Detailed answers addressing engineering considerations, jointing, testing, and consultant submittals.
ALFA manufactured and delivered ASTM D1785 Schedule 80 uPVC pressure piping for auxiliary chilled water and booster risers, DIN 19531 DWV systems for sanitary drainage, and NEMA TC-2 conduits for electrical plant rooms.
Schedule 80 heavy-wall construction delivers high tensile strength and pressure containment (up to 850 psi for small sizes), effectively absorbing hydraulic pressure spikes and operational pump shut-off pressures.
ALFA supplied factory-fabricated long-radius sweep bends (R = 3D to 5D) instead of standard short-radius elbows, significantly smoothing hydraulic direction changes and mitigating pressure surge shockwaves.
The dense, heavy-wall formulation of DIN 19531 uPVC dampens airborne and structure-borne wastewater turbulence noise, meeting stringent consultant noise criteria for commercial and hospitality projects.
Assembled vertical risers were hydrostatically tested at 1.5 times working pressure for 4 hours on site, following factory hydrostatic burst testing at 3.8x nominal pressure with zero joint weepage or pressure loss.
Operating from our central Jeddah plant with regional logistics hubs, ALFA scheduled night-time and early-morning flatbed deliveries with offloading crane permits directly to urban jobsite gates.
Yes. Complete Material Approval Request (MAR) dossiers containing ISO certificates, SASO licenses, Aramco Vendor Registration #10116102, and CAD submittal cut sheets were approved on first submission.
Heavy-duty industrial solvent cement (ASTM D2564) and purple primer (ASTM F656) were applied using calibrated insertion techniques to achieve full-depth, monolithic joint fusion.
Yes. ALFA manufactures transition adapters, stub flanges (ANSI Class 150), and threaded fittings that enable seamless transitions to metallic valves, pumps, and water meters.
ALFA's technical desk provided expansion loop sizing and guide clamp spacing schedules, ensuring thermal growth during seasonal HVAC operation is absorbed without pipe buckling.
Every truckload was accompanied by a project-referenced Mill Test Certificate (EN 10204 Type 3.1) detailing lot hydrostatic pressure tests, wall thickness metrology, and inspector sign-off.
Yes. Our fitting fabrication department fabricates equal tees, reducing headers, and flanged manifold assemblies to contractor shop drawings, minimizing on-site cutting and solvent welding.
Our pipes are stabilized with non-toxic calcium-zinc organic systems containing zero lead or heavy metals, ensuring 100% compliance with WHO and Saudi health standards for drinking water.
