1. What Is Insituform Technologies, Inc.?
Insituform Technologies, Inc. is a leading provider of trenchless pipeline rehabilitation and replacement solutions. According to research from the University of Texas at Arlington’s Center for Underground Infrastructure Research and Education (CUIRE), trenchless technologies like those used by Insituform can reduce infrastructure project costs by up to 30% compared to traditional methods. The company specializes in the Insituform CIPP (Cured-In-Place Pipe) process, a method that involves inserting a resin-saturated liner into an existing damaged pipe, which then hardens to form a new pipe within the old one.
1.1. The Insituform CIPP Process Explained
The Insituform CIPP process is an innovative method for rehabilitating aging or damaged pipelines without the need for extensive excavation. The key steps include:
- Inspection: A thorough inspection of the pipeline using CCTV cameras to identify the extent of the damage and any obstacles.
- Cleaning: Removing debris, scale, and other obstructions from the pipe interior using high-pressure water jets or mechanical cleaning tools.
- Liner Insertion: Inserting a flexible liner, custom-made to fit the dimensions of the existing pipe, saturated with a thermosetting resin.
- Curing: Curing the resin-saturated liner using steam, hot water, or ultraviolet (UV) light, causing it to harden and form a new, seamless pipe within the old one.
- Final Inspection: Conducting a final inspection to ensure the integrity of the new pipe and reinstate any lateral connections.
This trenchless technology offers several advantages, including minimal disruption to surface traffic and businesses, reduced excavation costs, and extended service life of the rehabilitated pipeline.
