Guangdong Hangao Technology Co., Ltd.

The internal rolling device is composed of a hydraulic system and a rolling trolley. The rolling trolley has two rollers up and down and a mandrel placed in the tube to do reciprocating motion, and the whole system is controlled by PLC program. The inner weld of the stainless steel pipe after welding is smoothed, and the innovative two-cylinder technology in the industry is used to ensure the smooth operation of the trolley, and the trolley reversing adopts dynamic curve setting and touch screen control. Based on the double-push weld leveling function, a high-speed leveling machine has been developed, which is faster and more efficient.
