Manufacturing Process

  1. Cages/reinforcement/jali are made as per IS:458.
  2. Mould release agent is properly applied inside the mould, and reinforcement is placed inside the mould, assembled with end-rings & tie-rod.
  3. Assembled moulds are placed on the spinning machine with the help of Chain-pulley or Electric Hoist.
  4. Concrete is mixed in the mixture machine as per the mix design and is placed at both ends of the mould opening.
  5. Initially, the spinning machine is started at low RPM, and concrete is poured inside the mould from both ends. RPM is controlled with the help of gearbox, reaves gears, or VFD.
  6. Due to centrifugal force, concrete is evenly distributed inside the mould, and extra water is squeezed out, resulting in a very dense, waterproof, and strong pipe.
  7. After the inside finishing of pipes, they are set aside for curing. Generally, it takes 24 hours to set the concrete.
  8. After ensuring proper setting, the moulds are opened, and pipes are put for curing.
  9. Pipes are cured for 7-21 days, and then siding is done. After this, the pipes are ready for dispatch.

Testing

  1. Testing of Concrete Pipes is done as per IS:3597.
  2. We have facilities for Three Edge bearing testing, Straightness Test, and Dimension Test.
