Material selection for high-pressure heat exchangers
Thread Content
Working pressure: 25 MPa on the tube side and 25 MPa on the shell side. What material should be used?
To be more specific, in what application is this device intended to be used? It seems to be a shell-and-tube water cooler; does the fluid also need to flow through the shell side?
Today, heat exchangers that operate under high temperature and pressure are mostly made from special stainless steels, which not only reduces corrosion but also decreases the frequency of maintenance, thereby saving costs
The material is related not only to pressure but also to the process medium, pipeline size, corrosivity, gas-liquid phases, temperature, and so on
What medium? What are the operating temperatures? Be more detailed!
Adding to the post. The process medium is water, with a working pressure of 25 MPa, an inlet temperature of 25°C, and an outlet temperature of 550°C. The shell-side fluid is a biomass solution, with a working pressure of 25 MPa, an inlet temperature of 625°C, and an outlet temperature of 75°C. Question: Material selection?
