This machine utilizes the roller pressure and centrifugal force generat-ed by the rotation of the suspended roller shaft and steel mold to compact and shape the material. It can produce reinforced concrete drainagepipes with an inner diameter of 300-2600m and a length of 1000-4000mmor less, The formed pipes can then be made to reach standard strengththrough steam or natural curing, with an average efficiency of 6-8 sections/hour. The machine is easy to operate, runs smoothly, is reliableand durable, and has a lo failure rate.
