A characteristic feature of the present invention is the fact that the pipe producing plant has a horizontal platform rotatable round a vertical axis, on which a mould with conduit formers for pipe making is located. The base of the plant mounts a mechanism for feeding, tensioning of the reinforcement wire and wounding it onto a moulded pipe, and bench carrying a mechanism for filling the mould with concrete mix, a mechanism for smoothing the pipe end face and a mechanism for placing a protective cement mortar cover upon the reinforcing wire wound onto the moulded pipe. The plant incorporates also a mechanical actuator for alternatively raising and lowering the conduit formers, said actuator being mounted on a rigid base outside the rotary platform.
