The process involves inserting a high-density polyethylene (HDPE)liner into the steel pipe after controlled diameter reduction. Once installed,the liner expands to form a tight fit against the internal pipe wall, ensuringeffective protection without compromising flow efficiency. The system can beapplied over short to long pipeline sections, including extended pull lengthsdepending on project conditions.

This solution is suitable for both new pipeline installations andrehabilitation of existing pipelines across oil & gas, water, andindustrial applications.
