Cement mortar lined pipe fittings are a type of pipe fittings that have an internal lining of cement mortar to provide protection against corrosion and erosion. The cement mortar lining is a thin layer of cement-based material that is applied to the inner surface of the pipe fittings to create a smooth and durable barrier that protects against the corrosive effects of water and other fluids.

Cement mortar lined pipe fittings are commonly used in water and wastewater applications where the pipes are exposed to corrosive fluids. They are particularly effective in reducing the risk of corrosion in steel pipes and fittings, which are commonly used in water distribution systems.

The cement mortar lining provides a protective barrier that is resistant to the corrosive effects of chlorine, hydrogen sulfide, and other chemicals commonly found in water and wastewater. It also helps to reduce the buildup of sediment and biofilm that can lead to reduced flow and increased maintenance costs.
