1. Are Flowkem CPVC Flow systems suitable for potable water? Yes, CPVC material used is non-toxic and safe for potable water applications, complying with drinking water standards. 2. What is the difference between SDR 11 and SDR 13.5 CPVC pipes? Standard Dimension Ratio (SDR ). SDR-11 Pipes have more wall thickness and higher pressure ratings than SDR-13.5 for the given size. 3. What precautions should be taken for CPVC plumbing pipes while using it for gas geysers and electric water heaters, and solar water heaters? When connecting CPVC pipe to water heaters, maintain at least 18 inches of metallic piping between the heater and the CPVC plumbing system to prevent heat damage. Always use appropriate CPVC fittings designed for hot water applications. For solar heaters, ensure that temperature regulators keep water below 180°F (82°C), as CPVC pipes are rated for continuous operation up to 180°F. Install expansion loops or offsets to accommodate thermal expansion in hot water lines, ensuring the longevity of your plumbing installation. 4. What precautions are required during installation? - Proper surface cleaning before solvent cementing - Correct curing time before pressurization - Avoid mechanical stress and misalignment - Use recommended tools and adhesives 5. What material is used in Flowkem CPVC Flow pipes and fittings? Flowkem CPVC Flow products are manufactured using Chlorinated Polyvinyl Chloride (CPVC) compound, engineered for high-temperature and high-pressure fluid handling applications. The material complies with relevant standards such as ASTM D1784 / IS 15778, ensuring consistent mechanical and thermal performance. 6. Why should customers choose CPVC over conventional piping material CPVC provides better resistance to heat and corrosion, is lightweight, easy to install, and helps reduce maintenance needs over time. 7. Is Flowkem CPVC a cost-effective solution? Yes. With durable performance, reduced maintenance, and easy installation, Flowkem CPVC provides excellent long-term value.
