Cement mortar lining

CM lining

The main function of a pipe lining is to protect a pipeline reliably and durably against corrosion attack from aqueous media. Depending on the degree of hazard involved, various mortar linings are available.

The standard components of cement mortar are cement, dried quartz sand, and drinking water. With the aid of an impeller powered by an air motor, the mortar is centrifuged against the pipe wall and then smoothed down and compacted in a rotary station at a defined speed. The speed of pipe rotation is selected to ensure maximum compaction and a homogeneous microstructure, while preventing the accumulation of fine-grain sediments on the pipe inside surface.
