As a leading high-tech private enterprise, Ehao Plastic Group integrates cutting-edge Research & Development with state-of-the-art production of building materials, large-diameter pipe fittings, and high-performance injection molds. Our established industry leadership is particularly recognized in the domestic and global PVC/UPVC ball valves and industrial piping system sectors.
Leveraging deep technological partnerships with the Chinese Academy of Sciences and Zhejiang University, Ehao group bridges the gap between academic innovation and physical engineering. By introducing automated injection molding systems directly imported from Germany, we maintain rigorous control over tolerance, material composition, and structural strength.
Every single PVC component, including our specialized 10-inch pipe fittings, is put through 26 separate scientific testing steps, assuring a verified 100% ex-factory pass rate. Our production indexes comply comprehensively with global standards, including DIN 8077 and DIN 8078, delivering world-class reliability to civil, industrial, and agricultural piping projects.
Direct technology transfers from China’s leading scientific institutions ensure advanced polymer formulation and molecular stability.
Utilizing high-end German injection technology ensures flawless mechanical consistency across large dimensions.
From resin verification to hydrostatic and burst pressure evaluations, quality is strictly monitored.
Our systems conform to standard DIN 8077/8078, ASTM, and ISO guidelines to integrate seamlessly into international projects.
In modern industrial and municipal piping systems, 10-inch PVC pipe fittings have emerged as a vital standard. Globally, pipeline systems are transitioning away from heavy, corrosion-prone metallic materials such as cast iron and carbon steel toward high-durability thermoplastic compounds. UPVC (Unplasticized Polyvinyl Chloride) offers significant advantages due to its chemical inertness, high strength-to-weight ratio, and low friction coefficient, which maximizes flow efficiency while minimizing scaling and corrosion over long operational lifespans.
This shift is heavily driven by municipal water supply expansions, large-scale agricultural modernization, and heavy chemical industrial requirements. The global market demand for wholesale 10-inch PVC fittings has experienced steady annual growth, especially in North America, Europe, and rapidly developing zones in Southeast Asia and South America. High-performance pipeline systems are now required to guarantee maintenance-free operations for over 50 years, directing global procurement officers to seek out vertically integrated manufacturers capable of supplying high-capacity, certified heavy-duty fittings.
The manufacturing of large-format thermoplastic components, such as 10-inch PVC elbows, tees, and flanges, demands highly specialized tooling. Ehao Plastic Group integrates high-tech injection molds, designed and manufactured in-house, with advanced computer-controlled injection molding machinery. Our Facility 4.0 layout reduces material waste, guarantees dimensional stability, and eliminates the risk of internal voids or structural weak points that commonly plague low-tier, gravity-fed extrusion lines.
This integration of technology significantly benefits our international procurement partners. By controlling both the design of precision molds and the final plastic injection process, Ehao group offers comprehensive OEM and ODM support. Clients can provide engineering drawings or physical samples, and our engineers can develop customized tooling profiles to fit specific mechanical tolerances and regional building code requirements.
Global supply networks face constant logistical challenges, making reliability and supply chain flexibility critical for major infrastructure projects. Operating in China's advanced manufacturing hubs, Ehao Group maintains robust access to high-quality raw materials, reliable energy grids, and major international deep-water ports. This strategic positioning allows us to fulfill large-scale wholesale orders quickly and reliably, helping to buffer our global clients against local supply shortfalls and fluctuating market prices.
From complex commercial construction to high-volume commercial aquaculture, 10-inch PVC pipe fittings serve as the structural backbone for major fluid transport systems. Our fittings and matching valves are engineered to perform reliably across a wide range of operational environments:
Home Decoration
Irrigation System
Fish Cultivation
Construction Work
Provides low friction loss and long-term chemical resistance against corrosive soils and municipal effluents, preventing scale accumulation.
Ideal for chemical facilities moving diluted acids, alkalis, and industrial salts. The inert polymer profile avoids corrosion risks common with steel pipelines.
Delivers high volumetric water flow rates to modern farming networks. Withstands dynamic field pressure variations while minimizing chemical degradation from fertilizers.
Ensures a completely non-toxic environment for marine life. Unlike metal piping, Ehao’s clean PVC formulation will not leach trace metal ions into sensitive aquatic systems.
To help design engineers, procurement specialists, and project managers construct reliable, long-lasting pipeline infrastructures, we maintain strict dimensional standards. Below is the technical reference dataset for our wholesale large-diameter PVC fittings, aligned with international ASTM and DIN engineering requirements.
| Nominal Size (Inches) | Outer Diameter (mm) | Wall Thickness (Schedule 80 - mm) | Working Pressure (at 23°C / 73°F) | Applicable Standards |
|---|---|---|---|---|
| 10 Inch | 273.0 mm | 15.06 mm | 230 PSI (1.58 MPa) | ASTM D2467 / DIN 8063 |
| 8 Inch | 219.1 mm | 12.70 mm | 250 PSI (1.72 MPa) | ASTM D2467 / DIN 8063 |
| 6 Inch | 168.3 mm | 10.97 mm | 280 PSI (1.93 MPa) | ASTM D2467 / DIN 8063 |

Ehao Group partners with Methods Machine Tools to support clients at every stage of their workflow—from choosing and configuring the right production machinery to assisting with investment financing to ensure reliable project margins. This collaborative approach enhances our engineering accuracy, enabling us to deliver dependable fluid control products to our global business partners.
Ehao's 10-inch UPVC fittings provide excellent chemical resistance to a wide range of industrial acids, alkalis, salts, and oxidizers. They remain chemically inert in most municipal, marine, and industrial wastewater environments. However, they are not recommended for transporting highly concentrated polar organic solvents, such as esters, ketones, and chlorinated hydrocarbons, which can soften the polymer matrix.
Large fittings are vulnerable to internal cooling voids and shrink marks during manufacturing. Ehao prevents these defects by using computer-controlled injection molding machinery imported from Germany, combined with customized molds developed alongside researchers from Zhejiang University. We also run every batch through a strict 26-step testing protocol that includes hydrostatic pressure tests, burst tests, and dimensional verification.
Our piping systems and fittings conform fully to DIN 8077 and DIN 8078 standards. In addition, our manufacturing processes are ISO 9001 certified, and our product tolerances align with ASTM D2467 Schedule 80 specifications, ensuring seamless integration into engineering projects worldwide.
