Carbon steel ball valve is suitable for non-corrosive media such as oil, steam and water. Under certain conditions, for example, certain corrosive media can also be used in a range of temperature concentrations of carbon steel.
The applicable temperature range of carbon steel is: -29 to 425°C. This is due to the carbon steels' migration and aggregation of carbon atoms in the structure at high temperatures and their conversion to graphite due to the extremely low strength of the graphite and the use of flakes. Exist in the pearlite, will greatly reduce the strength of the material, and increase the brittleness. Under normal circumstances, carbon steel has a tendency to graphitize at temperatures above 425°C for a long period of time, but it appears clearly when it exceeds 475°C. Sinopec Standard SH/T3064 {General Valve Selection for Petrochemical Steel, Inspection and Acceptance} The applicable temperature range of the expensive carbon steel valve is -20 ~ 425 °c, and the lower limit is -20 °C based on GB 150 {steel pressure vessel}. But when using WCB, WCC two kinds of steel body, valve cover, gate, (valve), bracket, the applicable temperature limit of these two kinds of steel is -29 °C.
