Pipe rehabilitation system

Rehabilitation sleeves for repairing sockets without groundwork. Protects resources and the environment.

Pipe repairs using sleeves

Gapless sealing

Obduramus Umwelttechnik GmbH had developed a locking mechanism for Circum products in order to quickly and effectively repair pipe connections from DN 150. The system is flexible and manufactured using high-quality materials. Lock rings and/or stainless steel sleeves are placed inside the EPDM seals and are pressed against the pipe walls using specially developed and patented tension locks. This seals the damage permanently and reliably.

Their benefits:

Permanent sealing purely based on the principles of mechanics

Effective and sustainable repairs

Stainless steel sleeve manufactured using the same grade of steel, resulting in no corrosion

Fast and simple installation saves time

Installation with no environmentally harmful lubricants
