Cast iron compound tubes

Ekströms Värmetekniska AB has delivered Cast iron finned tubes since the 1940th. The finned casted sleeves are integrated with a plain steel tube of pressure vessel quality. This type is well adapted to tougher conditions such as lower temperatures and higher contents of sulphur. The rhombic form on the tube body gives a low pressure drop on the flue gas side and prevents dust build ups on the backside.
