Trenchless Technology Product Overview
ALL trenchless rehabilitation solutions have inherent strengths and limitations. For example, there are pressure rated systems that are capable of spanning miles without requiring access but require a significant footprint for staging or installation. Others are solely liners and intended to repair tight radius bends or fittings while relying on the structural integrity of the existing host pipe. The material and installation cost of these technologies can greatly vary depending on each application. Additionally, some pipe lining solutions can be installed in a matter of hours while others may take days. Several factors (such as budget, flow requirements, pressure handling capabilities, host pipe diameters & material, and many more) NEED to be evaluated when selecting the most suitable trenchless rehabilitation solution.
Product Description
Trenchless Rehabilitation Solutions | How it Works |
|---|---|
CIPP (Cured-In-Place-Pipe) Pressure & Non-Pressure Rated | Involves inserting a resin-saturated felt tub in the host pipe. After the tube has been installed inside the existing pipeline, it is then pressurized and cured. |
Pressure Rated | Involves using a cutting tool attached to the front of new pipe that is pulled through and simultaneously breaks apart the existing host pipe. HDPE & PVC are the most commonly used materials. |
SIPP (Sprayed-In-Place) Pressure & Non-Pressure Rated | Involves spraying a coating onto the inside wall of the host pipe. |
Pressure Rated | Involves installing a smaller diameter liner pipe inside a large diameter host pipe. Types of liner pipe materials include HDPE, PVC, FRP, nylons, composite piping, fire hose style liners, steel, and more depending on operational requirements & budget. |
Swagelining or Compressed Fit Pressure & Non-Pressure Rated | Involves radially compressing liner pipe that has a diameter equal to or larger than the inside diameter of the host pipe with a static die or roller reduction box. While the liner is compressed, it is pulled through the host pipe. Note: HDPE is the most common material but Nylons and other materials are available. |
