SS 904L Threaded Flanges
SS 904L Threaded Flanges are ring type flange with female pipe threads machined on its ID to receive a mating male pipe threaded pipe. Designed for smaller size and low pressure piping, these threaded flanges can come very handy while maintenance.
Anand Steels is a manufacturer, stockist and supplier of SS 904l threaded flanges. These 904l threaded flanges come with flat face, raised face or ring type joint configuration. SS 904L threaded flanges are manufactured to ASTM A182 F904L forged material specification and ANSI/ASME B16.5, B16.36, B16.47 Series A, Series B, B16.48, BS 10, BS 1560, EN 1092-1, API 6A, 6B, 6BX, ISO, GOST and various DIN standards. SS 904L threaded flanges can also be manufactured by merely machining heavy gauge plates to ASTM A240/A240M Type 904L (UNS N08904) material specification. Stainless steel 904l threaded pipe flanges are duly marked for traceability. We offer worldwide shipping by Sea or Air freight options.
