Obduramus Circum MINI

For small to medium diameters

The Circum MINI stainless steel rehabilitation sleeve is an internal pipe sleeve which has been approved by the DIBt (German Institute for Structural Engineering). It is positioned over the damaged spot using an inflatable packer and then pressed against the pipe walls. Expanding the stainless steel sleeve presses the EPDM seal against the inner pipe walls and permanently seals the damaged spot.

Advantages of the Circum MINI:

DIBt approval
Patented external lock
No protruding obstacles
Packer-protecting
Fully fitted and ready to mount
Free from environmentally harmful lubricants
Internal pressure tested up to 16 Bar

Feature

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 pipe pressures of up to 16 Bar (225psi).

Application

Longitudinal cracks, radial cracks, leaky pipe connections, missing wall sections, closing of unused laterals, replacing missing formwork behind inliners, part formation.

Service

The system was designed to allow the user to install the sleeve themselves without the need to purchase expensive technology. On-site training provided by us can be provided upon request.
