Suitable for electric stainless steel ball valve body parts working temperature is introduced

Suitable for electric stainless steel ball valve body parts working temperature is introduced. 1, the high temperature. The high temperature refers to the working temperature at 325 - electric stainless steel ball valve Area of 425 ℃. 2, high temperature type. In the case of an electric stainless steel ball valve working temperature is 425 - 550 ℃. 3, high temperature category. Refers to the working temperature is 550 - 650℃。 It is mainly used in oil refinery heavy oil catalytic cracking unit, it contains three rotating nozzle used in the lining of parts such as high temperature anti-wear gate valves. 4, high temperature. Working temperature is 650 - 730℃。 Mainly used on large heavy oil catalytic cracking unit in the refinery. 5, high temperature four classes. Working temperature is 730 - 816℃。 The operating temperature limit at 816 ℃ because its design is chosen standard ASMEB16. 34 pressure offer high temperature of 816 ℃ temperature. In addition, the working temperature is greater than 816 ℃, the steel is close to enter the forging temperature region, the metal in the plastic deformation range, metal plasticity is good, it's hard to work under high pressure and impact force and deformation. 6, high temperature. Working temperature greater than 816 ℃ or more. http://www。 dazkfy。 com
