Must safety valves be installed on boilers, pressure vessels, and pressure pipelines?
Yes, according to **relevant laws and regulations**, safety valves must be installed on equipment such as boilers, pressure vessels, and pressure pipelines. This is because in industrial production, if the pressure inside these devices exceeds the designed pressure, it can lead to serious accidents or even casualties. The function of a safety valve is to open automatically under such conditions to release pressure and protect both the equipment and the people involved. Therefore, selection, installation, and maintenance must be carried out in accordance with standard requirements to ensure the proper operation of the safety valve. .
If the source of pressure is not generated by the equipment, a safety valve does not need to be installed on the equipment; it can be installed in the system piping nearby the equipment to protect it.
It should be installed according to the as-built drawings; from a system standpoint, it’s necessary to install it. However, from the perspective of the equipment alone, it may not be required.
When a risk of overpressure exists, overpressure relief devices such as safety valves should be installed.
With a whole system in place, several safety valves definitely need to be installed
