High-Quality HDPE Drinking Water Pipe Coils from China Suppliers - Durable & Long-Lasting Factory Solutions
Product Features
1. Hygiene and safety
It complies with the GB/T 17219 drinking water hygiene standard, is non-toxic and free of heavy metal additives, avoiding secondary pollution.
2. Flexible and convenient
The coil design is convenient for transportation and laying, and is especially suitable for small-diameter (DN20-DN63) terminal water supply or decentralized irrigation.
3. Corrosion & Low-temperature Resistance
Resistant to chemical medium corrosion, applicable temperature range: -20℃ to 40℃ (some HDPE models can be extended to -60℃ to 60℃).
Main Application Scenarios
Household & Community Water Supply
Terminal drinking water delivery, such as household water purification systems and direct drinking water pipelines in residential areas.
Agricultural Drip Irrigation
Small-diameter coils are suitable for drip irrigation tape branches or greenhouse micro-sprinkler systems.
Emergency Water Supply
Rapidly deployed temporary drinking water pipelines (such as in disaster relief scenarios).
Key Points for Selection and Construction
1. Material selection
HDPE (PE100 grade) is preferred as it features high strength and excellent pressure resistance (up to 1.6MPa).
2. Quality identification
Check that the appearance is smooth without bubbles and the color is uniform (black contains carbon black for UV resistance, and white is the natural color material).
3. Connection method
For DN≤63mm, hot-melt socket or electrofusion connection is adopted to ensure the sealing of the interface.
Common specifications
Frequently Asked Questions (FAQ)
Do these pipes comply with drinking water safety standards?
Yes, they comply with the GB/T 17219 drinking water hygiene standard. They are completely non-toxic and free of heavy metal additives to prevent secondary pollution.
What are the recommended application temperatures for these coils?
The standard applicable temperature range is -20℃ to 40℃. However, specific HDPE models can extend this range to between -60℃ and 60℃.
What connection methods should be used for small diameters?
For diameters DN≤63mm, either a hot-melt socket or electrofusion connection is recommended to ensure a secure, leak-proof interface.
Why are some pipes black while others are white?
Black pipes contain carbon black, which provides excellent UV resistance. White pipes are made from the natural color material without color additives.
What is the standard length of a pipe coil?
The standard coil length is 200 meters per coil, but this can be customized to meet specific project requirements.
Which material grade is preferred for high-pressure applications?
HDPE (PE100 grade) is preferred for high-pressure setups due to its high strength and pressure resistance of up to 1.6MPa.
