Applications of Duke uPVC Pressure Pipe — Agriculture & Industry
- Agriculture & Irrigation: Duke’s uPVC pressure pipe is the most trusted solution for farm irrigation — connecting water pumps to distribution networks. Available in Class-1 to Class-6, these pipes handle low-pressure drip systems to high pressure water pipe requirements for sprinkler irrigation.
- Car Wash & Industrial Water Lines: For pressure pipe for car wash, commercial cleaning, and industrial water distribution, Duke’s Class-4 to Class-6 pressure pipes (0.80 MPa to 1.25 MPa) deliver consistent high-pressure performance with zero leakage — thanks to elastomeric sealing rings.
- Rural & Urban Water Supply: From village water distribution to urban high-rise buildings, Duke’s water pressure pipe system supports long-distance transmission. The smooth internal surface minimizes friction loss, reducing pumping costs significantly. Compatible with air release valve and pipe clips for complete installation.

FAQs
What is the IS code for uPVC pressure pipe?
IS 4985:2021 — the latest Bureau of Indian Standards specification for unplasticized PVC pressure pipes for water supply. Duke Pipes manufactures strictly as per IS 4985:2021, updated from the older IS 4985:2000.
What is uPVC pressure pipe used for?
Used for agriculture & irrigation, rural & urban water supply, industrial water distribution, cable ducting, car wash systems, swimming pools, and firefighting mains. Available in 6 pressure classes — Class-1 to Class-6.
What are the pressure classes in IS 4985 uPVC pressure pipe?
6 pressure classes: Class-1 (0.25 MPa), Class-2 (0.40 MPa), Class-3 (0.60 MPa), Class-4 (0.80 MPa), Class-5 (1.00 MPa), Class-6 (1.25 MPa). Choose based on your system pressure requirement.
Does uPVC pressure pipe need an air release valve?
Yes — for long-distance networks, an air release valve (ARV) prevents air locks and water hammer. Duke’s uPVC pressure pipes are compatible with standard air release valves and uPVC butterfly valves.
How is uPVC pressure pipe tested?
All Duke uPVC pressure pipes undergo hydrostatic pressure testing as per IS 4985:2021 before dispatch — tested for leaks, wall thickness, and working pressure rating. Duke’s National Quality Award (2007) reflects our commitment to quality testing.
