EN10216-5 Round Tubing SRL DRL 40Ft Duplex Seamless Stainless Steel Pipe
Product Information:
A seamless stainless steel pipe is a tubular product made from stainless steel using a seamless manufacturing process.
Seamless pipes have a uniform structure with no weak points at welded seams, making them stronger and more reliable.
Seamless stainless steel pipes are available in various grades and alloys to suit different applications and environments. Common grades include 304/304L, 316/316L, 321, and 904L. Different alloys offer specific properties such as enhanced corrosion resistance, high-temperature resistance, or improved mechanical strength.
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.
