316 Stainless Steel Table D
Backing Rings
HDPE/PE100 performs exceptionally in corrosive applications, so 316 stainless steel – also known as marine grade stainless – is a perfect match. 316 has much stronger corrosion resistance to salty and acidic environments than 304, for this reason we manufacture from 316.
If the environment requires a higher grade we can manufacture from duplex or super duplex stainless, and can coat the flanges in an additional anti-corrosive coating.
