ABSTRACT:
A flange connection of pipe pieces having an outer layer composed of a laminate and provided with grooves. A two-part sleeved collar of the same material is radially placed onto the pipe piece. Projections provided on the radially inner surface of the flanged sleeve are placed in the grooves. The two parts of the flanged sleeve are fixedly connected to the pipe pieces by means of gluing, the two parts of the flanged sleeve being held together until the adhesive has cured by means of a flange ring slid onto a conical portion of the flanged sleeve. A cover ring is fastened to the end of the inner layer of the pipe piece made of a thermoplastic material, so that the medium conducted through the pipes does not come into contact with the couter layer and the flanged sleeve.
