The convoluted joints have an inner lip and an outer lip at opposite ends of the strips; and the carcass further comprises a plurality of channels formed along an entire length of first and second sides of the strips, the channels creating at least one fluid passage in each of the convoluted joint forming the carcass for the passage of fluids between the inner and outer diameters.04-07-2016

20080216911Integrated spiral duct - Provided is an integrated spiral duct including: a curved duct; and straight connection ducts formed at both ends of the curved duct, wherein the curved duct is integrally formed with the straight connection ducts in spiral type without any joint. Therefore, since a metal strip is continuously wound to form a duct without any joint, it is possible to reduce the number of manufacturing processes to remarkably increase productivity, quality, and durability.09-11-2008
20080245435STRETCHABLE METAL TUBE - A tube is made of profiled metal strip which includes an end leg extending in parallel relationship to a tube axis, an inner leg extending in parallel relationship to the tube axis at a first distance, and an outer leg extending in parallel relationship to the tube axis at a second distance which is greater than the first distance. The inner leg is connected with the outer leg by a transition. A double-folded loop hook extends radially for connecting the end leg with one member from the group consisting of the inner leg and the outer leg, and an end hook extends radially and is connected to the other member of this group.10-09-2008
