Duplex Steel Flanges

Blossom Steel & Engineering Co. is a trusted supplier of Duplex Steel Flanges, manufactured using premium-grade raw materials to ensure superior performance and reliability. Our extensive product range includes high-quality duplex stainless steel flanges that are widely used across demanding industrial applications and are known for their durability, strength, and cost-effectiveness. Duplex steel flanges are highly valued for their exceptional mechanical strength and outstanding corrosion resistance, making them ideal for use in harsh and aggressive environments. These flanges combine the advantages of both ferritic and austenitic stainless steel, offering excellent resistance to stress corrosion cracking, pitting, and crevice corrosion. This unique metallurgical structure also provides higher tensile strength compared to conventional stainless steel flanges. As a result, duplex flanges are extensively used in oil & gas, chemical processing, petrochemical, marine, and offshore industries, where high pressure and corrosion resistance are critical.

At Blossom Steel & Engineering Co., our duplex stainless steel flanges are available in a wide range of sizes, pressure ratings, and international standards to suit diverse project requirements. We supply various flange types, including Weld Neck, Slip-On, Blind, Threaded, and Socket Weld flanges, ensuring complete flexibility for our customers. All products are manufactured and supplied in strict compliance with industry specifications. We are committed to timely delivery, competitive pricing, and excellent customer support. Our experienced team is always available to assist clients in selecting the right duplex steel flange solutions for their specific applications.
