Heated Hose Length Considerations
To calculate the proper length of a heated hose assembly, you need to:
- Verify that the installation is properly designed
- Do not torque the hose
- Do not overbend the hose
- Do not compress the hose
|JIC/SAE-type fittings are measured from the seat of the fitting.|
|Elbows and other fittings with a radius are measured from the centerline of the fitting|
|Flanges are measured from the flange face or from the face of the stub end if one is used|
|Threaded fittings are measured to the end of the fitting|
For assistance in making any calculation or for dimensional information on fittings, please contact our sales department.
For the following formulas:
L = Live length of hose (inches)
T = Travel (inches)
S = Hose outside diameter (see product data pages)
Verify that the installed radius is greater than the stated Minimum Bend Radius for the hose at the required working pressure.
Verify that the centerline of the hose remains in the same plane during cycling to prevent twisting the assembly.
