An arcuate double-layer pipe for a pipeline for fluidic transport of abrasive solids, includes an inner pipe portion made of wear-resistant material, and an outer pipe portion of weldable steel in surrounding relationship to the inner pipe portion. A pair of coupling collars made of weldable steel is placed on opposite ends of the inner pipe portion, with each coupling collar having a ring-shaped insert of wear-resistant material and a rim-like projection so that the inner pipe portion extends between the ring-shaped inserts in the coupling collars and is overlapped on the opposite ends by the rim-like projections of the coupling collars. The rim-like projections of the coupling collars engage interiorly into opposite ends of the outer pipe portion for centering the outer pipe portion, with the opposite ends of the outer pipe portion being welded to the coupling collars.
