' 2 of 3 CP-CPM 10.2 2 7/12/83 All other stainless steel piping and equipment shall meet the acceptance criteria stated in Section 2.0.

Non-Westinghouse supplied equipment is identified by tag numbers prefixed with CP1, CP2, or CPX. West.inghouse supplied equipment is identified with TBX or TCX tag number prefixes.

For stainless steel piping and equipment that will be insulated with reflective insulation, acceptance of cleanliness shall be documented by Brown & Root QC in accordance with QC procedures.

2.0 PROCEDURE 2.1 CLEANING Stainless steel piping and equipment surfaces within the scope of this procedure shall be cleaned to the extent necessary to ensure the criteria discussed below are obtained. Cleaning may be per-fonned by vacuuming, wiping, or blowdown with compressed air, and flapping / grinding. Welds which have received preservice exami-nation shall not be cleaned by grinding or flapping. When compressed air is used, care shall be taken to prevent contamination of other items in the area. All stainless steel items shall be given a final rinsing with Grads "A" water.

The external surfaces shall meet the following criteria:

1. The surface shall be free of particulate contaminants such as sand , metal chips , weld siag , etc.

2. The surface shall be free of organic film contamination such as oils and preservatives as determined by visual examination. If surfaces fail to meet this criteria, and degreasing is required, use Stoddard solvent, mineral spirits, isopropyl alcohol, ethyl alcohol, acetone, toluene, methyl ethyl ketone, or an approved liquid penetrant cleaner to clean the surface. De-greasing shall be followed by rinsing with Grade "A" water.

3. Paint on stainless steel pipe surfaces shall be treated as follows:

a. On piping systems with a design temperature of 300 F or less:

1) All paint on surfaces that is visible and accessible shall be removed. ];

2) Surfaces for which visual inspection is not feasible .!I (such as adjacent to pipe supports), pressure spraying with all the following liquids shall be used to clean

-- the pipe: i 1

b. On piping systems with a design temperature greater than 30TF:

1) All paint on surfaces that is visible and accessible shall be removed.

2) On surfaces for which visible inspection is not feasible, a dark abrasive cloth shall be used to clean the surfaces.

If paint shows on the cloth, a new clean cloth shall be used until all paint is removed from the pipe. If it is not possible to satisfactorily remove the paint in this manner, the p1pe surface snall be made accessible f r pair.t removal by dismantling pipe supports as necessary.

3) Following any paint removal, pressure spraying with all the following liquids shall be used to clean the pipe:

First, MEK, or approved liquid penetrant cleaner; i ,

next, acetone or ethyl alcohol; and finally de-

'- mineralized water.

2.2 INSTALLATION Only the following products may be used on stainless steel piping and equipment:

1. Calcium silicate, all types

2. Ryder thermocote cement, all types

3. Temp mat

4. Aluminum lagging with moisture barrier, all types

5. 81-27 foster adhesives

6. fiberglass, KNAJF pipe and block types only.

When installing the insulation, the craftsman shall take care not to contaminate the cleaned surfaces or the insulation.

Insulation contaminated with mud, paint, grease, etc. shall not be applied to stainless steel surfaces.
