摘要： A pipe connection, in particular an electrically insulating pipe connection, formed by interlocking or interpenetration of material between (a) an overlapping, reinforced plastic pipe which is subdivided into a number of superimposed pipe shells or pipe layers which have a flange at right angles to the axis of the pipe at their ends and which are advantageously separated from each other and can therefore be deformed independently in the axial direction of the pipe, and (b) at least one pipe, preferably overlapped by the pipe shells or layers and made, in particular, of metal. The end of the plastic pipe is wound, pressed or cast around the end of the overlapped pipe, and the flanges of the innermost pipe shell or layer hooks onto a shoulder at each end of the overlapped pipe. The end region of the outermost pipe shell or layer may be enclosed by a coupling ring. The flanges (1'-10') of the pipe shells (1-10) or pipe layers abut on each other, possibly via an incorporated ring (20) or ring winding preferably perpendicular to the axis of the pipe. Said ring or ring winding has a projection (21), for example, which is arranged between the adjacent axial surfaces of adjacent pipe shells (7, 8; 9, 10) or pipe layers, but is preferably fixed to only one of these pipe shells (7; 8; 9;10).
