Pipe welding machine

The pipe rolling machine is a new welding technology, which adopts the principle of rolling forming, rolling the raw materials in the plate into pipes, and then rolling into welds.

The equipment is used for the production of round tubes of strip steel, using an unclosed tube blank, which is then welded into a tube, heated at the edge by a solid-state high-frequency welder, and longitudinal-seam welding in a roll. Pipe welding machines, cooling, further sizing or forming, and continuous cutting of continuous tubes to measured lengths. The finished product will be a round, square, or rectangular tube.

How to use roll forming process in steel pipe production line?

Roll forming refers to the process of forming metal coils or sheets into parts as the material moves through the machine through the continuous rolling of the roller. There are vertical and horizontal rolls for steel pipe production, which are located at the top and bottom of the machine. As the machine moves, driven by electricity and rollers, the shape of the material changes bit by bit until it becomes a circular pipe shape.
We call it cold roll forming because all rolled parts are formed at room temperature, which is a cold forming process. Roll forming can be adapted to a wide range of metals, and here our machines only list carbon steel, steel and stainless steel.
