Innovative Double-Wall Structure

Innovative "annular corrugated outer wall + smooth inner wall" design. Outer wall enhances pressure resistance for complex buried environments; smooth inner wall (roughness coefficient 0.009) ensures smooth water flow, ideal for municipal drainage and agricultural irrigation.

Excellent Temperature Resistance

Stable operation at -60℃~60℃, adapting to extreme climates (severe cold/high temperature) without performance degradation, ensuring stable use in different regions

Long Service Life

50-year service life under buried conditions (no UV exposure), reducing long-term operation and maintenance costs for municipal and agricultural projects.

Durable & Environmentally Adaptive

Resists soil corrosion, acid-base erosion and electrical interference, non-toxic and non-scaling. Flexible to adapt to slight ground settlement, impact-resistant to ensure pipeline integrity.

Reliable Sealing

Rubber seal ring connection ensures excellent water tightness. Lightweight HDPE for easy handling and fast installation, shortening construction period and reducing labor costs.

Eco-Friendly & Cost-Effective

Smooth inner wall reduces dredging costs; recyclable and eco-friendly. More cost-effective than concrete/cast iron pipes, saving raw materials with obvious price advantages.

Strict Quality Control& Flexible Specs

Strict quality control throughout production; each batch inspected before delivery. Customizable specifications (DN200mm-DN600mm and special sizes) for personalized project needs.

What are the common specifications of Jianlong HDPE double-wall corrugated pipe for municipal drainage and agricultural irrigation?

Common inner diameter specifications of Jianlong HDPE double-wall corrugated pipe include DN200mm, DN300mm, DN400mm, DN500mm, DN600mm, etc. The conventional factory length is 6 meters, which can be customized according to the needs of municipal drainage, agricultural irrigation and other projects that use HDPE double-wall corrugated pipe.

What are the connection methods of Jianlong HDPE double-wall corrugated pipe for industrial and municipal use?

The most commonly used connection method for Jianlong HDPE double-wall corrugated pipe is socket-type rubber ring connection. One end is a socket with a sealed rubber ring, and the other end is a spigot. Insert the spigot into the socket to make the rubber ring elastically compress to form a seal. For large-scale municipal or industrial projects, heat shrinkable tape connection can also be adopted for Jianlong HDPE double-wall corrugated pipe according to engineering needs.

What should be noted during the installation of Jianlong HDPE double-wall corrugated pipe for agricultural irrigation and municipal drainage?

When installing Jianlong HDPE double-wall corrugated pipe for agricultural irrigation and municipal drainage, first, the spigot should be installed along the direction of water flow, and the socket should be against the direction of water flow. Second, the cut pipe mouth of the HDPE double-wall corrugated pipe should be vertical and flat. Third, before connection, the inner and outer surfaces of the socket and spigot of the Jianlong HDPE double-wall corrugated pipe should be cleaned, and the integrity and correct installation of the rubber ring should be checked. Fourth, the axis of the spigot must be aligned with the axis of the socket to avoid deviation, ensuring the stable operation of the HDPE double-wall corrugated pipe system.
