uPVC Pressure Piping System
An exhaustive range of uPVC pressure pipes and fittings is offered, manufactured as per IS:4985-2021 standards, and available in 20 to 450mm sizes across different pressure classes. Both solvent cement and elastomeric rubber seal joint types are provided. The system includes moulded fittings (IS:7834) and fabricated fittings (IS:10124) for a complete solution. These pipes are ideal for irrigation, water supply, industrial process lines, swimming pools, and firefighting mains. Compared to CI, DI, or RCC pipes, they are lighter, easier to install, corrosion and chemical resistant, offer higher flow rates, longer life, and are more economical. Approved by MJP.
