What is a reverse arch with slotted rupture disc?
On the arch or concave surface of the rupture disc, there is a dddhhhcrossdddhhh shaped weakening groove, the convex surface contacts the medium, and the concave surface is on the release side. During blasting, the rupture disc flips to the concave side and breaks along the groove to release pressure.
Features of rupture disc:
1. Applicable to gas and liquid media.
2. Reverse arch with slotted rupture disc is suitable for medium and high pressure conditions.
3. No fragments after blasting, recommended to be used in series with safety valve.
4. No need to add a pressed bracket, it can withstand full vacuum state
5. The working pressure can reach 90% of the allowable blasting pressure.
6. If fluorine coating or polytetrafluoroethylene coating is required, the operating temperature is 260℃.
Reverse arch with slotted rupture disc is widely used, mainly in the following fields:
Chemical industry: reverse arch with slotted rupture disc is used in various chemical reactors. When the reaction is out of control and the pressure rises sharply, it can rupture and release the pressure in time to prevent explosion accidents. It can also be used in equipment such as oil cracking units and distillation towers to protect the safety of equipment and personnel and avoid environmental pollution and economic losses caused by material leakage.
Petroleum industry: In the wellhead device of oil extraction, reverse arch with slotted rupture disc can prevent the damage of equipment by high pressure conditions such as blowout. In the hydrogenation reactor, vacuum distillation tower and other equipment of oil refining, when the pressure rises abnormally, it can quickly release the pressure to ensure the stable operation of the equipment.
Gas storage and transportation field: used in gas storage tanks, such as natural gas storage tanks, hydrogen storage tanks, etc., to prevent explosions caused by overpressure. In the key parts of the gas transmission pipeline, such as the compressor outlet and the branch of the pipeline, when the pressure exceeds the set value, the reverse arch grooved rupture disc ruptures and releases the pressure to protect the safety of the pipeline system.
Power field: In coal-fired boilers, gas turbines and other equipment for thermal power generation, when the pressure is abnormal, timely pressure relief is carried out to prevent equipment damage. In some auxiliary systems of nuclear power plants, such as the safety protection system of steam generators, it can also play an overpressure protection role.
Pharmaceutical and food fields: In reactors and drying equipment in the pharmaceutical industry, reverse arch with slotted rupture disc can relieve pressure without generating fragments to avoid contamination of drugs. In high-pressure sterilization equipment and vacuum drying equipment in food processing, when the pressure is abnormal, safe relief is carried out to ensure food quality and production safety.
