PVC Pipes for Water Supply
4B Factory manufactures uPVC water-supply pipe for potable distribution, municipal mains and building services across Saudi Arabia. Our Loc-Ring watermain pressure pipe runs 50–315 mm in Class 4 (10 Bar) and Class 5 (16 Bar), with ASTM Schedule 40/80 pressure pipe for pumped and plant lines — factory-direct from Al-Kharj with SAS/SASO documentation for NWC and municipal approval.
Rated
Pipe Built for Saudi Water Networks
Water-supply pipe in Saudi Arabia has to cope with aggressive soils, saline coastal groundwater and low-hardness desalinated water — conditions that corrode metallic pipe from the outside in and the inside out. uPVC is fully non-metallic, so it is immune to the electro-chemical and galvanic corrosion that shortens the life of ductile iron and steel mains.
For potable distribution and municipal mains, our uPVC watermain uses a Loc-Ring integral socket with a dual compression seal that holds against both positive surge and negative (vacuum) pressure. For pumped lines, plant pipework and smaller-diameter pressure runs, ASTM Schedule 40/80 PVC pipe provides a solvent-welded, leak-free alternative.

Frequently Asked Questions
Yes. 4B Factory uPVC watermain pressure pipe is manufactured from non-toxic uPVC compound for potable water distribution, and is non-metallic so it does not corrode or leach metal into low-hardness desalinated water common across Saudi networks.
Class 4 uPVC pipe is rated to 10 Bar and Class 5 to 16 Bar. Distribution mains commonly use Class 4, while higher-head or pumped lines use Class 5. Our team can match the class to your network's operating and surge pressure.
Yes. Pipes are manufactured to Saudi Standards (SAS/SASO) and supplied with compliance documentation, supporting submission for National Water Company (NWC), Ministry and municipal water-supply tenders.
Use uPVC Loc-Ring watermain (50–315 mm) for buried distribution and municipal mains. Use ASTM Schedule 40/80 solvent-weld pipe for pumped lines, booster stations and plant pipework where a rigid welded joint is preferred.
uPVC water pipe offers a design life of 50 years or more in buried service. Its corrosion immunity and resistance to aggressive soils and saline groundwater make it far more durable than metallic mains in Saudi ground conditions.
