The steel welded pipe is made from hot rolled steel strip, so the application scope of the tube is greatly expanded. It is mainly used for construction, machinery manufacturing, solar power support, steel structure engineering, power engineering, agricultural and chemical machinery, car chassis, airport etc.
S355 structural steel is a high-strength low-alloy European standard structural steel covering four of the six “Parts” within the EN 10025 – 2004 standard. With minimum yield of 50,000 KSI, it meets requirements in chemistry and physical properties similar to ASTM A572 / 709. Careful attention should always be placed on the specific variation of S355 required if considering substitute material.
Factory testing of welded steel pipe s235jr s275jr s355jr:
With advanced machine, We can check chemical component, mechanical property, water pressure, etc.
Regular inspection: diameter, wall thickness, length, welding range, surface, etc.
