No Comments. Longitudinal seam steel pipes can be divided into electric resistance welded straight seam steel pipes and submerged arc welded straight seam steel pipes in terms of welding process. Among them, electric resistance welded straight seam steel pipes are divided into high frequency welded straight seam steel pipes, medium frequency welded straight seam
passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.A plate rolled to become a pipe and welded using the Electric Resistance Welding process.ERW steel pipe/tube making machine for round, square and Straight Seam Steel Pipe Forming ProcessERW steel pipe/tube making machine, the process is unwinding the steel coil and make the head and tail of the coil butt-welded in the strips preparation section. Then the strips fed into accumulator and pulled out of the accumulator at a constant speed passed through the unit. Next, the strip is formed into an open tube in the forming unit.How to choose high quality straight seam welded pipeWhen choosing a straight seam steel pipe, we must first pay attention to the material. When we inspect the goods, we must first determine whether the material is qualified. The second is to see if the wall thickness of the straight seam steel pipe reaches the required wall thickness. Whether the tolerance is within the national requirements.
The JCOE manufacturing technology is a welded pipe forming process developed in the 1990s, during the molding process, it is the first steel plate edge milling preflex by longitudinal edges (or planing), and then type J C O the order of the type of molding, in each step stamping expressed in three-point bending as the basic principle.LSAW Steel Pipe, DSAW Steel Pipe, Straight Seam Welded Straight Seam Steel Pipe Forming ProcessLSAW steel pipe, hot-rolled or cold-rolled steel sheet or steel coil made of steel pipe welding equipment in the straight seam welding are called the straight seam welded pipe. It is cut into strips by a steel strip, and then wrapped into a tubular cold mold. Then a special welder and then a seam welded. Outer weld brightly polished.LSAW Welded Steel Pipe Features and Manufacturing Process5. Pre-welding This is to make a welded pipe steel a straight seam after it has been formed and then use gas welding seam (MAG) for continuous welding. 6. Inside weld This is done with a tandem multi-wire submerged arc welding (about four wire) on the inner part of the straight seam welded steel pipe

Welded steel pipe is divided into straight welded pipe and spiral welded pipe according to the form of welding seam. The blank used for welding steel pipe is steel plate or strip steel, which can be divided into furnace welded pipe, electric welding (resistance welding) pipe and automatic arc welding pipe due to different welding processes. Due to the different welding forms, it is divided into two types straight Precautions during Maintenance of Straight Seam Steel Pipe Straight Seam Steel Pipe Forming ProcessStraight seam steel pipe is a kind of welded steel pipe. After forming a hot-rolled steel coil by a forming machine, the steel coil is transformed into a cylindrical shape. The high-frequency current skin effect and proximity effect or arc combustion under the flux layer are used for welding, so that the edge of the tube blank is heated and melted under a certain extrusion pressure and finally cooled and formed.Production process of spiral seam Straight Seam Steel Pipe Forming Process - nan-steelProduction Process. 1.Raw materials are strip steel coils, welding wires, and fluxes. Strict physical and chemical tests are required before investment. 2.Butt joint of strip steel head and tail, adopt single wire or double wire submerged arc welding, after coiling into steel pipe, adopt automatic submerged arc
In continuous pipe forming process, uncoiled strip material is taken from an accumulator, with the leading end and the trailing end of the consecutive coils being welded together. In single pipe forming process, the pipe forming and welding operation is carried out in single pipe length.Products, ERW DSAW SMLS pipe Weiler Pipe llc.DSAW PIPE Double Submerged Arc Welded (DSAW) is manufactured by first forming steel plates into cylindrical shapes. The edges of the rolled plate are formed to produce v-shaped grooves on the interior and exterior surfaces at the seam. The pipe seam is then welded by an arc welder in a single pass on the interior and exterior surfaces.Straight Seam Steel Pipe Forming Procstraight seam pipepipe seam typepipe seam weld typesweld seam pipelock seam pipe
