Gas purging / Decommissioning
It's in the name
At purge point we offer a range of purging and decommissioning, whether it's using an inert gas such as nitrogen to clear the lines, or using a high power compressor for clearing larger industrial lines, sometimes flaring is necessary (burning off in a controlled manor) it's important to make sure all the gas is out of the line for demolitions and additional works and extensions. It's important to maintain the correct minimum purge velocity to make sure stratification doesn't occur, it sounds complex but essentially if purge velocity (QP) is wrong it results in non laminar flow (turbulent) of the purge gas where it can ride over the fuel Gas resulting in an incomplete purge. All work is verified by purge calculations and Gasco seeker ( Gas Detector ).
Then a purge certificate given to certify works.
Also if it's a newly installed line we can purge to Gas and also certify the results within upper safe purge limits.
