This equipment has a reasonable mechanism, reliable performance and high production efficiency. It adopts a frame-type tension beam structure, and a bottom translation chain type feeding and discharging mechanism.

Large gap seal type (high pressure) or face seal type (low pressure), oil-water booster-type water circuit design, double V-shaped centering clamping mechanism, double

Moving head design, quick change gate design, Siemens and configuration control. The height of the pressure test center is high, and there is no hidden danger to people. Relative to the top

Feeding and discharging method, the bottom translation chain type feeding and discharging type hydraulic press runs smoothly with low noise.

Manufacturers using this type of hydraulic press include: Russia's TMK (Yekaterina plant), Jiangsu Sujia Group host, Hubei Xinye Steel Special Steel Pipe Co., Ltd., Hebei Changfeng Group, Jiangyin Changjiang Petroleum Special Pipe Manufacturing Co., Ltd., Xi'an Zhongshun Automation Welding Technology Co., Ltd. As shown in Figure 1.

Note:

① Design according to the user's requirements for the diameter of the test tube;

② Design a technical solution according to user requirements. The minimum length of the tested tube is 5000mm and the longest can be up to 15000mm.

③ The working cycle is related to the diameter of the tube being tested. The small tube diameter requires less time and the large tube diameter takes longer.
