EASTBOOM® is a China-based manufacturer of N-HAP Hot-Dip Coated Steel Pipes. Our pipes are crafted by coating steel pipes with a layer of PE, blending the strengths of both steel and plastic pipes. They boast stronger compressive strength than regular plastic conduits and better corrosion resistance than ordinary steel pipes—making them an ideal choice for cable protection.
N-HAP hot-dip coated steel pipes are a new generation of anti-corrosion materials, produced via fluidized bed dipping technology. They stand out with high mechanical strength, strong pressure resistance, and excellent electrical insulation, along with high hardness, smooth inner and outer surfaces, and a low friction coefficient. Additional advantages include good flame retardancy and extremely low water absorption (less than 0.003%), plus a broad operating temperature range of -40℃ to 120℃.
Key Features & Applications
What Makes It Stand Out
Weather & Low-Temp Resistant
Made for long-term buried use, our N-HAP hot-dip coated steel pipes work reliably from -40℃ to 100℃. They hold up perfectly under tough conditions like frost, extreme heat, and humidity—no problem.
Smooth Inner Wall
The inside is super smooth with no burrs, so cables slide right through during installation. This avoids scratches or damage to the insulation, saves time on setup, and cuts down on future maintenance.
Corrosion & Aging Resistance
-Inner/outer resin coating ensures chemical stability, resists corrosion, rust, and aging
High Mechanical Strength
-Comparable to steel pipes in impact, bending, and pressure resistance; long service life, -outperforms standard plastic mining pipes
Strong Coating Adhesion
-Adhesion strength ≥35 N/cm, low water absorption (<0.0003%), excellent water immersion resistance
Self-Lubricating
-Our N-HAP Hot-dip Coated Steel Pipes have smooth inner wall prevents scaling, reduces flow resistance, increases throughput by 30%
Flexible Connection Methods
-Socket/spigot joints, clamp connections, compatible with flanges and quick couplers
Corrosion & Scaling Resistance
-Suitable for high-sulfur water and water containing calcium/magnesium ions, low maintenance costs
Eco-Friendly & Safe
-PE polyethylene powder coating, non-toxic, odorless, and clean
Lightweight
-Easier to transport and install compared to traditional steel pipes
Applications:
1.Our N-HAP Hot-dip Coated Steel Pipes are used in underground protection for power/communication cables
2.Bridge/river/road-crossing conduit for cables
3.Mine cable protection pipes
4.Reclaimed water/seawater transport
5.Drainage and sewage systems
6.Corrosive fluid transport in petroleum/chemical industries
