The installation comprises two centrifugal casting moulds which are roughly parallel to each other and are movable by rotation of a common support between a mould preparing station, a pouring station and a pipe extracting station, which stations are disposed in such maner that one of the moulds is in the axial extension of the pouring station when the other mould is in the axial extension of the extracting station and vice-versa. The two moulds are carried by rollers mounted on the common support and the latter comprises a horizontal platform which is rotatable about a central vertical axis relative to which the two moulds are symmetrically arranged.
