CIPP Lining Manufacturing from the Industry Leaders at Applied Felts

The cured-in-place pipe (CIPP) liner was a revolutionary invention in the world of gravity sewer line, pressurized, and water potable pipe repair, consisting of a resin-soaked felt with an impenetrable, polyurethane-coated exterior.

During CIPP installation, the liner adheres seamlessly to the interior of the damaged host pipe, creating a pipe-within-a-pipe. It’s a quick, cost-effective alternative to traditional pipeline rehabilitation methods like digging large-scale trenches or open-cut repair.

Existing pipelines that are leaking, broken, or malfunctioning not only pollute the environment but they’re wasteful, costly, and downright dangerous. Using a CIPP liner is not only safer than open-cut repair, but it’s also cheaper, faster, and less disruptive to the community and surrounding environment.

As a CIPP liners manufacturing company that’s well-established and respected within the industry, we are proud of the innovative process we use to produce our liners, including 28-stage quality assurance testing. What makes our manufacturing and CIPP installation process the gold standard for cured-in-place pipe manufacturers around the world? Let’s find out:

Initial Inspection: The raw materials we use undergo a rigorous inspection and testing method to ensure strength, durability, and premium quality. Our liners consist of felt, polyester, polyurethane, and resin.

Five-Stage Production: After we select the highest-quality felt and discard the rest, we use a five-stage production process, testing for strength, flexibility, density and thickness, fiber distribution, and overall weld-ability.

Single-Pass Felt Coating: Our exclusive “single-pass” felt coating process eliminates any pinholes, but we still perform four separate tests to ensure that the coating is uniform and evenly distributed for a flawless finish.

Multi-Step Testing: Post-coating, each felt roll undergoes even more testing. We sample and destruct each liner to test its quality using nine unique characteristics, including coating distribution, tensile strength, and density under pressure. Our staff conducts these tests continually during each phase of the manufacturing process, ensuring that each CIPP liner has the exact specs needed for its intended application.

Post-Production Quality Assurance: Even after we finish the manufacturing process, our CIPP liners undergo still more testing across seven criteria to ensure superior quality, including weld strength, coating integrity, diameter and length, density, and more.

Why do we use such a meticulous and exacting testing process for our CIPP liners? It’s simple: we go above and beyond for every client to ensure that our CIPP lining not only meets but exceeds their specifications.
