SA-335 P22 · 2¼Cr-1Mo alloy pipe
An ASTM A335 P22 plug is a threaded fitting that closes a female connection, for use with ASTM A335 P22 pipe. ASTM A335 P22 itself is a pipe or plate specification, so the matching plug is made to ASTM A182 F22 — which is what we supply for P22 lines. Hex-head, square-head and round-head plugs close threaded outlets, drains and vents. Made to ASME B16.11.
