Our Rigid PVC Electrical & Telecom Conduits 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 NEMA TC-2, ASTM F512, SASO IEC 61386, NEMA TC-3.
Available in sizes from 1/2" to 6" IPS, supporting EPC-40 (Direct Burial) & EPC-80 (Heavy Slab / High Impact).
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.

Rigid PVC is an outstanding electrical insulator with dielectric strength exceeding 20 kV/mm and high insulation resistance (> 10¹² Ω·cm), preventing short circuits and fault current propagation between adjacent duct ways.
EPC-80 features up to 50% greater wall thickness than EPC-40, providing exceptional impact strength and crush resistance required where conduits are exposed to heavy dynamic traffic wheel loads or bridge vibration.
The mirror-smooth extruded inner surface delivers a dynamic coefficient of friction (μ < 0.22), reducing cable pulling tension by up to 30%, which prevents cable jacket stretching and reduces the required number of pulling manholes.
Yes. Conduits comply with Saudi Aramco SAES-T-911 and SEC outside plant telecommunication specifications for underground multi-way duct banks supporting fiber optic and copper communication cables.
Our Jeddah fabrication plant thermoforms custom sweep bends in 45° and 90° configurations with radiuses ranging from 3D up to 6D (or 1,000mm to 1,500mm radius), complying with minimum cable manufacturer bending limits.
Rigid PVC provides a dense, impenetrable polymer wall with a Shore D hardness exceeding 80, preventing termite gnawing, rodent damage, and subterranean root penetration in municipal rights-of-way.
