Pressure Relief | CBS Type Rupture Disk

Protective for CBS type intermodal transport tank container with a tension type rupture disk.

The CBS type rupture disk protects intermodal transport tank containers, which have particularly high demands for heat resistance, corrosion resistance, and airtightness in pressure relief devices (rupture disks). It is used additionally below safety valves (e.g., valves manufactured by Fort Vale) to protect the safety valve from corrosion caused by the product and to ensure the airtightness of the safety valve. The operating pressure ratio of the rupture disk is 80% of the minimum burst pressure*, and it can be directly mounted between flanges, opening in a star shape with no fragment dispersion. It is fully compatible with vacuum and overpressure applications and can be used with liquid or gaseous media. The CBS type design has the highest level of airtightness and is mounted with a protective ring located below the outlet gasket. To enhance corrosion resistance, it is also possible to add a lining on top of the inlet gasket if necessary. *This may vary for special applications.

basic information

【Benefits of Use】 ★ Ultra-long lifespan and high heat resistance due to the use of high-quality materials such as tantalum, hastelloy, and inconel ★ Highest level of airtightness with a seal membrane layer (optional) ★ Extension of safety valve lifespan as the safety valve is protected from the transport medium (corrosive) during normal tank operation ★ Capability to accommodate a variety of materials and dimensions that meet process conditions
