Gasket Material
(OP)
Hi to All
The answer to the following question shall be greatly appreciated:
I am trying to install a SSDS (super Duplex)2500# RTJ flanged madular DB&B valve on a Flow Line using a 6"x 2"-2500# RTJ Nipoflange in A350 LF2 material (Flow line is API 5LX52N), now, What type of Gasket is the most appropriate between these two diffrent type of flanges ?, I am contemplating gaskets of type Octagonal Ring AISI 316 R26! will this be OK with regards to Corrosion?
Thanks a lot

I found out (in addition to your comments)that HARDNESS of the gasket in comparison with the 2 different type of surface material of the flanges, play a significant part when it comes to corrosion and leakage.
Thank you

Flexitallic make a flange rescue gasket in an RTJ form to fight corrosion.

Pikotech also make there VCS gaskets

There are a few others if you Google. Also due to the difference in metals across the flange ensure you get a full insulating kit for the whole joint (insulating bolt sleeves + washers), this will prevent galvanic corrosion.
Disclaimer:- I work for Flexitallic, but I am not a salesperson so am not promoting anything just trying to help.
