Five product lines covering steel pipe, coated pipe, anti-corrosion pipe, insulated pipe and fittings. DN200–DN3800 spiral, DN15–DN3800 coating, executed to GB/T 3091, GB/T 9711 and SY/T 5037.
Spiral submerged-arc welded (SSAW) as the core, supplemented by seamless, ERW straight-seam, JCOE LSAW and hot-dip galvanized pipe — multiple double-sided SAW lines, annual output 120,000 tonnes.
| Product | Diameter | Standard | Typical Use |
|---|---|---|---|
| SSAW spiral pipe | DN200–DN3800 | GB/T 9711 / SY/T 5037 | Oil & gas, water mains, piling |
| Seamless pipe | Various | GB/T 8163 etc. | High-pressure fluid, mechanical |
| ERW straight-seam pipe | Small to medium | GB/T 3091 | Water, gas, structure |
| JCOE LSAW pipe | Large diameter | GB/T 9711 | Long-distance trunk lines |
| Hot-dip galvanized pipe | Small diameter | GB/T 3091 | Fire sprinkler, water supply |
Steel pipe substrate with a fused epoxy/PE layer inside and out — the strength of steel plus the corrosion resistance of plastics. Our self-developed large-diameter coating line reaches DN3800, the largest in North China.
Hygiene licence for drinking water; inner EP outer PE; for city water supply networks.
Red inner-outer coating for sprinkler and standpipe systems in buildings.
MA mining safety certificate; anti-static & flame-retardant for mine duties.
Mechanical protection outside, corrosion resistance inside — for buried water & gas mains.
For cable protection in power projects; socket or flanged joints available.
Prefabricated grooves or flanges with intact coating — fast installation.
General-purpose composite pipe for building water supply and HVAC.
From lab-scale small bores to DN3800 trunk mains on the same coating line.
Dedicated anti-corrosion plant, 200,000 ㎡ annual capacity. External coating isolates the pipe from soil, water and chemicals; internal lining protects against conveyed media — extending service life and safeguarding oil, gas and water projects.
FBE + adhesive + PE; the mainstream external protection for buried gas & oil mains.
Fused-bonded epoxy inside, PE outside; widely used for water transmission & drainage.
Non-toxic epoxy coating certified for drinking-water tanks and mains.
3 oil 2 cloth / 4 oil 3 cloth / 6 oil 2 cloth reinforced grades for buried steel pipe.
Single or dual-layer FBE for pipeline duties with strong adhesion and abrasion resistance.
Internal cement-mortar lining for large water mains — proven, economical, long service life.
Dedicated insulation plant. Working pipe + insulation layer + outer casing — cuts heat loss, keeps temperature and saves energy for district heating and oil duties.
HDPE outer casing + PU foam; the mainstream choice for buried district-heating networks.
Double steel casing for steam networks, up to 350℃ working conditions.
For city heating sources, heat-exchange stations and thermal-oil circuits.
FRP casing for corrosive environments; galvanized-iron cladding for overhead runs.
A complete fitting package matched to the pipe line: elbows, flanges, tees, reducers, valves, expansion joints, blinds, waterproof sleeves and compensators — one order, one shipment, one point of responsibility.
Welded, flanged, bimetal, grooved, double-seal flanged, socket and threaded joints — site conditions decide, we fabricate accordingly.
Standard for buried mains; strongest joint.
For valves, pumps and equipment interfaces.
For coating continuity at joints.
Fast mechanical coupling for fire & HVAC lines.
Tight joints for coated pipe without damaging coating.
For power conduit and drainage duties.
Small-bore galvanized & coated pipe.
Send us the drawing; we pre-fabricate joints accordingly.
Raw coils with mill certificates; chemical analysis and mechanical tests on every batch; third-party inspection welcome.
