Underground installation conduit

Corrugated pipe QRK 40/50 FLEX blue is a reliable solution for protecting electrical and telecommunication cables laid underground. Made of durable polyethylene (PE), it provides effective protection against mechanical damage, moisture and corrosion. Thanks to its corrugated construction, the pipe is flexible and easy to route, even on complex routes. Supplied in practical coils, it facilitates installation and minimizes the risk of cable damage during pulling.

Construction and properties

The QRK 40/50 FLEX pipe is characterized by high resistance to compression - above 450N, meeting the requirements of PN-EN 61386-24:2023. The double-sealed construction provides additional protection against the effects of weather conditions and external damage. The smooth inner surface facilitates cable pulling, reducing the risk of damage. The pipe is supplied with a connector and a cable pulling cord, which significantly speeds up and simplifies the installation process. Available in blue, which helps to identify the installation.

Application and benefits

The QRK 40/50 FLEX pipe finds application in a wide range of underground installations:

• Electrical installations: protection of cables powering buildings, outdoor lighting and other electrical devices.
• Telecommunication installations: securing fiber optic and copper cables used in telecommunication networks.
• Alarm and fire protection installations: protection of alarm and fire protection system cables against mechanical damage and weather conditions.
• Cable protection in open trenches: an ideal solution for installations carried out in difficult terrain conditions.

Using the QRK 40/50 FLEX pipe guarantees long-term and safe operation of the installation, minimizing the risk of failures and costly repairs. The flexibility of the pipe allows it to be adapted to the specifics of the terrain, and its high strength provides protection against external loads.
