Liner Products manufactures quality CIPP lining tubes for use with both of the predominant installation techniques used in the industry today: the direct inversion method and the pull-in-place method utilizing a stay-in-place calibration hose. All CIPP lining tubes comply with applicable ASTM standards, including ASTM D-5813, ASTM F-1216, and ASTM F-1743.
All products are designed and built to our stringent Manufacturing Specifications and are tested in accordance with our ISO 9001:2001 certified quality system.
Each CIPP lining tube is individually designed and manufactured to meet the customer's specifications. We manufacture diameters in 1/8 inch increments from 3 to 144 inches. Standard tube thicknesses are built in 1.5 mm increments — but we also offer a variety of nonstandard tube thicknesses to best fit a particular requirement. We can construct virtually any tube length and can splice multiple tube lengths together, in the field if necessary, if the entire length is too large to transport.
We also can custom design and manufacture special-use CIPP tubes for unique applications and unusual installation requirements.
We invite you to download our Product Specifications and Product Information Manuals for our pull-in-place and direct inversion lining tubes. Please supply the user information requested below to access the manuals you would like.
We also manufacture a variety of quality accessories to help you complete your installations more effectively and efficiently. Just as with our lining tubes, fabrication of these ancillary items is performed under our quality system to ensure adherence to the highest standards.
Soft Ends
A soft end watertights the trailing end of a direct inversion tube and provides one or more handle(s) onto which holdback rope(s) and circulation hose(s) can be attached. An integrated "burp" device permits resin to be pumped into the tube during wetout and allows air trapped within the tube to be released during installation.
Inversion Columns
An inversion column is a specifically reinforced, three-layer tube which spans the vertical reach down the access point (e.g., a manhole) to the pipe and which is used to build the desired water head or air pressure to invert, inflate, and expand a calibration hose or direct inversion tube during installation.
Tailored Down Tubes
A section of direct inversion tube which is specially tailored to accommodate the size of the access point (e.g., a manhole) and which spans the vertical distance from the beginning of the inversion to the pipe to be lined. Like an inversion column, this section is used to build and maintain the desired water head or air pressure during installation.
Starter Ropes
Starter ropes are strung through the down tube section of a direct inversion tube and fixed to the tube to assist in turning the tube horizontally into the pipe.
Pull Tapes
A pull tape, which is incorporated throughout the entire length of the tube during manufacture, is used to assist the inversion of very small diameter tubes (typically six inches or less).
