slug flow VS slug damper device

slug flow VS slug damper device

slug flow VS slug damper device

(OP)
Hi,

A 4'' nom. dia. piping has high propability of slug flow and the current support shall be redesigned.  I was thinking to put a fix support or a hydraulic shock absorber damper device at the end of a long horizontal section.  

Normally, when you design pressure piping (ASME B31.3) including a slug flow possibility, what kind of support are you using to be sure to keep the piping on the pipe rack and not overstress it when the slug flow will occur?
 

RE: slug flow VS slug damper device

A clamp or full anchor, or even an anchor flange.  However when you add restraints, you increase stresses, so then you must check allowable stress with the slug flow and the restraint in place.  If stresses are over allowables, then the only real alternative is to add wall thickness to the pipe to get those stresses below allowables.
