What is the minimum thickness required for cement mortar lining in pipes sized 14-18 inches?

The minimum thickness required for cement mortar lining in pipes sized 14-18 inches is 3/8 inch. This specification is crucial because it ensures adequate protection of the pipe from corrosion and abrasion, which can significantly extend the life of the infrastructure. Employing the correct thickness also helps maintain the structural integrity of the pipe, reducing susceptibility to cracks or failures, and ensures that the mortar adheres effectively to the interior surface of the pipe.

Using a thickness of 3/8 inch strikes a balance between providing sufficient coverage for protection while not being excessively heavy, which could complicate the installation and operation of the piping system. It’s essential to follow these standards to optimize performance and durability in water works applications.
