Pipe Freezing
Our pipe freezing technique uses liquid nitrogen to create temporary ice plugs in live pipelines. This non-invasive method allows valve replacements and pipework modifications without system drainage. Clients benefit from reduced downtime and safety risks across water, chemical, and hydrocarbon systems. Our engineers handle carbon steel, copper, and ductile iron pipelines up to 48" diameter.
Hot Tapping
Hot tapping enables branch connections in live pipelines operating under pressure. We install mechanical fittings and drill through valves to maintain system integrity. This technique suits gas, water, and chemical lines in critical environments like hospitals and data centres. Our equipment handles temperatures up to 200C and pressures up to 40 bar.
Line Stopping
Line stopping creates temporary pipeline isolation while maintaining flow through bypass systems. We weld or clamp fittings to steel, copper, or plastic pipelines to install stopping equipment. This method prevents shutdowns for valve installations or pipeline modifications in water, sewage, and industrial chemical systems.
Shrink Fitting
Shrink fitting uses liquid nitrogen to assemble interference-fit components without heat or force. This precision technique suits bearings, shafts, and mechanical joints in industrial equipment. The process eliminates damage risks from traditional fitting methods while enabling assembly of dissimilar materials that cannot be welded.
Pipeline Maintenance
We provide comprehensive pipeline maintenance including valve replacement, pump installations, and system expansions. Our engineers handle steel, stainless steel, and plastic piping systems for heating, water treatment, and industrial processes. Services integrate with core isolation techniques to deliver complete solutions for system upgrades and emergency repairs.
