ABSTRACT:
The connector pipe segment for conductor pipes or conduits for gaseous as well as fluid flow media comprises a pressure-tight outer shell, at least two connector pieces, a plurality of sealing surfaces and a wear-resistant sleeve, advantageously of a sintered ceramic material. The wear-resistant sleeve is inserted in the outer shell and the sealing surfaces are located on the outer shell. The wear-resistant sleeve is inserted with radial play and with axial play free of force in the outer shell so that a gap is formed between the outer shell and the wear-resistant sleeve. The gap is connected with the open cross section of the wear-resistant sleeve and admits the flow media.
