How to replace plate heat exchanger gaskets

  The plate heat exchanger is mainly composed of a frame and a plate. Gaskets are a key component of plate heat exchangers. The working How to replace plate heat exchanger gasketstemperature and working pressure of the plate heat exchanger are restricted by the rubber pad. The rubber replacement of plate heat exchangers also requires technology. The main steps of gasket replacement are as follows:

(1) Remove the aging seals on the plate heat exchanger. According to different dirt, the acid-alkali cleaning tank is used for chemical cleaning. The surface of the parts to be cleaned is not corroded by chemical media (such as gasoline).

(2) Inspect the bonding position and bonding quality of each heat exchanger plate. Sort the accessories according to the drawing installation sequence. Then carefully assemble the plate group.

(3) Inspect the bonding position and bonding quality of each heat exchanger plate. Sort the accessories according to the drawing installation sequence. Then carefully assemble the plate group.

(4) Inspection and testing of recyclability. Check the wall thickness of heat exchangers and pipes in case of suspected corrosion.

(5) After the chemical cleaning of the plate heat exchanger, the chemical medium remaining on the surface of the plate heat exchanger is thoroughly removed by a high pressure purging device.

(6) For bonded gaskets, the residual materials should be thoroughly removed. Re-bonding with a blending adhesive. The recombined heat exchanger sheets are clamped in a special fixture. Heating in an oven to bond Agent curing.
