Obduramus Circum MINI
For small to medium diameters
The Circum MINI stainless steel rehabilitation sleeve is an internal pipe sleeve which has been technically approved by the DIBt (German Institute for Structural Engineering). It is positioned over the damage using a packer and then pressed against the pipe walls. Enlarging the stainless steel sleeve presses the EPDM seal against the pipe walls and permanently seals the site of lesion.
Advantages of the Circum MINI:
- DIBt approval
- Patented external lock
- No protruding obstacles
- Fully fitted and ready to mount
- Free from environmentally harmful lubricants
- Internal pressure tested up to 16 Bar
The Circum MINI internal rehabilitation sleeve’s patented, external lock ensures minimal cross-sectional reduction in the pipes and prevents passing impediments from becoming lodged. The sleeve is designed for internal pressures up to 16 Bar.
Longitudinal cracks, radial cracks, leaky pipe connections, missing wall sections, closing of unused laterals, replacing missing formwork behind inliners, part formation.
The system was designed to allow the user to install the sleeve themselves without needing to purchase expensive technology. Direct training from us at the site of installation can be provided on request.
