Straight Seam Welded Steel Pipe Tube
The Correct Understanding of Straight Seam Steel Pipe
Straight seam welded steel pipe is made by high frequency welding machine to certain specifications of strip steel coil into circular tube and straight seam welded steel pipe. The shape of the steel tube can be square or round can be profiled depends on the sizing rolling after welding.
The difference between seamless steel tube and straight
The difference between seamless steel tube and straight seam welded pipe in hot tension is as follows: 1, The quality of the weld directly determines the quality of the welded pipe, but also the biggest difference between the welded pipe and the seamless steel tube.
Straight Seam Welded Perforated Tube
Straight line welded perforated tubes are mostly small diameter tubes while spiral wound welded tubes are mainly big diameter pipes. This is a product with high work efficiency widely used in general industrial filter supports.
Difference between Straight Seam Welded Pipe and Spiral
Longitudinal submerged arc welded pipe and high-frequency straight seam welded pipe is different from the edge of the tube melting differentiate, the general use of arc melting is called the straight seam submerged arc welded pipe, high frequency straight seam welded pipe is the use of high frequency current melting.
High frequency welding technology for straight seam steel pipe
The longitudinal welded steel pipe is rolled into a round tube by a high-frequency welding unit and welded by a straight seam. The shape of the steel pipe can be round or square or irregular. It depends on the sizing rolling after welding.
Inspection method of straight seam welded pipe
Straight seam welded pipe is a kind of pipe which is made of hot rolled or cold rolled steel plate or steel coil and there is a straight line on the welding place so the term of the steel pipe comes from that straight line.
