Wavin developing an underground plastic pipes ventilation system

Wavin Underground Plastics Pipe Installation System

Wavin Norway with its stellar reputation helped it to fetch a dynamic and new project of an underground ventilation. The project of installation of an Underground Ventilation System (UVS) in a school in Kongsberg was assigned to Wavin as  Werner Overland, Site Manager at Skorve Entrepreneur AS could easily think of Wavin since he had a good experience previously.

Werner asked Wavin to deliver DN 1800 pipes as ventilation pipes for installation in the ground. This was for the installation of a plastic pipeline from the outside intake/exhaust towers, which would provide air into the aggregates placed in a technical room in the basement.

The concept of an underground ventilation system (UVS) finally became a reality. The drawings and calculations were approved by the contractor and consultants.  With this customized UVS, both the intake and exhaust are taken into the building via a “manifold pipe” where 5 Wavin DN1000s connect the outside trenched DN1800 pipe with the technical room inside. All parties were delighted that everything fit perfectly and the installation went very smoothly.

Wavin DN1800 pipes are made as long as possible transport-wise – with lengths up to 16,5 meters. They are gigantic. The whole system is welded on site, and this is made easy with the integrated electrofusion sockets on the XL pipes – an additional option on Wavin’s standard pipes. Welding secures the tensile strength and ensures that there are absolutely no air leakages.

The uses of plastic pipes are countless. Also, there is immense untapped potential in such kinds of projects. The greatest benefit of using plastic pipes for such an application is longevity. Wavin DN1800 pipes have demonstrated a longer life span by eliminating weldtear and delamination. In this aforementioned school project, the system was used in a new construction. However, an underground ventilation system can also be used in the renovation of existing buildings.
