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.



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.
