характеристики герметизации клапана в низкотемпературных условиях
герметичностьindustrial valveTypes of Valve Sealing Performance To address this issue, low-temperature valve designs typically avoid using traditional non-metallic sealing materials, especially in environments where temperatures fall below -70°C. Non-metallic materials can be combined with metals through special processes to form composite structures to improve low-temperature sealing performance. However, some non-metallic materials still perform well at low temperatures. For example, polyethylene...
