Real-world procurement, compliance, testing, and delivery clarifications for project contractors.
Yes. ALFA uPVC pressure and sewer pipes strictly comply with NWC standard specifications, SASO 14/1517 licenses, and have been deployed in numerous municipal water contracts.
SN 8 (≥ 8 kN/m²) provides high pipe stiffness required to prevent excessive vertical deflection in deep municipal trenches (> 3m) subject to continuous urban traffic surcharge.
Our pressure pipes are formulated with zero lead or toxic stabilizers, certified under WHO drinking water criteria and tested by independent SASO-accredited laboratories.
The steel-reinforced EPDM rubber gasket is integrally thermoformed into the socket during manufacturing, preventing gasket displacement during trench jointing.
NWC specifications mandate field hydrostatic testing at 1.5 times the maximum designed operating pressure held for 2 to 4 hours with allowable pressure drop < 0.2 bar.
Yes. We manufacture custom flanged spools, segmented tees, and air valve risers conforming to NWC engineering drawings with factory pressure testing.
With a Manning's roughness coefficient of n = 0.009, ALFA pipes achieve self-cleansing velocity (≥ 0.75 m/s) at shallower gradients than concrete or clay pipes.
Direct flatbed dispatches from our Jeddah factory arrive in Jeddah within 24 hours and Riyadh within 24–48 hours, phased to match contractor trench excavation.
ALFA provides complete submittal packages: SASO licenses, ISO certificates, factory test records, Aramco vendor credentials, and sample pipe cross-sections.
