Issues with the MESG value of flame arresters
Thread Content
If the medium inside the pipeline connected to the flame arrester is of IIA grade, and the explosion protection rating for the area as indicated in the explosion protection zone map is IIC grade, should the MESG value of this flame arrester be determined based on IIA or IIC?
Select the model based on the properties of the gas and operating conditions. It is already known that the most hazardous component is IIA, so the flame arrester is designed with the maximum experimental safety clearance. Be careful at the steady-state pipeline position.
