Hot Tapping & Line Stop Case Studies
The BISEP® has been deployed extensively across the Middle East, and is the world’s first hot tap installed leak-tight double block and bleed isolation of high pressure liquid CO2 pipelines.

Line Stop Technology
Product Information
BISEP Line Stopping
BISEP® offers significant safety advantages over traditional line stop technologies, with the hydraulically activated dual seals providing leak-tight isolation of live, pressurized pipelines.
Applications
- Pipeline launcher valve installation / replacement
- Pipeline repair, replacement, or decommissioning
- Pipeline / pipework re-routing
- Mid-line repair of pipeline defects
- Isolating pressure vessels
- Isolation of pipeline end manifolds, pipeline end terminals for repair, upgrade, or replacement
Multiple BISEPs® can be used to provide mid-line isolation of pipeline sections, and the introduction of a bypass line allows sectional isolation to take place without the need to shut down your entire system – or affect product flow.
The BISEP® is designed to resist backpressure and therefore can also be used as a test boundary for pipeline reinstatement testing.
Uniquely the BISEP® is designed to take 50% of its design pressure in the reverse direction. This allows pressure higher than the isolated pipeline pressure to be applied to the reinstated pipework (as a pressure test or purge) prior to removing the BISEP®.
STATS also supply split tee fittings or mechanical tie-in clamps for hot tap and line stop applications along with its patented dual seal slab valves and SureTap hot tap machines.
To allow the BISEP® and valve to be recovered a completion plug and blind flange can be provided to isolate the fitting branch off-take.

Product Information
BISEP with Integrated Bypass
BISEP® can be configured with an integrated bypass through the launcher, ideally suited to lower pressure applications.
Additional Benefits
- The BISEP® launcher (housing) includes an integrated bypass which maintains production once the isolation is activated, resulting in no loss of production.
- Double block and bleed isolation through a single fitting with integrated bypass requires fewer fittings and significantly reduces costs and project timescales.
- Pipeline pressure maintains a fail-safe isolation independent of hydraulic activation.
- The BISEP® is installed into the pipeline unset allowing deployment into a flowing pipeline, resulting in no interruption to production and saving time on site.
