Stress related technical and execution problems in the design of process plant piping are complex and must be addressed properly. There will be some Piping Designers, Stress Engineers and others who read this and say that they agree.Others may say that they do not agree. Others will just not know one way or the other. This…
Article courtesy of Piping Technology & Products, www.pipingtech.com Introduction: PT&P produces various kinds of snubbers. Why snubbers are used and how they function are briefly discussed here. What are they? Snubbers are restraining devices used to control the movement of pipe and equipment during abnormal dynamic conditions such as earthquakes, traveling shock waves caused by…
Paulin Calls for Field Confirmation of Piping Analysis By William G. Beazley, PhD, PE Industry expert Tony Paulin, President, Paulin Research Group, called for field confirmation of pipe stress deflections and fatigue indications predicted by commonly available analysis software. Paulin said, “Checking piping displacements throughout the plant life cycle can be easily done using inexpensive…

The term “Pipe Stress Engineer” as used in this document refers to that person responsible for insuring that the pipe routing done by the piping layout designer is consistent with the allowables in the applicable piping Code. This includes; the thermal forces and the live and dead loads the piping system imposes on equipment, equipment…
Contemporary commercial piping analysis programs deal differently with the problem of apparent lift-off of an operating pipe at a rod hanger or a one-way vertical support, such as a pipe on a support rack.
