Pre-loaded holder

STRIKO standard bursting disc holders in intermediate flange design only reach a fixed and dense clamping of the bursting device after tightening the flange screws. This means that after loosening the flange connection also the metallic seal between the bursting disc and the holder is removed. With STRIKO pre-loaded holders PRO for bursting discs of the series SZ and SU however, the required tightening torque for secure and dense installation of the bursting disc is already applied by the high-strength preloading screws when installing the bursting disc into the holder. Thus it is possible during machine downtime to loosen the flange connection and perform a visual inspection, to clean or even carry out the required replacement of the flange seals without the need to insert a new bursting disc. This shortens downtimes following a reaction of a bursting disc by up to 80%. The use of pre-loaded holders is particularly recommended for sensitive steel-enamel / glass and plastic pipes, polymerisation processes, in case of a tendency towards caking, unfavourable installation positions and frequent replacement of bursting discs.
