Duplex Steel Welded Pipe

Duplex Steel Welded Pipes are engineered to provide an optimal balance of high mechanical strength and exceptional corrosion resistance, making them a preferred choice for demanding industrial applications. These pipes are manufactured using advanced welding techniques and high-quality duplex stainless steel alloys, which combine the best properties of austenitic and ferritic steels. As a result, they exhibit superior strength, toughness, and resistance to stress corrosion cracking compared to conventional stainless steels.

Due to their robust properties, duplex steel welded pipes are extensively used in the chemical processing industry, where they withstand aggressive chemicals, high temperatures, and high pressures. Their excellent corrosion resistance ensures long-term durability in environments involving acids, chlorides, and other corrosive agents, reducing maintenance and replacement costs.

Huashang ensures that all our duplex steel welded pipes comply with international standards and undergo rigorous quality testing, including tensile strength, toughness, and corrosion resistance assessments. Our commitment is to provide clients with durable, reliable, and high-performing piping solutions that meet the rigorous demands of their specific industries and projects.
