Since 1985 United has been a global leader in high-performance thermoplastic internal pipeline lining systems for pipeline integrity.

We have installed over 16,000 miles of the Tite Liner® system from 2 inches to 52 inches in diameter with operating pressures up to 7,500 psi in more than 30 countries worldwide.

Whether protecting new pipelines from corrosion and abrasion or rehabilitating existing pipelines, we combine high-quality, innovative solutions with unparalleled expertise, service and safety.



Case Studies

We work around the world lining critical pipelines for the oil & gas, industrial, mining and municipal markets. Check out the case studies below to see how the Tite Liner® system has been implemented for a variety of applications.

Markets We Serve


Oil & Gas

Eliminate internal corrosion from the perforation to the processing facility. The material properties of the Tite Liner® system provide excellent chemical, corrosion and erosion resistance for numerous oil & gas pipeline applications.



We work throughout the world to safeguard mining infrastructure by extending its life and help meet regulatory requirements. Our Tite Liner® solution helps to prevent corrosion and erosion to help ensure the integrity of these critical pipelines.




United Pipeline Systems has been installing industrial pipe liners for nearly 20 years. The Tite Liner® system, a high-density polyethylene pipe liner, is particularly well-suited to provide protection against pipeline corrosion and abrasion to chemical pipelines.
