TECHNOLOGY OF ELECTROHYDRAULIC PRESS-FITTING OF TUBES INTO TUBE PLATES OF HEAT-EXCHANGE DEVICES
Reliable permanent tubes connection in tube plates of heat-exchange devices.
Influence of the energy released during a high-voltage electric discharge in a water-filled polyethylene membrane on the junction "tube-tube plate ".
3-7 fold increase of corrosion resistance and tube fastening security;
decrease of residual stresses in frontal joint welds and in a weld adjacent zone;
5 fold decrease of tubes thinning;
high performance (10-15 fold higher than by mechanical beading)
no necessity for roller's hard manual operations.
The equipment operates both in an automatic and manual modes remotely controlled by one operator. Pressing quality is governed automatically.
Quality of joints at the diffusion welding level is provided in combination with heat treatment.
At enterprises of the Ukraine and CIS countries.
