  API 5L Gr. B X42 Welded Steel 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 percent of the production rate is low. Therefore, the welded steel pipe actually use straight seam welded, welded steel pipe is mostly used. Bank has increased the intensity of the mortgage, since the second half of 2018 since the financial crisis. And steel companies to give preferential interest rates, many steel projects of its own funds rate has decreased, but the steel industry faces overcapacity and eliminate backward and other problems, naturally become one of the main targets of the credit crunch, however, iron and steel enterprises, especially large steel companies are not short of money "often warm extrusion, straight seam steel pipe production technology: The strip coil as a raw material for automatic double-sided submerged arc welding process wire spiral seam welded steel pipe production efficiency is high.
