Q4. Which class PVC pipe is best?

The best class of PVC depends on the application and the required pressure rating. At Utkarsh Pipes and Fittings, one of the best PVC pipe company in India, our PVC pipes are colour-coded for ease of identification. For household plumbing, Class 2 and Class 3 are common, while high-pressure applications often require Class 5.

Q5. How to calculate PVC pipe size?

Figuring out the right PVC pipe size starts with knowing how much water flow is required for your application, the pressure it will be under, and how far it has to travel. Generally, the PVC pipe size is based on the internal, external diameters and the thickness of the wall. We help our customers choose the ideal pipe size with the help of sizing charts and pressure flow calculations to get the best performance and efficiency.

Q6. What are the quality standards for PVC pipes?

Utkarsh Pipes and Fittings comply with ASTM and ISO guidelines, ensuring consistency, durability, and safety for plumbing and industrial applications.

The two main grades produced by Utkarsh Pipes and Fittings are uFLOuPVC (Unplasticized PVC and cPVC (Chlorinated PVC). At Utkarsh Pipes and Fittings, both grades are produced under strict ISI and ISO standards to ensure high performance and longevity.

While uPVC is most commonly used for PVC pipes for plumbing, irrigation, and industrial use. cPVC is preferred for applications for both hot and cold water supply. Each grade has its specific features depending on the area of application.
