HDPE & PE-RT Tight Fit Lining for Pipeline Rehabilitation
Scorpion Arabia delivers advanced HDPE and PE-RT tight fit lining solutions to rehabilitate aging pipelines, prevent corrosion, and extend service life without full pipeline replacement.
HDPE and PE-RT tight fit lining is a trenchless pipeline rehabilitation method used to restore and protect existing pipelines from the inside.
The process involves installing a high-performance polymer liner inside the host pipe, creating a close-fit internal barrier that protects against corrosion, abrasion and chemical attack. Once installed, the liner forms a continuous, joint-free surface that improves flow performance and extends the operational life of the pipeline.
Scorpion Arabia delivers tight fit lining solutions for pipelines where replacement is impractical, costly or disruptive.
Many pipelines remain structurally sound but suffer from internal corrosion, scaling, leakage or reduced flow capacity. Full replacement in such cases often results in unnecessary cost, downtime and surface disruption.
HDPE and PE-RT tight fit lining provides a cost-effective, low-disruption alternative by rehabilitating the pipeline internally while keeping the existing asset in place.
Key challenges addressed by tight fit lining include:
- Internal corrosion and material degradation
- Reduced hydraulic performance
- Leakage and pressure loss
By lining instead of replacing, operators protect their investment and restore performance with minimal operational impact.
How HDPE / PE-RT Tight Fit Lining Is Installed
Scorpion Arabia applies a controlled and proven installation methodology to ensure reliable liner performance.
Pipeline Assessment & Cleaning
Inspection and cleaning of the host pipe to prepare it for lining.
Liner Preparation
HDPE or PE-RT pipes are butt-fused to form a continuous liner string.
Diameter Reduction & Insertion
The liner is temporarily reduced and pulled into the host pipe.
Liner Reversion
Once in position, the liner reverts to its original diameter, forming a tight fit against the host pipe.
End Connections & Testing
Final connections and pressure testing to confirm integrity and performance.
Scorpion Arabia’s tight fit lining solutions are suitable for a wide range of pipeline sizes and applications.
Typical parameters include:
- Pipe diameters from small to large utility sizes
- Underground and above-ground pipelines
- Short and long pipeline sections, subject to site conditions
Applications include:
- Water transmission and distribution
- Gas pipelines
- Industrial and process pipelines
- Utility and infrastructure networks
Each project is evaluated to confirm technical suitability before execution.
HDPE and PE-RT tight fit lining is often used as part of a broader pipeline strategy.
At Scorpion Arabia, lining works are coordinated with:
- Pipeline construction and upgrades
- Trenchless installations and crossings
- Composite wrapping and external protection
- Soil stabilization and casing systems
This ensures a consistent, end-to-end approach to pipeline integrity.
All tight fit lining works are executed under controlled procedures and strict quality standards.
Scorpion Arabia ensures:
- Proper liner fusion and installation control
- Compatibility with operating pressure and temperature
- Testing and verification before commissioning
Our focus is on delivering reliable, long-term performance, not temporary fixes.
