The application of horizontal push-pull tube expander provides great convenience for tube expansion. It is mainly used for the expansion and tight connection of tubes and tubesheets in the manufacturing of heat exchangers, condensers, high-pressure heaters, etc., which can significantly improve the manufacturing quality of the equipment.
It is a special equipment for heat exchange manufacturing in boilers and large chemical plants. It can be used to expand tubes of various specifications, materials and forms, especially for thick tube sheet and large diameter pipe.
Its characteristics are as follows:
1. High production efficiency.
2. Labor intensity is low.
3. After expansion, the heat exchanger is free from stress corrosion and has low residual stress.
4. The expansion joint has no pollution to the pipe mouth, which makes it convenient for the paper to come from the process of expanding the pipe before welding.
5. The thickness of any tubesheet is expanded with full thickness.
6. The requirements for the dimensional accuracy of heat exchange tubes are relatively low
7. The expansion joint quality is high, and the expansion pressure of each joint is uniform.
