Detailed answers addressing engineering considerations, jointing, testing, and consultant submittals.
ALFA manufactured and supplied NEMA TC-2 EPC-40 and DB-120 rigid PVC electrical and communications ducting (2" to 6"), EPC-80 heavy conduits for heavy vehicle crossings, and custom long-radius sweep bends.
Logistics parks endure constant heavy dynamic wheel loading from 40-foot articulated container trucks. NEMA TC-2 conduits possess superior crush resistance and deflection stiffness compared to standard commercial conduits.
Extruded from high-modulus virgin PVC compound, ALFA conduits maintain excellent pipe stiffness that resists soil surcharge and concrete encasement pressures without cross-sectional ovalling.
The mirror-smooth extruded inner surface reduces friction resistance by over 30% compared to concrete ducts, allowing contractors to pull long, continuous medium-voltage cables without cable sheath damage.
Precision-formed integral bell sockets fused with heavy-bodied solvent cement create airtight and watertight joints, preventing groundwater infiltration and silt accumulation in the cable corridors.
The submittal package contained ALFA's Saudi Aramco Vendor Approval (#10116102), ISO 9001:2015 certificates, SASO conformity licenses, and independent crush test reports conforming to NEMA standards.
Yes. Our fabrication shop produced custom 45° and 90° sweep bends with radiuses up to 6D, ensuring gentle cable bend radiuses compliant with Saudi Electricity Company (SEC) standards.
Unlike flexible corrugated ducts, rigid PVC possesses a hard, impenetrable wall that rodents and subterranean insects cannot gnaw through, eliminating underground cable fault risks.
Yes. Formulated with high-grade PVC resin, our conduits are inherently fire-resistant and self-extinguishing, with an oxygen index exceeding 30%, preventing flame propagation in cable vaults.
ALFA NEMA conduits deliver a dielectric strength exceeding 20 kilovolts per millimeter (>20 kV/mm), providing complete electrical insulation for high-voltage transmission lines.
Shipments were dispatched on dedicated flatbed trucks from our Jeddah plant, grouped into phased bundle deliveries matching the contractor's trench excavation and duct-laying schedule.
Yes. We supply modular plastic conduit spacers that maintain uniform horizontal and vertical duct spacing for complete concrete encasement in high-density utility corridors.
Constructed from chemically inert, corrosion-free thermoplastic, the underground duct bank delivers an operating design service lifespan exceeding 50 to 100 years.
