'

  • The Quality Control Inspector (QCI) shall verify that pipe spools to be joined are identified as described in Reference 1-A. Addi tionally, the QCI shall record the Material Requisition number the pipe spool is released on for threaded connections only.

3.2 THREADED CONNECTIONS '

3.2.1 Pipe Wall Thickness The QCI shall verify the pipe wall thickness is as specified 1

on the BRP drawing in addition to the following: (This is performed at the time of threading.) -

a. pipe with a wall thickness less than that of standard weight of ANSI B36.10 steel pipe shall not be threaded, -

regardless of service (See Attachment 1 for standard wall thickness);

.b. threaded pipe connecting to orifice flanges shall have

' a minimum wall thickness of schedule 80.

3.2.2 Thread Compound The QCI shall verify that only Neolube No. 2 is used as a thread compound and is applied as follows:

a. Neolube is limited to threads and shall not protrude onto the unthreaded portion of the pipe;
b. Neolube is applied in an even, uninterrupted coat anti -

allowed to dry prior to thread enama r.t.

3.2.3 Threads CN M Unmh' r A D M A.T h I

3.2.4 Pipe Thread Engagement The QCI shall verify the minimum thread engagement of .

threaded connections as shown in Attachment 2, column L2 ' .

3.2.5 Threaded Connections Requiring Seal Welding The QCI shall verify and visually inspect seal welding in accordance with Reference 1-B in addition to the following:

a. no thread compound is used; -
b. exposed threads are completely covered with weld metal.

3.2.6 Documentation The results of QCI verifications shall be recorded on the Construction Operation Traveler (Reference 1-C), if utilized by Construction. If no traveler is used, QCI verification shall be recorded on Inspection Report, Attachment 3. On l

completion - of all QCI verification, the discipline QC Superintendent shall review the documented results and indicated approval by signing and dating the appropriate

. document. When seal welding is performed the inspection results shall be documented as required by Reference 1-A.

~

Threading QCI verification (see 3.2.1) shall be documented on the Manufacturing Record Sheet (Reference 1-A).

3.3 FLANGE CONNECTIONS 3.3.1 Cleanliness The QCI shall verify flange faces are thorou es o remove rust, scale, dirt, paint, etc. s if]\ ,{

1 3.3.3 Alignment The QCI shall verify flanges are aligned as follows:

a. within 3/64 inch normal and with respect to flange outside diameter; except
b. when pipe is to connect to a flange - on equipment (i.e.. . valves, pumps, etc.), the face of the flange is aligned to the lesser of 25% of the gasket thickness or as described in a. above. -

3.3.4 Bolting The QCI shall verify at least one complete thread is exposed above the nut face.

3.3.5 Documentation The Construction Operation' Traveler shall be used to .

document the QCI verifications described in this section (Reference 1-C).

4.0 . NONCONFORMANCES All nonconfonning conditions will be reported in accordance with Reference 1-D.
