ORIENTED UNPLASTICIZED POLYVINYL CHLORIDE (PVC-O) PIPES FOR WATER SUPPL
summary
Oriented Unplasticized Polyvinyl Chloride (PVC-O) pipes are high-performance plastic pipes manufactured by stretching PVC-U material in a controlled process to improve molecular orientation. This enhances strength, impact resistance, and durability. PVC-O pipes are widely used in pressurized water supply systems due to their lightweight structure and superior hydraulic performance.
Why BIS Certificate is Mandatory for ORIENTED UNPLASTICIZED POLYVINYL CHLORIDE (PVC-O) PIPES FOR WATER SUPPLY
BIS certification is mandatory to ensure PVC-O pipes meet Indian Standards for pressure rating, strength, durability, and safety. Since these pipes are used for drinking water supply, certification prevents leakage, bursting, contamination, and substandard manufacturing, ensuring public health protection and regulatory compliance in India.
What is BIS Certified for ORIENTED UNPLASTICIZED POLYVINYL CHLORIDE (PVC-O) PIPES FOR WATER SUPPLY
The BIS certified specification defines requirements for raw material quality, molecular orientation process, pressure class, dimensions, wall thickness, hydrostatic strength, impact resistance, and performance testing. It ensures PVC-O pipes comply with Indian Standards for safe, durable, and efficient potable water distribution systems.
