Isolate live pipelines.
Without the shutdown.
Hot tapping, line stopping and pipe freezing on live systems — so your plant keeps running while we work. Family-run specialists trusted across the UK and internationally.
Four ways to work on a live line
Hot Tapping
New branch connections drilled into live pipelines under pressure.
Line Stopping
Isolate a section of pipe while the rest of the system keeps flowing.
Pipe Freezing
Temporary ice plugs stop flow for maintenance with no drain-down.
Mechanical Pipework
Installation, alteration and maintenance of industrial pipework.
Alongside the four core isolation methods, we cover the full scope of live pipework support.
Onsite Welding
Coded welding carried out on site, from repairs to new fabrication.
SP-05Valve Repair
In-situ repair and replacement without draining the system down.
SP-06Pipeline Repair
Permanent repairs to damaged or corroded pipework, live or shut down.
SP-07Leak Sealing
Live sealing on pipework, flanges and valves while under pressure.
SP-08Probe Insertion
Sensors and probes fitted into live lines under full working pressure.
SP-09Clean Steam Pipework
Stainless installations for pharmaceutical and food-grade systems.
SP-10Petrochemical Pipework
Fuel and process pipework for terminals, refineries and tank farms.
SP-11Pipework Contracts
Full mechanical contracts taken from survey through to handover.
SP-12From callout to live isolation
Callout & survey
Tell us the line size, pressure and medium. We assess the isolation method, same day for emergencies.
Method statement
Fixed quote with full RAMS. You know the cost, the method and the timeline before we arrive.
Live isolation
Hot tap, line stop or freeze performed on the live system. Your plant keeps running throughout.
Handover
Completion fittings installed, system verified, full documentation handed over. No return visits needed.
Recent case studies
Live hot tap on 12" fuel line
New branch connection drilled under pressure at a fuel terminal, with zero downtime for the operator.
Double line stop for main diversion
Twin line stops isolated a trunk main section for diversion works while supply stayed live.
Freeze isolation on clean steam
Ice-plug isolation allowed valve replacement on a clean steam system with no production loss.
