2 REQUIREMENTS
2.1 Dimensions
All dimensions for stainless steel pipe, fittings, drains. and adapters are found in Tables I through 47. All threaded inch values shall comply to ASME BI.20.1. Threaded dinsensions shall be identified as either “inch dirnen’iions’ according to ASME BI.20.I or “standard metric thread” depending on which thread is used for the particular threaded connection.
2.2 Tolerances. Dimensions, Other Patterns. and Interchangeability
Other patterns of pipe and fittings not specifically found within this Standard shall meet the dimensional quirements of Table 1.
2.3 Alloys
The pipe shall be produced by the welding of sheet steel produced in accodaiice with the grading of alloy as described by the Iron and Steel Society US S30400, 1\pe 304 and LJNS S31603, Type 3161. The chemical composition of which is in accordance with the applicable standard. Type 304 shall be used (or above—ground applications. Only Type 3l6l shall be allowed above ground, used for below-ground applications. or where the discharge effluent requires Type 3161. See the manufacturers’ recommendations for application. When requested by the purchaser. the fabricator of the pipe and fittings shall furnish certifications from the steel manufacturer that the pipe and fittings were manufactured from Type 304 and 1’pe 3161 stainless steel alloy as required by this Slandard.
2.4 Welded Fabrication
After fabrication, welded components shall be treated to remove discoloration and contaminates by being pick. led and pasivated or by other means such as grinding and polishing so that the discoloration and contaminations from welding are removed Burrs, edges, and irregularities in the welding scam area shall not exceed 03 mm (0.012 in.), Pipes and fittings shall be tested In accordance with performance tests found in para. 3.4.
2.5 Straightness of Pipe
Pipes shall be straighi Measured along the pipe barrel, the deflection over the length of the 1-rn (3’L4-in) section shall not deflect more than 1.5 mm (0.06 In.) in the middle.
