Supply pipe
Since the 1930s, with high-quality strip steel rolling production and the rapid development of welding and inspection technology, continue to provide quality welds
Pipe
High, welded steel pipe specifications increasing and more and more areas instead of seamless steel pipe. Seam welded steel pipe according to the form is divided into Longitudinal and spiral welded pipe. According to production methods Category: Technology Category - arc welded pipe, ERW pipe, (high-frequency, low frequency) gas pipe, stove pipe. Longitudinal production process is simple, high efficiency, low cost, rapid development. Spiral welded pipe strength is generally higher than the Longitudinal, can narrow the larger diameter pipe billet production, you can also use the same width of the billet production of different pipe diameters. But with the same length of straight seam pipe compared to the weld length of 30 to 100%, and lower production rate.
