Is a pressure relief device necessary for a pressure-resistant reactor at 0.3 MPa?
Thread Content
A modified reactor that was previously used for production at atmospheric pressure is now being used for production under pressure. Does such a low-pressure reactor need to be equipped with a pressure relief device? What type of pressure relief device? Thank you!
It should be configured; depending on the properties of the material, safety valves or rupture discs can be used accordingly
First, it is necessary to understand 1. the relevant parameters of your atmospheric pressure reactors at the time of leaving the factory； What is the design pressure? ； If it’s higher than the current work pressure ； Then it can be changed ； If it is below the theoretical value, it cannot be changed ； 2. If the conditions can be changed, then a safety valve or a release device of the blast-proof diaphragm type needs to be installed ； However, it must be ensured that the operating pressure of the safety valve or the burst pressure of the explosion-proof disc is lower than the design pressure of the reactor ； Otherwise, the aforementioned release device may not function ；
It must be set. First, it is necessary to determine whether a normal-pressure reactor can be replaced with a positive-pressure reactor, based on the original design and manufacturing parameters. At the same time, the equipment register must have the intended use of the equipment changed, and this change must be reported to the relevant departments.
It is necessary; the type depends on the material. This kettle should also be inspected; after all, it was not used under pressure in the past, so it’s possible that certain defects have developed over time due to prolonged use.
