pipelines from DN300
to 600 over 1.6 km
Our proposal: run two pipelines through the same duct, using threading collars designed by our teams. In view of the confined spaces involved, custom-made collars are fixed to the fifth pipe so that it can slide along the 4th, already in place.
Advantages: cost savings – no need for an additional micro-tunneler – with no impact on the work schedule.
