What is a torn disk?
Rupture Disc is a mechanism that fails if the pressure in the sealed container overcomes the upper limit, allowing the pressure to fall before other undesirable events occur. These safety valves are used in many applications and use a wide range of needs. They are also known as crackling discs or a membrane rupture. This proposal requirement is based on the justification that the cause of the state of overpressure should be found to maintain safe operations. The connected equipment and surrounding equipment and structures should also be checked before re -use.
Safety device for pressure relief is produced as a system. The correct holder and the correct part must be used. While incorrect components may be physically useful, tolerance, structural strain or other parameters may vary sufficiently and bring unnecessarily low pressure failure, or allow the rpressure to continue.
Important proposal criteria for torn disk include the fact that the disc fails at the specified pressure in the range specified by the manufacturer. The differences in pressure limits are achieved by changing the properties of the material, the shape and size of the disk and the assembly system. Other design criteria may include disk nefragmentation, use for sterile conditions, or biological retention systems that allow the pressure to leak but not any biological materials. The torn disk designed for nuclear environment, such as a nuclear submarine or power plant, is exposed to very strict design requirements. Material properties, especially distortability or easy breaking, may change if the disk is subjected to radiation.
The original torn disc was developed in 1931 by BS & B safety systems. Type B DISC was sold starting from 1934. Since then, a rupture disk of type B has been used in hundreds of thousands of applications. The pressurized side is concave, a disk similar to a bowl. As the pressure loads, the disk experiences the forces onFive, as the material stretches or bulges outwards.
Specialized use of rupture discs includes those designed for tanks in transit, such as train or truck. The movement of the liquid inside the container requires that the cracked disk non -peractive with some of the components in the liquid. Dangerous materials may require a second torn disk that fails with higher pressure to contain the material despite the state of overpressure.
