Unique Liner Features

Click the tabs below to learn how our materials and processes create a state-of-the-art liner:

LinerBackgroundB&WWe coat our liners with a proprietary polymer blend developed to enhance flexibility, lower small diameter installation pressures, be compatible with either a hot water or steam cure, while optimizing the performance characteristics of the installed product. This coating is key  to a quality installation, cure and the long-term integrity of the CIPP. No other liner manufacturer offers this unique polymer blend for their liner coating

TechniFeltPhotoTo meet the short-term and long-term performance requirements for CIPP, the felt must absorb resin quickly and evenly, retain it throughout the installation and cure, and have superior dimensional stability throughout these processes. Pipenology has chosen the finest technical felt, superior to the felt used by others, because of its uniform polyester felt fiber distribution, absorption and retention of the thermoset resins, resulting in an enhanced consistency of the final product.

IronStichForBannerOur combination of detailed stitching with an extruded seal creates a seam that is both extremely strong and flexible. This combination of attributes makes our liner the best choice for the toughest installation environments.

Making Liners To Satisfy You AND Your Customers

We produce to exacting specifications in our ISO 9001: 2015 certified manufacturing plant.  The sewn liners meet or exceed all ASTM standards.  Pipenology liners are manufactured to the sizes specified by the customer, ranging from 6 inches to 96 inches in diameter. Our liners use our TechniFelt™, considered the highest quality felt available, 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.  For extra strength and flexibility, seams are butt-sewn with the finest thread and then extrusion sealed to exacting standards. Our 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. In the end, our quality is best judged by the satisfaction of our customers who ultimately benefit from our liner’s ease of installation, durability and performance.

Whatever your project needs – large or small diameter, challenging specs, tight schedule – we deliver using the latest proven technologies. We partner with you to make sure you get the right liner solution to make your project a success.”  Jim Hock
