INSPECTION & TESTING

This article is about Inspection and Testing of Concrete Mortar Lining for Internal Surfaces of Line Piping and Fittings. More you will find about cement lined ductile iron pipe and cement lining pipe Procedure.

what is cement lined ductile iron pipe / Cement Mortar Lining?

Cement lined ductile iron pipe is essentially the same as cement mortar lining. Both terms refer to the process of applying a cement mortar lining to the interior surface of a ductile iron pipe.

A cement mortar liner refers to a protective coating or lining applied to the internal surfaces of steel pipes to provide corrosion resistance and improve the longevity of the pipe. It involves the application of a cement mortar material, which is a mixture of cement, sand, and water, to create a smooth and durable lining on the inside of the pipe.

The cement mortar liner serves as a barrier between the pipe and the transported fluids, preventing corrosion and minimizing the risk of leaks or damage. It is commonly used in various industries, including water supply, sewage systems, and oil and gas pipelines, where the protection of steel pipes against corrosion is crucial.

The cement mortar liner is applied through a specialized process that includes surface preparation, application of the mortar mixture, and curing. The thickness of the liner can vary depending on the specific requirements and conditions of the pipeline. The liner enhances the structural integrity of the pipe and helps to maintain the quality and efficiency of fluid transportation.
