Duplex Steel Welded Pipe

Duplex Steel Welded Pipe

Duplex steel welded pipes are pipes made from duplex stainless steel (DSS) with a welded seam. They combine high strength, excellent corrosion resistance, and cost-effectiveness compared to seamless pipes in certain applications.They are used in a variety of applications including pipelines, pressure vessels, boilers, tanks, and condensers. Duplex steel welded pipes are also used in the construction industry for a variety of purposes such as structural frames, piping systems, and for other general fabrication purposes.
