Flame Arrestors

CIE manufactures a wide range of Flame Arrestors to use in chemical, petrochemical, and allied industries and refineries. Flame arrestors are normally installed on the end of the line or above the vessels were hazardous gases are normally vented out. They are used to prevent flames from an external fire entering into the tank or inside the pipe line. The body is normally made of cast steel cast iron, stainless steel or aluminium as per the process requirement. The internal crimped element or flame bank is made of metal sheets and gauges or corrugated sheets made of stainless steel/aluminium. The gas is allowed to pass along with the element which prevents flames from entering into the process in the event of external fire. Sizing and designing, etc, can be done with reference to API-2000 and the flame bank is so designed that the pressure drop is negligible. Sizes range from 1/2"(15 NB) to 2"(50 NB) in screwed connection and 1"(25 NB) to 12"(300 NB) in flanged connection. Flame arrestors can be used along with breather valves.
