High-frequency welded pipes are generally straight-slit, but straight-slit welded steel pipes are not necessarily high-frequency welded. The high-frequency straight-slit electric resistance welded steel pipe is formed by the skin effect and the proximity effect of the high-frequency current after the hot-rolled coil plate is formed by the molding machine, and the edge of the tube blank is heated and melted, and pressure welding is performed under the action of the pressing roller to realize the production. The high-frequency resistance welded steel pipe is different from the ordinary welded pipe welding process. The weld is made of the base material of the steel strip body, and the mechanical strength is better than that of the general welded pipe. The surface is smooth, high precision, low cost, and has low weld seam height, which is beneficial to the coating of 3PE anti-corrosion coating.

Longitudinal submerged arc welded is produced by using a single medium and thick plate as the raw material, pressing (rolling) the steel plate in a mold or forming machine into a tube blank, using double-sided submerged arc welding, and expanding the diameter. The steel plate feed amount can be automatically adjusted according to different steel grades, wall thicknesses, and plate widths. At the same time, the deformation compensation function effectively avoids the adverse effects of mold deformation on the forming and ensures the flatness of the full length of the steel plate during the pressing process. The feeding step is uniform during forming, ensuring the roundness of the tube blank and the flatness of the welding edge. The finished product has a wide range of specifications, and the weld has good toughness, plasticity, uniformity, and compactness. It has the advantages of large pipe diameter, pipe wall thickness, high-pressure resistance, low-temperature resistance, and strong corrosion resistance.

Spiral welded pipe(SSAW pipe, also called HSAW pipe). The pipe is formed by spiral submerged arc welding technology. Spiral welded pipes are formed using narrower plates or hot rolled coils, which lowers their production costs significantly. The welding line is shaped like a helix. The spiral welding process permits the production of large-diameter pipes suitable for transporting large volumes of oil and gas. Some SSAW pipes were historically limited to low-pressure applications.

Steel pipes

Welded steel pipe, like common ERW steel pipe, cannot ignore the trouble about cutting. And this is an essential step for the whole tubeâ??s production process. For manufacturers, they have to pay attention to that as a poor cut can lead to poor fit-up steel pipe. What effects are when there is poor cut. In general, a poor cut can lead to poor fit-up and create unnecessary gaps. More over, for some special steel tube, like stainless steel pipe with corrosion-resistant pipe, this would lead to distortion which may affect the corrosion-resistant quality. Of course, poor preparation also leads to longer weld cycle times, higher consumable costs and potential repairs. Thus, it would have influence for a pipeâ??s quality. How to solve this trouble for welders? A necessary cutting equipment would be the first step. For example, buying dedicated orbital pipe cutting equipment to guarantee cuts within mere thousandths of an inch of the specified parameters maybe one of the steps. Of course, the skilled experience for welder is also important.

We choose a kind of steel pipe due to its practical function. No matter seamless steel pipe or welded one, its features would finally determine its work environment. Today, we would like to discuss about the elements increasing hardness of abrasion resistant steel pipe. What makes abrasion resistant steel more immune to wear than other types of steel? And how we guarantee its quality when used in tubes? The chemical composition of abrasion resistant steel would give us answers. Some alloys would increase the ability of abrasion resistance. For example, carbon will help block dislocations, thus, it will enhance the hardness and strength of a steel pipe. The added carbon also allows the steel to form microstructures with increased hardness when heated and quenched. There are other elements that can be added to abrasion resistant steel to increase its hardness value too. Chromium and manganese are also added to abrasion resistant steels to help reduce the negative effects caused by wear.

The hot expanded seamless steel pipe is relatively low density but the contraction of the strong seamless steel pipe can be referred to as thermal expansion. The roughing finishing process for expanding the diameter of a pipe by a cross-rolling method or a drawing method. Steel pipe thickening in a short period can produce non-standard and special types of seamless tubes with low-cost and high production efficiency, the current international developments in the field of tube rolling.

Seamless steel pipe is hollow section, a large number of used for conveying fluid pipe, such as oil, natural gas, coal gas, water and some solid materials, such as pipelines. Compared to the steel pipe and round steel solid steel bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used with steel pipe manufacturing annular parts, such as can improve material utilization, simplifying the manufacturing process, material saving and processing time, has been widely used to make steel pipe. carbon steel seamless pipe wholesale: Cangzhou Weiheng Pipe Industry Co., Ltd.
