What Does Epoxy Pipe Lining Mean?
Epoxy pipe lining is a method of pipeline repair that uses the thermosetting polymer polyepoxide, commonly known as epoxy. Epoxy is a material that can form a permanent seal. The use of epoxy is often paired with other common trenchless rehabilitation techniques to repair cracked, leaky, or otherwise defective pipes and to prolong the lifetime of underground infrastructure.
Trenchlesspedia Explains Epoxy Pipe Lining
Epoxy resins are used in a variety of applications, including paints and coatings, adhesives, industrial tools, and electrical or electronic components. Epoxy is also used for the relining of pipes, and is an effective corrective for spot leaks. Plumbers use an epoxy putty for the quick repair of pipes and plumbing fixtures.
Epoxy pipe lining is used to rehabilitate a pipe from the inside. It is environmentally safe, and the material is often warrantied for 50 years. Cured-in-place piping (CIPP) might be considered a form of epoxy pipe lining because it uses epoxy to bind an inserted tube to an existing pipe. In this case, you might think of epoxy pipe lining as the material rather than the method.
But the use of epoxy alone is often sufficient. An epoxy pipe lining operation starts with the cleaning of the pipe, often with compressed air with an abrasive agent, such as sand. Epoxy is then blown into the pipe, followed by a surge of hot, compressed air to ensure an even coating.
