White HDPE Tube PE Pipe Customize PE Tube
HDPE pipe is a plastic pipe made primarily from high-density polyethylene (HDPE) resin through an extrusion process. HDPE is the highest-density, most densely packed polyethylene (PE) material. It boasts a high crystallinity (60%-80%), excellent chemical stability, flexibility, and resistance to environmental stress cracking. Pipes made from HDPE perfectly inherit these properties, making it a core pipe material for municipal engineering, industrial transportation, agricultural irrigation, and other fields worldwide.
Compared to traditional metal pipes (such as steel and cast iron), cement pipes, or ordinary plastic pipes (such as PVC), HDPE pipe offers the advantages of corrosion resistance, flexibility, impact resistance, long life, and ease of installation. It is widely used in water supply, gas, sewage, chemical fluid transportation, agricultural irrigation, and other applications, representing the "plastic-to-steel" alternative in modern piping systems.
Typical Application Scenarios and Application Areas
1. Municipal Engineering
Water Supply Pipelines: Urban/Rural Tap Water Distribution (Replacing Traditional Cast Iron and PVC Pipes, with a Lifespan of Over 50 Years), Residential Secondary Water Supply Networks (Sanitary and Safe, No Secondary Pollution);
Gas Pipelines: Low-Pressure Natural Gas/Coal Gas Distribution (Yellow HDPE Pipes, Compliant with GB 15558.1 Standard for Buried Polyethylene Pipes for Gas, Corrosion-Resistant, Flexible, and Earthquake-Resistant);
Sewage Pipelines: Municipal Sewage Networks (Sewage-Resistant, Smooth Interior to Reduce Clogging), Stormwater Pipes (Impact-Resistant, Suitable for Heavy Rainfall).
2. Industrial Sector
Chemical Fluid Transportation: Transportation of Acids and Alkali Solutions (e.g., Factory Wastewater Treatment, Laboratory Pharmaceutical Pipelines), Oils (e.g., Lubricant Distribution), and Organic Solvents (Modified HDPE must be selected based on the medium);
Industrial Cooling Water Systems: Factory Circulating Water Pipes (Scale-Resistant, Long-Term Flow Stability).
3. Agriculture and Water Conservancy
Irrigation Pipes: Main and branch pipes for drip/sprinkler systems (resistant to pesticide corrosion, flexible and easy to lay, adaptable to undulating field terrain), greenhouse water pipes (resistant to UV aging);
Rural Drinking Water Safety Projects: Replace traditional cement/iron pipes to address the issues of pipe corrosion and deteriorating water quality in rural areas.
4. Special Environments
Submarine/Lake Water Pipes: Corrosion-resistant and flexible (can be transported on reels and welded and laid on-site), suitable for cross-sea drinking water projects or lake water diversion projects;
Pipes for Frozen Soils: Resistant to cracking at low temperatures, suitable for underground installation in high-altitude and cold regions (such as Northeast China and the Qinghai-Tibet Plateau).
Summary:
- HDPE pipe: Prioritizes corrosion resistance, underground installation, long lifespan, and flexibility for anti-settling applications (such as municipal water supply and drainage, gas, and agricultural irrigation).
- PVC pipe: Suitable for low-cost, non-potable water, and normal-temperature drainage (such as building drainage pipes, but not resistant to high temperatures or chemical corrosion).
- PPR pipe: Suitable for hot water supply within buildings (≤95°C) (hygienic and heat-resistant, but less flexible).
- Steel pipe: Only suitable for high-pressure, high-temperature, or specialized industrial fluids (such as oil transportation), but requires additional corrosion protection.
