High frequency welded steel pipe: It is the product of a hot rolled coil plate after forming machine, using the skin effect and proximity effect of the high-frequency current so that the edge of the tube billet is heated and melted, and the pressure welding is carried out under the action of extrusion roller to achieve production. High-frequency welded steel pipe has the characteristics of a relatively simple process and rapid continuous production, which is widely used in civil construction, petrochemical, light industry, and other departments. It is mainly used for conveying low-pressure fluid or making various engineering components and light industrial products

The production process of high-frequency welded steel pipe mainly depends on the product variety, from raw materials to finished products need to go through a series of processes, to complete these processes need the corresponding various mechanical equipment and welding, electrical control, testing devices, this equipment, and devices in accordance with different process requirements have a variety of reasonable layout.

High-frequency welded steel pipe: high-frequency resistance welded steel pipe, and ordinary welded pipe welding process is not the same, the weld is made of the base metal of the steel belt body melting, mechanical strength than the general welding. A High-frequency welded steel pipe is a hot rolled coil plate after a molding machine, the use of high-frequency current skin effect and proximity effect, so that the edge of the tube billet heating melting, pressure welding under the action of extrusion roller to achieve production.

High-frequency welded steel pipe: smooth appearance, high precision, low cost, small weld residual height, favorable 3PE anticorrosive coating. The welding method of high-frequency welded steel pipe is significantly different from that of submerged arc welded pipe. Because the welding is completed instantaneously at high speed, the difficulty of ensuring welding quality is much higher than that of submerged arc welding, and the quality of high-frequency welded steel pipe is reliable and durable.
