YZJ-6 hydraulic pipe expansion machine

YZJ series rapid tube expansion machine is a special expansion equipment for boiler and heat exchanger manufacturing and maintenance. The equipment can reliably expand the heat exchange tubes of various specifications and materials, especially for the expansion of thick tube plates and large diameter tube heat exchangers. The heat exchanger produced by rapid tube expansion machine has the advantages of uniform tube expansion, safety and reliability, long service life and low failure rate. Moreover, the expansion operation is simple, the expansion speed is fast, the manufacturing or maintenance time is greatly shortened, the production loss of chemical equipment is reduced, and the economic benefits are very high.

YZJ series hydraulic expansion technology has the following characteristics:

1 High production efficiency.

2 Low labor intensity, easy to operate.

3 The expansion quality is high, and the expansion tightness of each expansion contact is uniform.

4 The expanded device is not easy to stress concentration, and the residual stress is low.

5 The expansion process has no pollution to the pipe mouth, and it can be convenient to use the first expansion and then welding process.

6 The dimensional accuracy of the heat exchange tube is low.

7 The heat exchangers of any tube and plate thickness can be expanded with full thickness.

8 The expansion of the large diameter heat exchange tube can be implemented.
