Stainless Steel Flanges

ASTM A182 STAINLESS STEEL FORGED FLANGES
Product Descriptions

Stainless steel forged flanges are known for their exceptional corrosion resistance, high strength, and durability. They are designed for both high-temperature and low-temperature and for high-pressure applications, making them suitable for demanding environments. These flanges are stocked primarily in F304/L and F316/L, each offering specific properties tailored to different industrial needs. Their welded ends and seamless construction ensure leak-proof connections, and they are widely used in industries like oil and gas, chemical processing, power generation, water, and food and beverage industries.

SPFA stock a core range of common standards and sizes, many of which are certified to multiple dimension and material specifications when the standards overlap. Many of the larger sizes are stocked in a semi-finished very heavy wall and are machined according to the required finished size, face and weld prep.
