Query on Pipe Supports
Query on Pipe Supports
(OP)
Good Day everyone!
Its my first time to post here, im hoping i would receive replies on my query and future queries as well.
Im a piping design engineer with no site/field experience thats why my knowledge is limited. Ill start my question with regards to proper selection of pipe support involving weld shoe/clamp shoe and U-bolt.
My question is what are the categories on proper selection?
Basically i know that weld shoes are used to support insulated pipelines of course provided that the pipe material allows welding. But with regards to cutting of insulation on point of support, clamp and U-bolt can be used right? But the use of clamp depends on the piping movement, clamp shoe cannot be anchored. U-bolt on the other hand has limited application due to temperature.
Say i have 1.5inch steam line with design temp of 400deg. C, project specs says that cutting of insulation on point of support for small bore lines is allowed. The piping is just resting but pipe span would require guide.
My design would be to use weld shoe and hold down guide on point of support for guide span. But the thing is for a small bore like that, im thinking if it is economical to use weld shoe.
Please do help me guys! some inputs and thourough explanation on proper support selection would really help!
Thanks!

RE: Query on Pipe Supports
Until you have grey hair or no hair, the burden of proof you must satisfy is so great that owners and engineers will both prefer to "waste" tens of thousands of dollars on proven existing solutions then use an innovative but unproven idea. Even if that support is used in similar situations but in a different industry, it will not be welcomed in your industry.
Spring supports were to be avoided at all costs when I worked in one industry, but every other support was a hanger in the other.
Hangers were the de facto support in one and avoided in favor of shoes on the other.
No amount of logic, cost savings, time savings, etc etc, was going to change the minds of the owners in those plants.
