| 摘要 |
The present invention relates to a pipe length having a pressure measuring point, in particular for pressures of between 100 and 1000 bar and media which can attack or encrust the inner wall of the pipe length. It is proposed to provide a pipe length with an inner wall (1) which serves as a seal and as a wearing part and is made from an elastic material. The inner wall (1) is surrounded on a segment by a metallic cylindrical ring (10) whose wall strength is dimensioned such that said ring is elastically deformed when the internal pressure to be measured is applied to the pipe length. The cylindrical ring (10) has one or more measuring devices (15, 16) preferably strain gauges, for measuring its deformation. The inner wall (1) or cylindrical ring (10) with measuring devices (15, 16) are surrounded by a housing (4, 7, 12) which absorbs all external forces and, apart from in the region of the cylindrical ring (10), the internal pressure, but does not prevent the expansions of the cylindrical ring (10). The pipe length is provided at both ends with connecting flanges (5, 8). <IMAGE>
