Technology/Method Close Fit/Tension - Based, Symmetrical Reduction I. Technology Background Status Conventional Date of Introduction Late 1980s Utilization Rates Over 1,000 miles (1,600 km) of Swagelining have been installed to date. Vendor Name(s) Swagelining Suite 100 600 Bent Creek Boulevard Mechanicsburg PA 17050 USA Phone: 717-724-1900 Fax: 717-724-1901 Web: http://www.swagelining.com Email: info.us@advanticagroup.com Practitioner(s) Licensees provided on website. Description of Main Features • The Swagelining system uses polyethylene pipe, which has an outside diameter slightly larger than the inside diameter of the pipe to be lined. After sections of PE are fused together to form a continuous pipe, the PE pipe is pulled through a reduction die, which temporarily reduces its diameter. • This allows the PE pipe to be pulled through the existing pipeline. After the PE pipe has been pulled completely through the pipe, the pulling force is removed and the PE pipe returns toward its original diameter until it presses tightly against the inside wall of the host pipe. • Swagelining is suitable for the rehabilitation of all types of pressure pipe. Main Benefits Claimed • When the host pipe is structurally sound, the wall thickness of the liner may be reduced. • Since sections of PE pipe are butt fused together, there are no joints where leaks could develop in the future. • Compact, lightweight equipment requires very little setup time resulting in less disruption, faster installation, and less expense. • It is capable of installing the full range of PE pipe quickly and easily in cast iron, ductile iron, steel, concrete and asbestos cement pipelines. • There is no shrinkage or curing and no field chemistry or heating is required. Polyethylene is flexible, leak tight, and highly resistant to chemical attack. Main Limitations Cited • Tension must be maintained on the string of pipe until full insertion is completed. • Work site requires room for a long string of butt-fused pipe sections to be Applicability (Underline those that apply) strung out before diameter reduction Force Main Water Main Forced Sewer Other: Gas, Water Injection Lines, Mining Slurry and any other services using metallic pipe. II. Technology Parameters Service Application Rehabilitation and replacement Service Connections Standard fittings are available to allow sections of PE-lined pipe to be easily and securely reconnected to the rest of your water transmission or distribution system. Wide variety of PE pipes and a full complement of tapping, branching, and connection methods have been developed to provide a total renewal system. Structural Rating Claimed This depends on the PE pipe rating as well as whether or not the PE is to be used as a liner or a replacement for the existing pipe. Materials of Composition Polyethylene Diameter Range, inches 4-44 inches Thickness Range, inches DR 11 to 42 Pressure Capacity, psi This depends on the PE pipe rating as well as whether or not the PE is to be used as a liner or a replacement for the existing pipe.

Technology/Method Close Fit/Tension - Based, Symmetrical Reduction Renewal Length, feet Up to 3,000 feet between excavations. Other Notes Not Available III. Technology Design, Installation, and QA/QC Information Product Standards PE pipe is approved for potable water service in most countries, and can be specified to withstand a wide range of internal pressures and burial depths Design Standards PE pipes used in the Swagelining process are manufactured to ISO, AGA, ASTIVI, and API standards, so lines renewed by this process have known physical properties and an established service life. Design Life Range As per specification of PE pipe used. Installation Standards As per client specifications. Installation Methodology As per sliplining, but the PE pipe is pulled through a die prior to being pulled through the host pipe. QA/QC Not available IV. Operation and Maintenance Requirements O&M Needs Resistant to corrosion, abrasion, and ground movement. Repair Requirements for Standard as PE pipe is used. Rehabilitated Sections V. Costs Key Cost Factors Social & economic cost of open cut replacement versus trenchless rehabilitation of existing pipe lines. List of parameters or key drivers for the costs. Labor, transport, PE prices & delivery, joints (price & delivery), mobilization, pit excavation, cleaning, inspection, gauging, lining, testing, re-connection, site restoration.
