DSAW pipe is used in high-pressure gas and oil transmission lines (both onshore and offshore), structural members and pipe piles. Spiral Weld Pipe. Spiral Weld Pipe, as the name implies, is a steel pipe that has a seam running its entire length in a spiral form. In the past, due to the method of manufacture, Spiral Welded pipe was relegated to Noksel España Spiral welded steel pipe manufacturerNoksel España manufactures spiral welded steel pipe for water system transmissions, oil and gas conveyance, infrastructure projects, piling industries, casing piles, and marine and port works.We have worked around the world thanks to our experienced career in steel pipes production. We work to produce a high-quality product:an efficient solution with a long operational life. Products - Pipe and TubesNIPPON STEEL VIETNAMSteel Pipe Pile. Steel pipe piles are high quality with automatic spiral welding technology and pipe diameter from 600 ~ 3,000mm with thickness 6 ~ 25.4mm. Widely used in ports and harbors (Jetty and breakwater), piles can be easily penetrate into ground. Steel Pile Pipes help to increase horizontal bearing capacity due to high bending strength.
Spiral welded pipe (SSAW/SAWH):a low carbon carbon structural steel or low alloy structural steel strip is rolled into a tube blank at a certain spiral angle (forming angle), and then the tube seam is welded together. It can be made with a narrower strip Steel produces large diameter steel pipes. Its specifications are eed by outer diameter * wall thickness, and the welded pipe shall be Spiral Welded Pipe Manufacturing ProcessSpiral welded pipe unit The spiral welded pipe unit is used to produce large-diameter steel pipes with a diameter of (892450)mm×(0.525.4)mm and a length of 635m. The production method is continuous and discontinuous. The unit adopts spiral forming, and the welding adopts two steps of pre-welding and final welding.
