In industrial production, overpressure accidents often cause serious consequences such as equipment explosion and media leakage, threatening personnel safety and production order. As an efficient overpressure protection device, bursting disc has the advantages of rapid action, good sealing, and wide application range. It is widely used in chemical, petroleum, pharmaceutical, food, metallurgy, electric power and other fields.
The chemical industry is one of the most widely used fields of bursting disc. In the process of chemical production, reactors, storage tanks, pipelines and other equipment are often in high temperature and high pressure environments, and various flammable, explosive and corrosive media are involved. For example, in the production of synthetic ammonia, methanol and other chemical products, if the chemical reaction is abnormal due to excessive catalyst, temperature out of control, etc., the pressure in the equipment will increase sharply. At this time, the bursting disc can quickly rupture before the pressure reaches a dangerous value, quickly release the high-pressure medium, and avoid vicious accidents such as reactor explosions. For equipment dealing with highly corrosive media, ordinary safety valves can easily fail due to corrosion of the valve core, and bursting disc can be made of anti-corrosion materials, such as hastelloy, titanium alloy, etc., so that it can remain reliable even under harsh working conditions.
The oil and gas industry is also in great demand for bursting disc. In the process of petroleum refining, distillation towers, hydrogenation reactors, heat exchangers and other equipment withstand high temperature and high pressure for a long time, and many of the media are flammable and explosive oil and gas mixtures. If a pipeline blockage, heating system failure or operation error occurs, it is very easy to cause the risk of overpressure. Bursting disc can respond to overpressure conditions in an instant, providing rapid pressure relief protection for the equipment. In natural gas extraction and transportation, equipment such as gas well wellhead installations, collection pipelines, compressor units, etc. need to deal with the impact of high-pressure natural gas. Bursting disc can be used as a safety barrier to prevent pipeline rupture or equipment damage caused by abnormal pressure increase.
High-temperature and high-voltage equipment in the metallurgical and electric power industries also needs bursting disc to ensure safety. In the metallurgical industry, equipment such as steelmaking converters, rolling hydraulic systems, waste heat boilers, etc. are often under high temperature and high pressure conditions, and the medium may include high-temperature flue gas, hydraulic oil, etc. In this scenario, bursting disc can adapt to high temperature environments and quickly release pressure when the equipment is overpressure to prevent the equipment from being damaged due to overload. For boilers, steam turbines, condensers and other equipment in the electric power industry with high operating pressure and high medium temperature, bursting disc can be used as a supplementary protection device for safety valves. When the safety valve fails due to fouling, jamming, etc., it assumes the responsibility for overpressure relief and avoids serious accidents such as boiler explosions.
In short, bursting disc relies on the advantages of rapid movement, good sealing, and adaptability to a variety of harsh working conditions. It plays an important role in safety and security in the fields of chemical industry, petroleum, metallurgy, electric power, etc., and can provide accurate and reliable overpressure protection for all kinds of pressure-bearing equipment, effectively prevent the occurrence of overpressure accidents.
