<strong>Technology</strong>/Method Close Fit PE/Symmetrical Reduction<br />
I. <strong>Technology</strong> Background<br />
Status Conventional<br />
Date <strong>of</strong> Introduction 1985 introduced into the US<br />
Utilization Rates 8,000 miles <strong>of</strong> Tite Liner installed.<br />

Description <strong>of</strong> <strong>Main</strong><br />
Features<br />
The liner pipe is custom sized so that the OD is larger than the ID <strong>of</strong> the host pipe.<br />
The pipe is butt-fused together to the desired length. A roller reduction unit is<br />
placed at the insertion end, while a winch is placed at the other. The winch pulls<br />
the fusion welded liner through the roller reduction unit, which radially<br />
compresses the liner OD during the insertion. Once the liner pipe is completely<br />
through the section to be lined, the tension is released and the Tite Liner expands<br />
radially to fit inside the host pipe.<br />
<strong>Main</strong> Benefits Claimed • Resistant to many fluids<br />
• Structural capability to bridge holes and gaps<br />
• Minimal diameter reduction<br />
• Low coefficient <strong>of</strong> friction<br />
• Minimal site disruption<br />
• Long section lengths<br />
• Low cost<br />
<strong>Main</strong> Limitations Cited • Must be continuous installation without interruption<br />
• HDPE liner thin wall<br />
• Surface damage to HDPE liner during installation<br />
• Interactive – host pipe must have sufficient structural strength to carry<br />
