Arief:
Agree with you in general - good point on the temperature expansion, but for all - don't forget pressure expansion. I saw a case where an axial inlet centrifugal compressor was installed, with the suction line almost a straight shot for about 500 ft to the first anchor. Everything was bolted in place with pipe at zero psi, then pressurized up to 1200 psi for test. Moved the compressor about 1/4 inch. End comment - if you have serious pressure swings, you need to examine effect.

   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,

   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.
