ANSI threaded flanges are designed to connect pipes through threaded joints, making them suitable for piping systems where welding is impractical or needs to be avoided. Manufactured to ASME B16.5, they are available in nominal sizes from 1/2" to 24" and pressure classes from Class 150 to Class 2500, subject to applicable size and pressure-class limits.
Jinhang Pipeline supplies threaded flanges in carbon steel, stainless steel, and alloy steel, including ASTM A105/A105N, A182 F304/304L, F316/316L, F321, and F11/F12/F22. Custom material selection and specifications are available to meet project requirements. Size, pressure class, material grade, and thread specifications can be confirmed according to the intended application.
