Description
Cast iron CHS17M3 used: for the manufacture of parts with very high corrosion resistance in sulphuric, nitric, hydrochloric acids of different concentration and temperature, aqueous solutions of alkalis and salts at the local temperature drop to 30 °C in the absence of dynamic and variable and pulsating loads (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.
