I am seeking support for a quench line gasket for 3 inch TCV, following are the information and looking for suitable gasket for this application.

The 6 inch quench line is having TCV which is SS material (A182 F321 Flange) and the line is CS material, at present the insulation gasket kit is used (data sheet attached) but no spare available. I am in need of replacement urgently, So please help to know replacement type of this gasket like low carbone, or others as alternate suitable material for this application.

Service: Hydrogen
Design Temperature of the Reactor: 430 deg. C
Design Pressure of the Reactor: 80.5 barg

Quench line Design Temp.: 365 deg. C (up to NRV)

May be you can recommend low carbon steel or soft iron gaskets for this hydro carbon service. Appreciate if you could respond on an urgent basis.
