Equipment Spotlight
Rehab Focus: Lining Systems
LMK Technologies
LMK’s T-Liner is a one-piece homogenous main and lateral CIPP connection liner that is ASTM F2561 compliant. Both the mainline and lateral sections are formed as a structural cylinder that renews 18-inches and 360 degrees of the mainline and extends up the lateral pipe as one continuous lining with uniform wall thickness. T-Liner with Insignia compression gasket-sealing technology between the host pipe and the T-Liner provides a verifiable non-leaking system. 815.433.1275, http://www.lmktechnologies.com/t-liner
National Liner
The National Liner CIPP product starts with a tube made from non-woven needled polyester felt material. The tube is vacuum impregnated with a thermosetting resin that has excellent corrosion resistance and physical properties. Once inserted into the pipe, it is expanded and cured, forming a smooth, continuous pipe inside the host pipe. This continuous length liner will help to eliminate groundwater infiltration. The felt manufactured for National Liner can be installed with a wall thicknesses ranging from 4.5 mm to 60 mm, for pipe ranging from 6 to 120 inches in diameter. 800.547.1235, http://www.nationalliner.com
Pipenology
Pipenology liners are manufactured to the sizes specified by the customer, ranging from 6 to 96 inches in diameter. The liners use TechniFelt to ensure consistency in strength and resin absorption. The outside layer is coated with Pipenology’s unique EnduraCoat, a proprietary polymer blend that enhances flexibility, minimizes friction and is compatible with either a hot water or steam cure. Seams are butt-sewn with the finest thread and then extrusion sealed to exacting standards. Pipenology’s multi-step quality assurance process is conducted on-site, to ensure that the liner is free of dry spots, lifts and delamination of any layers or tube coating. 636.542.6710, http://www.pipenology.com

Perma-Liner Industries
With Perma-Liner Main Lining System for municipal main line sanitary sewers, certified, third-party tested equipment and materials are engineered and manufactured to meet project specifications on an individual basis. The cured-in-place felt liners are produced with different thicknesses to meet the varying pipe diameters and individual sizes of municipal city lines. Upon insertion of the resin impregnated felt liners into the existing host pipe, the resin hardens and creates a structurally lasting pipe within a pipe. A robotic camera then goes in to check the work, and ensure the insertion process was successful. Perma-Liner products extend the life of your existing pipes by at least 50 years, leaving a minimal carbon footprint. 866.336.2568, http://www.perma-liner.com

IPR
Depending on site conditions and project specifications, IPR offers two CIPP liner systems for gravity-flow sewers and culverts. For standard installations, IPR offers an Isophthalic resin-based liner technology system, and for stricter requirements in harsher environments, an advanced epoxy-based lining system features eco-friendly Dow epoxy resins. Pipe diameters range from 6-144 inches (standard) and 6-42 inches (advanced) for all types of pipe materials. IPR CIPP liners meet or exceed the ASTM standards for CIPP pipeline rehabilitation. 281.362.1131, http://www.teamipr.com
Fibrwrap Construction
The Tyfo Fibrwrap Pipe Rehabilitation System is a fiber reinforced polymer (FRP)-based, trenchless technology method for the repair, strengthening and retrofit of corrosion-damaged and distressed large-diameter PCCP, RCCP, and steel pressure pipelines ranging from diameters of 36 to 201 inches. Fibrwrap offers a complete, turnkey package that includes access, surface preparation and application of the Tyfo Fibrwrap system. The entire Tyfo system is NSF 61 compliant, and when necessary, additional protective coatings are applied for aggressive chemical or environmental exposures. 636.530.3316, http://www.fibrwrap.com
Inliner Technologies
The Inliner product is installed using direct inversion as well as the pull-in method for deteriorating pipelines ranging in diameter from 4 to 120 inches. The curing process can be completed by either hot water or steam/hot air. This transformation of a soft, flexible felt tube to a thermoset resin-impregnated liner and finally to a cured structural liner within the existing pipe is a process for which Inliner crews and project managers have been trained to ensure compliance with the owner’s required specifications. 812.723.0704, http://www.inliner.net
Miller Pipeline
The MPC ToughTube CIPP lining system restores structural integrity, reduces inflow and infiltration, and in many circumstances increases flow capacity in larger diameter lines. The pliable nature of the uncured pipe liner, made of a resin-saturated felt with a vapor barrier, allows the material to be installed around curves and other obstructions while filling cracks and bridging gaps. Once the resin-impregnated tube has been fully installed, it is cured using circulating hot water or steam. After the tube has cured into a monolithic structure, the laterals are robotically reopened. It is available in a wide variety of shapes and pipe diameters from 6 to 96-plus inches. 800.428.3742, http://www.millerpipeline.com
