Industrial THDRF 150 B16.5 F304 304L SA A183 CH-9153 Threaded Flange

Chandan Steel’s 3-inch THDRF 150 B16.5 Threaded Flange is a forged stainless-steel flange designed for threaded pipe connections in Class 150 service. Made from F304/F304L stainless steel and forged to ASTM SA A183 CH-9153, this flange conforms to ASME B16.5 for a 3-inch nominal pipe size and a Class 150 rating. The THDRF designation denotes a threaded flange configuration compatible with standard mating flanges and bolts for gasketless, quick-disconnect piping joints. The part is identified internally as CH-9153, enabling precise sourcing across orders. With the corrosion resistance and formability of 304/304L stainless steel, this flange is suitable for general industrial applications where stainless service is preferred, and it aligns with supplier catalogs that list THDRF flanges in 1/2" to larger sizes across 150 to higher pressure classes. This 3" THDRF 150 flange provides a code-compliant, ready-to-install threaded connection for stainless piping systems.
