Problems with pressurizing plate heat exchangers
Thread Content
I have a question regarding this operating condition: it’s a plate heat exchanger with a diameter of DN300, an installed area of 500㎡, and approximately 300 plates. The design pressure is 16 MPa, so the test pressure should be 2.0 accordingly. I would like to ask which manufacturers in China are capable of using adhesive pads with non-stick buckles to achieve a pressure of 2.0 MPa; likewise, what if the pressure cannot be reached at such a high level? Everyone, please help analyze the reasons. My understanding is: First, the deck thickness needs to be increased. Second, whether the number of bolts and their strength need to be increased. Third, could it be that the fit between the gaskets and the plates isn’t optimal?
Mainly from the following aspects: large plate thickness, bolt strength, sealing structure, and addition of intermediate partitions
It seems that everything needs to be treated with gaskets and plates; otherwise, when the pressure increases, the gaskets will come out. I work in the field of heat exchangers, and I’ve worked on 16 units that were press-fitted.
By \"handling it\" as you mentioned, do you mean using glue? Which domestic manufacturers are capable of conducting experiments with 20 kilograms at a 300-caliber scale? If you know anything, please let me know so we can discuss it together. Alpha told Chante that there’s no problem!
