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.
