SHREE HARISAI SPUN PIPE FACTORY is equipped with most modern state-of-the-art plant and machinery manufacturing process.

Following are the stages in manufacturing process using wet cast spinning method or vertical dry cast method.

1. Forming Steel reinforcement Cages
2. Concrete Mixing and Feeding
3. Casting Pipe and Manhole
4. De-molding and Curing
5. Natural Curing
6. Coating

Spinning Method: In this method wet Concrete is placed in rotating Outer Mould and consolidation of concrete is achieved by vibration and compaction in combination with centrifugation. Photo below shows casting pipe by Spinning Method.

Vertical Dry Cast Method: In this method semi dry mix concrete is placed in the Mould and consolidation of concrete is achieved, by vibration of Inner Core, in case of pipes and by vibration of table, in case of Manholes.
