Heat exchanger Tubes are used in all types of process industries. Characteristic requirements are: bead worked weld,  fixed lengths and extensive testing. In order to meet the demand for rapid delivery,  we have a strip stock with both standard and special grades of steel in the most common thicknesses.

Application: For tubular heat exchangers, condensers and similar heat transfer apparatus.View more application...
