Technology/Method Symmetrical Reduction PE Close Fit Liner I. Technology Background Status Emerging Date of Introduction 2001 in US Utilization Rates Total HDPE experience worldwide - over 8000 miles. Vendor Name(s) InsituGuard TM Flexed HDPE Insituform Technologies, Inc 17999 Edison Avenue Chesterfield, MO 63005 Phone: 800-234-2992 Fax: 636-519-8744 Web: http://www.insituform.com/ Practitioner(s) Not available Description of Main Features Inserted into a new or existing pipeline, the polyethylene liner is continuous, and installed with a close-fit against the inner wall of the host pipe. The polyethylene liner isolates the flow stream from the host pipe wall, eliminating internal corrosion. InsituGuard stops leaks, and can provide a fully structural solution in some cases. Main Benefits Claimed • Rapid installation • Drinking water approved • Negotiates long radius (sweep) bends • Utilizes high-performance PE 100 (4710) • Minimizes disruption Main Limitations Cited • Cannot do factory bends (20% diameter reduction to facilitate introduction) Applicability (Underline those that apply) • Bypass required Force Main Gravity Sewer Laterals Manholes Appurtenances Water Main Service Lines Other:__________________________ II. Technology Parameters Service Application Rehabilitation Service Connections Service Connections have to be excavated. Fused fittings used to reinstate. Structural Rating Claimed Class 3 or 4 depending upon diameter, pressure and host pipe condition. Materials of Composition 4710 (PE 100) Diameter Range, inches 6 to 48 inches Thickness Range, inches DR 17 or thinner Pressure Capacity, psi Pressure rating to 150+ psi for Class 3. Class 4 dependent upon DR. Temperature Range, o F 140 o F Renewal Length, feet 2000+ feet depending on winching capacity. Other Notes Pipes may be cleaned, as needed, with high-pressure water jet cleaners, mechanically powered equipment, and winch cable attached devices or fluidpropelled pig devices. III. Technology Design, Installation, and QA/QC Information Product Standards HDPE is certified as complying with ANSI NSF Standard 61. Design Standards Class 4 design based on AWWA/PPI design standards. Class 3 interactive design based on industry accepted design methodology. Design Life Range 50 years Installation Methodology 1. Excavations are required for installation and to remove any existing fittings. 2. The PE pipe selected for the project is welded into lengths suitable for installation; this can be the entire length, or shorter segments to accommodate available work space. If shorter segments are used, they will be fused together prior to entering the roller reduction machine. 3. The welded pipe is pushed through the roller box, which alters the shape of the pipe, resulting in a diameter reduction of up to 20% of the cross-sectional area. 4. The liner is inserted into the host pipe. 5. Once the liner is in place, it is cut to length, end fittings are attached and the liner is pressurized to snap the bands. 6. Intermediate fittings are installed, service connections are excavated and A-10
Technology/Method Symmetrical Reduction PE Close Fit Liner reconnected, and the completed line is pressure tested, disinfected and returned to service. Access points are backfilled and reinstated. QA/QC • Prior to installation of InsituGuard, CCTV inspection of the main is needed to locate any obstructions, protrusion, changes in diameter or in-line valves that could affect the InsituGuard. • After installation, InsituGuard is inspected again visually with CCTV, and any abnormalities are noted. • For the post-installation pressure test, InsituGuard is subjected to an internal pressure equal to twice the known operating pressure, or operating pressure plus 50 psi, whichever is less. • After a stabilization period, the test period is one hour. Limit on make-up water to maintain pressure is 20 gallons per inch diameter per mile of pipe per day. IV. Operation and Maintenance Requirements O&M Needs Before returning the InsituGuard to service, for potable water, the system shall be Repair Requirements for Rehabilitated Sections disinfected in accordance with local standards. Excavate, remove the damaged portion of InsituGuard and host pipe (if necessary), install end couplers and bridge the previously damaged location with new pipe and couplers as required. V. Costs Key Cost Factors The most costly material is the pipe. Case Study Costs Not available VI.
