HG377 High Frequency Welding ERW Steel Tube Mill,

different in nature

1. High-frequency welded steel pipe: After the hot-rolled coil is formed by the forming machine, the skin effect and proximity effect of high-frequency current are used to heat and melt the edge of the tube blank, and pressure welding is carried out under the action of the extrusion roller to realize production The product.

2. Straight seam welded steel pipe: including double-sided submerged arc welded straight seam welded steel pipe and high frequency resistance welded steel pipe. , JCOE steel pipe, etc.

Two, different materials

1. High-frequency welded steel pipe: The high-frequency resistance welded steel pipe is different from the welding process of ordinary welded pipes. The weld seam is formed by melting the base material of the steel strip body, and its mechanical strength is better than that of ordinary welded pipes.

2. Straight seam welded steel pipe: The materials of straight seam welded steel pipe mainly include pipeline steel series such as Q195, Q215, Q345 and x42. There are two types of straight seam welded steel pipes: ordinary steel pipes and thickened steel pipes according to the specified wall thickness.

Three, different characteristics

1. High-frequency welded steel pipe: smooth appearance, high precision, low cost and small weld reinforcement, which is beneficial to the coating of 3PE anti-corrosion coating. The welding method of high frequency welded steel pipe and submerged arc welded pipe is significantly different. Since welding is completed instantaneously at high speed, the difficulty of ensuring welding quality is much higher than that of submerged arc welding.

2. Straight seam welded steel pipe: The length of straight seam welded steel pipe is mainly divided into fixed length and indefinite length, which are mainly based on customer requirements. The length is generally 6-14 meters. Large diameter straight seam welded steel pipe may need two steel plates Coiling this also creates a double weld.
