Hydraulic Tube Expander Machine

Hydraulic tube expander machine is a special expander for boiler and heat exchanger manufacture and maintenance. Hydraulic tube expander machine can expand heat exchanger tubes of various specifications and materials reliably, especially for thick tube sheet and large diameter tube heat exchangers. The heat exchanger produced by expanding technology of rapid expander has the advantages of uniform expansion, safety and reliability, long service life and low failure rate. Moreover, the expansion operation is simple and the expansion speed is fast, which greatly shortens the manufacturing or maintenance time and reduces the shutdown loss of chemical plant, and has high economic benefits.

 

Hydraulic expansion technology has the following characteristics:

1. Expansion of tubesheet with arbitrary thickness at one time.

 

2. Expanding the middle tube-sheet or multi-tube-sheet heat exchangers at any depth.

 

3. Expansion of internal threaded pipe or welded pipe.

 

4. The residual stress after expansion joint is low and the gap corrosion is not easy to occur.

 

5. The expansion joint of heat exchanger tube will not elongate axially but shrink slightly, which will help to reduce the noise of operation.

 

6. The inner hole error of the tube is large, and the diameter of the expanding head can be adjusted appropriately in the field. (The maximum grinding allowance of the expanding head is 0.3mm).

 

7. There is no oil contamination in the expansion joint, and the expansion before welding is not affected.

 

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

 

9. Single person can expand continuously, 6-8 pipe ends can be expanded every minute.

 

  1. Comprehensive economic benefits have been greatly improved.
