Time：2004/7

Model：AD9M  DN 250

Nominal Pressure：4.0 M Pa

Pressure Drop：1.2 M Pa

Temperature：Crude oil with heat tracing

      Medium：Expansion and transformation of high-sulfur crude oil refinery. Due to the decrease in the supply of domestic crude oil, a middle-east crude oil transportation line from Tianjin to Yanshan Petrochemical will be built. Because the imported crude oil has higher sulfur content and more serious corrosion to the unit, it will be refined after mixing with domestic oil. According to the mixing ratio required by the refinery, the valve  adjusts the crude oil flow, the working pressure is 2.2mpa. Stable and reliable adjustment!
