Help - Need to find a pipe supplier!
(OP)
I need to find a pipe supplier to get a piece of SA 106 GR B pipe to machine down to 8.250 ID x 9.250 OD x .500 nom. thk.
I currently have taken a piece of 8" sch 80 (.500 nom.)and expanded it to 8.250 ID. I am having it magnaflux tested to check for cracks. After expanding, the material thickness thinned down to .450 thk.. I figure the percentage of expanding is 7.145%.
The customer also states SA 106 GR B as "tubing". I my book SA 106 GR B is seamless pipe. They stated their previous vessel supplier is using it why can't you. I asked for them to supply me with the supplier info but they can't do that.
This is being used as a shell section in a pressure vessel. Any comments or help would be greatly appreciated.
Thanks,
Ben

Although not as common as pipe, you can buy mechanical tubing in some odd sizes. I don't know that any of it meets A106 spec, necessarily.

Shows a 9.25" OD x 8.25" ID x 1/2" wall mechanical tubing as a stock item.

We have used 1/2" rolled and welded shell in previous design's but I was trying to exhaust all avenues to take cost out of fabricating and machining. I was also trying to do the "If they can do it, then I can do it" scenario.
Thanks to everyone for their response,

From an AI's standpoint I would concur with JStephen's post. Such an approach would save you a lot of headaches ( and money ), if feasible.
