Graphite rupture discs is a pressure relief device designed using the characteristics of graphite materials. It is mainly used in industrial scenarios where overpressure needs to be released quickly. The application of rupture discs is greatly related to the corrosion resistance, high temperature stability and structural characteristics of the material. This article can help you understand the common application scenarios of graphite rupture discs.
Graphite has good chemical resistance, especially to corrosive media such as strong acids, alkalis and organic solvents. In reactors, storage tanks, and piping systems in the chemical industry, when the medium is highly corrosive, metal rupture discs can easily be corroded and fail, but graphite rupture discs can be well adapted to this working environment. For example, equipment such as absorption towers and hydrochloric acid storage tanks in sulfuric acid production can be discharged during overpressure through graphite rupture discs to prevent the risk of failure of the equipment due to corrosion.
Graphite material can maintain structural stability at higher temperatures, and the applicable temperature can reach 200℃. In high-temperature equipment such as petrochemical cracking plants, high-temperature reactors, and waste heat boilers in the energy industry, metal rupture discs may fail due to high-temperature oxidation and decrease in strength, while graphite rupture discs rely on high-temperature resistance characteristics to be discharged in time when the equipment is overpressure.
Graphite rupture discs are suitable for low-pressure or micro-pressure conditions and are widely used in fermentation tanks and vacuum drying equipment in food, pharmaceutical and other industries. The internal pressure of these equipment is low, and the sensitivity of the metal rupture discs is insufficient. The brittleness characteristics of graphite rupture discs can quickly rupture when the low pressure exceeds the limit, achieving the purpose of accurately controlling the discharge pressure and preventing pollution to the sterile environment in the equipment.
The graphite material itself has strong chemical stability and is not easy to react with the medium, and the surface of graphite rupture discs is smooth, easy to clean, and meets the hygiene standards of food, pharmaceutical, bioengineering and other industries. In pharmaceutical reactors and food sterilization equipment, temperature resistant rupture disc can prevent the impact of metal ion precipitation on product purity on the basis of meeting the pressure relief requirements, and can ensure the cleanliness of the production process.
For treatment systems containing highly corrosive gases such as fluorine and chlorine, or pipelines containing granular and viscous media, the wear-resistant and anti-adhesion properties of temperature resistant rupture disc can reduce the damage of the medium to the discharge element, allowing temperature resistant rupture disc to act in time during overpressure and extend the service life of the equipment.
The temperature resistant rupture disc produced by Shenyang Xinguang Aerospace Safety Systems Co., Ltd. can be installed directly between the flanges or used with the bracket, and can be equipped with PTFE/FEP lining to enhance chemical resistance.
