Miller Pipeline

The MPC ToughTube CIPP lining systems restore structural integrity, reduce inflow and infiltration, and in many circumstances increase flow capacity in larger diameter lines. The pliable nature of the uncured pipe liner, or tube, which is 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. The lining process is accomplished by either inverting or pulling the tube into the existing host pipe made of any material. Once the resin-impregnated tube has been fully installed, it is cured using circulating hot water or steam. During the curing process, the tube is held tightly against the host pipe by internal pressure. 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-inches to over 96-inches. 800.428.3742, millerpipeline.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 four to 120 inches. The curing process can be completed by either hot water or steam/hot air that allows for versatility when scheduling projects, crews and equipment to complete each CIPP project. 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, inliner.net

Reline America

The BLUE-TEK liner is both a glass fiber reinforced pipe (GRP) and a UV cured-in-place (CIPP). The liners are manufactured based upon the type of site and required chemical-resistance. Generally, industrial sewage requires a more chemically resistant liner than those used in public sewer systems. Reline America has the flexibility to adapt its product to meet the demands of the specific application and ensures that the products are manufactured according to the required criteria. 866.998.0808, relineamerica.com
