & 100 - See Attachment 15.

1. With the assembly cradled in a bench, remove the three indicator tube mounting screws. Extend the snubber sufficiently to expose the telescoping tube.

a. Never interchange NPSI and ITT Grinnel parts or hardware.

However, except for the feedwater and mainsteam systems, I and snubber sizes 35 and 100, NPSI and Grinell snubber bodies may be interchanged.

b. It is extremely important that the clamp halves are parallel (see illustration on Attachment 17).

Excessive gap at the upper end of the clamp can allow enough space for the spherical bearing to be dislodged l from the eye rod end. l i

c. At no time shall installed snubbers be used as steps or hand-hol ds .

NOTE: Pipe clamp assembly information - see Attachment 17-21.

d. When arc welding, do not attach ground to snubber or any part of the snubber which will cause arcing currcat t psc through snubbers.

e. Do not sandblast snubbers. Snubbers are pre-finished with accepMble corrosion protection.

ASME Class 1, 2 and 3 and subsequently used in the fabrication of Class 1, 2 and 3 supports.

2.0 INSTRUCTION 2.1 SALVAGING Never interchange NPSI and ITT Grinnel parts or hardware.

However except for the feedwater and mainsteam systems, and snubber sizes 35 and 100, NPSI and Grinnel snubber bodies may be interchanged.

Snubbers and associated hardware may be used on component supports other than those for which they are designated, provided requirements of this instruction are met.

When an item is salvaged for use on a support other than the one for which it was designated, the original support mark and serial number; or mark, MIC or heat number; or mark and heat code shall remain distinguishable on the item.

If the vendor fabricated snubber assembly with ASME Code plates are salvaged and used on supports other than those for which they are designated, the Code plate (s) shall remain attached to the item if one or more welds remain. When all vendor welds are removed, the code plate (s) shall be removed, provided the original support number is transferred to the vendor part. Authorization to remove name plates which are shown on the drawing shall be provided by Engineering on the appropriate design change. Construction shall transmit the a QC will subsequently

_ Code plate transmit the (s) to QC Code plateby(s)3-part memo.

to the Owner.

For B&R fabricated snubber assemblies that are to be salvaged which contain welds and these welds are to be salvaged, Welding Engineering is responsible for providing the documentation (WDC, WFML,. etc.) necessary for QC to accept these welds. This documentation shall become part of the new snubber data package.

ISSUE CPSES NUMBER REVISION DATE PAGE QI-QAP-11.1-28A 2 APR 281983 23 of 42 ATTACHMENT 6 (Continued) 2.2 LOCATION OF SALVAGED SUPPORTS When B&R fabricated and vendor supplied snubber assemblies, either Code stamped or not, are designated for salvage and returned to the warehouse, these assemblies shall be reinspected by receiving QC in accordance with Paragraph 2.3.

B&R fabricated and vendor supplied snubber assemblies that are to be salvaged need not be returned to the warehouse.

ASME Field QCI shall reinspect the salvaged items in accordance with Paragraph 2.4.

2.3 SALVAGED MATERIAL RELEASED FROM WAREHOUSE Upon receipt of Material Requisitions (MR) from the warehouse for salvaged snubber assemblies / parts , the Receiving Inspector shall verify the following:

~

a. The MR identifies the intended use of the material or pa rts ,

b. The MR identifies the original mark or support number from which it was salvaged if the part being salvaged is a Code stamped part.

c. All material, parts, or assemblies are identified by a unique mark or assembly number traceable to the original support identification for vendor supplied Code stamped parts.

d. B&R fabricated snubber assemblies parts or materials and B&R bulk exhibit a heat number which is traceable to an available material certification.

e. All vendor supplied snubber parts , materials, or assembli es are traceable to an available material certification.

2.0 INSTRUCTION 2.1 SPHERICAL BEARING STAKING INSPECTION Spherical bearings that are loose in the eye rod or snubber ends or have become dislodged require restaking prior to installation. Prior to commencement of the s taking operation, cons truction personnel will notify QC. This notification gives the QC Inspector an opportunity to monitor the s taking operation. Upon completion of the staking operation, the QC Inspector shal.1 inspect the eye rod (or snubber end) to verify the following:

a. The eye rod hole is not deformed;

b. The bearing race is centered in the eye rod hole and should be staked approximately 1/16" from the edge.

However, this dimension is not critical as long as the bearing meets the conditions in C, D and E below.

c. The bearing shall be free from rust, dirt and other foreign material;

d. The bearing gimbal moves freely in its race,

e. The race is secured within the eye rod.

2.2 DOCUMENTATION l

Spherical res taking shall be documented on an l bearing (See Table 1 of this Attachment) and on Inspection Report '

the MWDC. The support mark number shall be recorded in the

" Identification No." block.

Completed documentation shall be reviewed and transmitted to j Quality Engineering Systems for filing in respective hanger i document package. l 2.3 NONCONFORMANCES All nonconfonning conditions shall be reported in accordance with Reference 1-D.  !
