Claim Text:
1. An apparatus to enable a flow of high speed gases through the apparatus, the apparatus comprising: a. a corrugated metal hose covered by a braid, which corrugated metal hose in turn covers an interior liner of the corrugated metal hose; b. a non-bendable stainless steel flanged insert which is retained in the corrugated metal hose at a leading edge of the corrugated metal hose, a length of the non-bendable stainless steel flanged insert is approximately equal to an interior diameter of the corrugated metal hose; c. the braid, the corrugated metal hose, the interior liner of the corrugated metal hose flanged and the non-bendable stainless steel flanged insert each having a leading edge; d. a lead-in pipe having a straight exterior sidewall and a continuously inwardly tapering interior sidewall ending in an interior edge leading to an opening at a leading edge of the non-bendable stainless steel flanged insert; e. the leading edge of the lead-in pipe welded to the respective leading edge of the braid, the corrugated metal hose, the interior liner and the non-bendable stainless steel flanged insert; and f. the non-bendable stainless steel flanged insert and the lead-in pipe are made in two separate pieces; g. whereby, the interior edge of the lead-in pipe being concurrently welded to the leading edges of the braid, the corrugated metal hose, the liner and the non-bendable stainless steel flanged insert prevent abrasion of the interior liner and provide a smooth laminar flow and reduce turbulence to enable the conduction of high velocity fluids and gases up to Mach 1 through the apparatus.
