EN10216-5 Round Tubing SRL DRL 40Ft Duplex Seamless Stainless Steel Pipe
Product Information:
A Duplex Seamless Stainless Steel Pipe is a type of pipe made from duplex stainless steel, which combines the benefits of austenitic and ferritic stainless steels. These pipes are known for their excellent corrosion resistance, high strength, and resistance to stress corrosion cracking.
Duplex stainless steel is a two-phase microstructure consisting of roughly equal parts austenite and ferrite.
Alloying Elements: Common alloying elements in duplex stainless steels include chromium, nickel, molybdenum, and nitrogen, which contribute to their corrosion resistance and mechanical properties.
Seamless pipes are manufactured without welded joints along the length, providing a smooth internal surface that minimizes turbulence and pressure drop in fluid flow.
