A.W. Cook Cement Products 242 Amy Industrial Lane Hoschton, GA. 30548 Phone (706) 654-3677 Fax (706) 654-3662 DESCRIPTION Horizontal Pipe Lining Mortar is a blend of Portland cement, silica sand, polymer modified and contains corrosion inhibitors. The mortar is specifically designed to be centrifugally cast inside of existing Linings - Northwest Pipe CompanyCement mortar lining adds pipe stiffness to resist external loads and deflection. A key contribution is the passivation of the steel with the high Ph mortar to form a corrosion resistant film that protects the pipe wall. The lining has the ability to selfheal autogenously or regenerate the corrosion resistant film in the presence of water. Best

Method for lining a pipe with a cement mortar - Mainlining

What is claimed is:1. A method of lining a section of water main pipe having an interior surface comprising taking the water main section out-of-service, depositing a cement mortar on the interior surface, forming on the mortar a crust of calcium carbonate to a thickness which is less than an entire thickness of the cement mortar deposit such that mortar underlies the crust for Pipe cement mortar lining, Cement Mortar Lined Steel PipeCement mortar lining can ensure a safe and abundant water supply for your water customers for many years to come. Cement will also extend pipe life by inhibiting the corrosion of ferrous materials and preventing future rust and tube regulation build up.
