The function of an internal lining is to provide a smooth bore to maximise flow capacity and minimise internal corrosion over the life of the pipe. In potable water applications, linings should not unduly affect the quality of the water being transported.


SINTAPIPE® has a fusion bonded polyethylene lining applied to the inside of steel pipes. SINTAPIPE is ideal for aggressive water applications such as high CO2 water, septic sewage, trade wastes and highly saline water.


It can operate at temperatures up to 50°C. SINTAPIPE makes use of the SINTAJOINT® rubber ring jointing system to provide an unbroken, end to end, coating system.

Cement Mortar Linings

Cement mortar linings provide the required standards of corrosion protection performance, at low cost, over long periods of service in potable water applications. The lining actively prevents corrosion by passivating the steel and can be expected to achieve a service life well in excess of 100 years.


Cement mortar linings are also used for wastewaters and saline waters. In these cases Steel Mains can assist designers with specifications for special cement lining and treatment to suit water chemistry and required design life. High alumina cements are often required for aggressive sewerage.


Cement lining is applied by spinning the pipe in a centrifugal process that results in a dense lining with a smooth surface. The lining is cured for a minimum of four days before the pipe is transported for installation. The dense lining produced offers good chemical resistance to potable water, saline and wastewater applications.


Cement mortar linings using General Purpose (GP), General Blend (GB), Sulfate Resistant (SR) and Calcium Aluminate (CA) are available. Reinstatement of internal field joints when the pipe is welded is a simple task, requiring minimal skill, to achieve an integrated lining.

Bitumen Seal Coat

High pH can develop in water, especially in small diameter cement mortar lined pipelines, where the water is aggressive and the flow rate is low, resulting in a long residence time. To overcome this potential problem seal coatings have been developed to restrict leaching from the cement mortar lining.


Pipes can be supplied with cement mortar lining and bitumen seal coat if required. This must be specified at time of quotation.
