Installation of safety valves on steam pipes
Thread Content
The steam main splits into multiple branch pipes leading to the reboilers; the pressure in the main pipe is 0.3 MPaG. Should safety valves be installed on the steam main, or should they be placed at the steam inlet of each individual reboiler? Or should safety valves be installed on both the main pipes and the branch pipes?
Only a safety valve is installed on the main pipe after the cut-off to the device; no separate safety valves are required for each equipment unit that uses steam.
A safety valve should be installed on the main pipe; if the pressure in the branch pipes exceeds the limit, then the pressure in the main pipe must also be too high. So, ensuring that the main pipe is properly equipped will solve the problem
0.3 MPa is considered low-pressure steam; generally, we do not install safety valves on the pipelines, as it is sufficient to have safety valves only on the equipment that generates steam.
The supervisor level is usually sufficient; if the client thinks the cost is too high, it doesn’t matter even if additional settings are used
