Explore our core engineering-grade products designed for optimal municipal, industrial, and agricultural fluid networks.
In modern industrial fluid networks, high-density polyethylene (HDPE) and associated thermoplastic systems have fundamentally replaced traditional ductile iron, carbon steel, and concrete conduits. The driving force behind this global paradigm shift lies in the material's structural immunity to galvanic corrosion, high resistance to crack propagation, and its superior flexibility under shifting geodetic conditions.
According to international infrastructural metrics, municipal water distribution schemes lose upwards of 20-30% of treated water annually due to joint failures in rigid metallic lines. By integrating high-molecular-weight polyethylene resins combined with advanced electrofusion and butt-fusion connection techniques, modern engineering networks achieve a monolithic, leak-free continuous structure capable of maintaining structural integrity for over 100 years.

| Joint Integrity | Monolithic Fusion (Zero leaks) | Mechanical Gaskets (Leak-prone) | Solvent Weld / Threaded |
| Flexibility & Radius | High (Bends with soil shifts) | Rigid (Requires extra fittings) | Rigid / Semi-flexible |
| Operational Lifespan | 100+ Years | 30-50 Years | 50+ Years |
Ehao Plastic Group stands as a premier high-tech private enterprise. Our capabilities encompass the comprehensive research, development, and high-volume manufacture of premium piping materials, connection fittings, and custom injection moulds. In particular, Ehao Plastic Group has established itself as an authoritative leader in PVC/UPVC and high-integrity thermoplastic components within the domestic Chinese market and international territories.
Since our inception, our technology division has collaborated with the Chinese Academy of Sciences and Zhejiang University to engineer high-resilience molecular compounds. To ensure absolute compliance with global mechanical constraints, we operate automated, computerized injection molding systems sourced directly from Germany. Every single product passes through an exhaustive 26-step scientific testing regimen, assuring a 100% factory qualification rate under DIN8077 and DIN8078 standards.
Guided by our foundational philosophy of "honest, dedicated, innovation and return", we implement an operational framework centered on *quality for survival, science and technology for development, management for benefits, and service for credit*. Ehao provides international clients with highly optimized material properties, logical cost-structures, and professional engineering support.
Configured to meet the rigorous physical and environmental demands of diverse commercial and civil projects.
Pioneering the next generation of smart, high-pressure polyolefin fluid systems.
By optimizing the short-chain branching structure within the high-density polyethylene polymer chains, PE100-RC achieves unparalleled resistance to Point Loading and Slow Crack Growth (SCG). This allows for trenchless installations and sandless backfilling, reducing installation overheads by up to 40%.
Integrating barcode tracking and modern microprocessors into electrofusion fitting operations. Fusion units scan built-in smart chips to adjust heat duration and voltage according to ambient temperatures, preventing under-welding or polymer degradation.
Our raw material synthesis utilizes 100% recyclable thermoplastic structures. Polyethylene fluid components present a significantly lower carbon footprint compared to copper or stainless steel, aiding municipal builders in achieving carbon neutrality certifications.

PE100 resins feature a higher Minimum Required Strength (MRS) of 10 MPa at 50 years under 20°C, compared to 8 MPa for PE80. This allows PE100 fittings to achieve thinner wall designs at equivalent pressure ratings, thereby increasing internal flow area and reducing overall piping transport weights.
Our manufacturing framework utilizes German injection molding machinery integrated with a strict 26-step scientific checking sequence. This includes raw molecular weight assessment, hydrostatic pressure tests under variable thermal loads, dimension verification, and impact torque validation. Our technical metrics fully satisfy DIN8077 and DIN8078 standards.
For large-diameter mains, butt fusion is highly cost-effective and provides high structural integrity. For congested spaces or distribution lines with frequent changes in size or direction, electrofusion is recommended due to its localized heat distribution, repeatable parameters, and minimal operator-bias error rates.
Yes. Thermoplastics like HDPE, PVC, and PP display high chemical inertness. Unlike metals, they do not undergo electrochemical oxidation when exposed to strong acids, bases, or saline solution profiles. For detailed chemical compatibility matrixes, consult our technical engineering team with your process fluid's chemical composition and temperature.
Ehao develops in-house steel injection moulds. We accept customer-furnished CAD/3D blueprints, chemical specifications, and physical samples to design tailored extrusion and injection products, serving various civil and municipal applications globally.
