The people who produce the welded pipe basically understand the principle that the position of the weld can be changed by adjusting the future of the pipe mould.

Many people in the industry know this, so how to achieve this effect? It is mainly controlled and adjusted by the arc of the pipe mould. The steel strip runs through the arc position of the die. If the mold is adjusted slightly, the operation direction of the steel strip or the pipe after welding is changed, which is to adjust the position of the weld through this function, especially when the square pipe and rectangular pipe are produced, We can see some welding beads at the corner and some on the plane, which is the result of this operation.

For the pipe with the requirement of weld position, the position of the weld can be controlled by adjusting the position of the pipe mould, so that the desired pipe can be obtained.
