An apparatus to enable the flow of high speed gases through the apparatus, the apparatus including modifying a metal hose which can be a metal hose or a corrugated metal hose having an exterior braid and an interior liner. The improvement includes inserting a non-bendable flange insert into a leading edge of the metal pipe and combining that with a pipe having a tapered interior wall which is welded to the metal hose to facilitate the flow of gases to a level of Mach 1 without damaging the interior portions of the interior liner.

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; andf. 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. 2. 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 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 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 and the non-bendable 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 flanged insert; ande. 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 flanged insert;f. 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 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. 3. The apparatus in accordance with claim 2, further comprising: the non-bendable flanged insert is made of stainless steel. 4. The apparatus in accordance with claim 2, further comprising: the non-bendable flanged insert and the lead-in pipe are made in two separate pieces. 5. 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 flanged insert which is retained in the corrugated metal hose at a leading edge of the corrugated metal hose;c. the braid, the corrugated metal hose, the interior liner of the corrugated metal hose and the 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 flanged insert; ande. the interior edge of the lead-in pipe welded to the respective leading edge of the braid, the corrugated metal pipe, the interior liner and the flanged insert;f. whereby, the interior edge of the lead-in pipe being concurrently welded to the leading edge of the braid, the corrugated metal hose, the liner and the 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 corrugated apparatus. 6.
