Mechanically Lined Pipe Testing for Corrosive Oil Transport

Simulated Operating Conditions

• Conducted hydraulic expansion of the internal liner to ensure secure mechanical bonding with the outer pipe wall.

• Performed low-grip simulated reeling tests to assess liner stability during installation and operation.

• Applied controlled heat treatment up to 240°C to replicate pipeline coating conditions.

Advanced Testing and Inspection

• Inserted cameras to capture internal diameter (ID) variation throughout bending cycles.

• Performed topography measurements to detect wrinkling or deformation of the liner.

• Conducted hydrostatic pressure testing at 30 bar to evaluate system integrity under load.

• Applied ultrasonic testing to detect hidden flaws and verify liner continuity.

Quality Assurance and Evaluation

• Carried out full visual inspections post-bending, confirming absence of wrinkling or delamination.

• Utilized laser tools and internal video recording to generate detailed inspection reports for each test cycle.
