ApplicationsCategory Overview
uPVC Duct Pipes
Our uPVC duct pipes are engineered for demanding underground applications, providing robust mechanical protection for electrical cables, fiber-optic lines, and telecom infrastructure. Manufactured to BS 4660 and ISO 4435 standards, they deliver exceptional crush resistance, chemical inertness, and dimensional accuracy across a full diameter range from 50mm to 400mm.

Features & Benefits
Engineered for Demanding Infrastructure
Technical advantages built into every product in this range.
High Crush Resistance
SN4 and SN8 stiffness classes available — engineered to withstand heavy traffic loads and soil compaction pressures at burial depths up to 6m.
Electrical Non-Conductivity
Inherently non-conductive PVC material eliminates electrolytic corrosion and provides safe cable segregation in high-voltage environments.
Smooth Internal Bore
Precision-extruded smooth internal surface minimises cable-pulling friction, enabling longer cable runs with reduced installation effort.
Wide Temperature Range
Stable performance from −10°C to +60°C, suitable for Saudi Arabia's extreme thermal cycling conditions in both desert and coastal environments.
Chemical Resistance
Resistant to acids, alkalis, oils, and industrial solvents — providing lasting protection in contaminated soil conditions and industrial zones.
Push-Fit Socket System
Integrated push-fit rubber-ring socket joint for fast, tool-free installation. Pre-formed bell ends ensure leak-free, repeatable connections.
Standards
International Standards Compliance
All products in this range are manufactured and tested to the following standards.
BS CompliantISO CompliantEN Compliant
British Standard for uPVC pipes and fittings for buried drains and sewers — covers dimensional requirements and mechanical properties.
