HDPE pipes ( high density polyethylene pipes ) and fittings

Our HDPE pipes are engineered for 50+ years of leak-free, maintenance-free service. Made from 100% virgin PE100/PE4710/PE100-RC, they suit water, gas, mining, sewer, fire, dredge, municipal, and industrial use. Available in 20–1800mm diameters, PN6–PN32, and SDR26–SDR6. Certified by FM, NSF, WRAS, BV, AENOR, CE, and ISO.

✨ Key Advantages of HDPE Piping Systems:

• ️ High Toughness – Elongation at break ≥500%, excellent adaptability to uneven foundation settlement.

•  Excellent Coilability – Allows long-length coiled supply, reducing the need for extra joints.

•  Outstanding Crack Resistance – Low notch sensitivity, high shear strength, and superior resistance to environmental stress cracking.

• ⚡ Rapid Crack Propagation Resistance – Effectively prevents sudden pipeline failure during operation.

•  Easy Installation – Lightweight construction simplifies handling, reduces labor and lifting equipment costs, and boosts overall efficiency.

•  Superior Flow Performance – High wear resistance, non-stick surface, and corrosion resistance keep the bore smooth; flow capacity exceeds steel pipes by over 50%, ensuring long-term low-pressure, unimpeded operation.

We provide the HDPE pipes from dn20mm to 1800mm.

Features of HDPE pipes and fittings

• Green environmental protection: HDPE pipe non-toxic, tasteless, after strict health monitoring, belongs to green building materials, never scale, can effectively improve water quality.
• Corrosion resistance: HDPE pipelines are resistant to corrosion by a variety of chemical media, and chemicals present in the soil do not cause any degradation to the pipeline.
• No leakage: The polyethylene pipe system is connected by electrofusion and butt fusion methods, and the strength of the joint is higher than the strength of the pipes.
• High toughness: The elongation at break of HDPE pipes is generally above 500%. For the uneven settlement of the foundation engineering construction, its adaptability is very strong and the seismic performance is good. HDPE was the only pipeline system that survived the 1995 kobe earthquake in Japan.
• Crack resistance: Rapid Crack Propagation (RCP) for polyethylene plastic piping systems.
• Good wear resistance: Good wear resistance, low wall friction coefficient, low flow resistance and strong conveying capacity.
• Excellent flexibility: HDPE pipe can be used in a variety of trenchless ways, easy to construction and installation.
• Low cost: Low system cost and low maintenance cost can greatly reduce project costs.
• Long service life: The buried HDPE pipe is normally used for 70 years.
• Recyclable, environmentally friendly: HDPE materials can be reused, fully in line with the nationally advocated efficient environmental protection concept.
