Pioneering High-Tech Polymer Infrastructure Since Inception
Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of building materials, high-tolerance pipe fittings, and precision injection moulds. Ehao has established itself as a definitive market leader in PVC/UPVC ball valves across China's highly competitive domestic and commercial landscape.
Our research and development pipeline is backed by academic collaborations with the Chinese Academy of Sciences and Zhejiang University, pushing the boundaries of polymer chemistry, structural optimization, and physical stress tolerances. By integrating advanced production technologies, we operate automated manufacturing lines and computer-controlled injection molding systems directly imported from Germany.
Every fitting and valve produced undergoes a rigorous 26-step scientific testing pipeline. This uncompromising quality control protocol ensures a 100% ex-factory pass rate, and guarantees our components exceed international performance criteria, specifically conforming to DIN8077 and DIN8078 standards.
Guided by our core philosophy—"honest, dedicated, innovation and return"—we utilize an engineering-driven business model: prioritizing quality for survival, deploying science and technology for development, utilizing modern management for maximum efficiency, and maintaining premium customer service for global credit.
Serving infrastructure needs across Europe, North & South America, and Southeast Asia.
We develop and manufacture custom plastic moulds based on complex architectural blueprints and physical prototypes.
Addressing the shifting landscape of international infrastructure procurement and supply chain resilience.
Modern commercial infrastructure projects demand materials that mitigate structural degradation, prevent chemical contamination, and assure predictable longevity. As a leading supplier of 12 PVC pipe fittings and high-tolerance UPVC components, Ehao meets the precise requirements of B2B procurement managers, EPC contractors, and agricultural distributors.
Deploying redundant raw material buffers and container optimization algorithms to ensure constant availability of PVC valves and fittings across standard, schedule-based, and bespoke size brackets.
Ensuring compliance with DIN, ASTM, and ISO guidelines. Our specialized engineering services match exact specifications for commercial water lines, chemical transport, and municipal drainage pipelines.
With an independent tool-making facility, we manufacture complex parts, private-label lines, and custom valves directly from physical engineering samples or digital CAD files.
Ehao components are engineered to deliver reliable fluid dynamics across key global industrial sectors.
Safe, non-toxic, and long-lasting piping components designed for domestic potable water networks and interior plumbing lines.
UV-resistant, high-impact fittings engineered for large-scale agricultural operations, drip lines, and rural water redistribution networks.
Chemically inert UPVC components engineered to protect marine life by maintaining stable water quality in recirculating aquaculture systems (RAS).
High-tensile PVC conduits and drainage components designed to withstand structural loads and soil settlement in complex civil engineering works.
Unveiling the structural parameters that give Ehao PVC components superior longevity under high pressure load conditions.
The performance of our PVC and UPVC fittings depends on molecular formulation. Working with the Chinese Academy of Sciences, Ehao's polymer chemists optimize the blend of raw PVC resins, organic heat stabilizers, and impact modifiers. Our formulation eliminates plasticizer migration, ensuring the fittings retain mechanical strength without becoming brittle over decades of environmental exposure.
This structural integrity prevents fatigue failure in high-flow, high-pressure setups, especially in commercial agricultural irrigation and chemical dosing installations.
By integrating automated injection molding lines directly from Germany, Ehao achieves tight structural tolerances down to the micron level. This level of precision eliminates micro-voids, internal weld line weaknesses, and dimensional variances that often cause leaks at connection points.
Our automated processes guarantee consistent socket wall thickness, uniform thread depths, and smooth internal flow channels, reducing pressure drop across the entire system.

Our piping systems conform to German industrial criteria for dimensional stability, pressure tolerances, and temperature limits.
Fittings are engineered to align with ASTM D1784 cell classifications and ASTM D2466 socket dimensions for effortless integration with Schedule 40 and 80 PVC systems.
We source heavy-metal-free, lead-free polymer materials, ensuring our components are safe for drinking water networks and aquaculture.
Expert answers to common engineering, procurement, and technical queries regarding PVC pipe fittings.
Our PVC and UPVC fittings are designed to support standard pressure brackets, including PN10 (1.0 MPa) and PN16 (1.6 MPa) depending on product dimensions and wall thickness. Ehao components undergo hydrostatic pressure verification to ensure structural performance under pressure surges.
Our collaboration with the Chinese Academy of Sciences and Zhejiang University centers on enhancing polymer formulations. This includes research into thermal stabilizers, impact modifiers, and UV inhibitors, allowing our PVC and UPVC components to resist environmental stress cracking (ESCR) and weather exposure.
Yes, our engineering department designs and manufactures custom tooling, molds, and extruded or injection-molded components. We can develop products from digital drawings or physical samples to support your industrial design requirements.
Standard production lead times range from 20 to 30 days post-deposit validation, depending on catalog composition and mold setup requirements. We coordinate logistics schedules to optimize shipping routes to major international ports.
Our quality control program begins with raw material molecular analysis and continues through every stage of production. It includes automated dimensional inspection, drop tests, burst pressure testing, hot-water resistance checks, and cycle-life stress verification for moving components like ball valve spheres.
Durable, chemical-resistant fluid control options designed for agricultural, industrial, and municipal infrastructure projects.
