During the welding process of stainless steel welded pipes, various problems often occur on the inner and outer walls of the pipes due to the process of forming and welding the pipes.

For example, a series of problems such as rough surface of the weld seam, uneven transition of the base material, and high protrusion at the weld joint seriously affect the quality of the welded pipe, which is also a problem that does not meet industry standards.

Therefore, in order to solve the problems caused by welding seams and have more outstanding performance advantages, it is necessary to use a leveling machine to level the welded pipe after welding is completed.

How does the weld leveling machine process stainless steel welded pipe welds online?

It is achieved by controlling the rolling strength and passes to level the internal and external welds of stainless steel welded pipes. By repeatedly rolling the internal and external welds of the welded pipes, the excess height of the internal and external welds will gradually disappear, and the transition between the base materials will become even. The quality of the welded pipes will be improved, ultimately meeting the relevant standards formulated by the country and industry.

The internal weld leveling machine designed and developed by Hangao Institute innovatively adopts PLC+proportional hydraulic control for automatic control on the basis of the original leveling machine.

Compared to previous products, machine installation and debugging have become more convenient, with significantly improved operational stability and welded pipe yield.

As the power system of the shuttle car, the servo motor solves the problems caused by jerks during operation, improves the operating accuracy, and becomes more stable and gentle. The hydraulic rolling maintains the high strength characteristics of the original hydraulic leveling machine, and can be easily rolled and leveled for some pipes with thicker wall thickness.

High work efficiency and good leveling effect perfectly illustrate the functions and advantages of the Hangao leveling machine.

After continuous development and upgrading, the Hangao leveling machine has been recognized by market customers and is one of the necessary production equipment for high-end industrial welded pipes recognized by domestic high-end customers.
