Flexible pipe part i.e. decoupling element, for e.g. transformer oil pipe of vehicle, has braided fabric fixed at first board of metal bellow with end, while braided fabric does not comprise connection with second board

摘要

The pipe part has an annularly or helically curved metal bellow (1) with first and second cylindrical indication boards (3, 4) for attaching the bellow at upstream and downstream pipes. A tubular braided fabric (2) is made of metal wires or metal wire bundles, and wrapped outside the bellow. The braided fabric is fixed at the first board with an end (6) of the braided fabric, while the braided fabric does not comprise a connection with the second board. Another end (7) of the braided fabric is provided with a final casing (9) or a taper.
