1. Inspection and cleaning of heat exchanger plates before reuse:
1. Check the wall thickness of heat exchangers and pipes when rust is suspected;
2. Remove the aged seals, and use acid and alkali for chemical cleaning according to different dirt, and the surface of the cleaned parts will not be corroded by chemical media;
3. After chemical cleaning, use a high-pressure blowing device to thoroughly remove the chemical medium remaining on the surface of the plate heat exchanger and in the pipeline;
4. Coat the heat exchanger plate with fluorescent test agent, check whether there are small cracks and corrosion holes under the irradiation of ultraviolet light, and clean it again.
5. It is also necessary to focus on checking the condition of the sealing groove, and repair it if necessary.
2. Inspection and cleaning before reuse of GEA VT405 Heat Exchanger Rubber Gasket For Milk Pasteurization:
1. Check whether the surface of the gasket is stained with any impurities other than rubber. If there is any, it must be removed, and the gasket must not be damaged in the slightest;
2. Observe whether the gasket has obvious indentation, or the local thickness is obviously thinner than the overall thickness. If any such phenomenon is found, please remove it completely;
3. Compare the gasket with the gasket groove and observe whether the length is shorter than 8mm, or the length is 3mm longer than the gasket groove. If you find any such phenomenon, please remove them all.
4. For the adhesive gasket, the residual substances will be completely removed, and the re-adhesive adhesive will be used to re-bond. In order to achieve the best bonding effect.
