KLINGER Sentry Gaskets
Reverse integrity gaskets
Pressurized systems are tested for various reasons:
Code compliance during fabrication and installation
Service/leak test before commissioning and start-up
Leakage testing on a newly erected or amended pipeline is traditionally carried out by filling the pipeline with pressurized water or gas to monitor any changes in pressure which indicates a defective joint. The process is carried out in sections by blanking off an area of a pipeline using shutoff valves or blinds.
Depending on the valve location, it may be a large section of pipeline that must be pressurized to test a single flange connection and, in some cases, it is not practicable to leak test all of the joints. Leak testing large portions of pipeline is a time consuming process, increasing production downtime and consequently induces economic loss.
The KLINGER Sentry Reverse Integrity Gasket allows leak testing on individual flanged joints without the need to pressurize the full system.
KLINGER Sentry Reverse Integrity Gaskets are designed so leakage testing can be carried out on individual gasketed connections to determine if tightness has been achieved before introducing internal pressure and also allows monitoring of the joint throughout its lifespan.
The Sentry can be used in both ring joint and raised face flanges.
Sentry RTJ gaskets are heavy duty, high-pressure gaskets largely used in offshore petrochemical applications.
The Sentry DS is an IBC dual-seal Maxiprofile composite gasket designed for use in standard raised face flanges.
