進口低溫閥門是指采用不銹鋼材質(zhì)，經(jīng)過低溫深冷處理，帶加長桿，適用于適用于介質(zhì)溫度-40℃～ -196℃的閥門。低溫閥門包括低溫球閥、低溫閘閥、低溫截止閥、低溫安全閥、低溫止回閥，低溫蝶閥，低溫針閥，低溫節(jié)流閥，低溫減壓閥等，主要用于乙烯，液化天然氣裝置，天然氣LPG LNG儲罐，接受基地及衛(wèi)星站，空分設備，石油化工尾氣分離設備，液氧、液氮、液氬、二氧化碳低溫貯槽及槽車、變壓吸附制氧等裝置上。輸出的液態(tài)低溫介質(zhì)如乙烯、液氧、液氫、液化天然氣、液化石油產(chǎn)品等，不但易燃易爆，而且在升溫時要氣化，氣化時，體積膨脹數(shù)百倍。
