Conveyance of brackish deep-aquifer groundwater with high dissolved mineral salinity (TDS > 3,500 ppm) across expansive agricultural plots exposed to extreme desert surface temperatures (+48°C) without chemical scaling, corrosion, or UV embrittlement.
ALFA supplied DIN 8062 metric pressure pipes (DN 63mm to DN 250mm) featuring 100% corrosion-proof virgin uPVC with smooth hydraulic bore (Hazen-Williams C=150) that prevents mineral deposition, coupled with precision-perforated subsurface drainage lines for soil salinity management.

ALFA manufactured and delivered DIN 8062 metric uPVC pressure pipes (DN 63mm to DN 250mm, PN 10 and PN 16) for main irrigation trunk lines, and DIN 1187 perforated subsurface drainage pipes for soil salinity leaching.
Al-Qassim deep well water often carries elevated total dissolved solids (TDS) and sulfate concentrations. Unlike ductile iron or galvanized steel which corrode rapidly, uPVC is completely inert, eliminating scale accumulation and wall pitting.
ALFA's UV-stabilized compound formulation contains rutile titanium dioxide and high-efficiency heat stabilizers that prevent photo-oxidative degradation and polymer chain embrittlement during surface staging.
Large diameter lines (DN 110–250mm) utilized automated Rieber elastomeric rubber ring sockets. This push-fit assembly allowed rapid installation across sandy desert trenches while accommodating thermal expansion and contraction.
With a Hazen-Williams roughness coefficient of C = 150, ALFA uPVC pipes maintain lower friction head loss compared to metallic pipes (C = 100–120), reducing required pump horsepower and ongoing electrical energy consumption.
Engineered slotting patterns allow excess saline irrigation water to enter the sub-drainage network, lowering the perched water table and preventing toxic root-zone salt crusting in intensive date cultivation.
Yes. The installed irrigation network underwent hydrostatic pressure testing at 1.5 times working pressure (15 bar for PN 10 lines) held for 4 hours with zero measurable pressure loss.
ALFA supplied factory-fabricated equal and reducing tees, flanged stub ends for air-release valve stands, and long-radius sweep bends to minimize dynamic pumping surge.
Yes. Our 100% lead-free, non-toxic calcium-zinc stabilized formulation releases zero harmful chemical leachates, making it fully compliant with international agricultural standards.
Articulated flatbed trucks with dedicated pipe bunking were dispatched from our Jeddah plant directly to farm storage laydowns within 24 to 48 hours of call-off.
Yes. Our computerized perforation tooling creates clean, burr-free slots with widths from 1.0mm to 3.0mm in 120°, 220°, or 360° patterns to match project geotextile filter wrap criteria.
When installed according to recommended bedding standards, ALFA uPVC piping networks deliver an operational service lifespan exceeding 50 to 100 years without maintenance.
Yes. Our hydraulic engineering desk assists farm managers and contractors with friction head loss calculations, manifold pipe sizing, and surge analysis.
