RCC HUME PIPES
(CODE NO.4223)
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, 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 is 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.
RCC Hume pipes are used for sewer, road, highway, culvert, irrigation and water supply. Hume Pipe or Spun Pipes are available in 3 classes, normally NP2 and NP3 are manufactured using the HUME pipe manufacturing machines. But heavy duty pipes NP4 are produced using vertical manufacturing process, which is most advanced and computerized system.
Hume pipes manufacturing in India entirely depends on the construction market, which has been booming for last two decades due to enormous growth in construction, infrastructure and power sector in India.
RCC or Pre cast Pipe is the major civil engineering achievement. The HUME Pipe process for manufacturing the Reinforcement cement is a conventional system, where concrete is being poured manually after preparing the Reinforcement cage.
