2. Primer Application

A specialized primer is applied to promote bonding between the steel surface and the coating material.

3. Coating Application

Depending on project requirements, we use heat-shrink sleeves, liquid epoxy, polyurethane, or polypropylene systems—each selected for its durability and compatibility with the parent coating.

4. Inspection and Testing

Every joint undergoes rigorous testing for thickness, adhesion, and continuity. Our technicians ensure zero defects before the pipeline is commissioned.

The Keldori Advantage

With over a decade of experience in pipeline protection, Keldori Services Limited delivers FJC solutions that meet international standards and exceed client expectations.
