Frequently Asked Questions (FAQs)

Q1: What are the primary differences between UPVC and PVC pipes?

A: The main difference is that UPVC (Unplasticized PVC) does not contain plasticizers, making it more rigid and suitable for construction and piping applications, while PVC (Polyvinyl Chloride) is more flexible and commonly used in applications requiring flexibility.

Q2: Can UPVC pipes be used for hot water systems?

A: UPVC pipes have a lower temperature tolerance and are generally not recommended for hot water systems. CPVC (Chlorinated PVC) is a better alternative for hot water applications due to its higher temperature resistance.

Q3: How do you join UPVC pipes and fittings?

A: UPVC pipes and fittings can be joined using solvent cement welding, where a special adhesive is applied to the surfaces to create a strong, permanent bond.

Q4: Are UPVC pipes safe for drinking water?

A: Yes, UPVC pipes are non-toxic and safe for drinking water applications, complying with health and safety standards.

Q5: How do you protect UPVC pipes from UV degradation?

A: UPVC pipes used outdoors should be protected from UV light by applying a UV-resistant coating or using protective sleeves to prevent degradation.

Q6: What are the pressure ratings for UPVC pipes?

A: The pressure ratings for UPVC pipes vary depending on the diameter and wall thickness. It is important to select pipes that meet the specific pressure requirements of your application.

Q7: Can UPVC pipes be recycled?

A: Yes, UPVC pipes are recyclable. Proper recycling practices should be followed to minimize environmental impact.

Q8: How does UPVC compare to metal pipes in terms of maintenance?

A: UPVC pipes require less maintenance than metal pipes as they are resistant to corrosion, chemical damage, and biological growth, resulting in lower long-term maintenance costs.
