Dear J. Montero,

Last time, I have involved the same like this. The force will be very big because we stop the displacement of pipe using anchor due to temperature change.
I calculated the force using two ways. First using manual calculation based on Pipe stress analysis book (Sam Kannappan) and second I use Caesar to modeling the underground pipe. And then, I use the anchor flange (inside of concrete block) to hold the force (ASME sec. VIII div1 appendiks 2). Concrete block calculation by civil.
If it is possible, We might be release the pipe to move. I mean if the location of equipment to be protected from displacement is far from the anchor block. Let the pipe moving so the force will go and no need to provide anchor block. We can check the value of displacement at equipment using caesar.
Please correct it, If I'm wrong. Sorry.

Thanks
Regards
Arief

Dear J Montero,

Please refer NFPA - Rules for laying pipes and Appendix A thereto which treats your subject fairly well. I hope this will be of use to you. Regards,

Hapy New Year 2005 for al!!

Some of you, could indicate where to obtain information to me on blocks of anchorage for pipe lines. I am making a flexibility study to determine the forces in the anchorages in the points where the pipe leaves the ground, and they are to me force very great. It would be thankful if somebody says to me where I can obtain information on the matter. again thanks.
