Besides our capability and experience in the construction of flowlines/pipelines, our team of seasoned professionals along with our state of the art technology/equipment are able to maintain any size of hazardous and flammable product carrying pipeline without interruption to product flow through the below methods;

Hot tapping

Hot tapping is a process by which a nozzle or hot tap saddle is added to a pressurized pipeline to allow flow into or out of the pipeline, install instruments, sampling probes or to install an inflatable pipe plug.

Line stopping

Line Stopping is EMAG means of isolating a piping system to prevent unwanted shutdowns and keeping critical piping and pipeline systems online during tie-ins, relocations, repairs, retrofits, and routine maintenance. This process serves as a control, or temporary valve, that can be removed after alterations or valve replacements have been made.

EMAG only utilise clamps with WAFFLE GASKET with fine ridges of which mould themselves to cracks and irregularities in the damaged pipe ensuring a reliable and permanent repair.


Cleaning and inspecting the pipeline. This is accomplished by inserting the pig into a ‘pig launcher’ (or ‘launching station)
