R.C.C. SPUN PIPES (VIBRATED CAST PIPE)

       Rainforced cement concrete (R. C. C.) pipes Popularly known as “Hume pipes” was discovered by “sir waltes hume at Australia. These pipes are produced by Centrifugal spinning  process.  The Hume pipes were  introduced in India with  the  help  of  ‘Abet brothers’ by the name “The Indian Hume Pipe Co. Ltd.” As early as 1926.

Today there are tremendous private R.C.C.  pipes factories throughout India even in remote area too.

One of such factory is everest spun pipe Industries, started in 1979-80 under small scale Industries.

The proprator shri. Namdev K. Jagtap at first was a pipe jointer who started undertaking contracts works since 1966.  He completed  more then 86 lift irrigation schomes  throughout  Pune district  from 1950 tp 1093 the firm successfully completed  more than  100  lift irrigation schemes on tuzkey bases and  they  are still working successfully without and leakage or damage.

RCC/Hume  pipes  are made of a mixture of  portland  cement, sand and aggregate in the proportion of 1:2:5:2.5 with steel rods and   wires   as  reinforcement  material. These   pipes   are manufactured in diameters ranging from 300 mm to 2200 mm or more.   The RCC pipes are suitable for irrigation, culvert construction, and sewerage and drainage purposes.   Transportation  of   water, sewerage,  effluents or other liquid slurries in these  pipes  is quite  smooth.  Seepage or leakage is totally avoided by proper jointing  & sealing of two consecutive pieces of the  pipe  line.  Hume pipes have reasonably good load-bearing capacity, and hence, can be laid either underground or over the  ground.   Carefully made pipes, tested as per IS : 458-1971, are available in a  wide range of sizes for use.  Well constructed steel wire/rod cage  is concentrically  placed  inside  the  pipe  mould  where  premixed concrete  is  charged  for pipe  casting.   The rotating moulds receive the feed material through open ends at both ends.

This  project  proposes to manufacture RCC/hume pipes  in  a range  of diameters and 1.8 m & 2.8 m lengths which are  in  very common use.
