Straight seam high frequency welded steel tube

The straight seam high-frequency welded steel pipe is a kind of steel pipe made by high-frequency welding process, which has the advantages of high production efficiency, low cost and stable quality, and is widely used in various fields. The following is a detailed introduction to the straight seam high frequency welded steel pipe:

Raw material preparation: Select high-quality steel plates or steel strips as raw materials, and after cutting, calibration and other processing, ensure that the size and quality of raw materials meet production requirements.

Molding: Send the prepared raw materials into the molding unit, and process the raw materials into tubes through multiple passes of rolling and bending.

High-frequency welding: Use high-frequency current to generate heat on the welding edge of the steel pipe, so that the welding edges melt and fuse with each other to form a firm weld. High frequency welding has the advantages of fast heating speed, good weld quality and high production efficiency.

Cooling and sizing: After the welding is completed, the steel pipe is cooled to prevent the weld from overheating and causing deformation or cracking. At the same time, the diameter of the steel pipe is precisely determined by the sizing unit to ensure the dimensional accuracy and roundness of the steel pipe.

Straightening and cutting: Straightening the cooled steel pipe to eliminate bending and twisting during welding and forming. Then, the steel pipe is cut according to the customer's requirements to form a length that meets the requirements.
