New Step by Step Map For hot tapping

The BISEP™ provides sizeable security advantages about conventional line prevent technological innovation, the hydraulically activated dual seals provide leak-restricted isolation of live, pressurised pipelines.

Twin compression elastomer seals are hugely efficient even in pipelines with corrosion and ovality difficulties

It should be observed that very hot tapping of sour gasoline traces provides Specific wellness and metallurgical fears and shall be done only to prepared functioning organization approved options.

For every hottap shall be ensured that the pipe that is definitely drilled or sawed has enough wall thickness, which can be calculated with ultrasonic thickness gauges. The present pipe wall thickness (actual) really should be no less than equal to your necessary thickness for pressure as well as an affordable thickness allowance for welding.

Annulus bleed in between seals makes it possible for pressure for being vented to ambient making a zero-Strength zone supplying genuine double block and bleed isolation
