Project Description
Equinor required a robust and highly precise solution for the rehabilitation of pipe spools with complex geometries. The main technical challenge of the project was the installation of CIPP lining in pipes containing three 90° bends, combined with dimension changes from ID 107 mm to ID 159 mm, as well as ¾" branch pipes with corresponding bends. These conditions placed significant demands on material selection, customization, and execution.
Based on our extensive experience in lining pipe spools since 2008, and our long-standing deliveries to both contractors and oil and gas companies, we were selected as Equinor’s partner for this assignment. The client particularly valued our solution-oriented approach and proven expertise in handling technically demanding projects.
Scope of Work and Execution
The pipe spools were initially sandblasted to SA 2.5 before being treated with a custom-developed epoxy liner, specifically adapted to the dimensional transitions and challenging bend configurations. A functional and reliable solution was developed to reopen and adapt branch connections to smaller dimensions without compromising quality or service life.
The first two insulated spools were delivered during the current month, with the remaining pipe spools scheduled for completion by the end of November.
Result
The project was executed in a professionally sound manner and successfully addressed a technically complex challenge. The delivery resulted in a high-quality final outcome and confirmed our ability to carry out advanced pipe rehabilitation projects with precision, reliability, and consistently high standards.
