Metal HoseTechnical Data Minimum Live LengthDetermine the centerline bend radius required for yourapplication. Under the column headed "Centerline bendradius in inches", find your radius and read horizontallyto the desired degree of bend (45 o , 90 o or 180 o ).The number in that column will be the minimum livelength required to make that degree of bend along thedesired centerline radius.Note: Add fitting length dimension "A" plus the minimumlive length to calculate OAL.Centerline Minimum Live Length in inchesbend radiusin inches 45 o 90 o 180 o1 1 2 42 2 3-1/2 73 2-1/2 5 104 3-1/2 6-1/2 135 4 8 166 5 10 207 5-1/2 11 228 6-1/2 13 269 7-1/2 14-1/2 2910 8 16 3211 9 18 3612 10 19-1/2 3913 10-1/2 21 4214 11-1/2 22-1/2 4515 12 24 4816 13 26 5217 13-1/2 27 5418 14-1/2 29 5819 15-1/2 30-1/2 6120 16 32 6421 17 33-1/2 6722 17-1/2 35 7023 18-1/2 36-1/2 7324 19 38 7625 20 40 80Centerline Minimum Live Length in inchesbend radiusin inches 45 o 90 o 180 o26 21 42 8327 21-1/2 43 8628 22-1/2 44-1/2 8929 23 46 9230 24 48 9531 24-1/2 49 9832 25-1/2 51 10134 27 54 10836 28-1/2 57 11438 30 60 12040 32 63 12645 36 72 14450 40 80 16055 45 90 18060 49 97 19465 53 105 21070 56 112 22480 65 130 26090 73 145 290100 80 160 320120 95 190 380140 112 225 450160 128 255 510180 143 285 570200 160 320 64014
Metal HoseTechnical DataThorburn flexible metal hose assemblies are manufacturedto the highest quality levels to assure maximumservice life. The following precautions shouldbe adhered to when installing a flexible metal hoseassembly.CORRECTTRAVELINCORRECTTRAVELAvoid Improper HandlingThorburn metal hose can be damaged by draggingor when subjected to external abrasive or corrosiveconditions. Avoid installing hose in areas where itmay be subjected to corrosive sprays, spills, etc.CORRECTINCORRECTTRAVELRIGHTSUPPORTTRAVELDROOPINGWRONGTRAVELTRAVELTRAVELRIGHTWRONGMOTIONMOTIONTRAVELTRAVELRIGHTTRAVELWRONGTRAVELAvoid OverbendingOverbending Thorburn metal hose can result in prematurefailure. This often occurs at the end connections and maybe avoided by installing an elbow or interlock guard.Avoid TorqueTorquing or twisting Thorburn metal hose reduces servicelife substantially. When installing metal hose, it is importantthat all movement originates in the same plane as the centerline. Another precaution against torque is the use of a floatingflange or union on one end of the assembly.Calculations for minimum live length excluding end fittingsThorburn flexible metallic hose assemblies are usuallyflexed in accordance with one or a combination of themodes of motion shown below. To obtain maximumreliability it is essential to calculate the length of anassembly that will not be flexed beyond the minimumbend radius. The following formulae give a guide indetermining the lenght of tube required. They are basedon standard applications using our current prodluct range.Variations should be discussed with our technical dept.L = Minimum Live Length excluding end fittingR = Minimum Bend RadiusM = Movement π= 3.142VERTICAL LOOP –VERTICAL TRAVELL =π (R+M) ( )L = π R+ M 2C = π M +R4VERTICAL LOOP —HORIZONTAL TRAVELOFFSET OR LATERAL MOVEMENT(ONLY SUITABLE FOR SMALLMOVEMENTS OR STATICINSTALLATIONS)L = √20 x R x M15
