For rest support only can clamp act as a RF pad /saddle ?
--------------------------------------------------------------
In case say 54" line with thickness 9.27 mm , if as per thumb rule R-pad is required (welded shoe with R-Pad) , and situation is that , client ask for clamp shoe in case of welded shoe to ease construction in cold Russian environment , the question is can clamp thickness act as reinforcement pad helping the pipe. Its 2 clamp shoe support.

This question is valid only for rest supports. as for axial stopper we are going with welded support only.

In rest support the concern is , can pipe maintain its circularity against loads at support if we use clamp.

In other word , at rest support , case 1 is welded support with r-pad, case 2 is clamp support ( say clamp is of same thickness of R-pad) , will both cases have same effect on pipe circumferential stresses ?
Thank you.
