Hello Richrad,

and do we should enter friction factor 0.3 (carbon steel - carbon steel) in restraints dialog box; as pipe can move in "X" or "Z" direction.

Next, what i think is that this 0.3 friction factor is sliding of CS plate to a CS plate in normal conditions. If we press the two CS plates plates by force and then try to slide; in this case we generate more friction, and so i think in this case the friction factor should not be 0.3 and it should be more.

Similar is the case of U Clamp/bolt. If U clamp is tight enough with the pipe then when pipe tries to move the frictional effect on the pipe will be more (because of U bolt which is tightly bolted with the pipe); and so 0.3 friction factor is not valid.

Am i right?

If so how to cater this increased frictional force on pipe in stress analysis.

Thanks
