金屬拉西環(huán)填料

金屬拉西環(huán)是最早開(kāi)發(fā)的一種散堆填料。形狀簡(jiǎn)單，它是高與直徑相等的圓環(huán)。大尺寸的拉西環(huán)（100mm以上）一般采用整砌方式規則填充，75mm以下的拉西環(huán)多采用亂堆方式裝填。

產(chǎn)品特點(diǎn)

拉西環(huán)是在1914年被F.Rasching開(kāi)發(fā)出來(lái)的。它是最早被發(fā)明出來(lái)的一種具有固定幾何形狀的散堆填料。它的外形簡(jiǎn)單，高度與直徑的尺寸相等。大尺寸的拉西環(huán)（100MM以上）一般采用整砌方式規則填充，而75MM尺寸以下的拉西環(huán)一般采用亂堆方式裝填。金屬拉西環(huán)被廣泛應用于很多領(lǐng)域，但是它的應用得最主要的領(lǐng)域是作為催化劑支撐。
　　金屬拉西環(huán)的材質(zhì)可有多種，如碳鋼，不銹鋼304、304L、410、316、316L等，可供選擇。
