The oil and gas industry relies heavily on pipelines for efficient transportation of resources. Internally coated pipelines offer numerous advantages, including enhanced corrosion resistance and improved flow characteristics. However, tie-ins for these pipelines present unique technical challenges. In this blog, we will highlight a recent project where the Lined Pipe Systems team provided on-site expertise to a client facing such challenges, ensuring a successful tie-in for their internally coated pipeline.
Internally Coated Pipelines
Internally coated pipelines feature a protective layer applied to the inner wall of the pipe. These coatings can be made of various materials like epoxy resins, polyurethanes, and thermoplastics. The specific coating chosen depends on the intended application and the substances being transported.
Challenges of Tie-Ins for Internally Coated Pipelines
While internally coated pipelines offer significant advantages, tie-ins present unique challenges. Here’s why:
Maintaining Coating Integrity
During tie-in procedures, the internal coating can be damaged by welding, grinding, and other mechanical activities. This damage can compromise the pipeline’s corrosion resistance and overall integrity.
Surface Preparation
The internal surface of the existing pipeline and the new tie-in section require meticulous preparation to ensure proper adhesion of the coating. This preparation involves cleaning, roughening, and removing any contaminants.
Coating Selection and Application
Selecting the right coating material and applying it flawlessly within the confined space of the pipeline are crucial for successful tie-in.
Quality Control
Ensuring proper coating thickness, adhesion, and overall quality throughout the tie-in process requires stringent quality control measures.

Benefits of Internally Coated Pipelines
Corrosion Resistance
The primary benefit of internal coatings is superior resistance to corrosion, a major threat to pipeline integrity. This translates to extended pipeline life and reduced maintenance costs.
Improved Flow
Internal coatings create a smoother surface, reducing friction and enhancing flow efficiency. This translates to lower pumping costs and increased throughput.
Versatility
Internally coated pipelines can handle a wider range of products, including corrosive fluids and erosive slurries.
