Sanitary weld equipment

[HotKarl420]

hi all im looking of some resources to purchase or make a few of my own sanitary welding purge plugs as well as clamping fixtures for 316L SS tube in various sizes from 1"-8".

if anyone can help this would be greatly appreciated!!!
PS this ASTM A380-13 requirment??? is this something that the material has already undergone or will i need to do this before i weld??? I know that i am required to pickle my welds after welding as to remove any discolouration but is it necessary to have the parts immersed for 6HRS????

I've made all of my own purge stuff or back shielding doohickies. I posted a picture somewhere on this forum a while back of one of my most recent ones. I haven't the slightest idea how to find it though.
