ABSTRACT:
A connection of steel pipes for conveying solid materials, particularly for conveying gravel, includes radially directed coupling flanges which extend circumferentially at the ends of the steel pipes. The coupling flanges have receiving bores for the coupling bolts, wherein the receiving bores extend parallel to the longitudinal axes of the steel pipes and are arranged on a pitch circle. At least one wear ring is inserted between the end faces of the steel pipes which face each other. The wear ring is of a material which has a greater resistance to wear than the material of the steel pipes.
