FJZJ-280-A High pressure hydraulic pipe expander

Introduction of high pressure hydraulic pipe expander

Summarize：

High pressure hydraulic tube expansion machine is the second generation of hydraulic tube expansion machine developed by our company. The high pressure hydraulic tube expansion machine is mainly composed of hydraulic system, high pressure cylinder, high pressure hose, expansion gun, expansion rod, control box and other components. Especially in the deep hole expansion joint, it can be accurately positioned, and can also meet the different materials and different specifications of the pipe hole expansion joint. The expansion gun is light, easy to operate, suitable for single operation. After expansion, the pipe hole has no pollution, no residue, uniform expansion, and it also has the function of debugable forced pressure relief when the pipe hole is too small and the expansion rod is worn and difficult to pull out. In the production process to reduce losses, improve the comprehensive economic benefits.

Technical characteristics：

1. The 15-500mm thickness tube plate can be uniformly expanded at one time with full thickness;

2. Digital automatic control, expansion pressure can be accurately set, simple operation, reliable expansion quality;

3. Hydraulic system integrated design, the system does not leak oil;

4. Can be internally threaded pipe or seam welded pipe expansion;

5. The residual stress of the expanded heat exchange tube is low, which effectively prevents the gap corrosion and is not easy to be subjected to stress corrosion.

6. After the expansion of the heat exchanger, the axial direction does not stretch and slightly shrinks, reducing the noise of equipment operation;

7. The dimensional accuracy of the heat exchange tube is low, the error of the inner hole of the tube is large, and the diameter of the expansion rod can be adjusted appropriately on site.

8. No pollution at the expansion joint, the first expansion after welding is not affected;

9. Can expand copper, carbon steel, stainless steel, duplex steel, titanium alloy, composite materials, etc.

10. The operation handle weighs only 1.5kg, and one person can expand continuously and quickly;

11. High pressure imported rubber expansion bag has strong fatigue resistance, and the average service life is more than 100 times/branch;

12. Integrated design of vulnerable parts - expansion rod, easy to replace;

13. Low labor intensity, high production efficiency, each equipment can expand more than 2000 pipe holes per shift.
