Corrugated Pipes
Corrugated pipe is a type of polyethylene pipe that, due to its special structure, has high resistance to pressure and impact. These pipes consist of two layers: a smooth inner layer and a corrugated outer layer. The corrugated outer layer increases the pipe’s resistance to pressure and impact.
Technical characteristics of corrugated pipe
- High resistance to pressure, impact and external loads
- Resistance to corrosion and chemicals
- Light weight compared to single-layer polyethylene pipe
- Easy installation
- Reasonable cost
- Long lifespan
- Non-sedimentation due to the smoothness of the inner surface of the pipe
- Resistant to temperatures up to 50 degrees Celsius
- Resistant to the sun’s ultraviolet rays
Corrugated Pipe Applications
Corrugated pipes are used in various cases, including the following:
- Wastewater transfer
- Surface water collection
- Drainage
- Transmission of electrical and telecommunications cables
- As a protective tube
Installation and execution of corrugated pipe
Installation and execution of corrugated pipes must be carried out in accordance with the manufacturer’s instructions and relevant standards. In general, the installation of these pipes includes the following steps:
- Bed preparation
- Placing the pipes in the bed
- Connecting pipes to each other
- Filling around pipes
- Corrugated pipe
Standards
Corrugated pipes are manufactured in accordance with various standards, including the following standards:
- INSO 9116-1 standard
- INSO 9116-2 standard
- INSO 9116-3 standard
- DIN 16961-1 standard
