Tite Liner®
Tite Liner is a thermoplastic compression fit liner that can be installed in new or existing infrastructure, safeguarding pipelines for decades to come. Protecting infrastructure with Tite Liner can rehabilitate your pipelines for less than half of the cost and time of dig-and-replace solutions.
Product Highlights
Built To Last
Tite Liner is designed to withstand high temperatures, abrasive chemicals, and can be installed through field bends, providing long-lasting and reliable protection for pipeline infrastructure.
Leak-Free Connections
Tite Liner has been successfully utilized in projects with pressures up to 340 bar (5,000 psi), and has been tested and independently verified to operate with pressures up to 500 bar (7,500 psi).
Long pull lengths
Pull lengths of 2.5 km (8,000 feet) have been achieved, with an average pull length in Tite Liner projects of approximately 600 meters to 800 meters (1,900 feet to 2,600 feet).
Increased Efficiency
Tite Liner’s smooth thermoplastic liner enhances hydraulic performance, compensating for the minor reduction in the pipe’s internal diameter after lining.
Installation Process
1: Access
First, a new or existing host pipeline is sectioned to allow for the insertion of Tite Liner. Individual thermoplastic pipe lengths are joined together by thermal fusion to form long, continuous lengths of liner pipe. A blow-down pig and sizing plate are then attached to a steel cable and sent through a section of the host pipeline.
2: Install
A wireline unit pulls the liner pipe through United’s exclusive powered roller reduction box positioned at the insertion end of the host pipe. The liner pipe is compressed radially as it passes through the roller reduction box. This temporary reduction in diameter provides sufficient clearance between the liner pipe and the host pipe to allow for a controlled insertion.
3: Protect
When the tension is released, the liner pipe expands, creating a tight fit against the inner wall of the steel pipe. Following relaxation of the liner pipe, custom fittings are attached at each end of the lined section. The line is then tested and bolted-up before placing in service.
