An ASTM A335 P22 anchor flange is a forged ring welded into a pipeline to fix it to a structure, for use with ASTM A335 P22 pipe. ASTM A335 P22 itself is a pipe or plate specification, so the matching anchor flange is made to ASTM A182 F22 — which is what we supply for P22 lines. Anchor flanges restrain pipelines against thrust and movement — at pump stations, river crossings and pig traps. They are made to project drawings.
