Expanded Graphite Packing

Expanded graphite packing: Expanded graphite packing is weaved with YL-1272 expanded graphite yarn featuring high temperature resistance, chemical corrosion resistance and outstanding sealing properties. It is often used in steam valves of power stations and a variety of static sealing positions with high temperature, high pressure and strong chemical corrosion (except a small number of strong oxidant like concentrated sulfuric acid). Scope of application: The maximum operating temperature: 850 °C (non-oxidizing atmosphere) 450 °C (oxidizing atmosphere) The maximum operating pressure: 25.0MPa PH value: 0 - 14
