Metallic Hose Assemblies - Thorburn Flex Inc

Metal HoseCorrugatedThorburn's standard annular flexible core starts its lifeas a coil of stainless steel strip which is mechanicallyformed into a tube and then longitudinally butt welded.Considerable care is taken to ensure that the strength ofthe butt weld is greater than that of the parent material.This rigid tube is then transferred to the corrugating machinewhere the corrugations are formed. After the tubehas been corrugated, it is pressure tested to ensure thatthere are no leaks.Thorburn's "Tight weave" braid design is carefully calculatedto ensure that the number of wire gauge and theangle of lay give optimum performance. After the attachmentof the end fittings, the hose is pressure tested to1-1/2 times the working or design pressure and test certificatescan be supplied if required.Why Buy Thorburn Annular formed Corrugated Metal Hose AssembliesAnnular (parallel) CorrugationsHelical (spiral) CorrugationsVSSeparate corrugations form acircle or ring in itselfSpiral path with one continuous corrugationrunning the length of the hoseThorburn's standard metal hose core is corrugated intoa close pitch annular profile. These annular corrugationspermit the hose to be bent or isolate lateral deflectionwhile remaining liquid and gas tight.Thorburn's annular corrugations permit the hose assemblyto absorb its thermal activated extension and compressionmovements.VSVSHelical corrugations tend to be less flexible and yieldhigher stress under flexural movement. In other words1) helical assembly takes more force to bend and requireslonger lengths to make a bend; 2) helical assemblylife is more adversely affected by flexure movementresulting in a shorter life.Helical corrugations have a tendency to twist whensubjected to extension and compression movement. Inother words, if your flexible hose component is subjectedto a change in temperature, the hose could failprematurally.3
