In industrial production, overpressure protection of pressure equipment is an important part of ensuring safety. Rupture disc, as a cross-disciplinary safety protection tool, takes the reverse arch design as the core, relies on the ring groove to accurately control the burst pressure, and realizes millisecond-level pressure relief through material plastic deformation. There are no mechanical moving parts, strong fatigue resistance and adaptability to a variety of media. It is widely used in petroleum, energy, medicine, food and other industries.
Chemical production involves high temperature, high pressure and corrosive media, and the adaptability of rupture disc can be reflected in this field. At the reaction equipment end, the synthesis reactor and the polymerization reaction tank often cause pressure mutations due to fluctuations in the ratio of reactants and sudden temperature rises. Rupture disc can accurately match the design pressure of the equipment, instantly break the pressure relief, and prevent the kettle body from exploding. For storage tanks with strong corrosive media such as sulfuric acid and nitric acid, the rupture disc can be made of corrosion-resistant materials such as nickel alloy and hastelloy to prevent leakage of toxic media. In the pipeline system, in the face of conveying scenarios containing granular and viscous media, the design without moving parts can avoid clogging. It is installed at the pump outlet and valve node, which can alleviate the local overpressure caused by blockage or misoperation in time and protect the pipeline from breaking.
Catalytic cracking devices in petroleum refining, wellhead pressure equipment in oil and gas extraction, and lithium battery cathode material sintering furnaces in the new energy field all need to cope with extreme working conditions. In the regenerator of the catalytic cracking device, if the carbon deposition of the catalyst causes a sudden increase in pressure in a high temperature and high pressure environment, the rupture disc can withstand long-term high temperature fatigue and break accurately along the ring groove during overpressure. In wellhead oil tree equipment, the impact resistance of rupture disc can cope with pressure pulses during oil and gas extraction and prevent wellhead equipment from being damaged due to overpressure. In the production of lithium batteries, if the inert gas replacement in the cathode material sintering furnace is not completely replaced and the pressure is abnormal, the rupture disc can quickly release the pressure to prevent the furnace body from being damaged and the raw materials from being scrapped, and the debris-free design can prevent impurities from contaminating the product.
The pharmaceutical and food industries have strict requirements for equipment cleanliness. In sterile reaction tanks and vaccine production fermentation tanks in the pharmaceutical industry, the surface of the rupture disc can be polished to prevent the media from remaining and breeding bacteria, and the rupture disc has no debris after blasting and will not contaminate the medicine. For high-temperature sterilizers, rupture disc can withstand temperature fluctuations of repeated sterilization and maintain stable burst pressure for a long time. In juice concentration tanks and dairy sterilization equipment in the food industry, facing the working conditions of acidic juice and high-temperature milk, the rupture disc can be made of stainless steel that meets food-grade standards, which can not only resist medium corrosion, but also quickly relieve pressure during overpressure, prevent equipment damage from affecting food quality, and ensure production safety and product hygiene.
In short, rupture disc relies on the advantages of multi-material adaptation, multi-condition compatibility and high-precision protection, and has become an indispensable safety protection product in industrial production. Whether it is in the high-risk chemical and energy fields, or in the pharmaceutical and food industries with extremely high cleanliness requirements, rupture discs can be customized to meet different needs and protect equipment safety with reliable pressure relief performance.
