Abstract (en)
[origin: DE10008688C1] The mechanical pipe expander is a multi-edged pyramid with segments on the mantle surfaces, which are moved radially by an axial movement of the pyramid in relation to them. A lubricant cladding (5) is between the mantle surfaces of the pyramid (2) and the segments (3). The lubricant cladding (5) is a compound carbon fiber material with a polymer matrix containing graphite powder.

Die Erfindung betrifft einen mechanischen Rohrexpander mit einem pyramidischen Vielkant (2) und auf dessen Mantelflächen angeordneten Segmenten (3), die durch eine axiale Verschiebung des Vielkantes (2) relativ zu den Segmenten (3) radial bewegbar sind. Zwischen den Mantelflächen des Vielkantes (2) und den Segmenten (3) ist ein Verschleißbelag (5) angeordnet. <IMAGE>
