Stainless pipe and not tube for student project
Does anyone have an offcut of stainless pipe available for sale?
Between 3" and 4" diameter 5-6mm wall thickness and around 12" long.
Needed for a student project in measuiring plasma electron volts we need to construct a small vacuume chamber extension to get a probe in to measuring
plasma temperature.
It needs to be reasonably nonmagnetic - hence the stainless steel and it has to meet the uni "general criteria" hence the ridiculous wall
thickness. I tried explaining that no matter how good a vacv it would never be more than 15psi but " this is the way we always do it" is
the reply. 
So it has to be pipe and not tube like exhaust pipes are made of. ( there is actually a standard defining when a tube becomes a pipe!)
We have good workshop facilities but no cash and having scrounged the uni high and low can't find pipe this size.
Help would be much appreciated.
Cheers!
You'd be surprised how quickly the sales people at B&Q try and assist you after ignoring you for the past 15 minutes when you try and start a

Not sure where you are in Scotland - Would it not be worth trying to make a connection with one of the offshore engineering companies who would use
heavy walled pipes like that.

Try local steel stock holders for an off cut- prob cost same as postage on a bit even if someone has a bit knocking about, you could even ask if they
know anyone who uses stuff like that regularly, failing that phone round engineering firms and see what they have got
