AISI 904L Socket Weld Flanges
AISI 904L Socket Weld Flanges are ring type flange with step designed at the ID of the flange to be used to receive the pipe for welding. Designed for smaller pipe size for high pressure applications, these 904l socket welding flanges are available from ½” to 24” in ANSI/ASME Pressure class 150/300/400/600/900/1500 and 2500.
Anand Steels is a manufacturer, stockist and supplier of AISI 904L socket weld flanges. AISI 904L socket weld flanges are manufactured by means of hot forging and machining to required dimensions. Forged 904l socket weld flanges conforms to requirement of ASTM A182 F904L material specification and dimensions to ANSI/ASME B16.5, BS 1560, EN 1092-1, API 6A, 6B, 6BX, ISO, GOST and various DIN standards. AISI 904L socket weld flanges can also be manufactured from thick plates to ASTM A240/A240M Type 904L (UNS N08904) material specification. Stainless steel 904l socket weld pipe flanges are duly marked for traceability. We offer worldwide shipping by Sea or Air freight options.
