Re: Spiral seam welded pipes

However, its low cost and use in tamer services are a good combination. Seamless pipe for cooling water is definitely an overkill in comparison to spiral wound pipe.

I would strongly recommend against its use at high temperature 600F and up the welded seam presents a real hazard especially if you try to go into the creep range T>~800F. (Ref B31.3 2004)

So as you design & build your uranium extraction plant(s) you may want to keep
this in mind.

you think about the advantages and disadvantages of this kind of pipe in comparison with other welded type pipes regardless of joint efficiency and cost.Have you had any experience of utilizing this kind of pipe for any process service?
