AISI 904L Threaded Pipe Fittings

Threaded Pipe Fittings

AISI 904L Threaded Pipe Fittings covers a group of high pressure pipe fittings manufactured out of forged 904L materials. This includes 45 degree elbow, 90 degree elbow, straight and reducing tee, cross, full couplings, half couplings, boss, cap, couplet, plugs and bushings. These type of fittings are ideal for small sized pipelines from 1/8” to 4” NPS with high pressure retaining capacity.

Anand Steels produces and supplies AISI 904L threaded pipe fittings to suit ANSI/ASME B16.11 pressure class 3000 and 6000. AISI 904L threaded pipe fittings are manufactured to ASTM A182/A182M F904L material specification Stainless steel 904L screwed pipe fittings are duly marked for traceability. We offer worldwide shipping by Sea or Air freight options.
