05/14/84 3 of 27 The PS may make a weld in the Pipe Fab Shop (PFS) which was designated a field weld on the fabrication drawing and the weld shall be treated as a shop weld. The spool number will not be changed, e.g., if field weld number 3 is between spools D and E, D and E will still be considered separate spools.

Piping, valves, etc., supplied with equipment packages shall be installed per this procedure. Where vendor requirements differ from those given in this procedure, the more stringent requirements shall apply.

Piping for instrumentation bridles shall be welde'd and fabricated in accordance with FSI drawings issued by the Instrument and Control Engineering Department. Since instrument bridles do not utilize line numbers, the entire assembly will be considered as one spool piece and all welds will be denoted as field welds as shown on the drawings.

The Instrumentation Superintendent '(IS) is responsible fo r assuring conformance with the requirements of this appendix.

The use of teflon tape is prohibited for persanent pipe connections unless explictly allowed by approved design doc ume nt s.

The boundaries of a component to which piping is attached shall be at the limit of reinforcement. This boundary shall not be closer to the main shell of a vessel, pump, or valve tha n:

a.

the first welded circumferential joint: the weld shall be considered part of the piping.

b.

the first bolted. flange face; the bolts shall be considered part of the piping.

c.

the first threaded joint in screwed connections.

In the case of a sa fety-related valve welded to non-sa fety related pipe, the weld shall meet the requirements of the non-sa fety related piping.

In the event that the sa fety related valve is austenitic stainless steel, the connecting non-safety related weld shall also meet the requirements for the control of sensitization and delta ferrite.

For ASME Code Class 3 buttweld piping, counterboring is not necessary. When the fit-up requirements of ASME III cannot be made, taper to achieve proper alignment. In no case shall the pipe minimum wall thickness be violated.

4.

For non-Q butt weld piping, counterboring is not necessary. When the fit-up requirements of ANSI B31.1 cannot be made, the ID of the smaller pipe shall be faired to at least a 4:1 taper to achieve proper alignment. In no case shall the pipe minimum wall thickness be violated.

5.

Slight deviations may be approved by the PWE and Site Engineering.

3.3.2 Nuclear Pipe Piping shall be ground or machined when the alignment criteria cannot be obtained by the use of clamps or jacks and in accordance Appendix D, Section 3.10.

When counterboring is required, the cutting bits of the cachining tool used to end prep the piping should be set in the tool setting gauges. The wall thickness of the pipe should be measured with a calibrated micrometer before the machining tool is set up to ensure that the machining operation will not violate the minimum wall requirements.

Af ter the piping has been machined, the machined inside diameter of the pipe shall be measured by the craf tsman with the Co/No-Go gauges or other suitable means normally while the mandrel of the machining. tool is still in place.

When sleeves are installed in blockouts, their centerlines shall be within k inch of the piping centerlines.

Piping and sleeves shall be parallel within 1/16 inch of the pipe sleeve.

3.7 VALVES Valve stem orientation will normally be shown on the installation isometric. However, in some cases this may be impractical; therefore, prior to welding or bolting any valve in the system, stem orientation shall be checked against the G&H composite drawing by the PS.

Where reorientation is required to avoid interferences, valve operators.may be rotated in accordance with Site Engineering and manufacturer's instructions.

On motor-operated valves, the operator should be oriented such that the limit switch compartment is not below the gear box.

Unless otherwise noted on the installation drawing or valve body, globe valves shall be installed such that the flow enters the valve beneath the valve seat and exits above the valve seat.

When it becomes necessary as determined by the PS to install pipe spools adjacent to valves which are not available for ins talla tion, temporary spools may be installed in place of the missing valves (see Figure 6.9E-6 fcr typical valve spool configurations). Welding operations on temporary valve spool installations on "Q" lines will be inspected by the B&R Welding Engineering Department.

3.8 TEMPORARY STRAINERS Temporary strainers shall be installed as called for on the installation drawings. The strainers will remain in place until flushing is complete. The strainers shall not be removed af ter system turnover without a directive from IUGCO.
