Abstract
A system and an apparatus for a new design for an insulation gasket with RTJ seal for RTJ flanges in high-pressure piping are disclosed. The system includes a first pipe and a second pipe, configured to be sealed together; and an apparatus, comprising: a ring type joint (RTJ) flange, and a insulation gasket with RTJ seal, wherein the insulation gasket with RTJ seal comprises a metal core, insulating sleeves, insulating washers, metallic back up washers, and a polytetrafluoroethylene (“PTFE”) seal for RTJ grooves on either of its sides, configured to create a seal between the first pipe and the second pipe.

An apparatus, comprising:
- a ring type joint (RTJ) flange, configured to connect to a pipe;
- and
- an insulation gasket with RTJ seal, configured to connect to the RTJ flange, wherein the insulation gasket with RTJ seal comprises a metal core, insulating sleeves, insulating washers, metallic back up washers, and a polytetrafluoroethylene (PTFE) seal;
- wherein the insulation gasket with RTJ seal accommodates the PTFE seal inside a groove of the RTJ flange, and
- wherein the PTFE seal extends to an edge of a diameter of the RTJ flange to prevent a metal on metal contact between the RTJ flange and a metal core of the insulation gasket with RTJ seal.
