Pipe rehabilitation system

Pipe repair sleeves for trenchless pipe rehabilitation. Protects resources and the environment.

Pipe repairs using sleeves

Gapless sealing

Obduramus Umwelttechnik GmbH has developed a locking mechanism for Circum products in order to quickly and effectively repair pipe connections from DN 150 and up. This system is flexible and manufactured using high-quality materials. Lock rings and/or stainless steel sleeves are enclosed by EPDM seals and are kept pressed against the inner pipe walls using specially developed and patented tension locks. This system seals the damaged spot 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 for all components, resulting in no corrosion

Fast and simple installation saves time

Installation with no environmentally harmful chemicals
