Imagine the mess a leaking sewage pipeline will create if it is left unattended for weeks at end! In thickly packed urban areas in the UK where sewage lines from every single household converges into one large sewage pipeline, maintenance workers cannot risk such disasters to happen. Preemptive measures are taken in order to mitigate disaster situations. You might have seen maintenance workers going working on pipelines and wondered what actually went on behind the scenes. Well, here is a glimpse into what happens when maintenance workers carry out what they call Pipeline Tapping.
Putting a cork on the pressure
Actually, the very first thing that happens in pipeline tapping is cutting a hole through the hard shell of the pipeline. This allows for tools to be inserted through the hole that helps in controlling the pressure within. What this does it makes it quite possible to manipulate the pressure acting along the pipeline, letting workers plan out their work better without causing any disruptions.
One continuous process
Everything in pipeline tapping is one single process that begins with the pilot bit cutting through the pipe shell and ends with the removal of the coupon (section of the pipe that is cut and removed). When the cutter has done its job, subsequent phases of the process is carried out. Adding new pipelines or removing a redundant section can be easily done with pipe tapping. So effective are the methods of Pipeline Isolation that it can be safely and effectively used for pipes that are on the surface as well as those that are under water.
