Thick-walled pipe Spot | Xin pipe (certified) | thick-walled pipe

 Liaocheng Xin welded steel pipe, also known as welded pipe, which is cut into narrow steel strip by strip 16mn thick-walled pipe, then wrapped into a tubular mold cold. Then followed by a special welding seam welded pipe. Welds polished bright outside. Burr general pipe is not playing. Only precision pipe before playing in the burr. Corrosion point: welded steel pipe refers to a steel strip or plate bending round, square and other shapes and then welded into the surface jointed pipe. By arc welding processes can be divided into the pipe, high-frequency or low frequency electric resistance welded pipe, gas pipe, stove pipe, Bundy tubes. Longitudinal welds can be divided according to the shape and spiral welded pipe. Welded steel pipe used in oil drilling and machinery manufacturing. Stove pipe can be used as water and gas pipe, large diameter welded pipe for high pressure gas transmission, etc; spiral welded pipe for the oil and gas transportation, piles, piers, etc. Seamless steel tubes welded steel pipe is lower than cost, high production efficiency. Welded steel pipe in the form of divided Longitudinal seam welded steel pipe and spiral welded pipe, also known as q345c thick-walled pipe, steel pipe with a steel plate or strip after curl forming welded steel. Welded steel pipe production process is simple, high production efficiency, different specifications, equipment owned less q235b thick-walled pipe, but the general strength of less than seamless steel tubes. Since the 1930s, with the progress of high-quality steel rolling production and the rapid development of welding and inspection techniques, and continuously improve the quality of welds, welded steel pipe increasing varieties and specifications, and in more and more areas instead of nothing pipe joints. Welded steel pipe welds in the form of divided Longitudinal and spiral welded pipe. In order to achieve the desired effect of rust, should be based on the appearance of hardness Longitudinal equipment, raw rust level, requiring the appearance of roughness, abrasive coating types to choose, for a single-layer epoxy, two or three layers of polyethylene-coated layer, using a mixture of grit and steel shot abrasive rust more easily achieve the desired effect. Shot has strengthened the role of the steel surface, while the role of grit is etched steel surface. Mixed abrasive grit and steel shot (usually Shot hardness hardness 5060HRC 4050HRC grit can be used for a variety of steel surfaces, even with the C and D grade steel surface rust, rust effect is also very good thick wall pipe spot | Xin pipe (certified) | thick-walled pipe provided by Liaocheng Poly Pipe Manufacturing Co., Ltd.
