3 需求情況

高壓加氫裝置中的閥門,既有臨氫條件,又有非臨氫條件,既有高壓條件,又有非高壓條件。本文僅討論高壓臨氫條件下應用的閥門,這類閥門雖然數量不多,但其價格卻占有較大的比例。此類閥門有閘閥、截止閥、止回閥、球閻和旋塞閥,壓力等級為 ASME 的 CL900~2500,溫度為常溫至 400℃,主體材料有 ASTMA105、A182—F11/F22/F321、A216—WCB、A217—WC6/WC9、A351—CF8C,閥門直徑為 DN15-400 mm。這些閥門的功能與普通閥門相同,但國內目前尚不具備成套供應的能力,主要原因在于閥門制造廠與用戶(尤其是工程設計部門)溝通聯系不夠,不了解閥門的使用條件和要求,缺少一套與介質條件相適應的技術文件、模具和圖紙等,而且缺步工業化批量生產的經驗。
