EN 10219 S355JRH grade spiral steel pipe is made of carbon steel, which contains various elements such as carbon, silicon, manganese, phosphorus, sulfur and niobium. They come in a wide range of outer diameter sizes, ranging from 21.3mm to 457.2mm, while wall thickness ranges from 1.8mm to 14.27mm. The circular size of this steel pipe ranges from 26.9mm to 323.9mm, and comes in various shapes, including round pipes, square pipes, rectangular pipes, etc.
S355JRH spiral welded pipe has excellent mechanical properties, with a minimum yield strength of 355MPa, a minimum tensile strength of 680MPa, and an elongation at break of 20%. In order to meet the needs of different application scenarios, EN 10219 S355JRH welded steel pipes also provide a variety of pipe ends and coating options, which not only prevent corrosion but also increase wear resistance.
