uPVC Watermain Pressure Pipes in Saudi Arabia (PN6, PN10, PN12.5, PN16)
4B Factory manufactures uPVC watermain pressure pipes at our Al-Kharj plant for water utility, infrastructure, irrigation, and industrial buyers across Saudi Arabia. The product line covers pressure classes PN6 (SDR 41), PN10 (SDR 26), PN12.5 (SDR 21), and PN16 (SDR 17), in diameters from 63mm through 500mm, designed for buried water distribution, transmission mains, network laterals, and pressurised irrigation supply. Each pipe is extruded from drinking water grade unplasticized polyvinyl chloride and tested to SASO ISO 1452 and DIN 8061 / 8062 references for hydrostatic strength, surge resistance, and dimensional accuracy.
Standard length is 6 metres. Joints are integral socket with EPDM rubber ring (push fit), or plain end for solvent weld.

Sizes, SDR, and Working Pressure
The table below summarises the nominal pressure for each SDR class on the standard PVC-U compound at 20°C. For service above 20°C, apply the SASO ISO 1452 derating factors. Long term water hammer and surge events must also be considered when selecting the class.

|---|---|---|---|
| PN6 | 41 | 6 | Low pressure rural and irrigation networks |
| PN10 | 26 | 10 | Distribution mains, residential supply |

Standards and Compliance
- SASO ISO 1452, the Saudi reference for plastic piping systems for water supply and for buried and above ground drainage and sewerage under pressure.
- DIN 8061 / 8062, the German reference set for PVC-U pressure pipes used widely in Saudi water utility specifications.
- EN 1452, the European reference for PVC-U piping systems for water supply.
- NSF 61 grade compound on request, for projects that need explicit drinking water contact certification.
- Documentation included with each shipment: hydrostatic test record, dimensional inspection report, raw material certificate, and batch traceability sheet.
Applications
- Potable water distribution networks for cities, districts, and master plan developments.
- Trunk transmission mains carrying water from reservoirs to district networks.
- Network laterals and service connections to villas, towers, and commercial buildings.
- Pumped irrigation mains for landscaping, farms, golf courses, and date plantations.
- Industrial process water lines, within chemical compatibility limits.
- Fire fighting water mains, where the project specification accepts uPVC for the duty.
- Pressurised supply lines on labour camps and temporary site facilities.
Why Choose 4B Factory for Watermain Pressure Pipe

- Drinking water grade compound. Manufactured for potable water service in line with SASO ISO 1452.
- Push fit EPDM joint. Faster trench work, fewer leak points, less labour.
- Bulk capacity. Project loads from a few hundred metres to multi kilometre framework deliveries.
- Technical support. Our engineering team helps with class selection, surge protection, and connection to existing networks.
Delivery Across Saudi Arabia
Watermain pipe is dispatched from Al-Kharj on covered trailers to project sites in Riyadh, Jeddah, Dammam, Khobar, Makkah, Madinah, Tabuk, Qassim, the Eastern Province, the Western Region, the Northern Borders, and across NEOM, Red Sea, Diriyah, and Vision 2030 giga project zones. Phased call off, project specific marking, and large diameter coordination are all supported.
Frequently Asked Questions
Yes. The compound is unplasticized PVC, manufactured for potable water service to SASO ISO 1452. We can supply an NSF 61 grade variant when the project specification calls for that explicit drinking water contact certification.
Pressure class is driven by static head plus surge pressure. A simple guide: PN6 is for low pressure rural and irrigation networks, PN10 is the most common choice for residential and district distribution, PN12.5 handles areas with higher static head, and PN16 is selected for trunk mains, pumped systems, and surge prone networks. Send us the design pressure and we will confirm the class.
SDR is the ratio of outside diameter to wall thickness. The smaller the SDR, the thicker the wall and the higher the pressure rating. PN is the nominal pressure in bar at 20°C. The two are linked: for example, PN10 in PVC-U is SDR 26 under SASO ISO 1452.
The standard joint is an integral socket with an EPDM rubber ring, designed for push fit assembly. This is the fastest, most leak resistant joint for buried watermains. Solvent weld plain end pipe is also produced on request.
Yes, when correctly bedded and laid below frost line (not an issue in most of Saudi Arabia) and with cover sufficient to handle the surface load. Underground PVC-U is not exposed to UV and is highly resistant to most soil chemistries.
Yes. Hydrostatic pressure test results, dimensional inspection reports, raw material certificates, and batch traceability are issued with every dispatch. These are formatted for NWC, MEWA, MODON, Aramco, and municipality submittal.
Yes. We support framework call off pricing, project specific marking, dedicated production slots, and large diameter coordination for major water and infrastructure programmes including NEOM, Red Sea, Diriyah, and Qiddiya support packages.
A correctly designed and installed uPVC watermain is engineered for a service life of 50 years and more, with strong resistance to internal corrosion, scaling, and the biological attack that limits the life of metallic mains.
