Restoring High Energy Piping System Performance by Reducing Friction

“When You’re Stuck, You’re Stuck” Over years of normal operation – like cycling and wear and tear – High Energy Pipe support friction can increase causing distress in these critical systems. Friction is a common phenomenon which is widely understood and considered in both piping analysis and support design.  Generally, a piping analyst models a […]

Fluid Catalytic Cracking (FCC) Transfer Line Flexibility – Analysis and Design Considerations

FCC’s are complex units – and the design of their transfer lines has some unique considerations. While many of the lines are refractory lined to permit construction with carbon steel piping, some sections are hot walled, at temperatures well into the creep range, for the purpose of balancing thermal expansion or, in the case of piping […]

Capacity Reduction of a Compression Member with an Initial Deformation

A recent review of equipment installed in a power plant found a piping strut that was visibly bent. Would the bend in the strut reduce its load bearing capacity as a compression member? The answer is YES!  The load bearing capacity of a bent strut against buckling is reduced. The reduction in buckling capacity is […]
