Abstract
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.
Claims9
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.
