Abstract

PURPOSE: To enhance the productivity of heat-insulated exhaust pipes by interposing a metal sheet having multiple voids such as, for example, punched metal sheet, between the inner and outer cylinders of the exhaust pipe.
CONSTITUTION: The outer periphery of an inner cylinder 1 made of a long and narrow steel strip which is sealingly jointed along the rounding generatix, is wrapped with a metal sheet 2 such as, for example, a punched metal sheet, then is further surrounded by an outer cylinder 3 made of a steel strip which is sealingly jointed along the rounding generatix, and is finally welded at its one end to a flange 4, thereby to obtain a heat insulated exhaust pipe 5. Since the insulated material disposed between the outer and inner cylinders 1, 3 of the exhaust pipe 5 is made of such a multi-void type sheet metal as, for example, punched metal sheet, instead of conventionally used glass wool, the mixing of melted non-metal material into the welding portion is prevented upon the welding of the flange 4, thereby to enhance the productivity of heat insulated exhaust pipe.
