Services
Pipe Freezing
Pipe freezing uses liquid nitrogen to create temporary ice plugs in pressurised pipelines. This allows safe valve replacement and pipework modifications without draining systems. Our controlled freezing process maintains operational pressure while enabling modifications, saving time and reducing environmental impact by avoiding fluid disposal.
Hot Tapping
Hot tapping creates new pipeline connections while systems remain operational. Using specialist equipment, we drill into pressurised pipelines up to 48" diameter with pressures up to 1480 psi. This maintains continuous flow during modifications, eliminating production downtime for critical infrastructure in water, oil, and gas sectors.
Line Stopping
Line stopping enables temporary isolation of pipeline sections without shutting down entire systems. By installing bypasses, we maintain flow while performing repairs or modifications. This technique works with various pipeline materials and fluids, providing cost-effective solutions for complex maintenance requirements in live systems.
Mechanical Pipework
Our mechanical pipework services include valve replacement and system repairs using welded, screwed, or fused connections. With expertise in steel, copper, stainless steel, and plastic pipework, we handle projects from small commercial installations to large-scale industrial systems. Prefabrication facilities ensure precision components for rapid on-site assembly.
Heating & Plumbing
Specialist heating, plumbing, and gas services for the leisure sector include commercial kitchen installations and full building refurbishments. Gas Safe registered engineers deliver complete solutions from boiler replacements to new system designs. Projects include pipework, radiators, hot water systems, and ventilation installations with full certification and commissioning.
