Threaded Flanges – Carbon & Stainless Steel, PN & ANSI Class, ½” to 48”

Threaded flanges, also known as screwed flanges, are designed to be connected to pipes with matching threads without the need for welding, making them ideal for systems where welding is impractical or hazardous. Manufactured from high-quality carbon steel (A105, ASTM A234, SS400) and stainless steel (SS304/L, SS316/L) materials, these flanges conform to industry standards and are suitable for a wide size range from ½” (15 NB) up to 48” (1200 NB). They are rated for pressure classes spanning from PN6 to PN40 and ANSI ratings from 150 lbs to 1500 lbs, meeting the requirements for a variety of industrial, petrochemical, and oil & gas applications. These flanges provide reliable sealing with threaded pipe connections and are widely used in maintenance-intensive or temporary piping setups.
