Use of Piping Wear Pads
Use of Piping Wear Pads
(OP)
Good morning guys,
I have another question for everyone today. Our mechanical engineer has a tendency to want to put wear pads on all our piping to avoid direct metal to metal contact with any T support beam, pipe rack beam, or structural beam.
My question is, is this a common practice based on everyone else's experience? I understand piping that may have considerable movement requiring protection from scraping the beam, but for piping that should have little to no movement, what is the point? Is this just another unnecessary added cost to a project? Is it not common practice to just rest piping on top of the steel beam?
And just to be clear, I'm only talking about bare exposed piping with no insulation. If more information is needed before answering my question, please let me know.
Thanks

You asked:
"is this a common practice based on everyone else's experience?" No, it is not common practice.
"Is this just another unnecessary added cost to a project?"
Yes it is an unnecessary added cost to a project.
Sometimes its possible to do all the right things and still get bad results

Because of the stray currents that can frequently exist in a process plant, there are some who advocate dielectric isolation of piping from support structures.
Even "cold" piping systems have very slight movements (thermal, wind etc) relative to their support structure.
Accelerated corrosion can exist.... and this can be mitigated by a combination of coated u-bolts and support pads.
A slight increased cost upfront can save corrosion mitigation costs later on

Piping Wear Pads also prevent friction damage from vibrations.
