uPVC PIPES & FITTINGS

Unplasticized Polyvinyl Chloride (uPVC) Plumbing pipes are manufactured from rigid polyvinyl chloride resin without the addition of plasticizers. These pipes are strong, durable, and resistant to corrosion, making them long-lasting and difficult to damage. Since uPVC does not rust or chemically react with water over time, it is widely used for cold water applications such as plumbing systems, potable water supply lines, underground drainage, and sewage pipelines. Joining of Flowkem® Neerflow™ pipes and fittings is a simple and reliable process using one-step solvent cement. The jointing operation can be carried out quickly and efficiently with minimal tools, such as a pipe cutter/knife, a chamfering tool, and solvent cement. This solvent welding process ensures a strong, leak-proof, and permanent joint, while also reducing installation time, labour requirements, and overall installation cost.

UPVC Plumbing Pipes are produced in Iron Pipe Size (IPS) from ½" (15mm) to 6" (150mm) in two different Schedule is Sch-40 & Sch-80, as per ASTM D1785. & UPVC Plumbing Fittings are also produced in Iron Pipe Size (IPS) in two different Schedule is Sch-40 from ½" (15mm) to 2" (50mm) as per ASTM D2466 & Sch-80 from ½" (15mm) to 4" (100mm) as per ASTM D2467. All SCH 40 and 80 pipes are made from identical compound with the same physical properties, & also All SCH 40 and 80 fittings are made from identical compound with the same physical properties, conforming to all ASTM standards.

1. What is UPVC Material ? Unplasticized polyvinyl chloride (uPVC) is a rigid thermoplastic used for pipes and fittings. It contains no plasticizers, giving it high stiffness, chemical resistance, and dimensional stability for cold-water. 2. How do I cut and prepare uPVC pipe for joining? Use a fine-toothed saw or pipe cutter, deburr the cut edge, chamfer the spigot slightly, and clean both surfaces. For solvent joints, apply primer if required, then cement, and assemble within the pot life. 3. What is uPVC Plumbing pipe? uPVC (Unplasticized Polyvinyl Chloride) pipe is a rigid thermoplastic pipe used for cold water distribution, plumbing systems, irrigation, and industrial fluid handling due to its corrosion resistance and long service life. 4. Which standards govern uPVC pressure pipes? uPVC plumbing pipes are manufactured according to ASTM D1785, which specifies dimensions, pressure ratings, and material requirements for Schedule 40, 80, and 120 pipes. 5. Which standards apply to uPVC fittings? uPVC pressure fittings are manufactured according to: ASTM D2466 – Schedule 40 fittings ASTM D2467 – Schedule 80 fittings These standards define dimensions, tolerances, pressure ratings, and performance requirements. 6. What sizes are available in ASTM D1785 pipes? Typical sizes range from: ½ inch (15 mm) to 24 inch (600 mm) depending on the manufacturer and application. 7. What joining method is used for uPVC pipes and fittings? The most common joining method is Solvent Cement Welding, which chemically fuses the pipe and fitting to create a permanent leak-proof joint. 8. What is the temperature limit for uPVC pipes? uPVC pipes are generally recommended for cold water applications up to approximately 60°C. 9. What is the difference between Schedule 40 and Schedule 80 pipes? Wall Thickness is Standard for Schedule 40 and Thicker for Schedule 80 Pressure Rating is Medium for Schedule 40 and Higher for Schedule 80 Weight is Lighter for Schedule 40 and Heavier for Schedule 80 Schedule 40 is for Domestic plumbing and Schedule 80 is for Industrial / high pressure application _Schedule 80 pipes provide greater pressure handling capacity due to thicker walls._ 10. What testing is required for ASTM uPVC pipes? Typical quality tests include: - Hydrostatic pressure test - Impact resistance test - Dimensional inspection - Burst pressure test - Material density test
