The CLEAN-SWEEP Rupture Disc Assembly provides
overpressure relief protection for viscous media processes,
particularly where product build-up in a piping system may cause
excessive overpressure conditions.
For many years, pipe tees were used in process lines with the rupture disc assembly
installed off the leg of the tee. However, viscous product build-up could affect the
proper operation and accuracy of the rupture disc.
The CLEAN-SWEEP Assembly is designed to eliminate the
dead space of a pipe tee assembly, as well as the pressure,
temperature and material availability limitations caused by
older, diaphragm valve body-based designs.
The CLEAN-SWEEP Rupture Disc Assembly permits the
rupture disc to be installed directly on the body casting,
adjacent to the process flow. Compared to other designs,
it requires fewer joints to be sealed and greatly reduces
the possibility of product build-up (dead space) under the
rupture disc.
Designed for operating pressures up to 1440 psig (99,3 barg), the CLEAN-SWEEP
Assembly is custom machined to bolting classes of ANSI, DIN, JIS or as specified by the
customer. Alignment pins in the assembly inlet provide correct rupture disc orientation
during installation. Once installed, the 3-Dimensional Flow Direction Tag, which is
permanently attached to the rupture disc, is a visual reference that the rupture disc will
discharge in the intended flow direction.
The CLEAN-SWEEP Assembly body is available in standard materials of 316 Stainless
Steel, MONEL®, or HASTELLOY C®. The rupture disc holder outlet and outlet companion
flange are available in materials of Carbon Steel, MONEL®, INCONEL®, Nickel, 316
Stainless Steel or HASTELLOY C®.
A permanently attached nameplate with flow direction indication is supplied on the
CLEAN-SWEEP assembly. Whenever specific identification tagging is required, a
stainless steel customer identification tag is permanently attached at no extra charge.
