In what aspect?
The first test would be a magnet. I have ran across several hundred pieces of “high-quality” stainless from China that were Ferrous. High Quality stainless should always be non-ferrous and void of any iron.
The only option besides a magnet would be visual. Checking for weld quality, porosity issues with the purging or internal welds, suck-back, fitment, all would be visual indicators towards the quality.
Feel free to post pictures if you have any questions!
Well I have a magnetic flashlight and it doesn’t stick to the steel tanks but it sticks to my column rack
ETS makes steel now?
I actually have an xray report from metallurgy or something like that for my tanks. I should find that
that checks for internal cracks etc
xrf is used to determine the elemental composition of materials
china swaps out what you buy for cheap shit like its a SOP
most pharma companies have been so burned by this practice they moved mfg to india so now the chinese mostly just have weed and brewery/kombucha/coffee people to scam with their vessels
All of ETS’ Cylinders and Tank heads are made in the states…
This is pretty awesome experimental planning, @borysses ! I’d love to confer with you over your lab notes and analytical data! I might even be interesting in a joint project, if you’re willing! Please see DM! 
Ride eternal @cyclopath …now cumm’ere and let me spraypaint your teeth! 
Phased array ultrasound and penetrant testing seem to be the standard methods of NDT for stainless nowadays
Liquid Penetrant Testing for Stainless Steel Flanges.
P/T is a good cheap way to periodically inspect stuff
Yeah man. We have 5 products going thru bioethical commity to allow usage on humans in trials focused on alternatives to opioid pain killers and another 8 going thru cell cultures trials (lung and colon cancer). Today I got quite interesting info regarding terpenes. Looks like hummulene is promoting cancer cell growth, d-limonene as well but not as much and myrcene is kiling cancer cells.
Dude! We need to TALK!
That’s really, really interesting
that is awesome!
and…
Rolly-pollies hold onto cadmium maybe…but remediation prolly isn’t their thing…
