SENTRY Gasket

The KLINGER SENTRY is a specialist gasket designed to allow individual flanged joints to be leak tested before a pipeline is pressurised.

 

By testing each connection independently, SENTRY helps reduce testing time, minimise plant downtime and verify joint integrity during installation.

 

How Does SENTRY Work?

 

Traditional pipeline leak testing often requires large sections of pipework to be pressurised, even when only a single flange connection needs checking. This can be time-consuming, require significant volumes of testing media and result in unnecessary production downtime.

 

The KLINGER SENTRY overcomes these challenges by allowing individual gasketed connections to be tested independently. Pressurised fluid is introduced through an integrated test connection, creating pressure within the sealed cavities around the gasket. Pressure is then monitored externally to establish whether the joint is maintaining an effective seal.

 

Both the primary and secondary sides of the seal can be tested, allowing potential leakage paths to be identified before the pipeline is brought into service. If leakage is detected, the joint can be adjusted and retested without the need to revisit it at a later stage.

 

Key Benefits of KLINGER SENTRY

 

• Individual joint testing: Leak test individual flanged connections without pressurising the entire pipeline.

• Reduced downtime: Speeds up leakage testing, helping minimise disruption to plant operations.

• Lower testing media requirements: Significantly reduces the volume of pressurised fluid required.

• Verified joint integrity: Confirms sealing performance during installation, reducing the need for repeat visits.

• On-site adjustments: Allows joints to be tested, adjusted and retested in a single visit.

• Dual seal testing: Enables both primary and secondary sealing areas to be tested.

 

SENTRY Gasket Configurations

 

KLINGER SENTRY is available in two gasket configurations to suit different flange arrangements and application requirements.

 

SENTRY RTJ Gasket

 

Designed for use with Ring Type Joint (RTJ) flanges, the SENTRY RTJ is a heavy-duty metallic gasket suitable for high-pressure applications, particularly in offshore and petrochemical environments.

 

Manufactured to suit the relevant flange standards, including API 6A and ASME B16.20, the metallic ring can be supplied in a range of materials to accommodate different operating conditions and process requirements.

 

SENTRY Maxiprofile

 

The SENTRY Maxiprofile is designed for raised face flanges and is based on KLINGER’s Maxiprofile composite gasket technology.

 

It features a serrated metallic core with a soft facing material. The concentric serrations create localised high-pressure areas, helping the facing material conform to flange surface imperfections and establish an effective seal, even at relatively low bolt loads.

 

A choice of facing and core materials is available, including graphite, PTFE and mica, allowing the gasket to be specified for different chemical and temperature requirements.
