Knife-Edge 70-Degree Chamfer Profile
The circular knife-edge bites into both sides of the 2-mm copper gasket, forcing metal into plastic flow under immense bolt torque.
Radial Capture Groove to Restrain Lateral Creep
The flange well restrains the copper ring from squeezing outward, maintaining airtight metal-to-metal seal integrity through thermal cycles.
Surviving 450°C Ultra-High Vacuum Bake-Out Cycles
Because thermal expansion coefficients of 304L stainless steel and copper closely match, joints remain helium leak-tight upon cool-down.
⚠️ Technical & Safety Verification
The empirical methods outlined in this study reflect verified ultra-high vacuum (uhv) physics & molecular flow metrology protocols and field measurements. Always verify safety standards and consult accredited specialists before executing structural or high-energy physical tests.
