    Pull-off force: hose, pipe, clamp

    This is so incredibly out of line it’s ridiculous. I’m not “resorting” to anything. I’m thinking about this because I enjoy it, not because I can’t get my work done.

    Pull-off force: hose, pipe, clamp

    It’s similar but different. This is a study focused on the torque of the clamp. The other was for clamp position. This assembly also has no groove unlike the other example and is a plastic pipe, instead of a steel pipe. I am being careful not to provide proprietary information while still...

    Pull-off force: hose, pipe, clamp

    Was surprised by a study recently where we tested 6 samples for pull-off force at a 10% reduction in clamp Torque and noticed negligible shift in results. Is it possible that at higher torque the clamp is deforming the pipe, reducing the surface contact (friction) between the hose and pipe? The...

    Joint physics - hose/pipe connection

    Thank you, this was great. It completes what I was missing…

    Joint physics - hose/pipe connection

    Thank you for the welcome and explanation. Still don’t fully understand why the center location—clamp directly over the bead had the worst results. Thinking this is due to the force of the clamp being exerted unevenly (less surface area) over the hose and therefore resulting in less contact...

    Joint physics - hose/pipe connection

    Hello, Did a simple study at work recently and was confounded by the results. Hoping for a simple explanation…. Consider a pipe is inserted into a hose and a clamp is tightened over the connection. The pipe has a groove and the hose has a bead. To complete the connection the hose bead is...
