Client Challenge
A leading petrochemical plant in the UAE embarked on a capacity expansion project to meet growing global demand. The increased throughput of aggressive process streams—including hydrocarbon mixtures and high-temperature industrial wastewater—posed a dual challenge:
Corrosion & Integrity Risks: Traditional metallic pipelines were suffering from accelerated degradation, risking leaks and unplanned shutdowns.
Operational Continuity: Any prolonged installation or maintenance window would disrupt production, resulting in significant revenue loss.
The plant required a piping solution that could handle 16-bar pressure, resist chemical attack, dissipate static electricity, and be installed rapidly without interrupting ongoing operations.
The Solution: PE100 HDPE Pipeline System
After a thorough technical evaluation, the plant selected a full PE100 HDPE (High-Density Polyethylene) piping system. The solution included:
Pipes: 12-meter lengths in diameters 630mm, 800mm, 1000mm, and 1200mm, all rated for 16-bar operating pressure.
Fittings: Fully compatible electrofusion and butt-welding fittings designed for high-pressure service.
Material Advantages
Corrosion Immunity: Inert to a wide range of chemicals, eliminating internal and external corrosion.
Static Dissipative: Carbon-black compounded PE100 material prevents static charge accumulation, a critical safety feature in hydrocarbon handling.
Leak-Free Joints: Heat-fused joints create monolithic, permanent bonds stronger than the pipe itself.
Flexibility & Durability: Resistance to ground movement and fatigue, with a design life exceeding 50 years.
Execution: Fast-Track Installation Without Shutdown
The installation showcased the distinct advantages of HDPE:
Minimal Site Preparation: Long 12-meter sections reduced joint count and handling time.
Rapid Welding Techniques: Butt-welding and electrofusion allowed joining speeds up to 5 times faster than flange-by-flange metal pipe installation.
Safe Hot-Tapping: Live plant connections were made using HDPE hot-tap saddles, enabling tie-ins without process interruption or system depressurization.
Reduced Heavy Lifting: Lightweight pipes eliminated the need for large cranes in congested areas, enhancing site safety.
Results & Benefits
Zero Production Loss: All new lines were installed and commissioned without a single hour of unplanned downtime.
Accelerated Timeline: The pipeline installation phase was completed 40% faster than projected for metallic alternatives.
Enhanced Safety: Static dissipative properties and leak-free joints significantly reduced hydrocarbon leakage and ignition risks.
Lifecycle Savings: Elimination of corrosion-related maintenance, lining, and replacement forecasts a 30% reduction in total cost of ownership over 20 years.
Scalability Ready: The modular design allows future capacity increases with minimal additional investment.
Client Endorsement
“The HDPE system was not just a material substitution—it was a strategic enabler for our expansion. It allowed us to add critical capacity safely, at record speed, and without disrupting our production targets. We now consider PE100 the standard for all future corrosive and hazardous service lines.”

Why This Matters for Your Project
In capital-intensive industries where continuity, safety, and speed are paramount, PE100 HDPE pipes provide a future-proof alternative. They combine chemical resistance with structural reliability, install faster, and eliminate recurring corrosion costs—turning pipeline infrastructure from a maintenance liability into a long-term asset.
