Spiral Steel Pipes for Sales from leading Spiral Steel high strength spiral welded steel pipe

At the first, the spiral welded steel pipe meets to high strength comparing with longitudinal welded pipe. The second, according to the test of relevant research institutes in the United States, although the spiral welded pipe and the straight welded pipe(ERW pipe) are in the same grade, the spiral welded steel pipe has higher impact toughness.Spiral Welded Pipe Manufacturing Process - Spiral Welded high strength spiral welded steel pipeSpiral welded pipe manufacturing process is important to ensure the excellent mechanical performance, high quality, longer lifespan even the competitive cost of the spiral steel pipe. The s piral welded pipe is also called spiral steel pipe, spiral welded tube or spiral welded steel pipe, etc.Generally speaking, t he spiral welded pipe takes mild or carbon steel strip coil as raw material high strength spiral welded steel pipeSpirally welded steel pipes - ArcelorMittal PilingThe result of the multi arc welding on both sides of the coil is a full penetration weld of a very high quality produced in a cost effective way. The flexibility of the mill is very high because of the use of this system. A large range of coil thicknesses (between 10 and 25mm) can be transformed in spirally welded pipes

While many pipe manufacturing methods exist, the most prominent discussion in the industry compares electric resistance welded (ERW) vs. seamless (SMLS) steel pipe.

What is a Welded Steel Pipe? About Welded or ERW Steel high strength spiral welded steel pipe

Welded pipe (pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp that are formed, bent and prepared for welding. The most popular process for large diameter pipe uses a longitudinal seam weld. Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp.
