PRESSURE TESTING OF CLEANED / DEGREASED STEEL GATE, GLOBE, CHECK AND BALL VALVES

having flanged, screwed, socket weld ends, butt weld ends and valves with extended pipe end pups.

Carried out in Adanac's cleanroom using Nitrogen, Helium and Nitrogen/Helium mixture,providing pneumatic testing to 350 BAR.

Adanac procedure HPT/02/93 covers valves having pressure- temperature rating designated by ANSI class and by PN.

Typically NPS 1/2"- 20" class rating 150 - 1500lb. PN10 - 100.

This procedure meets many requirements including those of: Adanac degreasing procedure DV/101/89 and DV/102/02 Air Product's specifications LO5 and LO6 BOC specification 50000810- oxygen clean
