Plate heat exchanger safety valve installation
Thread Content
There is currently a plate heat exchanger used to heat waste liquid through steam; both the steam and the waste liquid are at a pressure of 0.4 MPa. How should the safety valve be configured? Since plate exchangers are used less frequently, is it necessary to install a safety valve on the pipeline on the waste liquid side? Please give me some advice. Should a voltage transformer be installed at the inlet and outlet of the plate heat exchanger as well?
Generally, safety valves are less commonly installed at the inlet and outlet of heat exchangers; relatively speaking, they are more often installed at the top of towers, pipelines, and containers!
The principles for setting the pressure of safety valves require that the set pressure be 1.04 or 1.06 times the operating pressure, with the safety valve settings being 0.416 or 0.424 Mpa.
I’m wondering whether such questions should be asked by the designer or known by the operator :)
