PVC-O Pipes

OPTIFLUX™ PVC-O Pipes – High Strength, High Performance

OPTIFLUX™ High-Strength Oriented PVC Pipes (PVC-O) are manufactured using state-of-the-art technology to deliver exceptional performance in water conveyance applications. These pipes are produced in strict compliance with Indian Standard IS 16647:2017, which specifies the requirements for Oriented Unplasticized Polyvinyl Chloride (PVC-O) pipes for water supply. Additionally, they conform to ISO 16422:2014, the globally recognized standard for pipes and joints made of PVC-O for the conveyance of water under pressure.

PVC-O is created through a process of molecular orientation, where the amorphous structure of conventional PVC is transformed into a layered, ordered structure. This advanced manufacturing technique significantly enhances the mechanical properties of the material, resulting in:

  • Superior Strength and Toughness – PVC-O pipes offer remarkable resistance to internal pressure, external loads, and impact, making them highly durable in demanding conditions.

  • High Hydraulic Capacity – With a smoother inner surface and reduced friction losses, PVC-O pipes ensure higher flow rates compared to conventional pipes of the same diameter.

  • Lightweight and Easy Handling – Despite their high strength, these pipes are lighter in weight, facilitating easier transport, handling, and installation.

  • Corrosion and Chemical Resistance – Unlike metallic alternatives, PVC-O pipes are immune to rust, scaling, and most chemical reactions, ensuring a longer service life.

  • Sustainability and Cost Efficiency – The longer life cycle, reduced maintenance, and energy-efficient production process make PVC-O pipes an environmentally friendly and economically viable choice.

Engineered for reliability, OPTIFLUX™ PVC-O pipes are widely used for potable water supply, irrigation networks, industrial water conveyance, and pressure piping systems. By meeting both national and international standards, OPTIFLUX™ ensures that its products consistently deliver safety, efficiency, and long-term performance in water infrastructure projects.

Guidelines for storage and Installation of OPTIFLUX PVC-O Pipes

       Storage  
  • Store the pipes horizontally on a flat surface and place supports on every 1.5 meter to avoid the bending of the product.
  • Avoid scratches especially on the crest of socket.
  • Do not stack pipes more than 1.5 meter height 
  • The socket of the pipes should be free, alternative sockets and end during stacking.
  • If the pipes are stored in direct sunlight, cover the pipes with opaque material.
Installation

OPTIFLUX PVC-O Pipes are recommended for underground use only.

For Installation the trench shall be free of stones at the bottom and at the sides. The minimum width of the trench based on nominal diameter of the pipes. As a rule of thumb, when there is no road traffic involved, the pipes crown will be at a minimum depth of 0.6 meter, with road traffic the minimum depth is 1 meter.
