SA-335 P22 · 2¼Cr-1Mo alloy pipe
An ASTM A335 P22 nipple is a short length of pipe, threaded or plain, used to connect fittings, for use with ASTM A335 P22 pipe. ASTM A335 P22 itself is a pipe or plate specification, so the matching nipple is made to ASTM A182 F22 — which is what we supply for P22 lines. Pipe nipples connect valves and fittings in small-bore lines. Swage nipples (MSS SP-95) also change size between their two ends.
