Industrial UPVC Piping for Chemical, Lithium, and Water Treatment
Zheyi Pipeline (Wuhan) Co., Ltd. is a China-based manufacturer and supplier of Chemical/Lithium UPVC Pipe(DIN/ANSI) Manufacturers product line. Since 2007, we have engineered unplasticized polyvinyl chloride (UPVC) piping systems for demanding fluid handling in chemical processing, lithium battery production, electronics, water treatment, and related industries. Our pipes are manufactured in two vertically integrated factories in East and Central China, combining German and American technology with rigorous quality control.
Our UPVC pipes are available in DIN and ANSI standards, with diameters from DN20 to DN110 and pressure ratings up to 1.6 MPa. They are designed for corrosion resistance, lightweight installation, and long service life, making them a reliable choice for acid and alkali transfer, ultra-pure water, and industrial wastewater systems.
Key Industries: Chemical, lithium battery, metallurgy, photovoltaic, nuclear power, electronics & semiconductor, food, pharmaceutical, automotive, and water treatment.
Product Range and Configuration
We supply UPVC pressure pipes in two primary series: SCH80 (ANSI) and DIN. Each series is available in a range of diameters, wall thicknesses, and pressure classes to match your system requirements. Our pipes are produced in standard 4-meter lengths, with custom lengths available for batch orders.

For a complete system, we also offer matching UPVC/CPVC Fittings and UPVC/CPVC Valve products, ensuring dimensional compatibility and reliable joint integrity.
Material and Performance Specifications
Our UPVC pipes are formulated with high-quality virgin resin, free from plasticizers, ensuring chemical inertness and resistance to UV degradation. Key performance characteristics include:
- Corrosion resistance: Suitable for a wide range of acids, alkalis, and salts.
- Lightweight: Approximately 1/5 the weight of steel, reducing installation costs.
- Low friction coefficient: Smooth inner surface minimizes pressure loss.
- Electrical insulation: Non-conductive, safe for electrical environments.
- Temperature range: -10°C to 60°C for continuous operation.
We test each batch for density, Vicat softening temperature, longitudinal reversion, and hydrostatic pressure integrity, ensuring compliance with GB/T 4219.1 and ASTM D1785 standards.
Engineering and Customization
Our engineering team works with you to define the correct pipe series, diameter, wall thickness, and pressure class based on your fluid characteristics, operating temperature, and flow requirements. We offer customization in:
- Pipe length (standard 4m, custom up to 12m)
- Color coding (e.g., gray, white, or custom)
- End preparation (plain, socket, or threaded)
- Packaging (bundles, pallets, or containers)
For projects requiring high-purity water or food-grade applications, we ensure materials meet relevant sanitary standards, and we can provide documentation upon request.
Quality Assurance and Testing
Our manufacturing facilities are ISO 9001, ISO 14001, and ISO 45001 certified. We hold a Production License for Special Equipment and a Zhejiang Province water-related products sanitary license. Each production lot undergoes:
- Hydrostatic pressure tests at 20°C and 60°C
- Falling weight impact tests at 0°C
- Oven and immersion tests for material integrity
- Dimensional and visual inspections
We also provide test reports and certificates of conformity with each shipment, ensuring full traceability.
Installation and Maintenance
UPVC pipes are typically joined using solvent cement or threaded connections. We provide installation guidelines covering support spacing, thermal expansion compensation, and pressure testing procedures. Our technical team is available to assist with on-site troubleshooting and maintenance planning.
With a service life exceeding 50 years under proper conditions, our pipes require minimal maintenance, reducing lifecycle costs.
Information We Use to Configure Your Solution
To prepare an accurate quotation and configuration, please provide the following project details:
- Fluid type and concentration (e.g., 30% HCl, ultrapure water)
- Operating temperature and pressure
- Required flow rate or pipe diameter
- Installation environment (indoor/outdoor, UV exposure)
- Applicable standards (DIN, ANSI, or other)
- Quantity and delivery location
With this information, we can recommend the optimal pipe series and provide a detailed proposal, including technical drawings and delivery schedules.
Global Supply and Support
We export to Europe, America, Southeast Asia, and other regions, with over 30 sales offices in China. Our logistics team ensures safe packaging and timely delivery, whether by sea, air, or land. We also offer after-sales support to ensure your system operates reliably.
Frequently Asked Questions
Q: What is the difference between DIN and ANSI UPVC pipes?
A: DIN pipes follow European metric dimensions, while ANSI pipes use imperial sizes (e.g., SCH80). We manufacture both to meet your project's regional standards.
Q: Can you provide custom lengths or colors?
A: Yes, we offer custom lengths in batch orders and can match specific color requirements for identification.
Q: How do I ensure the pipe is suitable for my chemical?
A: Provide us with the chemical name, concentration, and temperature. Our engineers will verify chemical compatibility and recommend the appropriate pipe grade.
Q: What is the minimum order quantity?
A: MOQ varies by size and series; typically, we can accommodate small trial orders for testing.
Q: Do you provide installation training?
A: Yes, we offer technical documentation and remote support. For large projects, on-site training can be arranged.
