How to ensure the quality of ERW steel pipe

  The advantages of this ERW steel pipe processing technology are that there is a heat treatment process after welding to eliminate the residual stress in the weld and heat affected areas, to refine the grain, and to make the heat affected zone of the weld small, and the heating speed is fast, thus greatly improving the welding speed and welding quality, and can be used as a blank without pickling, shot peening and trimming. At the same time, it can weld alloy steel, high alloy steel and non-ferrous metal pipe, greatly reducing unit power consumption. A set of welding equipment can be used to produce each.   The advantages of this ERW steel tube processing technology are that there is a heat treatment process after welding to eliminate the residual stress in the weld and heat affected areas, to refine the grain, and to make the heat affected zone of the weld small, and the heating speed is fast, thus greatly improving the welding speed and welding quality, and can be used as a blank...

Carbon steel seamless connection method

  There are many ways to connect carbon seamless steel pipe, and now several commonly used methods are listed:   a, compression type; b, live connection; c, compression; d, push; e, taper thread; f, socket welding; g, live flange connection; welding and welding and the traditional combination of the derivative Series of connections.   Different connections, because of their different production principles, their application areas are also different, but generally speaking, one thing in common is that it is convenient to install, reliable and reliable.   Here are some more common links to make a brief introduction:   1. compression: insert the tube into the pipe, fasten it with the nut, compress the mouth of the casing through the seal ring with the screw force, and seal the function, then the connecting pipe can be completed.   2.flanges: flanges and pipes are used for TIG welding, fastened with fasteners or bolts, sealing between flanges and sealing.   3. welding type: pip...
