Hydraulic pressure tube expanding machine


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.

  • STE-300 series rapid expander is a special expander for boiler and heat exchanger manufacture and maintenance. The equipment can expand heat exchanger tubes of various specifications and materials reliably, especially for thick tube sheet and large diameter tube heat exchangers. 


  • characteristics: 

  • Expansion of tubesheet with arbitrary thickness at one time. 

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

  • Expansion of internal threaded pipe or welded pipe. 

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

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

  • 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). 

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

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

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

  • Comprehensive economic benefits have been greatly improved.

Working principle



Structure of expander

The hydraulic pipe expander is mainly composed of hydraulic control system, pressure amplification system and hydraulic pipe expander control system.


Working principle

Hydraulic pumps are driven by motors to pressurize the hydraulic control system, and the pressurized expanding pipe medium is sent to the operating handle through the high-pressure hose, thus realizing the pressure on the expanding joint. Pressure setting is mainly through touch screen to set the user's required pressure. The pressure of expanding tube medium is transmitted to DAC module through transmitter. The pressure value is displayed on the touch screen "current pressure value". When the current pressure value is equal to the set pressure value, the pressure relief system works and the whole expansion process ends.
