Cangzhou Youcheng Pipeline Technology Co., Ltd. manufactures spiral welded, anti-corrosion coated and pre-insulated steel pipes — DN200 to DN3800, one factory, one quality standard.
Founded in 2012 and located in the Yanshan Economic Development Zone, Hebei — China's pipeline equipment manufacturing base — Cangzhou Youcheng Pipeline Technology Co., Ltd. is a specialized manufacturer of double-sided submerged arc spiral welded steel pipes, anti-corrosion pipes and pre-insulated pipes.
With registered capital of RMB 50 million and a team of 110+ people, we produce spiral welded pipes from DN200 to DN3800 with wall thickness 5–25 mm, to GB/T 3091, GB/T 9711 and SY/T 5037 standards. Our in-house coating and insulation workshops process FBE / 2FBE / 3PE / TPEP anti-corrosion pipes, polyurethane pre-insulated pipes and steel-jacket steam-insulated pipes.
From base pipe to coating, insulation and matching fittings — one factory, one quality standard, one accountable partner.
Double-sided submerged arc spiral welded pipe for water, structure and piling.
FBE / 2FBE / 3PE / TPEP systems for buried gas, water and sewage lines.
Direct-buried polyurethane pre-insulated pipe for district heating networks.
Steel-jacket steam insulation for high-temperature steam transmission.
Plastic-coated pipes for water supply, fire fighting, mining and cable protection.
Elbows, tees, reducers, flanges and valves matched to the main line — one order, one shipment.
Independent laboratory plus in-line inspection. Every pipe carries a heat/batch number — traceable from steel coil to dispatch.
Hygiene-certified coatings; cement-mortar lining for trunk mains.
PU pre-insulated and steel-jacket steam pipes for heating networks.
3PE external coating to GB/T 9711 for city gas trunk lines.
MA-certified anti-static, flame-retardant coated pipes.
Gathering lines and plant piping with FBE / 3PE systems.
From plateau geothermal heating in Tibet to Belt & Road mining projects overseas — selected references below.
Geothermal district heating on the plateau; PU pre-insulated steel pipe supplied for 4,500 m altitude service.
County-wide central heating network replacement, with PU pre-insulated steel pipe supplied in batches.
Urban underground network renewal with PU pre-insulated steel pipe; the old-to-new changeover was made without stopping the heat supply.
Complete supply of circulating water pipe and fittings for a gas-turbine demonstration power plant.
Diameter range, wall-thickness capability, weld seam length and economics — the four dimensions that decide a long-distance pipeline.
Epoxy + adhesive + polyethylene: three layers with three jobs. Field joint closure and holiday detection decide the service life.
County-level heating networks across northern China are being renewed. Work is squeezed into the non-heating season, which raises the bar on staged delivery and changeover without shutting down the heat.
