High-integrity metric uPVC pressure piping systems (PN 6 to PN 25, 20mm to 500mm) engineered for municipal drinking water mains, booster pump headers, and commercial building supply across Saudi Arabia.
Direct pricing from the Jeddah plant, with technical submittal support.
Unlike metallic water mains that experience progressive tuberculation and internal scaling, ALFA's DIN 8062 uPVC pipes maintain an uncompromised roughness coefficient of C=150 over their entire 50+ year design life. This ensures maximum water velocity without energy-sapping pump head losses.
Formulated strictly with calcium-zinc and organotin stabilizers in full compliance with SASO 14/15 and international toxicological drinking water standards. Extruded with zero chemical leaching, providing pristine water purity for residential towers, hospitals, and educational institutions.
DIN 8062 specifies high hydrostatic burst safety factors, lead-free calcium-zinc stabilization conforming to SASO 14/15, and smooth interior hydraulic surfaces (C=150) that prevent calcification and bacterial biofilm attachment.
For municipal mains and pumping headers, PN 16 (16 bar) or PN 20 (20 bar) is standard. For gravity networks and branch distribution, PN 10 (10 bar) is commonly engineered.
Operating pressures are derated according to DIN 8061 thermal derating tables (factor ~0.70 at 45°C). ALFA uses virgin resin with high Vicat softening temperatures (>=79°C) to prevent thermal wall yielding.
Certified drinking-water grade EPDM elastomeric gaskets complying with BS EN 681-1 are pre-installed to ensure zero water contamination and watertight sealing up to 25 bar.
Yes, ALFA DIN 8062 pressure pipes are manufactured using 100% heavy-metal-free, organotin or calcium-zinc stabilizer formulations certified for human consumption.
ALFA uPVC achieves a roughness coefficient of C=150 compared to C=100-120 for aged ductile iron, reducing friction head loss by over 30% and significantly lowering pump energy consumption.
Yes, factory-formed long-radius sweep bends (11.25° to 90°) are manufactured at our Jeddah plant to eliminate water hammer shockwaves and minimize localized turbulence.
Under ASTM D2321, a 100-150mm bed of Class I or Class II granular aggregate (clean sand or crushed stone 5-10mm) is required beneath the pipe invert.
Lines are filled with chlorinated water (50 mg/L free chlorine) for 24 hours, then flushed with clean potable water until residual chlorine is within municipal drinking water limits.
Each shipment includes factory Mill Test Certificates (MTC) certifying batch hydrostatic pressure tests, Vicat softening point, and compliance with ISO 9001 and SASO standards.
Standard truckload dispatches from 3rd Industrial City, Jeddah reach Central and Qassim project laydown yards within 24 to 48 hours.
