Internal protective cement lining for steel pipes and fitting
The technological process of inner cement lining assures anticorrosion protection and stability of hydraulics parameters of pipelines for water and sewages and allows to manufacture products that meet all the requirements posed by customers and international standards.
Applications:
Steel pipes an fittings with cements layer 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 environmentally friendly technology.
Technical data:
We make cement mortar lining for steel pipes of diameters from 159 mm to 2020 mm, from 6 m 14 m length, according to the conditions given in DIN 2614, DIN 2880.
Advantages of cement lined steel pipes and fittings:
- Resistance to corrosion also in case of aggressive waters by application of sulfate 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 all characters 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 for human health.
