UPVC (Unplasticized Polyvinyl Chloride) pipe fittings come in a wide range of sizes and types to accommodate various piping systems and applications. Below is a detailed overview of the sizes and types commonly available:
Sizes of UPVC Pipe Fitting
UPVC pipe fittings are available in a variety of sizes to match different pipe diameters. The sizes are typically measured in millimeters (mm) or inches (“), depending on regional standards.
Common Sizes:
- Small Diameter (for residential and light commercial use):
- 20 mm (½”)
- 25 mm (1″)
- 32 mm (1¼”)
- 40 mm (1½”)
- 50 mm (2″)
- Medium Diameter (for commercial and industrial use):
- 63 mm (2½”)
- 75 mm (3″)
- 90 mm (3½”)
- 110 mm (4″)
- Large Diameter (for industrial and municipal use):
- 160 mm (6″)
- 200 mm (8″)
- 250 mm (10″)
- 315 mm (12″) and larger
Types of UPVC Pipe Fittings:
UPVC fittings are designed for specific functions in piping systems. Here are the most common types:
1. Elbows
- 90° Elbow: Changes the direction of the pipe by 90 degrees.
- 45° Elbow: Changes the direction of the pipe by 45 degrees.
- Street Elbow: One end has a male thread, and the other has a female thread or socket.
2. Tees
- Equal Tee: Connects three pipes of the same diameter.
- Reducing Tee: Connects three pipes, with one or more of a different diameter.
3. Couplings
- Straight Coupling: Connects two pipes of the same diameter in a straight line.
- Reducing Coupling: Connects two pipes of different diameters.
4. Unions
- UPVC Union: Allows for easy disconnection of pipes for maintenance or repair.
5. End Caps
- UPVC End Cap: Used to close the end of a UPVC pipe.
6. Adapters
- Male Adapter: Connects a UPVC pipe to a male-threaded pipe or fitting.
- Female Adapter: Connects a UPVC pipe to a female-threaded pipe or fitting.
7. Crosses
- Equal Cross: Connects four pipes of the same diameter.
- Reducing Cross: Connects four pipes, with one or more of a different diameter.
8. Valves
- Ball Valve: Controls the flow of water through the pipe.
- Gate Valve: Used to start or stop the flow of water.
Material and Pressure Ratings:
- Pressure Ratings: UPVC fittings are available in different pressure classes, such as PN10, PN16, and PN20, indicating their maximum pressure capacity (in bars).
- Temperature Range: UPVC fittings are typically suitable for temperatures between 0°C to 60°C (32°F to 140°F), making them ideal for cold water systems and some warm water applications.
Conclusion:
UPVC pipe fittings are available in a wide variety of sizes and types to meet the needs of different piping systems, from residential plumbing to industrial applications. When selecting fittings, consider the pipe diameter, pressure rating, and specific application requirements to ensure optimal performance and longevity. Always check for compliance with relevant standards (e.g., ISO, ASTM, or DIN) to guarantee quality and safety.
