What is the minimum thickness required for cement mortar lining in pipes sized 4-12 inches?

The minimum thickness required for cement mortar lining in pipes sized 4-12 inches is 5/16 inch. This specification is in place to ensure that the lining provides adequate protection against corrosion and wear while also maintaining the structural integrity of the pipe. A thickness of 5/16 inch strikes a balance between strength and weight, ensuring effective insulation and durability without becoming unnecessarily heavy or difficult to work with. This thickness helps to achieve a smooth internal surface, which is crucial for minimizing friction and ensuring efficient water flow within the pipeline.

Adhering to this specification is important for compliance with industry standards and regulations, which often dictate the requirements for materials used in water distribution systems. In contrast, thinner linings may not provide sufficient protection, while linings that are too thick could lead to increased costs and complications during installation and maintenance.
