Technology of electrohydraulic pressing of pipes in tube grids of heat exchangers
Technology provides
Reliable, permanent connection of pipes in tube grids of heat exchangers.
The essence of technology
It consists in the action of energy released during a high-voltage electrical discharge in a polyethylene shell filled with water on the "pipe-pipe grid" connection.
Advantages of technology
- Increase in corrosion resistance and reliability of pipe fastening by 3–7 times
- Reduction of residual stresses in end welds and the surrounding area
- Reducing pipe thinning by 5 times
- High productivity (10–15 times higher than mechanical flaring)
- Elimination of heavy manual operations of the rolling mill
Technology efficiency
- The equipment works in both automatic and manual modes, is remotely controlled by one operator. The quality of pressing is controlled automatically
- In combination with heat treatment, the quality of the connection at the level of diffusion welding is achieved.
Implementation
At enterprises in Ukraine and the CIS countries.
