RCC Hume Pipe

A hume pipe is a concrete tube with reinforced bar. It was invented by the Hume brothers in Australia in 1910. A hume pipe is formed by pouring concrete into a form work, and axially rotating it, and allowing it to compact using centrifugal force.Reinforced cement concrete spun pipes upto 1000 mm dia are exclusively reserved for manufacture in the SSI sector. These pipes are widely used for water drainage, sewerage, culverts and irrigation. RCC pipes are classified as pressure and non pressure pipes viz.Hume pipes are available in three grades NP2, NP3, and NP4. Hume Pipe is also known as Spun Pipe as it is manufactured while spinning the cage at the time of pouring concrete. In HUME pipe manufacturing process, feeding of the concrete is done manually and cages are prepared and fitted into the mould as per the size of the Pipe.Non-Pressure RCC Hume pipes of class 2 are known as light-duty Hume pipes used for sewers, irrigation, and light traffic culverts. their thickness varies from 25 to 110 mm for 8cm dia and 2.2m dia respectively.
