| HDPE Reducers | Connects two pipes of different diameters to adjust flow capacity. | Used where different parts of the system require varying pressure or flow rates. | 400 – 1,611 |
| HDPE Compression Fittings | Offers a simple and fast method for joining HDPE pipes without welding. | Includes compression elbows, tees, and couplers. | Varies based on fitting |
| HDPE Saddles | Creates outlets from the main HDPE pipe to supply secondary pipes or branch lines. | Ideal for drip irrigation or sprinkler systems. | 400 – 2,500 |
| HDPE Ball Valves | Regulates water flow in the irrigation system. Allows for stopping or adjusting water flow without disrupting the entire system. | Common for water management and system maintenance. | 1,900 – 5,500 |
| HDPE Flanges | Connects HDPE pipes to other systems, machinery, or fittings for a strong, leak-proof connection. | Ideal for high-pressure systems or where pipes connect to pumps/filters. | Varies |
| HDPE Stub Ends | Used in conjunction with flanges to create a detachable connection, ideal for systems needing frequent disconnection for maintenance. | Common in pipelines requiring regular modifications or inspections. | Varies |
| HDPE Electro-Fusion Fittings | Fitted with electrical heating elements to create a seamless bond between pipes. Superior strength and leak resistance. | Electrofusion couplers, reducers, elbows, and tees are available. | Varies |
| HDPE Repair Clamps | Fixes leaks or cracks in HDPE pipes without needing to cut or replace sections, offering a temporary or permanent solution to damaged irrigation pipes. | Reduces downtime and repair costs. | Varies |
Applications of HDPE Fittings in Kenya
HDPE fittings are widely used in various irrigation systems, including:
- Drip Irrigation: For precise water delivery to plants, HDPE fittings such as saddles and tees are critical.
- Sprinkler Systems: These fittings ensure even water distribution across large areas.
- Piping Networks: HDPE couplers and elbows help create extensive piping networks for efficient water distribution on farms.
Benefits of Using HDPE Fittings for Irrigation
- Leak-Free Connections: HDPE fittings are designed for optimal sealing, minimizing water wastage and ensuring efficient water distribution.
- Corrosion Resistance: Unlike metal fittings, HDPE is resistant to corrosion, making it ideal for agricultural use in different soil types and water conditions.
- Longevity: HDPE fittings have a long service life, reducing maintenance costs and system downtime.
- Easy Installation: HDPE fittings, especially compression fittings, are easy to install, reducing the complexity of the irrigation setup.
FAQ
What are HDPE pipe fittings used for in irrigation systems?
