Hello people.

In the normal course of supporting pipework, we can use either welded or bolted shoes.

Now,as per PED, the welding of any attachment to the pipewall requires coded weldiers, so for time and money, we are switching to bolted shoes.

My question is this, what limitations do a bolted shoe have over a welded one?

I intend to use bolted shoes except where supports are required to resist forces, at which i will specify a welded shoe. (over say 3")


Thoughts please.
