An inversion drum is a type of equipment used in the trenchless rehabilitation of sewer piping. Its main purpose is to facilitate the installation of resin impregnated tube for pipeline rehabilitation.

​

Inversion drums are an essential tool in the installation of Cured-In-Place Pipe (CIPP) lining. The inside of the liner is first vacuum impregnated with a specified resin. The coiled liner is then inflated into the host pipe section under repair. During the process, the liner is inverted (turned inside out) so that the resin-saturated inside is now on the outside and pressed against the pipe’s inner walls.

​

After insertion of the pipe liner, a heating medium (water, steam, hot air, UV, or LED) is run through the pipe and liner to cure the resin to form a permanent bond between the rehabilitated pipe and the liner. The inversion drum allows the operator to control the inversion process by regulating the air pressure and speed of the liner through the host pipe.

​

For the purpose of safety, mobility and saving time and costs, we recommend the Paramount Lining method, using Paramount Inversion Drums as the desirable solution. This method allows for rehabilitation using a single pipe access opening. Paramount Inversion Drums are made of light weight durable aluminum, designed for installation pressures of up to 30 psi and they are available in different sizes – meeting all your project requirements.
