Graphite Flange for High Temperature Pipeline
Graphite flanges are used in high temperature vacuum and inert gas piping systems where metallic flanges would soften, deform, or corrode. They provide reliable sealing and structural integrity at temperatures up to 2000C.
Our graphite flanges are precision machined from high strength isostatic graphite, available in standard and custom dimensions to match your pipeline system requirements. They are widely used in vacuum furnaces, semiconductor processing equipment, and high temperature gas delivery systems.
