內(nèi)襯不銹鋼管件

內(nèi)襯不銹鋼三通

內(nèi)襯不銹鋼復(fù)合管件外層采用瑪鋼管件,內(nèi)層為不銹鋼,內(nèi)外層經(jīng)特殊專業(yè)技術(shù)一次成型。

特點(diǎn):

組成部分:內(nèi)襯不銹鋼復(fù)合溝槽管件由可鍛鐵管件、不銹鋼襯層組成。

安裝便捷:通過卡箍件可實(shí)現(xiàn)管道自動(dòng)定心對(duì)中,有效縮短安裝工期。

安全可靠,卡箍內(nèi)腔的密封圈起到抓緊管道的作用,實(shí)現(xiàn)自緊密封,內(nèi)壓愈大,密封愈好。

安裝簡易,溝槽式管件需緊固的螺栓數(shù)量少,操作方便,不受安裝場地限制,維護(hù)方便。
