UG analysis fail EXP case

Cooling water UG line 80 inch , stress EXP fail at many intersection and branch 8 inch UG line.

- Possible to add ANC at those intersections/ branch?
- Any solution to solve stress in EXP case without change routing.?
- ANC Support is anchor block or thirst block ? How different?

please help.

A thrust block sits to one side of the pipe to inhibit movement of the pipe into that direction, but may permit movement in one or more other directions (as permitted by the soil). Generally made of concrete.

A pipe anchor, generally made of concrete, encases the pipe to inhibit movement in all directions. May need a metallic attachment to prevent sliding through the block.

At 80" diameter, however, where are you on the D/t ratio?

Pipe THK 12.7 mm

D/t = 160

Generally we tend to avoid using beam-modeling software like CAESAR for D/t ratios greater than 100, as the failure mechanisms often consist of thin wall buckling.

If your cooling water line is feeding equipment, you run the risk of feeding mud to them due to failures CAESAR isn't design to catch.

With that said, are you sure you should be using the temperature you're using, whatever it is, for the line underground? You may wish to push back for verification on that number. It may be likely that the temperature of the line should be really close to that of the ground anyways, rendering expansion stresses trivial.
