Description
Cast iron CHS17 used: for the manufacture of parts with high corrosion resistance in concentrated acids, alkaline solutions, salts (except hydrofluoric and fluoride) at temperatures up to 200 °C (the simple configuration details of centrifugal and reciprocating pumps, compressors and valves, pipes and fittings to valves, heat exchangers and other items of chemical equipment).
Note
Siliceous high-alloy corrosion-resistant cast iron in liquid medium. It is not allowed to sharply variable and shock loads and temperature changes.
