Double-wall corrugated pipe fittings and inspection wells
"Pipe fittings" mainly address the connection issues between pipes, as well as the requirements for direction changes and branching. The most common connection method for double-wall corrugated pipes is the socket-type flexible connection, so the core pipe fittings are also designed around this.
The socket and plug connection is achieved using rubber sealing rings. This method offers excellent sealing performance, can accommodate small angular deviations and axial displacements, has strong anti-knock capabilities, and is fast to install. It is currently the most popular connection method.
HDPE double wall corrugated pipes are designed with a corrugated outer wall for high ring stiffness and a smooth inner wall for excellent hydraulic performance. To ensure a flexible and continuous pipeline layout, a full range of HDPE fittings is available, including couplers, bends, tees, reducers, and end caps.
These fittings are typically connected by socket-and-spigot joints with rubber ring sealing, providing strong leak resistance and allowing the pipeline to accommodate minor ground settlement. Compared with rigid pipe systems, HDPE fittings significantly reduce the risk of joint failure and long-term leakage.
Plastic inspection chambers are an essential part of HDPE drainage systems. Installed at pipe intersections, direction changes, diameter transitions, and regular intervals along straight sections, inspection chambers allow easy access for inspection, cleaning, and maintenance.
Manufactured from HDPE or PP materials, plastic inspection chambers are lightweight, corrosion-resistant, and compatible with HDPE corrugated pipes through flexible connectors. They are increasingly replacing traditional concrete manholes due to faster installation, better sealing performance, and lower maintenance requirements.
