Trenchless rehabilitation for natural gas distribution and district heating networks
Natural gas and district heating pipelines require rehabilitation methods that deliver superior gas-tightness, high-temperature resistance, and rapid installation to minimize service interruption. Our flexible composite liner hose is engineered specifically for these demanding services.
Different damage profiles, host materials, and operating conditions require different rehabilitation approaches. Here are the methods best suited for this application sector.
Flexible composite liner hose repair utilizes a hose formed through the co-extrusion of a high-strength woven fiber core, an ultra-wear-resistant PE layer, and a highly gas-tight polyurethane material. This hose is installed into existing natural gas and heating pipelines using a pulling method, offering rapid construction speeds and a long service life.
For gas pipelines requiring full pressure-retentive structural repair, FIPP thermoplastic forming creates a seamless monolithic inner pipe inside the host. Operating temperature range -30°C to 55°C accommodates buried gas pipelines in temperate and continental climates.
Send us pipe diameter, length, host material, and conveyed media — we'll recommend the optimal liner system and curing method.
