History of Hume/Spun Pipes
Walter Reginald Hume (1873-1943) of Australia invented the process of making concrete pipes by spinning/centrifugal process in 1910.
After it inventor concrete pipes are called Hume pipe.
It was made through spinning/centrifugal process so it it also called rcc spun pipes or concrete spun pipes.
RCC Pipes are also knows by there uses and other names as follow.
- RCC Hume Pipe or Hume Pipe.
- RCC Spun Pipe or Spun Pipe.
- RCC Pipe.
- Cement Pipe or Concrete Pipe.
- Culvert Pipe.
- Sewerage Pipe or Drainage Pipe.
Uses
Following are the key areas where hume/spun pipes are used.
- Drainage
- Sewerage
- Rail/Road Culvert
- Irrigation / Water Supply
- Storm water Drain
- Water Well
- Septic Tank
- OFC / Electric / Phone Cable laying
Sizes & Class
We manufacturer pipe sizes from 100 mm to 1800 mm i/d and available in NP2 , NP3, NP3, & P1 class as per IS:458
Manufacturing Process
- Cages/reinforcement/jali are made as per IS:458
- Mould release agent is applied properly inside the mould and reinforcement are kept inside mould and are assembled with end-rings & tie-rod
- Assembled mould are place for spinning machine with help of Chain-pulley or Electric Hoist.
- Concrete is made in mixture machine as per mix design and is placed at both end of mould opening.
- Initially spinning machine started at low RPM and concrete is poured inside mould from both end. RPM is controlled with the help of gearbox, reaves gears or now a days with VFD.
- Due to centrifugal force concrete get flung evenly inside mould and extra water get squeezed resulting very dense, waterproof, strong pipe.
- After inside finishing of pipes are placed aside for setting. Generally it takes 24 hours to set the concrete.
- After ensuring proper setting mould are opened and pipes are put for curing.
- 7-21 days pipe are cured and then are siding is done. After this pipe are ready for dispatch.
Testing
- Testing of Concrete Pipe are done as per IS:3597
- We have facility of Three Edge bearing testing, Straightness Test, Dimension Test.
