Cement Mortar Lining (CML)

Cement mortar lining (CML) is a process used to protect the interior of pipelines from corrosion and abrasion. Here’s a general overview of the process:


Before the lining process can begin, the interior of the pipeline must be cleaned and prepared. This may involve sandblasting or other methods to remove any rust, scale, or other contaminants from the surface.


The cement mortar is typically composed of Portland cement, sand, and water. The mixture is prepared according to specific ratios and specifications to ensure the desired consistency and performance.


The cement mortar is then applied to the interior of the pipeline using a centrifugal or spray method. The mortar is applied in multiple layers, each layer being allowed to dry before the next is applied.


Once the cement mortar is applied, it must be allowed to cure for a specified period of time. This may involve a wet or dry curing process, depending on the specifications of the project.


After the curing process is complete, the lining is inspected for any defects or irregularities by Mainline’s team of experts. Any necessary repairs or touch-ups are made before the pipeline is put back into service.

Cement mortar lining is an effective method for protecting pipelines from corrosion and abrasion, particularly in applications where the pipeline is exposed to aggressive chemicals or abrasive materials. It provides a durable, long-lasting barrier that helps extend the life of the pipeline and reduces the need for maintenance and repairs.
