FEB 021983 7 f 41 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 minimum or maximum lengths specified in Attachment 13 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 adjustment.
- However, enough threads shall remain to allow full thread engagement in the coupling nut.
NOTE 2:
Fur ' 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 dall be detemined by measuring the pin to pin (f C) distance in the field.
Then subtract the ac W Otk setting (AC dimension shown on the design didW Jr,)
om the existing pin to pin dimension. The utfferute between these two dimensions is the transition kit length required to maintain the proper. cold setting.

FEB 021983 8 of 41 b.
Measurements shall be taken to ensure that the snubber can be installed with the proper "C-C" dimension while maintaining the cold setting specified on the design drawing. Deviation of more than 21/8" from the specified cold setting (AC diz:nsion shown on the design drawing) is not pennitted unless prior approval is obtained in writing from Engineering.
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 snubbers, this adjustment capacity is il 3/4".
Any further adjustment necessary may be made only by modification of the transition kits on snubber sizes 1/4 to 10.
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 3 and cut to length necessary to acheive l
the required pin to pin dimension.
g.
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 adjusted 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.

FEB 021983 9 f 41 5.7 INSPECTION CRITERIA The following are inspection requirements when inspecting snubbers:
a.
Verify special flat washers are installed between the spherical bearing and each clamp half.
NOTE 1:
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 provided the resulting gap is less than the thickness of one spacer.
NOTE 2:
Spherical bearing misaligned shall not exceed 15' with respect to the snubber assembly at any position of the total stroke.
NOTE 3:
Minor adjustments of the pipe clamp may be required to facilitate snubber installation.
b.
Verify pinned connections have fully opened cotter pins or split snap rings installed.
c.
Verify spherical bearings are tightly staked in the attachment ends.
5.7.1 Snubber Alignment Due to Field Conditions Due to field conditi ons, 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 15*
misalignment tolerance.
All adjustments of this type shall be performed in accordance with the following instructions and witnessed by the QCI.
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.

FEB 021983 10 of 41 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.
2.
While the telescoping tube is restrained from rotating, loosen the left hand threaded nut (ring).
(Nut has been torqued to 1501 20 ft. lbs.) Rotate the end cap to the desired position.
CAUTION: Under no circumstances shall the end cap be rotated more than one complete turn from the bottomed out position.
3.
Re-torque the left hand threaded nut to 150 20 ft. Ibs.
4.
Replace the indicator tube and screws.
5.
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 (for NPSI snubbers) or makes the full thread engagement (for ITT snubbers).
This operation should be completed by hand.
If more force is required, remove part and clean all internal and external threads.
If after cleaning, tightening is difficult, a strap wrench or other non-marring tool may Le used to assist in the tightening operation.
However, the parts shall not be forced.
After bottoming or full thread engagement, as applicable, the forward bracket may be unscrewed up to a maximum 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.

GENERAL REQUIREMENTS a.
Never interchange NPSI and ITT Grinnel parts. However, except for the feedwater and mainsteam systems, 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 from the eye rod end.
c.
At no time shall installed snubbers be used as steps or hand-holds.
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 current to pass through snubbers, e.
Do not sandblast snubbers.
Snubbers are pre-finished with acceptable corrosion protection.
)
f.
If sandblasting is to be performed on adjacent parts f
such as unfinished pipe or structure, snubber and bearings on attaching parts must be masked for p,rotection.

2 and 3 and subsequently used in the fabrication of Class 1, 2 and 3 supports.
2.0 INSTRUCTION 2.1 SALVAGING 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 QC will subsequently Code plate (s) to QC by(a 3-part memo. transmit the Code plate s) to the Owne For B&R fabricated snubber assemblies that are to be salvaged which contain welds and these welds are to be l
salvaged, Welding Engineering is responsible for providing the documentation (WDC, WFML, etc.) necessary for QC to accept these welds.

FEB 021983 34 of 41 ATTACHMENT 16 1.0 GENERAL 1.1 PURPOSE AND SCOPE This attachment provides the inspector with the inspection criteria to be used when inspecting the restaking of spherical bearings.
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 staking operation, construction personnel will notify QC.
This notification gives the QC Inspector an opportunity to moni tor the staking operation.
Upon completion of the staking operation, the QC Inspector shall 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 Spherical bearing restaking shall be documented on an Inspection Report (See Table 1 of this Attachment) and on the MWDC.
The support mark number shall be recorded in the
" Identification No." block.
Completed documentation shall be reviewed and transmitted to Quality Engineering Systems for filing in respective hanger document package.
2.3 NONCONFORMANCES All nonconforming conditions shall be reported in accordance with Reference 1-D.
