During the installation process of the plate heat exchanger, the choice of the interface form is also very important. Then in the heat exchanger design process, what are the main interface forms of the plate heat exchanger? 
What are the characteristics? 
Which situation is it mainly used in?

The first type of interface is a plate flat welded flange with a connection pipe. The connection pipe is generally a stainless steel connection pipe, which is welded with the inner liner ring through the corner hole opened in the plate heat exchanger, which can effectively avoid heat exchange. 
The medium is in contact with the frame, and when the width of the heat exchanger is narrow, it takes the form of high and low pipes to effectively and rationally use the space position.

The other is the bushing interface with bolts. This is where the flange corner holes are made of stainless steel or other special materials. The medium does not contact the frame material, and the bolt holes of the connecting flange are directly opened on the frame plate. This is 
The most common form of interface. 
It has the characteristics of simple structure and use.


There is also a loose flange type. The loose flange is familiar with the connecting flange, but the flange is not welded to the connecting pipe, and the flange is movable as a whole. This is generally used for the overall replacement of heat exchangers. 
The size requirements are stricter.


There are also threaded connection ports and quick ports. 
I won't repeat them here.
