Supreme Agriculture PVC Pipes (IS: 4985-2000)

Manufactured in accordance with Bureau of Indian Standards specifications (IS 4985:2000), these unplasticized polyvinyl chloride (uPVC) pressure pipes are engineered specifically for agricultural distribution networks and potable water conveyance. Designed for optimum fluid dynamics, they resist chemical, physical, and environmental degradation under demanding field conditions.
PLUMBING PIPE CLASSIFICATIONS
Under standard piping classifications such as IS 4985 for uPVC pressure pipes, numerical classes indicate the continuous working pressure rating the pipe can withstand at 27^\circ\text{C}. As the class number increases, the pipe's wall thickness and overall pressure resistance increase accordingly.
* Class 1 (Working Pressure: 0.25\text{ MPa} / 2.5\text{ kg/cm}^2 / \approx 35\text{ psi})
This class has the lowest pressure rating and features the thinnest pipe walls. It is designed primarily for non-pressure drainage, gravity-fed irrigation lines, light waste discharge, and temporary or low-stress water paths.
* Class 2 (Working Pressure: 0.40\text{ MPa} / 4.0\text{ kg/cm}^2 / \approx 57\text{ psi})
This class offers a low-pressure rating suitable for basic agricultural water distribution networks, canal water diversion, and light crop irrigation systems.
* Class 3 (Working Pressure: 0.60\text{ MPa} / 6.0\text{ kg/cm}^2 / \approx 85\text{ psi})
Featuring a medium-pressure rating, this class serves as a standard choice for main agricultural headers, primary water distribution lines, and standard residential cold-water supply plumbing.
* Class 5 (Working Pressure: 1.00\text{ MPa} / 10.0\text{ kg/cm}^2 / \approx 142\text{ psi})
This class represents a high-pressure rating built with the thickest pipe walls. It is intended for demanding applications such as multi-story building water distribution, high-pressure pump discharge mains, overhead tank supply lines, and industrial fluid transport systems.
Higher class numbers directly correspond to greater wall thickness, increased durability, and higher pressure tolerances. Selecting the correct class depends on the specific hydrostatic pressure requirements of your piping installation.

• Manufacturer Warranty: Covered by a standard 1-Year Limited Warranty against manufacturing defects, materials failure, or cracking under normal recommended operating pressures. Warranty excludes damage resulting from improper installation, over-pressurization beyond design class, or physical abuse during transport.
• Return Policy: Unused, full-length pipes in original condition may be returned within 1 days of delivery, subject to manufacturer inspection and restocking terms. Custom-cut lengths or pipes showing solvent weld marks are non-returnable.

Q1: What sizes and pressure ratings are covered under IS 4985:2000?
A: Nominal outer diameters range from 20\text{ mm} to 400\text{ mm} across standard pressure classes, including 2.5\text{ kg/cm}^2 (Class 1), 4.0\text{ kg/cm}^2 (Class 2), 6.0\text{ kg/cm}^2 (Class 3), and 10.0\text{ kg/cm}^2 (Class 5).
Q2: Are IS 4985:2000 pipes safe for drinking water delivery?
A: Yes, these pipes are non-toxic, odorless, and approved for potable water transportation, making them safe for domestic and livestock use alongside crop irrigation.
Q3: Can these pipes be buried underground?
A: Yes, they are designed for direct burial in trench installations, featuring high ring stiffness to resist soil compaction loads.
