Regarding the selection of strainers
Thread Content
The inlet temperature of the DN20 pipe is 158, the outlet temperature is 90, and the pressure inside the pipe is around 0.7. I’m wondering whether a PN16 trap will be sufficient for liquid condensate recovery; please give me some advice, experts
Are you asking about the pressure rating? The PN16 can be used. If you’re asking about the discharge capacity, then check the discharge rate of the steam trap.
Selection of a steam trap 1. Pressure level in the pipeline. 2. What is the back pressure when condensate is recovered? 3. What is the displacement?
There is no issue with the pressure rating of the steam trap
The pressure rating is in accordance with HG/T20570.21-1995; the table in the appendix states that the design pressure of the steam trap should be higher than the maximum operating pressure, which in turn must be greater than the design pressure of the steam system.
