First of all, according to your own situation, choose a certain process temperature and pressure, and consider whether to choose a detachable type or a fully welded type.

The plate and shell heat exchanger is a heat exchanger with a plate tube as the heat transfer element, also known as a sheet heat exchanger.

During the production process, due to water erosion, cavitation and corrosion of trace chemical media on the heat exchanger tube sheet, leakage often occurs at the weld seam of the tube sheet,

Plate and frame welded heat exchanger, its main heat exchange component is heat exchange plate, which is composed of a series of uniformly pressed and regular metal plates according to the working condition data.

Due to its high heat transfer coefficient, small pressure loss, compact structure, convenient maintenance and many other advantages, the application of plate heat exchanger has been paid more and more attention by people.

In order to avoid the retention of residual liquid and deposits, double-sided butt welding and continuous welding should be used as far as possible during welding, and lap welding and spot welding should be avoided.

The semi-welded plate heat exchanger is a kind of plate heat exchanger that uses two plates along the sealing groove to be welded into plates by laser welding,

The structure of the semi-welded plate heat exchanger is that every two corrugated plates are welded together, and then they are combined together and sealed with gaskets between each other.

Semi-welded plate heat exchangers have refrigerant flowing in welded channels and the only gaskets in contact with the refrigerant are the two circular gaskets between the pair of welded plates.
