AISI 904L Butt Weld Pipe Fittings
AISI 904L Butt-Weld Pipe Fittings covers a group of pipe fittings manufactured out of wrought and forged 904L materials. This includes 90 degree elbows, 45 degree elbows, 180 degree bends, concentric and eccentric reducers, straight and reducing tees, end caps and stub ends. As the name suggests this type of fittings range is usually welded to pipes or to each other at its butt with proper alignment tools and use of filler metal.
Anand Steels produces and supplies AISI 904L butt-weld pipe fittings in seamless, ERW, mitered joints or other welded construction. AISI 904L butt-weld pipe fittings are manufactured to ASTM A403 WP904L material specification and ANSI/ASME B16.9, B16.28, ISO 5251, BS 1640 and EN 10253 standards; heavy walled forged butt weld 904l pipe fittings are manufactured to ASTM A182/A182M F904L material specification. Stainless steel 904L butt-weld pipe fittings are duly marked for traceability. We offer worldwide shipping by Sea or Air freight options.
