HDPE Drinking Water Supply Pipes from China Factory - Durable, Corrosion-Resistant, and Reliable Suppliers
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 / Micro-sprinkler
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
Does the HDPE coil pipe meet drinking water safety standards?
Yes, it fully complies with the GB/T 17219 drinking water hygiene standard. It is non-toxic and free of heavy metal additives, preventing secondary water pollution.
What are the available diameter specifications for these pipes?
Common specifications include diameters of DN20, DN25, DN32, DN40, DN50, and DN63.
What is the standard length of a pipe coil?
The standard length is usually 200 meters per coil, but it can be customized based on your project requirements.
What is the working temperature range for the HDPE coil?
The standard applicable temperature range is -20℃ to 40℃. However, certain specialized HDPE models can operate in temperatures ranging from -60℃ to 60℃.
How should pipes with a diameter of DN≤63mm be connected?
For diameters of DN≤63mm, it is recommended to use a hot-melt socket or electrofusion connection to ensure a completely sealed and secure interface.
What is the difference between black and white HDPE pipes?
Black pipes contain carbon black, which provides excellent UV resistance. White pipes are made from natural color materials.
