Hi,

Will somebody please explain to me the question below?

There are many types of supports even most of companies having there own standards for piping support.

If there are two possibility of supporting the insulated pipeline, means one is by directly welding the half cut I-beam and another is half cut I-beam with clamp, then which one is the standard practice?
What parameter should be considered while using above mentioned two supports?

Your question is "which is standard practice, Weld on Shoe or Clamp on Shoe.

The answer is, Both depending on the pipe you are attaching it to.

Example:
The Weld-on-Shoe would normally be standard when attaching to a standard Carbon Steel pipe.

The Clamp-on-Shoe would normally be standard when attaching to certain Alloy pipes or to a Lined Carbon Steel pipe.

Some companies only use Clamp-on-Shoes for all applications.

Pros and Cons (Good and Bad) of Shoe types:
Bad: If you have Alloy pipe lines and you want Weld-on-Shoes then you need to make the Shoe of the same alloy as the pipe.
Good: Clamp-on-Shoes can be attached to any type of pipe
Bad: Clamp-on-Shoe can shift under some conditions resulting in damage to the pipe
Good: Both Weld-on-Shoes and Clamp-on-Shoes are commercially available pre-made
Do it once and Do it Right

The reason to choose clamped shoe or directly welded shoes mostly depends on the client's preference. In my last few project's experience this has been mostly governed by the client's preference.

As per my opinion In the plant like Power/Refineries where there are heavy forces acting on because of the temp/pressure conditions of the pipes preference to shoes directly welded to pipes for more secured pipe supporting & whereever there are not much forces acting because of no critical temp/pressure conditions clamped shoes are preferable.

I even seen & worked pipe supports (frames) clamped to the main steel...that too because of the client's requirement. Not even bolting is allowed on there..!

I request again for the very much experienced pipers like Jop to guide us on the above matter & the reason of preference for the choice of pipe support types SHOEs or the frame connections.
