Rupture Disc Manufacturer & Supplier

A rupture disc, also known as a bursting disc, is a pressure relief device used to protect equipment and personnel from the consequences of overpressure or vacuum conditions. It is designed to burst or rupture at a specific pressure, allowing the pressurized fluid or gas to escape from the system and relieving the pressure.

Rupture discs are typically made of metal, plastic or graphite, and can be installed in a variety of applications, including pipelines, pressure vessels, tanks, and other pressure-containing equipment. They can be designed to operate in a variety of environments, such as high or low temperatures, corrosive or abrasive fluids, and hazardous or explosive atmospheres.

One of the advantages of using rupture discs over other pressure relief devices such as relief valves is that they have no moving parts and do not require any external power source. This makes them reliable and easy to maintain. Rupture discs are also used in combination with relief valves for added safety and redundancy.

Uses Of Repture Disc

Rupture discs are used in a variety of applications where pressure relief is necessary to protect equipment and personnel from overpressure or vacuum conditions. Some of the common uses of rupture discs include:

  •   Pressure vessels: Rupture discs are often installed in pressure vessels, such as boilers, to prevent them from overpressurizing and potentially causing explosions.
  •   Pipelines: Rupture discs can be used in pipelines to protect against overpressure caused by blockages, pump failures, or other events.
  •   Chemical and petrochemical processes: Rupture discs are used in chemical and petrochemical processes to protect against overpressure caused by reactions, equipment failures, or other events.
  •   Aerospace and aviation: Rupture discs are used in the aerospace and aviation industry to protect against overpressure or vacuum conditions in aircraft fuel tanks, hydraulic systems, and other components.
  •   Pharmaceutical and biotech: Rupture discs can be used in pharmaceutical and biotech processes to protect against overpressure caused by reactions or equipment failures.
  •   Food and beverage: Rupture discs are used in the food and beverage industry to protect against overpressure in tanks and other equipment used in the production process.

Overall, rupture discs are a critical component in pressure relief systems used to ensure the safe and reliable operation of various industrial processes and equipment.

A rupture disc is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from over pressurization or potentially damaging vacuum conditions.

Rupture discs are commonly used in railroad, nuclear, chemical, pharmaceutical, food processing, petrochemical, medical, petrochemical, aerospace, aviation, defense, and oil field applications.

Rupture discs are widely accepted throughout industry and specified in most global pressure equipment design codes (American Society of Mechanical Engineers (ASME), Pressure Equipment Directive (PED), etc.). Rupture discs can be used to specifically protect installations against unacceptably high pressures or can be designed to act as one-time valves or triggering devices to initiate with high reliability and speed a sequence of actions required.

A rupture disc usually is designed to relieve at 1.5 times the maximum allowable working pressure of the vessel. In determining the size of a disc, three important effects must be evaluated: low rupture pressure, elevated temperatures, and corrosion. Manufacturers can supply discs that are guaranteed to burst at ±5% of their rated pressures. The corrosive effects of a system determine the type of material used in a disc. Even a slight amount of corrosion can drastically shorten disc life. Discs are available with plastic linings, or they can be made from pure carbon materials.

A stand-alone rupture disk can be used in preference to a pressure relief valve in the following circumstances:

  •   Reduced capital and maintenance costs: Rupture disks are cheaper than relief valves and do not require as much routine maintenance or pressure testing. After a high-pressure release a rupture disk simply needs to be replaced whereas relief valves need to be reset and tested. (Nevertheless, rupture disks should be checked on a periodic basis for corrosion and metal fatigue. Because the metal in most rupture disks is very thin, even a small amount of corrosion can have a large impact on the item’s performance.)
  •   When loss of the system contents through the vent lines is not important: A rupture disk does not close when the system pressure returns to normal. Hence the entire contents of the system can be lost. If the vented material is of high value, or if the material could cause problems downstream in the vent or flare systems, then a relief valve is the better choice.
  •   Fast response: Rupture disks are extremely fast acting and so should be considered when there is a potential for runaway reactions. In such situations relief valves may not respond quickly enough to prevent a catastrophic failure.
  •   Viscous liquids: If the system is filled with highly viscous liquids such as pre-polymers, a rupture disk should be considered as the relieving device. Flow through a relief valve will be very difficult to calculate accurately. Also, very viscous fluid may not relieve fast enough through a relief valve and may even cause it to plug.
