Concrete Overweighting by impingement is designed for the construction of underwater pipelines and carried out on pipes already protected with anticorrosion coating.
The pipe, coated with one of the different anticorrosion protections (polyethylene, purtar, bitumen, etc.), is placed on special trolleys and maintained in rotation. At this point, the cement mortar, cast from a hopper, is sprayed onto the pipe and wrapped together with the reinforcement net. The surface is then smoothed by brushes; if the Overweighting thickness requires a double or triple reinforcement netting, the procedure is repeated.
During the Concrete Overweighting operation, all production parameters are recorded and controlled, and the finished pipe is weighed as final step.
Diameter from 6” (168.3 mm) to 60” (1524 mm)
