HDPE Siphon Drainage Pipe

PE pipe

HDPE Siphon Drainage Pipe

HDPE siphon drainage pipes are designed for roof siphon rainwater systems, using negative pressure generated by building height differences to achieve full-bore drainage with high efficiency. The suspended pipes need no slope and can be laid horizontally, reducing the number of risers and saving building space. Tough, corrosion-resistant and ageing-resistant, they use heat-fused joints for stable sealing. Widely used for flat roof rainwater drainage in factories, shopping malls and residential buildings.

Features

  • UV and ageing resistant, with a service life of up to 50 years.
  • Smooth inner wall with low friction resistance.
  • About 30% lower pressure loss than steel pipes, allowing smaller pipe diameters.
  • Hygienic: no additives and no water contamination; PE offers strong mould resistance for long-term use.
  • Can be welded into a complete, reliably sealed system.

Applications

  • Factory roof rainwater drainage
  • Shopping mall flat roof drainage
  • Residential siphon rainwater systems

HDPE Gas Pipe

HDPE Gas Pipe

PE gas pipes are produced from dedicated high-density polyethylene material with excellent resistance to slow crack growth and corrosion, remaining stable in acidic or alkaline soil. Their toughness and impact resistance, combined with fusion joints that form a continuous body, greatly reduce the risk of gas leakage. Lightweight and coilable for easy transport and installation, they are mainly used for urban medium and low pressure buried gas transmission, offering high safety for city gas renovation projects.

HDPE Double-wall Corrugated Pipe

HDPE Double-wall Corrugated Pipe

HDPE double-wall corrugated pipes are made of high-density polyethylene for sewage and drainage. The corrugated outer wall provides high ring stiffness and compressive strength, while the smooth inner wall ensures low flow resistance and large capacity. Rubber-ring socket joints give reliable sealing, and the pipes are corrosion-resistant, lightweight and easy to install. Widely used in municipal stormwater/sewage separation, residential drainage and river discharge projects.
