席型(xing)網(wang)濾(lv)網(wang)也叫不銹鋼密紋網(wang)，在長江的以南地區或國外也稱為菏(he)蘭布。它是采用(yong)(yong)優質(zhi)不銹鋼絲(si)編(bian)織而成。主(zhu)要特點是經向(xiang)、緯向(xiang)絲(si)徑和密度有較(jiao)大反差(cha)，因而網(wang)子厚度和過濾(lv)精度及使用(yong)(yong)壽命比方孔網(wang)有較(jiao)明顯的提高(gao)，不銹鋼席型(xing)網(wang)的過濾(lv)精度是方孔網(wang)布無法實現(xian)的。

席(xi)型網過濾網常用(yong)材(cai)質：SUS302，304，304L，316，316L、純(chun)鎳絲等。
