What types of containers require safety valves? According to what criteria? Thank you for your guidance, colleague: handshake
There are no standards that stipulate this specifically; the general principle is that safety valves should be installed in situations where the process is unstable and where pressure may change abruptly—this applies particularly to reactors. Heat exchangers are rarely installed.
Containers for holding gases or gas-liquid mixtures are generally designed to be equipped with safety valves.
It generally depends on the process and operating conditions, with primary consideration given to the impact of actual operational fluctuations in the medium
It should be determined based on the process conditions and general production experience. For example, gas tanks, purge air tanks, high-pressure tanks, hydrogen tanks, etc. Our reactors here don’t have control valves installed. If something gets into the flare system from the top of the reactor, there will be high temperatures, hydrogen, as well as oil and gas – it’s unimaginable
In this operation, system fluctuations can pose risks; therefore, safety valves are installed in all such areas. Currently, Hazop analyses are generally carried out, and safety valves are present in every location where there is a risk.
GB/T20801.6-2006 \"Code for pressure pipelines – Industrial pipelines\" Part 6: Safety protection specifies this clearly in Section 4 on safety relief devices
In principle, all pressure vessels must be equipped with safety relief devices. If a piping system is already in place, it may be omitted upon review and approval. For details, see TSG R0004-2009 \"Regulations on Safety Technical Inspection of Fixed Pressure Vessels\"
