New Research on Mechanically Lined Pipe Behaviour Published in Journal of Pipeline Science and Engineering

A new research paper titled “Experimental and Numerical Investigation into the Influence of Galling on Liner Wrinkling Behaviour in Mechanically Lined Pipes” has been published in the Journal of Pipeline Science and Engineering.

The study was carried out through a collaboration between Cladtek, The University of Western Australiae Curtin University, with Dr.Ahmed Reda, New Technologies Manager at Cladtek, contributing to the research and technical supervision.

The paper became available online in March 2026.

Improving Understanding of Mechanically Lined Pipe Performance

This research focuses on how Mechanically Lined Pipes (MLPs) behave when pipelines are bent during installation or operation.

Using a combination of full-scale testing and engineering modelling, the study examines how small surface features that can occur during manufacturing, known as galling, may influence when liner wrinkling begins.

The findings help our engineers better understand how these surface features affect pipe performance and how inspection results should be interpreted.

What This Means for Pipeline Projects

For operators, contractors and engineering teams, the research provides better technical understanding when assessing manufacturing quality and inspection results.

This supports more informed decisions during pipeline design, qualification and project evaluation, while maintaining confidence in the structural performance of corrosion-resistant mechanically lined pipe systems used in offshore developments.

The work also reflects Cladtek’s capabilities in engineering research, testing and modelling, supporting the continued development of lined pipe technology for demanding offshore applications.

The publication contributes to the broader industry understanding of lined pipe behaviour and supports ongoing research in pipeline engineering.
