When the used ERW tube mills is used to make welded pipes, the judgement of the qualified quality of the welded pipe depends on the control of the squeeze roller, so the control of the squeeze roller is very important. There are many ways to control the squeeze roll, and "up, two, next" is one of the squeeze roll methods.

The "up two next one" three-roll extrusion method can be said to be the best extrusion method for small pipe diameter welding (steel pipes below 114mm) in the used ERW tube mills. Three-roller independent adjustment, three-roller unified adjustment and overall rotation make the adjustment consistent. The three squeezing rollers each cover nearly 120 degrees, and the diameter and load-bearing capacity of each roller are effectively reduced. Vee length = pipe diameter, which is the most efficient. The upper two rollers effectively fit the edges of the steel strip in an angle form, forming a good squeezing force and controlling the edges of the steel strip. Many disadvantages of the two-roller and the top three-roller are avoided, so it is an ideal welding extrusion device.

 

The disadvantage is that the technical requirements, processing accuracy requirements and cost are relatively high, and adjustments are more difficult at the same time, which limits the promotion. It is usually used on steel pipe lines with higher requirements.

The essence of adjusting the diagonals of the used square pipe mill is to adjust the square of the square tube. In theory, if the two diagonals of the square tube are equal, the square tube is square. But not necessarily for the rectangular tube in physical form.
