YZJ-5 450MPA Hydraulic pipe expander machine

YZJ-5 series hydraulic 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.

 Characteristics:

1, The full thickness of any thickness of the tube plate uniform expansion.

2, Expansion of intermediate tubesheet or multi-tubesheet heat exchangers at any depth.

3, Expansion of internal threaded pipe or seam welded pipe.

4, Expansion after the residual stress is low, not easy to produce gap corrosion.

5, After the expansion of the heat exchange tube, the axial direction is not extended and slightly contracted, which is conducive to reducing the operating noise.

6, The error of the inner hole of the pipe is large, and the diameter of the expansion head can be adjusted appropriately on site (the maximum grinding allowance of the expansion head is 0.3mm).

7, No oil pollution at the expansion joint, the first expansion after welding is not affected.

8, The edge of the heat exchanger with the tube box can be directly expanded, which is very convenient.

9, One person can continuously expand, can expand 6-8 tube heads per minute.

10, The comprehensive economic benefits have been greatly improved.
