The concrete is compacted during the course of the radial pressing process. The pressing action is effected by the rotating pressing tool consisting of the distributor head, which rotates in the opposite direction of the pressing head. As a result, the torques of distributor head and pressing head largely cancel each other out, hence ensuring a precise and tension-free embedding of the reinforcement. The machine is controlled by a Siemens S7 electronic is PLC. The pipe production is fully automatic.
