Cement Mortar Linings General Purpose (GP)

Calcium Aluminate Cement (HAC)


Bitumen Seal Coat





SINTAKOTE is a medium density polyethylene which is applied to the pipe by a fusion bonding process. Polyethylene, supplied as a powder, is fusion bonded onto a blasted preheated steel pipe. This process provides a continuous and holiday free coating, with a smooth surface, ideal for above and below ground applications even in aggressive soils and when exposed to direct UV sunlight.


SINTAKOTE was developed by Steel Mains, in conjunction with Australian Water Authorities, to overcome pipeline failures due to inadequate coating systems. A worldwide research project was undertaken by Steel Mains to find the best coating system available. Further developments have maintained SINTAKOTE as a world leading coating and lining system for steel water pipelines.



Please refer to our Design Manual for more detailed information on our Sintakote Coating system.


Features of the coating include:

  • Excellent adhesion
  • High impact and load resistance
  • Excellent chemical resistance
  • High dielectric strength
  • High electrical resistivity
  • Low water absorption
  • Resistance to soil stresses
  • Wide service temperature range temperatures from -40°C to 70°C have no detrimental effect on SINTAKOTE
  • Ability to accept cold bending of the pipe in accordance with AS 2885 without damage to the coating 


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 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.

Calcium Aluminate Cement 

Calcium Aluminate Cement (CAC) mortar lining is a solid, durable material that is used to protect the internal walls of the pipeline from deterioration. CAC has properties which protect the pipeline from aggressive fluids with extreme pH values and/or abrasive solids. CAC lining provides superior resistance to chemical attack and abrasion, preventing degeneration of pipe walls from sewage and industrial waste. It contains a rapid-hardening material which resists high temperatures and corrosive substances (monocalcium aluminate (CA)).


CAC accommodates extreme pH ranges from pH 4 to pH 12 by protecting the internal steel surface from corrosion and tuberculation when conveying aggressive fluids common in sewerage and wastewater pipeline.



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.


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.
