Abstract
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.

Claim 1
Independent Claim
134 words
In a connector pipe segment for conductor pipes or conduits for gaseous as well as fluid flow media comprising a pressure-tight outer shell, at least two connector pieces, a plurality of end face sealing surfaces and a wear-resistant sleeve, said wear-resistant sleeve being inserted in said outer shell, the improvement wherein said sealing surfaces are located only on said outer shell and said wear-resistant sleeve is inserted with radial play and with axial play free of force in said outer shell so that a gap is formed between said outer shell and said wear-resistant sleeve, said gap being connected with the open cross section of said wear-resistant sleeve and admitting said flow media, said outer shell being a pressure-tight metal connector body which is provided on an inner surface with a corrosion resistant layer.
