Two-layer bracket pipe for mining shaft lines. The support plate is stabilized with side ribs. The wear-resistant inner pipe is uniformly through-hardened to 63HRC over its entire length. The outer shell is pressure-bearing. The male-female geometry of the connections centers the pipes to minimize misalignment within the pipeline. Shaft pipelines can be divided into intervals, in each of which a bracket pipe is placed. The basis for this is an accurate structural analysis.

(The figure shows only one example of a bracket pipe. The design for mining shaft lines are made only after prior examination of the technical specifications. Please contact us).
