Industrial UPVC/CPVC Pipe (DIN/ANSI) Manufacturers

Industrial UPVC/CPVC Pipe (DIN/ANSI) Manufacturers

As a Industrial UPVC/CPVC Pipe (DIN/ANSI) Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

Zheyi Pipeline (Wuhan) Co., Ltd. is a specialized manufacturer of industrial UPVC and CPVC piping systems in DIN and ANSI standards. Since 2007, we have focused on engineering corrosion-resistant, high-temperature-capable pipe, fittings, and valves for demanding process environments. Our product range covers pressure pipes, injection-molded fittings, manual and actuated valves, plus membrane filtration components for water treatment. We serve chemical processing, lithium battery production, metallurgy, electronics and semiconductor fabrication, and industrial water treatment plants worldwide.

As a China-based factory with two integrated manufacturing hubs in Jiaxing and Wuhan, we control the entire production chain—from raw material selection to final performance testing. Our engineering team configures each system based on your working pressure, temperature, media, and installation layout, ensuring the piping matches your process rather than forcing a generic solution.

Our Range and Application Fit

We supply a complete thermoplastic piping ecosystem, not just individual components. Each product line is engineered for specific service conditions:

Material Selection: UPVC vs. CPVC

Choosing the right material is the first step in designing a reliable piping system. Our engineers evaluate the chemical compatibility, operating temperature, and pressure requirements of your media.

• UPVC (unplasticized PVC): Excellent corrosion resistance to most acids, alkalis, and salts at ambient temperatures. It is lightweight, economical, and ideal for water supply, drainage, and low-temperature chemical transfer. We produce UPVC pipes from DN20 to DN110, following ISO 4422 and ASTM D1785.
• CPVC (chlorinated PVC): Withstands continuous service up to 90°C (194°F) and offers superior chemical resistance to hot corrosive media. CPVC is the preferred choice for hot acid/alkali lines, industrial wastewater, and processes where temperature exceeds UPVC limits.

For both materials, we use high-grade raw materials from established suppliers (e.g., Sekisui, Lubrizol) to ensure consistent mechanical and chemical properties. Our production lines are equipped with advanced extrusion and injection molding machinery, and we perform in-house testing including density, Vicat softening, hydrostatic pressure, and impact resistance.

Engineering and Customization

We understand that every project has unique requirements. Our engineering team works with you to customize pipe dimensions, wall thickness, pressure ratings, and fitting configurations. We can supply standard SCH80/DIN products or develop special solutions for non-standard connections, such as flanged or threaded ends, and integrate with existing metal or plastic piping systems.

For automated processes, we offer valves with electric or pneumatic actuators, and we can provide technical documentation for control system integration. Our goal is to ensure that the piping system not only meets your process specifications but also simplifies installation and maintenance.

Quality Assurance and Compliance

Quality is built into every stage of our manufacturing. We hold ISO 9001, ISO 14001, and ISO 45001 certifications, along with a Special Equipment Production License and Zhejiang Province water-related product hygiene approval. These certifications reflect our commitment to consistent quality, environmental responsibility, and occupational safety.

Our testing laboratory performs rigorous checks on every batch:

• Density test for material uniformity
• Vicat softening temperature test for heat resistance
• Oven test for long-term thermal stability
• Hydrostatic pressure test for burst strength
• Drop hammer impact test for mechanical durability

These tests ensure that our pipes and fittings can withstand the stresses of installation and operation, reducing the risk of leaks and failures in your facility.

Installation and Maintenance Support

We provide comprehensive technical support to ensure successful installation and long service life. Our team can supply installation guidelines, recommend appropriate solvent cement or threading methods, and advise on thermal expansion compensation. We also offer training for your installation crew, either on-site or via documentation, to minimize errors.

Maintenance is straightforward with our systems: the smooth inner surface of UPVC/CPVC pipes reduces scaling and fouling, and the corrosion-resistant nature eliminates the need for protective coatings. We stock spare parts for valves and fittings, and our global logistics network ensures timely delivery of replacements.

Information We Use to Configure Your Solution

To prepare an accurate quotation and technical proposal, we need the following project details:

• Media: Chemical composition, concentration, pH, and any solids content
• Operating conditions: Maximum and normal temperature, pressure, and flow rate
• Pipe size and length: Required diameters, total run, and number of fittings
• Connection type: Solvent weld, threaded, flanged, or other
• Standards: DIN, ANSI, or other applicable specifications
• Installation environment: Indoor/outdoor, UV exposure, seismic or vibration considerations
• Automation needs: Whether valves require actuation and control system integration

With this information, we can recommend the optimal material grade, pressure class, and component configuration. We also provide drawings and data sheets for your review before production.
