PROCEDURE l REVISION ISSUE NUMBER DATE PAGE TEXAS UTILITIES GENERATING CO. l CPSES CP-Q P-11.12 16 jg( 2 3198 2 of 8 2.2 SCOPE The scope of work shall include those items tha t are designated as WMS, on the flow diagrams, as follows:

1. Ins talla tion ins pection of all Non-A94E WMS piping
2. Hydrostatic Pre-test and testing verification of all Non-ASME WMS piping 3.0 PROCEDURE 3.1 FINAL INSTALLATION INSPECTION i

3.1. .' Visual Inspection of Welds All welds on piping shall be visually inspected in accordance

.dth Reference 1-B.

3.1.2 Base Metal Defects j

Base metal defects shall be repo rted in accondance with Reference 1-C.

3.1.3 Erection Tolerance l

The inspector shall verify that the piping is ins talled within the following erection tolerances:

a. " Gradient - 3/16 inch per foot aximum (this applies to horizontal lines deviating from level Deviation from plumbness of vertical lines onl y.

horizontal departures from design centerline and of horizontal lines will be controlled by the two-inch tolerance on location)."

b. Slope - minimum as designated on drming.
c. Constraints
1) A minimum 2 inch clearance shall be mintained, including insulation, with respect to other piping when one or bo th lines have an operating taperature of 200* F or greater. All other lines,

. may be ins talled wi th a minimum of one-inch clearance, including insulation, with respect to other piping.

2) For clearance of pipe (with an operating temperature of 200 F or greater) from hangers, walls, ceiling, i

handrails, etc., other than pipe to pipe, a minimum 1 of one inch shall be maintained, including pipe insulation, however on a case by case basis it might be necessary to notch insulation to establish clearance which will require engineering approval .

All other lines may be installed with a clearance only for insulation. However, on a case by case j basi s, j ' it might be necessary to notch the

, insulation to establish clearance, which will I

require Engineering approval.

d. Span - span between pipe suppo rts shall not exceed

}. maximum span specified on Attachment 1.

NOTE:

This inspection will be - doceented on an j.

Inspection Report. Attachment 2. - I i

1 j Prior to cepletion of this inspection the inspector shall, e attach As-Built Tags (Attachment 3) to the line. These tags l i shall be place; at strategic locations along the line to i prevent oversight by other plant personnel.- Prior to per-formance of any w rt on a tagged line or its components  :

{ QC shall be notified.

3.1.4 QC will verify that inspections per Reference 1-0 and 1-E 1 have been completed and indicate on the Inspection Report,

HYOROSTATIC TESTING

! 3.2.1 QC Doceent Review

! Prior to hydro, QC shall review existing documentation i to verify that all welds within the hydro boundary have been visually inspected and accepted. This shall ir.clude any attachment wel ds, and all areas of welded repair. If

! acceptable, QC documentation accountability shall be signed

off on the Hydro / Pneumatic Test Record, Figure 6.91-1 of Reference 1-F, by inspector's initial and date on the QE Protest Concurrence block. All other documentation j associated with the Hydro-Test package shall be completed and transmitted in accordance with Reference 1-F.  ;

.! NOTE:

l Inspection per paragraph 3.1.3 need not be completed prior to hydro.

3.2.2 OC Pretest Inspection Prior to commencement of tes ting , the QC Inspector shall verify:

a. All welded joints, attachments, and area of welded repairs which have not been previously tested are accessible for inspection.
b. High points of the system are vented.
c. All surfaces are free of arc strikes.

NOTE: The above verifications need not be made sequential ly. Upon acceptable conpletion of the above verifications, and those of the Test Engineer, pressu re testing may proceed in accordance with Reference 1-E.

3.2.3 Hydrostatic Test Pressure and Holding Time The systen or partial system shall be subjected to a hydro-static test pressure as indicated in Reference 1-G. >

l The pressure shall be maintained for 30 minutes and examined for leakage. .

3.2.4 Witnessing of Tests The test shall be inspected by the Test Engineer and QC.

All joints, high stress areas, and exposed accessible pres-surized surfaces shall be inspected. Acceptance criteria shall be as defined in Reference 1-F. l 3.2.5 Acceptance of Tests The QC Inspector shall doctment inspection activities and approval of pressure tests by signing applicable pressure test record fonns and drawings provided by The Test Engineer. The QC Inspector shall review applicable fonns for campleteness and accuracy before signing. Pressu re tests that are not accepted shall not receive a QC signoff until acceptable conditions have been resolved.
