Chemical/Lithium UPVC/CPVC Fittings(DIN/ANSI) Manufacturers
As a Chemical/Lithium UPVC/CPVC Fittings(DIN/ANSI) Manufacturers, Zheyi Pipeline (Wuhan) Co., Ltd. engineers and produces a complete range of injection-molded fittings for aggressive chemical and high-purity fluid systems. Our factory in Xiaogan, Hubei, operates under ISO 9001, ISO 14001, and ISO 45001 certified processes, with raw materials sourced from leading global suppliers. We supply elbows, tees, couplers, flanges, and adapters in both UPVC and CPVC, available in Schedule 80 (ANSI) and DIN standard dimensions.
Our fittings are used across lithium battery production, chemical processing, electronics fabrication, and water treatment plants. We support projects from material selection to line integration, providing dimensional data, pressure ratings, and installation guidance. This category page outlines our product range, application fit, and the technical information we use to prepare a tailored proposal.
Product Range and Positioning
We manufacture a broad selection of socket and threaded fittings to match your piping system. Each fitting is produced with tight tolerances and consistent wall thickness to ensure reliable solvent-cement joints and long-term pressure integrity.
Tees and Crosses
For branching or merging flow lines. Available as equal, reducing, and cross configurations.
Elbows (90° and 45°)
Change flow direction with minimal pressure drop. Smooth interior surfaces reduce friction.
Couplers and Adapters
Connect pipes of same or different diameters. Male adapters allow transition to threaded metal components.
Flanges and Gaskets
Provide demountable joints for maintenance access. Looper and blind flanges suit various pressure classes.
Reducer Bushings and Caps
Transition pipe sizes or terminate lines securely. Caps protect open ends during installation.
UPVC vs. CPVC Fittings
Our UPVC fittings are formulated for cold water, drainage, and many chemical services up to 60°C. They offer excellent corrosion resistance and are economical for large-diameter systems. CPVC fittings, with a higher chlorine content, withstand continuous service up to 93°C, making them suitable for hot chemical solutions and industrial hot water lines.

Application Fit and Industry Use
Our fittings are engineered for demanding environments where metallic components would corrode or contaminate the process. In lithium battery plants, CPVC fittings handle electrolyte solvents and acidic byproducts. In chemical processing, they resist concentrated acids and caustic alkalis. For electronics and semiconductor fabrication, the non-conductive nature of UPVC/CPVC prevents galvanic issues, and smooth surfaces minimize particle entrapment.
We also serve water treatment infrastructure, including RO systems and ultrapure water loops. Our fittings meet the dimensional requirements of DIN and ANSI standards, ensuring compatibility with international piping systems.
Critical Specifications and Sizes
We offer fittings from DN20 to DN315 (1/2" to 12") in both UPVC and CPVC. Each product page includes detailed dimensional tables for DIN, ANSI, and JIS socket dimensions. For example, our SCH8O/DIN UPVC/CPVC Tee lists socket depths, outer diameters, and lengths for every size. This data is critical for designing solvent-cement joints and ensuring proper alignment.
- Socket depth and internal diameter tolerance per DIN/ANSI
- Wall thickness consistent with Schedule 80 pressure ratings
- Surface finish for low friction and easy cleaning
- Color coding: UPVC in gray, CPVC in light orange for identification
Quality Assurance and Testing
Every fitting undergoes rigorous quality control in our in-house laboratory. We perform density tests, Vicat softening temperature tests, oven aging tests, hydrostatic pressure tests, and drop hammer impact tests. These procedures verify that our products meet the mechanical and thermal demands of your application. Our quality management system is ISO 9001 certified, and we hold ISO 14001 and ISO 45001 for environmental and occupational health safety.
We also maintain a Production License for Special Equipment and a Zhejiang Province water-related products sanitary license, confirming suitability for potable water contact.
Customization and Configuration
We understand that standard fittings may not always fit your existing layout. We offer customization in terms of socket dimensions, wall thickness, and even material formulation for specific chemical resistance. Our engineering team can review your piping isometric drawings and recommend the appropriate fitting types and sizes. We also provide non-standard colors or branding on request.
For large projects, we can coordinate production of matching UPVC Pipe and CPVC Pipe to ensure consistent material properties and joint compatibility.
Installation and Maintenance
Our fittings are designed for solvent cement welding, which creates a strong, leak-free joint. We provide installation guidelines covering surface preparation, cement application, and curing times. For flanged connections, we supply gaskets and recommend torque values for bolting. Proper installation is essential to achieve the rated pressure and temperature performance.
Maintenance is minimal due to the corrosion-resistant nature of UPVC/CPVC. Periodic inspection for mechanical damage or chemical attack is sufficient. We offer spare parts such as flange gaskets and can supply replacement fittings quickly from our inventory.
Information We Use to Configure Your Solution
To prepare a precise quotation and technical proposal, we need the following project information:
- Fluid type, concentration, and temperature
- Operating pressure and required safety factor
- Pipe material and standard (DIN, ANSI, JIS)
- Nominal diameters and quantity per fitting type
- Installation environment (indoor/outdoor, UV exposure)
- Any special certifications or documentation required
With this data, we can confirm material selection, provide dimensional drawings, and schedule production to meet your timeline.
FAQs
What is the difference between UPVC and CPVC fittings?
UPVC is suitable for cold water and lower-temperature chemical service up to 60°C. CPVC can handle hot liquids up to 93°C and offers higher impact strength at elevated temperatures. Choose CPVC for hot chemical lines and hot water systems.
Do you provide fittings in both DIN and ANSI standards?
Yes, we manufacture fittings to DIN and ANSI (Schedule 80) dimensions. Our product tables list socket dimensions for both standards, allowing you to select the correct series for your piping system.
Can you customize fittings for special applications?
We can adjust socket dimensions, wall thickness, and material formulation to meet specific chemical or pressure requirements. Contact us with your application details, and our engineers will evaluate the feasibility.
What quality certifications do your fittings hold?
Our manufacturing facilities are ISO 9001, ISO 14001, and ISO 45001 certified. We also hold a Production License for Special Equipment and a water-related products sanitary license, ensuring compliance with international quality and safety standards.
How do you ensure the dimensional accuracy of fittings?
We use precision injection molding machines and perform 100% dimensional inspection on critical sockets. Our quality control includes regular testing of wall thickness, socket depth, and alignment to maintain consistency across batches.
