Hose Clamp + Friction Force
Hose Clamp + Friction Force
(OP)
Hi All :
How do we find the axial load a pipe a take before it slips from the Hose Clamps at the expansion joint ?
I have two aluminium pipes wrapped around by Ventglas Sheet( Forming an expansion Joint). The Ventglas sheet is clamped to the aluminium pipe using 4 hose clamps, two on each side. The specification of the clamp is as follows :
Torque : 35 in-lbs.
Band Width : 9/16"
Band Thickness : 0.022"
SAE No. 188.
Now, I need to figue out the maximum axial load the pipe can take before the clamp slips out from the pipe. What approach is to be taken to the same.
Thanks

RE: Hose Clamp + Friction Force
Yeah, you could probably make a stab at calculating it...but there are a lot of variables, the biggest being the friction factor between your rubber and the aluminum pipe. You'd have to test to measure this, so why not just do one test and group all the variables into one nice, neat data point.
