How resistant to movement are pipe clamps?

When using pipe clamps as part of an anchoring assembly, the resistance to the pipe movement can be developed in two fashions. One way would be to apply sufficient bolt torque to the pipe clamps which produces a friction load which is adequate to suppress any of the associated pipe movement. Another way would be to use lugs welded onto the pipe outer diameter which would prevent pipe movement at the clamp location.
