To increase lifetime and reduce maintenance costs to structural elements within the wind industry TP-Products have developed a tower flange which will solve the following problems among others:
- Fatigue in bolts
- Local bending of bolts
- Loose nuts due to vibrations and dynamic loads
- Bolt corrosion
What distinguishes TP-Products’ bolted flanges from the traditional bolted flanges is that we are looking at bolts and flanges as a system where the flange design is made such that most of the forces pass through the flange surfaces and the bolts are thereby exposed to very low dynamic forces. They will not loose and the coupling stays tight, which again results in no need for bolt tightening and less corrosion. What we also see, is that our flange design reduces welding problems.
