Packaging and Container Shipping

The production process of high-frequency welded pipes mainly depends on the variety of products. From raw materials to finished products, a series of processes are required. To complete these processes, various mechanical equipment and welding, electrical control, and testing devices are required. The process requires a variety of reasonable arrangements.

The typical production process of high-frequency welded pipe is as follows:

Uncoiling - strip leveling - head and tail shearing - strip butt welding - looper storage - forming - welding - deburring - sizing - UT test - flying cutting - initial inspection - steel pipe straightening - pipe ends processing - hydraulic test - NDT - marking and coating - Finished products.

High-frequency welding is a type of welding method that uses the resistance heat generated by the high-frequency current flowing through the continuous contact surface of the workpiece and applies the upsetting force to connect the workpiece metals to each other. It is similar to ordinary resistance welding, but there are many important differences.

High frequency welding has been used in the production of carbon steel welded pipes for more than 40 years. High-frequency welding has a large power supply and can achieve a high welding speed for steel pipes of different materials, diameters, and wall thicknesses (more than 10 times higher than the maximum welding speed of argon arc welding).

Advantages

HFW steel line pipes are made from long strips of steel of certain specifications, which are rolled into round tubes and welded in straight seams with high-frequency welding machines. HFW carbon steel pipe has the characteristics of fast and continuous production and is widely used in civil construction, the petrochemical industry, the light industry, and other sectors.

It is mainly used for the transport of low-pressure fluids or for the manufacture of various engineering components and light industrial products.
