In the food and pharmaceutical industries, safe production is very important for the development of enterprises. Any abnormality involving pressure equipment may cause production accidents and even threaten product quality. As an important safety pressure relief device, the rupture disc has the characteristics of fast response and reliable sealing. It is an important tool for these two industries to ensure the safety of equipment.
Rupture disc is a disposable safety device, the main function is to achieve rapid pressure relief when the equipment is overpressure. Through preset structural strength and burst pressure parameters, rupture disc, when the internal pressure of the equipment exceeds the safety threshold due to operating errors, uncontrolled material reaction, or equipment failure, the sheet instantly ruptures to form a pressure relief channel, and the high-pressure medium is quickly discharged to prevent the equipment from exploding due to overpressure, deformation and other serious consequences. Compared with safety valves, the advantage of rupture disc is that it has an extremely fast response speed, can cope with sharply increased pressure conditions, and is completely sealed during normal operation without the risk of media leakage. It is especially suitable for the strict requirements of cleanliness and sealing in the food and pharmaceutical industries. In addition, the rupture disc does not need a complex mechanical transmission structure, and can adapt to special media environments such as high temperature, high viscosity, and strong corrosion, making up for the shortcomings of the safety valve under extreme operating conditions.
The food and pharmaceutical industries also have special requirements for rupture disc. Because food and medicines will directly enter the human body, the part of the rupture disc in contact with the medium must meet the food-grade and pharmaceutical-grade hygiene requirements. Materials should also be made of non-toxic and non-precipitating materials, such as 316L stainless steel, hastelloy, etc., to prevent metal ions, coating shedding and other contaminated products. At the same time, the surface should be polished, passivated and other treatments to reduce the growth of microorganisms and material residues. Because the production process of these two industries often involves acid-base solutions, organic solvents and other corrosive media, such as vinegar and juice in food processing, chemical reagents in pharmaceuticals, etc. Rupture disc needs to have excellent corrosion resistance. Through the selection of corrosion-resistant alloys, PTFE coatings or composite materials, the rupture disc will not be eroded by the medium during long-term use, and the structural integrity and blasting accuracy will be maintained. Moreover, food and pharmaceutical equipment have strict pressure control requirements. Too high pressure may destroy product ingredients, and too low will affect production efficiency. The actual burst pressure of the rupture disc needs to be highly consistent with the design value, and the deviation is usually controlled within ±5%. It can act in time during overpressure, neither triggering in advance to affect production, nor delaying the action to cause danger.
Although the rupture disc is a small device, it plays a very important role in the safe production of the food and pharmaceutical industries. Rupture disk can ensure equipment safety, product quality and personnel health through precise pressure relief protection. At present, the industry's safety standards for rupture discs are constantly improving, and our rupture disc technology is also continuing to develop.
