Line stopping (flow stopping) is a means of temporarily isolating a pressurised pipeline without any interruption to flow and customer services to enable planned and emergency installations to be completed. Reservoir/ digester wall tapping (hot tapping) cores a hole through a reinforced concrete retaining structure without draining down.
Underpressure valves are permanent resilient wedge gate valves that can be installed on any pipe material with pressure up to 16 bar. Pipe cutting (cold cutting) is a safe method of cutting out a section of pipeline in a controlled manner, leaving a machined finish to the pipe end.

Line stopping (flow stopping) is a means of temporarily isolating a pressurised pipeline without any interruption to flow and customer services to enable planned and emergency installations to be completed. Line stopping (flow stopping) can be carried out on most pipelines working at pressures up to 25 bar, including, cast iron, ductile iron, steel, PVC, asbestos cement, MDPE, HDPE and PSC.
Underpressure valves are permanent resilient wedge gate valves that can be installed on any pipe material with pressure up to 16 bar. By only milling an insertion slot, we maintain the pipeline integrity unlike other underpressure valves. These underpressure valves can be inserted in the minimum of time with only a small excavation and no interruption to customer supply.
