Seamless Pipe VS Welded Pipe

Date:2018-01-18    View:386      Tag:Seamless Pipe VS Welded Pipe

The main difference between seamless steel pipe and welded pipe is the molding process. Generally welded steel pipe, such as water pipes, are usually bent and welded together by a flat plate, after which you can find a seam; the diameter is usually a spiral weld. Seamless liquid steel pipe is usually through the annular gap melt state, and then through the extrusion backlog of the molding process, so there is no seam. In terms of performance, especially compared with the welded steel, greatly improving the carrying capacity, often used in high-pressure equipment. Hydraulic equipment, such as pipe connections. Welded steel pipe welding area is the weakest link, weld quality is also the main factor affecting the overall performance. Welded steel pipes in the north usually have water pipes or heating pipes that burst and are generally welded in the cold experiencing an explosion in winter.


Seamless steel pipe perforated hole production of steel. Welded steel pipe into a barrel and then welded. According to its production of seamless steel pipe and welded pipe method is divided into two. Seamless steel pipe using high-quality carbon steel or alloy steel, hot-rolled, cold-rolled (pull) points. Welded steel rolled into the tube plate, weld or spiral seam welding, in the manufacturing method, is divided into low pressure fluid welded steel pipe, spiral welded steel pipe, straight seam welded pipe, welded pipe. Seamless steel pipe can be used for a variety of liquids, gas pipelines. Welded pipe can be used for water pipes, gas pipes, heating pipes. Seamless steel pipe for important applications, such as pipes, barrels and other uniform, high pressure. General use of high-quality steel, alloy steel or even. The general purpose of the general use of steel compression steel, such as water pipes, gas pipes and so on
