The use of the inserts will lead to increase in the pressure drop that maybe treated as disadvantage of using inserts in some heat exchangers. However, in this case pressure drop is quite favor phenomenon as pressure should be reduced in city gas transfer line. The type of the given insert is spiral, and is made of seamless steel in accordance with the gas pipe production standard. The inserts are embedded in eight coil paths in the heater of Mavian pressure reducing station of in Kamyaran city of Kurdistan Province with capacity of 2500 m3/h. Heat transfer enhancement up to 47% obtained, which is quite important from energy saving and environmental pollution control point of view.
