High frequency welded steel pipe: It is a product produced by using the skin effect and proximity effect of high-frequency current to heat and melt the edge of the pipe blank after hot rolled coil is formed by a forming machine, and then pressure welding is carried out under the action of an extrusion roller. High frequency welded steel pipes have the characteristics of relatively simple process and rapid continuous production, and are widely used in civil construction, petrochemical, light industry and other sectors. It is commonly used for transporting low-pressure fluids or making various engineering components and light industrial products.

The production process of high-frequency welded steel pipes mainly depends on the product variety. From raw materials to finished products, a series of processes are required. To complete these processes, various mechanical equipment, welding, electrical control, and detection devices are needed. These equipment and devices are arranged reasonably according to different process requirements.

High frequency welded steel pipe: High frequency resistance welded steel pipes have a different welding process from ordinary welded pipes. The weld seam is formed by melting the base material of the steel strip body, and the mechanical strength is better than that of ordinary welded pipes. High frequency welded steel pipes are produced by using the skin effect and proximity effect of high-frequency current to heat and melt the edges of hot-rolled coils after they are formed by a forming machine, and then pressure welding is carried out under the action of extrusion rollers.

High frequency welded steel pipe: with a smooth appearance, high precision, low cost, and small weld seam height, it is conducive to the coverage of 3PE anti-corrosion coating. There are significant differences in the welding methods between high-frequency welded steel pipes and submerged arc welded pipes. Due to the fact that welding is completed instantly at high speeds, the difficulty of ensuring welding quality is much higher than that of submerged arc welding. High frequency welding of steel pipes is reliable and durable in quality.
