Plate heat exchanger plate quality technical requirements

11-10-2021

The plate heat exchanger has been widely used in industry at present, and it is an efficient and compact heat exchange equipment. Its development has a history of more than one hundred years. After extensive use and practice, everyone has deepened the understanding of the superiority of plate heat exchangers. With the expansion of the field of use and the advancement of production skills, the development of plate heat exchangers has been accelerated, and it has become a very important heat exchange equipment.

The quality standard of the heat exchanger plates also affects the use of this plate heat exchanger

1. The forming and thinning of heat exchanger plates should not be more than 30% of the original actual plate thickness.

2. The parallelism of the base plane in any direction of the heat exchanger plates is not more than 3/1000mm.

3. The deviation of the corrugation depth on the heat exchanger plates should not be greater than 0.20mm, and the deviation of the gasket groove depth should not be greater than 0.20mm.

4. For heat exchanger plates used in the food industry, the roughness of the working surface after stamping should not be lower than that of the original plate.

5. The surface of the heat exchanger plate is not allowed to exceed the thickness tolerance of pits, scratches, indentations and other defects, and the punching burrs must be removed.
