Inquiry (采购产品): back up rings We have a manufacturer of SS 316L hot water tanks looking to try back up rings as a means of avoiding premature tank failure due to corrosion caused by poor bead integrity on the inside of the tank. Tanks vary in diameter from 18 " to 24 " made of 14 ga SS. Can you advise cost and availablity of this item.
