In the safety production system of many industrial fields such as chemical industry, petroleum, gas, etc., pressure has always been a parameter that needs to be accurately controlled. When the pressure in the system exceeds the normal working range, it will not only affect production efficiency, but may also cause serious safety accidents such as equipment damage, material leakage and even explosion. As an important device for pressure safety protection of industrial equipment, rupture disc can affect the stable operation of the entire production system. So, will the pressure cause the rupture disc to break? How does pressure cause the rupture disc to break? In this article, let me answer for you and tell you how to choose the appropriate rupture disc to ensure production safety.
Rupture disc is essentially a fracture-type safety pressure relief device. The main working mechanism of the device is based on the interaction between pressure and material mechanical properties. When the internal pressure of industrial equipment gradually increases and exceeds the pre-set burst pressure of the rupture disc, the rupture disc will quickly rupture, releasing the excessive pressure in the system, thereby protecting the safety of the main body of the equipment and the surrounding environment. Under the continuous action of pressure, the stress on the rupture disc material continues to increase. When the stress reaches the ultimate strength of the material, the rupture disc will break along the preset structure. This kind of rupture process is usually completed in an instant, and the pressure relief channel can be opened in a very short time. Compared with pressure relief devices such as safety valves, rupture disc has the advantages of faster response, better sealing, and not affected by the characteristics of the medium. It is suitable for some working conditions with high sealing requirements or complex media characteristics.
However, not all pressure changes will cause rupture disc to rupture. The rupture characteristics of rupture disc are highly dependent on the matching of design parameters and actual operating conditions. The design of rupture disc involves multiple angles such as material selection, structural form, and burst pressure setting. Any deviation in any link may cause rupture disc to fail to work normally under the expected pressure. For example, if the burst pressure is set too high, it may cause the system pressure to exceed the tolerance of the equipment, but the rupture disc does not break in time. Conversely, setting too low may also cause malfunction due to normal fluctuating pressure, affecting production continuity. Therefore, the precise customized design of rupture disc is very important to ensure industrial safety.
