EX Pipe is a high strength, un-plasticized PVC manufactured in a factory<br />
environment, meeting ASTM F1504. The EX Pipe material is s<strong>of</strong>tened with heat<br />
and continuously inserted into the host pipe via manholes or other access points.<br />
After insertion, the pipe is then expanded approximately 10% to fit tightly within<br />
the host pipe.<br />
<strong>Main</strong> Benefits • Resistant to chemicals and abrasion<br />
Claimed • Stops water infiltration and exfiltration, root intrusion and soil loss<br />
• Smooth pipe finish improves flow characteristics<br />
• Cost to install EX Pipe is much less than conventional trenching techniques<br />
• No styrene odors<br />
• Low coefficient <strong>of</strong> thermal expansion means service cut-outs will not move<br />
<strong>Main</strong> Limitations<br />
