Internal protective cement lining for steel pipes and fittings

The technological process of internal cement lining assures anti- corrosion protection and stability of hydraulic parameters of pipe- lines for water and sewages and allows manufacturing products that meet all the requirements demanded by customers and inter- national standards.

Applications:
Steel pipes and fittings with cement lining are used for raw and potable water supply pipelines as well as for sewage system for both municipal and industrial effluents. These pipe systems assure cost effective and ecological solutions, due to material and energy saving in terms of extension of their working life and environmen- tally friendly technology.
Advantages of cement lined steel pipes and fittings:

• resistance to corrosion also in case of aggressive waters by appliation of sulphate resistant cement assures operational lifetime of product for several decades,
• full resistance to various oxidizing agents, e.g. ozone, chlorine,
• no tendency to incrustation which improves operational character of the pipeline,
• very high abrasion resistance allows high flow rate of fluids,
• full resistance of cement lining to plastic of strain of the steel pipes,
• chemical composition of the lining i.e. cement and silica sand as natural raw materials ensure that in contact with water the lining does not have any negative influence on human health.

Technical data:
We make cement mortar lining for steel pipes of diameters from 159 mm to 2032 mm, length from 6 m to 18 m, according to the conditions specified into the following standards:

• DIN 2614,
• DIN 2880,
• PN-EN 10298.
