CPVC Schedule 40 fittings are high-performance pipe connectors made from chlorinated polyvinyl chloride (CPVC). Their primary function is to connect, redirect, divert, and control the flow of fluids with CPVC Schedule 40 pipe. Because CPVC is a chlorinated version of standard PVC, its improved temperature, pressure, and corrosion resistance enhance its performance. These fittings are particularly suitable for hot and cold water distribution and certain industrial fluid piping systems.
Product Definition and Standards
CPVC Schedule 40 fittings strictly comply with international standards such as ASTM D2466. Their dimensions and tolerances are precisely controlled, ensuring seamless connections with the same series of CPVC Schedule 40 pipe. Their wall thickness is Schedule 40, making them suitable for systems operating under medium pressure. Common sizes range from 1/2 inch to 2 inches, with some manufacturers offering custom services for larger diameters.
CPVC Schedule 40 fittings: Features and Benefits
Excellent High-Temperature Resistance
CPVC fittings can withstand long-term high-temperature operation, with a maximum operating temperature of 93°C. Compared to traditional PVC fittings, they are better suited for hot water systems.
Reliable Pressure Resistance
At room temperature, CPVC Schedule 40 fittings can withstand pressures of approximately 200 PSI (depending on the specification), meeting the needs of domestic water supply and some industrial piping.
Excellent Corrosion Resistance
CPVC is resistant to corrosion by acids, alkalis, salts, and most other chemicals, making it widely used in chemical and water treatment systems.
Sanitary Safety
The fittings comply with NSF/ANSI 61 drinking water standards, ensuring clean, odor-free fluids and suitable for drinking water systems.
Excellent Flame Retardancy
CPVC is self-extinguishing and does not support combustion, meeting building safety requirements.
Easy Installation
The fittings are installed using solvent bonding, which is simple and fast, requiring no complex tools or equipment.
Common Types
CPVC Schedule 40 fittings are available in a wide variety to meet diverse piping design requirements:
Coupling: Used to connect two pipes of the same diameter.
Elbow: Commonly available in 90° and 45° angles, used to change flow direction.
Tee: Used to branch or merge pipes.
Reducer: Used to connect pipes of different diameters.
Cap: Used to seal pipe ends.
Union: Used to facilitate disassembly and maintenance.
Threaded Fittings: Used where threaded connections are required.
Applications of CPVC Schedule 40 fittings
Residential: Hot and cold water piping, kitchen and bathroom piping.
Commercial: Water supply systems in hotels, apartments, schools, hospitals, etc.
Industrial: Low-concentration chemical transport, cooling water circulation, and purified water production lines.
Water treatment: Used in reverse osmosis equipment, filtration systems, and water purification equipment. Fire protection system: Some high-performance CPVC pipe fittings can be used in sprinkler fire protection pipelines.
Product Advantages Comparison
Compared to metal fittings (such as galvanized and copper fittings), CPVC Schedule 40 fittings offer the following distinct advantages:
Rust-resistant: They do not produce corrosion or scale, maintaining a stable flow rate.
Lightweight: They are easier to handle and install, reducing construction costs.
Cost-effective: The overall cost is lower than copper piping systems.
Long service life: In a suitable environment, they can last over 50 years.
Easy maintenance: They require no frequent replacement or maintenance, making them economical and practical.
Packaging and Shipping
CPVC Schedule 40 fittings are typically packaged in cartons or plastic bags with shock-absorbing exterior protection. Each model is clearly labeled for easy sorting and handling. Their lightweight material reduces shipping costs and the risk of damage during handling.
As a vital component of modern piping systems, CPVC Schedule 40 fittings are widely used in residential, commercial, and industrial settings due to their excellent resistance to high temperatures, pressures, and corrosion. They not only ensure the safety and stability of piping systems, but also offer an ideal alternative to traditional metal fittings due to their ease of installation and long service life. For users who need cost-effective, safe and reliable piping solutions, CPVC schedule 40 fittings are undoubtedly a trustworthy product.
