System Overview

The Tite Liner® System is the world's leading polyethylene lining system for internally protecting pipelines from abrasion and corrosion. The Tite Liner System utilizes a polyethylene liner pipe that comes in sizes from 2" to 48" in diameter. The Tite Liner System protects pipelines from a variety of chemicals and abrasives, through a broad range of temperatures and pressures.

Host Pipe Strength - Plastic Liner Barrier
The Tite Liner System combines the strength of a steel pipeline with the exceptional corrosion and abrasion resistance of polyethylene.

The polyethylene liner isolates the flowstream from the host pipe wall, eliminating internal corrosion. The Tite Liner System is ideally suited for corrosive and abrasive applications such as water lines, crude oil lines, slurry lines, wet gas lines, and effluent lines.

Unlike other lining processes, the Tite Liner System places the liner in tight radial contact with the inside of the host pipe. Pulled into a new or existing pipeline by our proprietary installation process, the polyethylene liner is thick, continuous, and installed tightly against the inner wall of the host pipe.

The polyethylene pipe utilized in the Tite Liner System exhibits superior mechanical and chemical properties through all pressure and temperature ranges up to 82 Celsius (180 Fahrenheit) with many fluids. For higher temperatures or more aggressive fluids, United can recommend alternative lining materials.

In order to respond quickly to customer needs and project requirements, we’ve established manufacturing and construction support facilities in four countries. United maintains a high standard of quality and dimensional tolerance by designing and manufacturing our proprietary installation equipment and key project components such as flange connections, polyethylene flange-fittings, spacer rings and special fabrications. Retaining control of the manufacturing schedule allows us to keep our delivery commitments. In addition to manufacturing key components in-house, we also conduct development and product testing.

United approaches each pipeline construction project as a custom undertaking, designating a specific liner size, flange-fittings and installation equipment for the job. When the installation of a Tite Liner System is complete, we thoroughly test and inspect the entire pipeline to ensure that the system has been properly installed and is functioning according to the system design.
