Our quality system as well as the design and manufacture of our discs are regularly audited by a notified body which ensures that our products comply with the requirements of this directive.
Effective pressure maintenance
Rupture discs manufactured by Witzenmann are essential pieces of safety equipment used in pressurized or vacuum piping systems.They are designed with precision according to the specific pressure constraint, they break if a combination of pressure & temperature is exceeded. Thus they compensate for pressure peaks avoiding any material damage and bodily injury with great reliability. Witzenmann design and manufacture rupture discs specially tailored to the individual requirements of each project. They can also be integrated later into pre-existing system configurations.
Principle: The operation of the direct discs is based on the breaking strength of the strip material.
Principle: The operation of the reverse discs is based on the resistance to buckling of the strip which is turned and cut on a knife.
