In industrial production, pressure vessels, pipelines and other equipment often face the test of complex media such as high-viscosity substances and toxic and harmful gases. Such media can easily cause corrosion and failure of safety devices, blockage and caton, or seal leakage, and become an important hidden danger that causes equipment overpressure explosions, media leakage and other accidents. As an overpressure protection device with the advantages of precise pressure relief, strong weather resistance, and stable structure, composite type rupture disc can effectively cope with the strict requirements of complex media environments. It has become an important tool to ensure the safe operation of equipment in chemical, petroleum, pharmaceutical, energy and other industries.
In the pharmaceutical, food, coating and other industries, high-viscosity media, such as syrups, resins, coating slurries, and easy-to-polymerize media are processed. The medium is prone to slow flow due to high viscosity, or polymerization occurs due to temperature and pressure changes. Attached to the surface of the safety device, it affects the pressure relief performance of the rupture disc. Composite type rupture disc can be adapted to the characteristics of such media. For high-viscosity media, the streamlined design of the slotted part of the composite type rupture disc reduces the flow resistance of the medium, and the elastic deformation characteristics of the positive arch structure can be slightly deformed when the pressure fluctuates, preventing the medium from sticking to the slotted place because of long-term standing. For easy-to-polymerize media, the surface of the rupture disc is polished or PTFE coated to reduce the adhesion of the medium to the surface and prevent the deposition of polymerization products.
In pesticide, fine chemical industry, oil and gas extraction and other industries, toxic and harmful media, such as organophosphorus pesticides, hydrogen sulfide gas, and flammable and explosive media, such as methanol vapor and propane gas, once leaked, it can easily cause poisoning, environmental pollution or explosion accidents. Therefore, the sealing and discharge safety requirements of safety devices are very high. Composite type rupture disc can provide reliable protection for such scenarios. Composite type rupture disc adopts a composite sealing structure, and the sealing surface is precision machined to achieve long-term leakage-free. At the same time, the burst pressure deviation of the positive arch slotted structure is small, which can be quickly released in the early stage of medium overpressure, preventing the continuous increase in pressure from causing an explosion.
In short, no matter what kind of complex media environment it is, composite type rupture disc can break the application limitations of traditional safety devices in complex working conditions through material customization, structural optimization and excellent sealing. Composite type rupture disc can not only resist media corrosion, reduce particle clogging, and prevent material adhesion. It can also minimize the risk of accidents with accurate burst pressure control and rapid discharge response, and provide support for the safe advancement of complex media treatment processes in various industries.
