I want to know what is the difference between using a line stop and a v-stop in a vertical pipe?
If a v-stop is used with gaps 0mm, does it mean same as line stop with gap 0mm?
In which condition of vertical pipe should we use line stop or v-stop?
I understand that when we use line stop, no friction is involved
But in v-stop, friction is involved only after gap closes or does it involve before the gap closure?
If a pipe includes a pipe shoe, does this mean we must include a v-stop with friction?
Thank you in advance.

On a vertical run of pipe, a rigid V-stop is the same as a rigid line stop. See AutoPIPE help on support overview to completely understand a support bearing direction.
As you know (imaged above), friction is available on V-stop support but is not available on the Line stop support. With a V-stop, a friction force will be applied so long as the pipe is in contact with the support for a given load case. Otherwise, if the pipe is not in contact with a V-stop support there is no friction force applied.
Question: If a pipe includes a pipe shoe, does this mean we must include a v-stop with friction?
Answer: A pipe shoe rigidly connected to a pipe that is resting atop a V-stop, Then suggest modeling a V-stop support with the correct gap restrictions and anticipated friction caused the shoe rubbing on the support (ex. steel on steel, steel on rubber, or other).
