SA-333 Gr 6 · Low-temperature carbon steel pipe
An ASTM A333 Gr 6 nipple is a short length of pipe, threaded or plain, used to connect fittings, for use with ASTM A333 Gr 6 pipe. ASTM A333 Gr 6 itself is a pipe or plate specification, so the matching nipple is made to ASTM A350 LF2 — which is what we supply for A333 Gr 6 lines. Pipe nipples connect valves and fittings in small-bore lines. Swage nipples (MSS SP-95) also change size between their two ends.
