Socket Type Pipe
A socket-type pipe has an enlarged end forming a socket into which the spigot end of a similar pipe can enter to form a joint. This configuration is suitable where the project design calls for socket-and-spigot pipe connections.
RCC PIPE
Reinforced cement concrete pipes for civil infrastructure.
We manufacture quality RCC (Reinforced Cement Concrete) pipes used for water-supply schemes, drainage works, culverts and other civil-construction applications. The supplied company material describes centrifugal spinning production and testing across multiple parameters, with pipe configurations including plain type, spigot type, socket-end type, tongue-and-groove type and groove-end type.
The supplied material references IS 458:2003 and ASTM standards. Applicable standards,

Pipe configurations
Socket and barrel-type RCC pipe options.
Different joint arrangements are selected according to the pipeline design, installation method and project requirements.
Barrel Type Pipe
A barrel-type pipe has a uniform internal diameter and wall thickness along its length, with one or both ends joined using short-length collars of slightly larger diameter and compatible construction.
HUME PROCESS
Centrifugal spinning for formed concrete pipe.
Cylindrical steel moulds of specified dimensions are mounted over a mechanically revolved platform or flywheel and spun at a controlled speed. The resulting centrifugal force acts outward on concrete placed inside the mould. During rotation, the concrete is compacted and manually smoothed or levelled until it assumes the required pipe shape and wall thickness.
- Specified cylindrical steel moulds
- Controlled rotational speed
- Centrifugal compaction of concrete
- Forming and levelling to the required wall thickness
ROCLA PROCESS
Spin-moulded concrete pipe production.
The supplied company material describes the Rocla process as a spin-moulding method originally developed and patented in Australia. Concrete pipes produced using this method can be manufactured in different sizes, with accurate dimensions and high concrete compaction when the process is correctly controlled.
The material also describes the machinery as suitable for installation at permanent factory premises or temporary project sites, and notes its use in Japan, Europe and Africa.

Comparison of RCC Products
Why RCC is widely used for civil infrastructure.
The supplied company material highlights several practical advantages of reinforced and non-reinforced concrete products compared with some metallic alternatives.
Material availability
The supplied content describes the basic ingredients of RCC products as locally available materials, potentially reducing dependence on imported raw materials.
Low maintenance
Unlike metallic products that may require protection against rust and periodic painting, properly manufactured concrete products generally require less routine surface maintenance.
Suitable for coastal environments
The supplied material records successful use of RCC products in coastal areas where environmental exposure can accelerate corrosion of susceptible materials.
Practical manufacturing
The supplied content notes that RCC product fabrication can use relatively simple mechanical equipment and ordinary production skills when appropriate process controls are followed.
Design and Specification
Concrete pipe design, testing and specification requirements.
Unless specifically desired and directed otherwise by clients/customers, the supplied original material states that concrete pipes are manufactured in accordance with specifications and design laid down in the respective parts of the “Annual Book of ASTM Standards”. ASTM stands for American Society for Testing and Materials.
C14
ASTM Designation C14-82
Application: Non-reinforced concrete pipes for sewerage, storm drainage and culverts.
Pipes have been classified into three basic categories, Classes 1 to 3. Minimum strength and wall-thickness requirements for different internal diameters, ranging from 4 to 36 inches, are tabulated.
Criteria for final approval, acceptance or rejection are based on test results showing strength, absorption, permeability and hydrostatic properties of selected pipes and their visual inspection for finishing and other physical features.
Methods of sampling, marking, testing/re-testing the pipes and concrete mixing, preparation and curing are defined. Permissible strength is illustrated, and related documents applicable to related aspects are identified.
C76
ASTM Designation C76-82b
Metric equivalent referenced in source: C 76M-82b
Application: Reinforced concrete pipes for culverts, storm drainage and sewerage.
Pipes have been classified into five basic categories, Classes I to V, with respective design standards given in five tables.
Criteria for approval, acceptance or rejection are based on tests performed on pipes to determine load-bearing capacity, material quality and water absorption, together with inspection for visual defects and imperfections.
As an alternative, the crushing test on concrete cores cut from the pipe barrel or a curved concrete cylinder may be used against the load-bearing test.
The source describes complete details for placement of steel reinforcement inside pipe walls, space required between each steel layer, concrete cover toward internal/external wall surfaces, and lap lengths for welded or overlapped bars/wires.
Permissible variation in internal diameter, wall thickness, pipe length, opposite ends and the position/area of reinforcement are also described.
Standards note: The supplied original source contains historical designations including ASTM C14-82, ASTM C76-86 and ASTM C76-82b / C76M-82b. They are retained here as source-derived information and are not presented as confirmation of the current ASTM edition. Verify the current project-required standard and approved drawings.
Reinforced Concrete Poles
Hollow octagonal tapered reinforced concrete poles.
Fabrication process and technical data below are retained from the supplied original product information.
Fabrication Process
The reinforced steel bars within the steel mould walls of the hollow, octagonal shape poles are pre-tensioned and tied in the correct position and alignment, duly ensuring a uniform concrete cover of the specified minimum all around.
Highest concrete compaction is subsequently accomplished through known methods of vibration, including internal, external and centrifugal vibration, during and after spinning of the mould filled with the desired quantity and quality of concrete.
After a suitable time interval for initial cement setting, the mould is removed and the pole is left to dry for a short while before being lifted with mechanical pulleys at predetermined spots and submerged completely into adjoining water tanks for curing and strength development.
Curved ribbed brackets for single/double lamps and fixtures are also manufactured, with the source describing their appearance as suitable for different environments.
