ELECTRO-MAGNETIC SCANNING OF PRE-STRESSED CONCRETE PIPES

The pipe can be scanned even when it is up to 40% full of water; Pre-stressed concrete Pipelines of 700mm till 4000mm can be scanned; Analyzing Tool enables instant results – facilitate marking of damaged areas during scanning operations; Not only categorize the classes of wire breaks but also quantify down to a single wire break; Between two and ten kilometres can be scanned per day

CARBON FIBRE REPAIRS

Non-invasive repair method. Internal as well as external repairs are possible. External repairs can be performed when the pipelines are still under pressure. Due to the inherent properties of carbon fibre and our vacuum epoxy infusion technology, reductions in diameter of pipes due to the repair are minimized. An optimal carbon fibre – epoxy ratio of 60/40 can be obtained. An equal and homogeneous end product is obtained. In PCP pipelines, the condition of the pre-stressed wires can still be monitored after carbon fibre repair. There is a safety factor of three.
