Internal Protection System - Cement Mortar Lining
Normally, all pipes are supplied with centrifugally applied internal Cement Mortar Lining.
Advantages of Cement Mortar Lining (CML)
- Centrifugally applied CML provides higher Hazen William’s C value of 140 minimum
- Reduces frictional head loss and pumping cost
- CML passivates the pipe wall against corrosion by the alkaline reaction of cement
- It prevents pitting and tuberculation of pipes and stops the production of red water
- Helps to maintain same flow area and co-efficient of friction over a long period of time
Seal Coat on Cement Lining
When specified, the Cement Mortar Lining is given a Seal Coat of Synthetic Resin as per ISO 16132.
