Burst disc is only normally used when encountering something which has a very very low probability of occurring but high consequence. If this happens any time you come to a sudden halt, burst discs are not the answer. They are probe to accidental rupture, cannot be tested, degrade with age/corrosion and if the break need a shutdown to refit new

Mar 01, 2009 · Rupture disc devices provide overpressure protection for a variety of storage and process vessels and equipment. The objective of the rupture disc is to maintain a leak-tight seal and be a passive bystander until called upon to relieve excess pressure.
Rupture Disks. A rupture disk is designed to rupture at a predetermined pressure and temperature (Figure 2). If designed under ASME Boiler and Pressure Vessel Code, the rupture disks are stamped with the certification mark and one of the certification designators UD or TD.
Because the dangerous potential of boilers is a situation that can be controlled, the National Board has an opportunity to extend its leadership role in the arena of safety. Explosion depends on how the vessel fails, when it fails, and how close people or properties are when the rupture occurs.
A solid-metal, tension-acting rupture disc that screws directly into a threaded port, providing precise overpressure protection with simple installation. Protect equipment, personnel and the environment with the threaded, single-use WMP assembly. The WMP is ideal for applications that discharge to the atmosphere at the rupture disc.
A rupture disk is a thin diaphragm (generally a solid metal disk) designed to rupture (or burst) at a designated pressure It is an engineered “weak spot” designed to protect vessels, piping, personnel, and equipment from unexpected excessive pressure “A rupture disk is to a pressurized system what a fuse is to an electrical system”
Rupture Discs function as a pre-designed “weak point” in a pressurized system, and they should be the strongest part of your pressure protection system. Continental Disc rupture discs utilize innovative, patented designs, the highest quality materials from traceable sources, and ISO 9001 manufacturing procedures performed by skilled craftsmen.
This content provides you a sample rupture disc inspection and test plan. This rupture disc ITP is a draft and must be edited and meet your purchase order specifications.
A rupture disk, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.
The NUK-HP® is a high-pressure natural circulation boiler operating by the gravity circulation principle. Therefore circulating pumps are not required to operate the NUK-HP®. Boiler water is used as the heat carrier. The water is evaporated in this boiler within a hermetically sealed circuit.
Our rupture discs are designed to meet your facility’s pressure protection needs. Below is a comparison chart of the many discs we have to offer. And if you don’t find the disc that meets your needs, connect with a Fike representative to start the conversation on custom engineered solutions for your facility.
A rupture disk device is a non-reclosing pressure relief device that actuates upon differential pressure across the disk. It consists of two main components: the rupture disk holder which provides the pressure boundary and clamps the disk into position, and the rupture disk (the actuating element).
A rupture disc holder with high-strength steel socket head cap screws to ensure accurate loading and sealing of HPX rupture discs. Optimize flow, secure seals, ensure proper disc orientation and prevent disc fragmentation with an HPX-PT pre-torqued holder.
Rupture discs are, as of today, the perfect tools to guarantee complete safety. What is a Rupture Disc? How Does a Burst Disk Work? Rupture discs are safety devices with the function of stopping sudden variations in pressure from damaging an industrial plant.
If a high pressure boiler operates at 100psig, what should the blowback of the safety valve be No more than 4%, and not less than 2psi in any case What is the minimum blowback on a safety valve that pops at 250psi
Oseco's 165 psi SRC or Scored Railcar Disc is an alternative to railcar rupture discs containing PTFE seals. The scored technology used in the all metal SRC eliminates the possibility of leaks caused by the PTFE in composite discs.
In accordance with ASME Boiler and Pressure Vessel Code (Section VIII Division 1), rupture or “burst” disks must break within 2 psi for disks rated to 30 psi and a tolerance of 5% is allowed for disks rated above 40 psi. Rupture disks are also certified by the National Board.
