What is the proportion of pressure drop in the selection of plate heat exchanger?

We all know that the plate heat exchanger has undergone a series of strict data testing from selection design, raw material procurement, production and final to factory. Especially in the last process, it must be delivered to the end user after the strict 1.0MPa hydraulic test is free of leakage. So today, we will understand the proportion of pressure drop in the selection of plate heat exchanger?

First of all, this is an abstract concept, because each manufacturer has different steps for the process. This is not a national standard, generally is enterprise standard. So today, we mainly take our company as an example to solve this problem for you. First, tell you that the pressure drop is the maximum working pressure value in the user working condition. Generally, the customer will provide it. And the import and export temperature, flow rate measured at one time, the inlet and outlet temperature and flow at the secondary side are informed to us. Then we have a selection of plate heat exchanger and design according to the parameters. At this time, generally speaking, our design standard is 50kPa based on our experience in the industry for 12 years. For water or may be low, considering the small temperature difference, the heat transfer coefficient is too high, so our channel number wil become more.

Then, we should also introduce to you here. Some customers directly ask for price with the heat exchange area. Basically, we don't know anything. Generally, we will test the pressure according to the pressure of 1.0MPa. The maximum pressure of water and oil-water industry will not exceed this high.

It can be concluded that the proportion of pressure drop in the selection of plate heat exchanger should be 50% in Efreet, because we will take this factor into full consideration regardless of the link. Finally, it is suggested that if the pressure exceeds 1.2MPa, then the 0.5mm plate will not be used, which will easily cause deformation and leakage.
