J-tubes and S-tubes
J-tubes and S-tubes protect cables against the enormous power of the sea. These tubilars are essential to lead cables from the foundation to the top part of the offshore substation or windmill.
As the name indicates, the steel tubes are formed into a J or an S shape. Kersten bends these tubes (small radii) with the latest generation of bending machines. For large tubes, we use Europe's largest roll bending machine, which bends tubes up to Ø610 mm with a thickness of up to 40 millimetres.
For even larger pipes we make use of an advanced induction bending machine. For bending tubes and pipes up to 914mm.
As well as producing J-tubes and S-tubes, Kersten also produces bellmouths.
