Pipe Cement Mortar Lining Plant

Cement mortar has been used to line pipe for several decades. This process allowed the rapid application of linings to the entire pipe surface by placing a mixture of sand, cement and water into the pipe and rotating it at high speed. The centrifugal forces distribute the lining around the pipe circumference and compact it against the pipe wall. At the same time excess water is spun out, leaving a smooth surface mortar, with a very low water to cement ratio. Together with the low void content this results in a strong, low permeability cement mortar lining. Note these linings perform much better than cast concrete, due to the high cement content, low void content, and low water content of cement mortar.

Cement mortar linings (CML) provide demonstrated long-term protection at a low cost, and consequently they remain the standard lining for potable water pipes. Alternative linings, such as liquid applied epoxy, have not gained as widespread acceptance because of concerns that they do not provide the longevity required for water supply pipelines. A major benefit with cement mortar is the ease of application. The mixing and application of mortar is straight forward, leading to low risks in application. This is a significant advantage over epoxy linings, that require careful control of ambient conditions, mix ratios, curing, etc.
