INTRODUCTION
Reinforced Cement Concrete (RCC) Spun / Hume Pipes are generally used for water
drainage,sewerage,culverts and irrigation. RCC Pipes are very much preferred for such
usage because they are leak proof, are easily repairable and are non‐reactive to
sewerage toxins. Concrete Pipes has been estimated to easily last around 100 years and
as such they are fit and forget solution which is why they are preferred over other
materials for such usage.
Reinforced cement concrete spun pipes upto 1000 mm dia are exclusively reserved for
manufacture in the MSME sector.
RCC Spun Pipes are classified as pressure and non‐pressure pipes. viz NP1, NP2, NP3,
P1, P2, P3 for use in specific conditions. RCC Hume Pipes are made from cement, coarse
and fine aggregate, sand, mild steel and HT Rods and bars.
RCC Spun/Hume Pipes have been used around the world since 1926. RCC Hume Pipe,so
called because it was developed by Sir Walter Hume from Australia in 1910.
RCC Hume Pipes (Also known as Spun Pipes) are used for sewerage, drainage, culverts,
irrigation, water supply / transportation, service lines etc.
MARKET POTENTIAL
Public Health Engineering Department, Public Works Departments, Agriculture and
Forest Department, National Highways, Environment Engineering Department,
Panchayats Municipal Corporations are the bulk consumers of RCC spun pipes. Most of
the customers are approved civil contractors who are executing the works of the
Government Department and Public Sector Undertakings. Presently government is
giving stress on rural irrigation and improving methods of water supply scheme, so the
demand for pipes is increasing.
TECHNICAL ASPECTS
PROCESS OF MANUFACTURE
Mixture: According to mix design and regular checking aggregates, water and Cement
are used by weight. Instructions are written on boards for proper mixtures. Instructions
are given to consume mixture within 30 minutes for its proper strength. IS 456 is
followed for this. The concrete mixture for the RCC spun pipe is prepared in proportion
of 1:2:5:2:5 of cement stone, metal and sand respectively
Molding: All moulds are properly cleaned from Hand Grinder after opening. Proper
supports are given for centering of cages. (If it is higher dia 2 cages are made as
