Inquiry (采购产品): Helium Leaks Hi I want to build an inverted sealed sheet steel welding tank, to contain a helium atmosphere in. I have been told (by some aparently less than bright people) that the helium atom / molecule is so small that it seeps through the sheet steel plate it's self. I am more of the opinion that this is a basically dubious theory based upon ignorance and inexperience. What are your opinions upon this subject? **** Hidden Message ***** Shane Shane AUS Company: yes E-mail: human_race@iinet.net.au **** Hidden Message ***** human_race@iinet.net.au
