According to international standards, such as ISO 4427 and ASTM F714, the expected lifespan of HDPE pipes and fittings exceeds 50 years under normal usage conditions. While with the proper installation and usage, this lifespan can be extended, even to 80 years.
Compared with the traditional PVC and other relative material piping products, the HDPE with the below advantages, such as:
1. Material Durability
- Corrosion Resistance: High Density Polyethylene materials have excellent chemical resistance, capable of withstanding various chemicals, like acids, alkalis, and salts. They do not rust or corrode, making HDPE pipes ideal for use in groundwater and wastewater systems.
- Abrasion Resistance: HDPE pipes exhibit outstanding abrasion resistance, enduring long-term exposure to sand, water flow, and other abrasive factors.
2. Easy to Connect and Maintenance
- Connection Reliability: HDPE pipes are joined using heat fusion (socket fusion or butt fusion) or electrofusion welding, with joints often stronger than the pipe itself, which reducing the maintenance issues caused by joint leakage.
- Low Maintenance Costs: Due to the durability of HDPE pipes and fittings, their routine maintenance costs are minimal, and large-scale repairs are usually unnecessary within their lifespan.
3. Environmental Adaptability
- Weather Resistance: As per the standard requirements, we had added carbon black during the HDPE pipe fitting production, which withstand extreme temperatures and UV radiation, maintaining their performance in both hot and cold environments without becoming brittle or deformed.
- Stress Crack Resistance: HDPE pipes have strong resistance to environmental stress cracking, effectively handling prolonged mechanical stress.
These standards ensure the long-term reliability and economic benefits of HDPE pipes and fittings across various applications.
