ALFA Al-Arabia manufactures high-density unplasticized polyvinyl chloride (uPVC) pressure pipes conforming strictly to DIN 8062, ISO 1452, SASO 14/1517, and ASTM D1785. Engineered with 100% lead-free virgin resin, our pressure series delivers exceptional hydraulic efficiency (Hazen-Williams C=150), extreme chemical resistance to saline groundwater, and guaranteed burst resistance >3.5x working pressure.

Our uPVC Pressure Piping Systems are manufactured using 100% virgin lead-free resin under strict ISO 9001 and Saudi Aramco Vendor #10116102 quality standards, delivering superior burst strength, thermal stability, and corrosion immunity.
Depending on the exact specification, systems comply with DIN 8062, ISO 1452, SASO 14/1517, ASTM D1785, ASTM D2241.
Available in sizes from 20 mm to 500 mm (1/2" to 12" IPS), supporting PN 6, PN 10, PN 16, PN 25 / Schedule 40 & Schedule 80.
Thermoplastic piping provides 100% galvanic corrosion immunity, making it impervious to high sulfate and chloride sabkha soils found in coastal Saudi regions.
Every order is accompanied by factory mill test certificates (MTC), dimensional compliance sheets, and third-party laboratory burst test reports.
Yes, our Jeddah fabrication plant manufactures matching sweep bends, tees, and flange adaptors fully rated for system working pressures.
Western Province: 24h; Central/Riyadh: 24-48h; Eastern/Northern/Southern: 48-72h.

Water hammer wave velocity in uPVC (c ≈ 300–400 m/s) is roughly one-third that of ductile iron or steel (c ≈ 1,000–1,200 m/s), resulting in substantially lower peak surge pressure spikes for sudden pump stop events.
Class I crushed angular stone (6mm to 20mm) or Class II clean, well-graded coarse sand compacted to 90% Standard Proctor density provides optimal continuous lateral support without pipe indentation.
Yes. ALFA manufactures flanged adaptors with ductile iron backup rings conforming to EN 1092-2 PN 10/16 and ASME B16.5 Class 150, enabling seamless, leak-proof mechanical transitions to isolation and check valves.
Saudi NWC and international standards mandate hydrostatic site testing at 1.5 times the maximum designed operating pressure, maintained for a minimum of 2 to 4 hours with allowable pressure loss less than 0.2 bar.
Buried pipes are continuously restrained by soil friction and compaction, eliminating snaking. Above-ground installations require guided pipe clamps and expansion loops calculated using an expansion rate of 0.07 mm/m/°C.
Every single pipe length is continuously inkjet-marked with resin lot numbers, standard, size, pressure rating, Aramco Vendor Code #10116102, and date of manufacture, cross-referenced on the authenticated Mill Test Certificate.
