UPVC High Pressure Pipes - ASTM Threaded Pipes

What Are uPVC High Pressure ASTM Threaded Pipes Used For?

Not all uPVC pipes are the same. Supreme's uPVC High Pressure ASTM Threaded Pipes are a distinct category, manufactured as per ASTM D-1785 with threaded ends, as opposed to the solvent weld joints used in AquaGold and other plumbing systems. The threaded design makes them directly compatible with standard GI fittings, giving them a specific advantage in applications where threaded connections are the installation standard. These high pressure pipes cover plumbing, water supply lines, and borewell jet pump lowering, three distinct use cases that require the pressure integrity and joint reliability that the ASTM D-1785 standard guarantees. Available from ½" to 8" in SCH 40, SCH 80, and SCH 120, Supreme's upvc pipes and fittings in this range offer a proven, cost-effective alternative to GI across all three schedules.

What is the Difference Between SCH 40, SCH 80, and SCH 120 uPVC Pipes?

Schedule refers to wall thickness at a given nominal diameter. A higher schedule number means a thicker wall, higher pressure rating, and greater mechanical strength. SCH 40 is the standard choice for general plumbing and water supply applications where pressure requirements are moderate. SCH 80 has a thicker wall than SCH 40 at the same nominal diameter, making it the right specification for higher pressure lines, threaded connections under stress, and applications where the pipe is subject to mechanical load. SCH 120 is the heaviest of the three, specified for the most demanding pressure pipes applications where maximum wall thickness and pressure rating are required. Supreme uPVC ASTM Threaded Pipes are available in all three schedules from ½" to 8", conforming to ASTM D-1785, giving engineers and contractors the flexibility to specify the correct schedule for each section of the installation.

Can uPVC Threaded Pipes Be Used with GI Fittings?

Yes. Supreme uPVC ASTM Threaded Pipes have threaded ends that are compatible with standard GI fittings, making them a direct replacement for GI pipes in existing or new threaded plumbing installations. This compatibility is a key practical advantage. It means the pipes can be installed using the same fittings and techniques already familiar to plumbers working with GI systems, with no need for specialist tools or training. For borewell applications, the uPVC pipe for borewell jet pump lowering application specifically benefits from this threaded design. The pipes can be lowered section by section using standard threaded couplings, carrying the weight of the pump and water column safely within the rated load. One important note: these pipes are not recommended for use with AquaGold fittings. The two systems use different jointing methods and must not be mixed.

Why Are uPVC Pipes Better Than GI Pipes for Plumbing?

Supreme uPVC ASTM Threaded Pipes are 40 to 50% more economical than GI pipes and the cost advantage does not come at the expense of performance. GI pipes corrode from within over time, building up scale that reduces flow rate and eventually compromises water quality. uPVC is completely immune to chemical, electrolytic, and galvanic corrosion. The internal surface stays smooth throughout its service life, maintaining consistent flow without the scaling or rust contamination associated with metal systems. Being non-metallic, these water pressure pipes are safe for potable water supply with no risk of metal leaching. They are also self-extinguishing, eliminating the need for fire-resistant coatings required on GI and other metal pipe systems. Maintenance requirements are minimal with no painting, no coating, and no periodic treatment of any kind as per upvc pipe manufacturers in india standards.

What Sizes and Applications Are Available in Supreme ASTM uPVC Pipes?

Supreme uPVC ASTM Threaded Pipes are available from ½" to 8" across SCH 40, SCH 80, and SCH 120 pressure classes, conforming to ASTM D-1785. The application base is broader than most buyers realise. Beyond standard residential and commercial plumbing and water supply, these uPVC high pressure plumbing pipes are used for borewell jet pump lowering, industrial process lines, swimming pool pipework, and firefighting mains. The range covers both plain and threaded end options, giving contractors the flexibility to choose the right connection method for each installation requirement. Where the project calls for a complete threaded system, Supreme's range ensures every size needed across all three schedules is available from a single source.
