Pipe connection of fibre reinforced plastic pipe parts

Abstract

Abstract A pipe connection of a first and a second fibre reinforced plastic pipe by accommodating a free end portion of each pipe in a centering plastic pipe part, an adhesive layer being present between the inner side of the centering pipe part and the outer side of the free end portions. A reinforcing layer extends over the centering pipe part and over parts of the first and second pipe part adjoining the free ends of the centering pipe part, preferably the centering pipe part has a smaller wall thickness than the wall thickness of the first and second pipe parts. The free end portions have a smaller wall thickness than the wall thickness of the centering pipe part. The centering pipe part may be formed as a bend, or part of a saddle or branch saddle and consists of a reinforced thermosetting plastic material. The bend may be formed from a plurality of standard bend parts of relatively small length, e.g. 5° or 10°, each having an end widening and a bend part end portion of a consecutive bend part penetrating into said widened end, an adhesive layer engaging said penetrating bend part end portion and the opposite inner wall of the widening. The fibre reinforced plastic pipes, the centering pipe part and the reinforcing layer all consist of thermosetting resin.
