安(an)徽環瑞(rui)針對石化(hua)(hua)(hua)行業(例如原油(you)(you)、成品油(you)(you)、天(tian)然(ran)氣(qi)、加(jia)油(you)(you)站，石化(hua)(hua)(hua)企業的(de)油(you)(you)田、采油(you)(you)廠(chang)(chang)、煉油(you)(you)廠(chang)(chang)、化(hua)(hua)(hua)工廠(chang)(chang)、油(you)(you)庫、加(jia)油(you)(you)站、輸油(you)(you)汽)等(deng)滿足其易燃、腐(fu)蝕、高(gao)(gao)溫(wen)高(gao)(gao)壓惡劣環境下的(de)在線(xian)環保(bao)煙氣(qi)檢測，脫硫工程的(de)需要，研(yan)發生(sheng)產(chan)出石化(hua)(hua)(hua)專用的(de)防(fang)腐(fu)防(fang)爆耐高(gao)(gao)溫(wen)采樣伴熱管(guan)。那(nei)么(me)伴熱管(guan)的(de)安(an)裝應注意哪些(xie)事(shi)項呢？伴熱管(guan)與主(zhu)管(guan)之間(jian)的(de)連接件等(deng)要求等(deng)又有(you)哪些(xie)？

    伴(ban)(ban)(ban)熱管(guan)(guan)(guan)應(ying)與主(zhu)(zhu)管(guan)(guan)(guan)平行安裝，并(bing)應(ying)自行排液。當一根(gen)主(zhu)(zhu)管(guan)(guan)(guan)需要(yao)多(duo)根(gen)伴(ban)(ban)(ban)熱管(guan)(guan)(guan)伴(ban)(ban)(ban)熱時，伴(ban)(ban)(ban)熱管(guan)(guan)(guan)之間(jian)的距(ju)離應(ying)固(gu)定。水平伴(ban)(ban)(ban)熱管(guan)(guan)(guan)宜(yi)安裝在(zai)(zai)主(zhu)(zhu)管(guan)(guan)(guan)下方或(huo)靠近支架(jia)的側面(mian).鉛垂(chui)伴(ban)(ban)(ban)熱管(guan)(guan)(guan)應(ying)均勻分布在(zai)(zai)主(zhu)(zhu)管(guan)(guan)(guan)周圍，不得將(jiang)伴(ban)(ban)(ban)熱管(guan)(guan)(guan)直(zhi)(zhi)接點(dian)焊(han)在(zai)(zai)主(zhu)(zhu)管(guan)(guan)(guan)上.而(er)可采(cai)用綁扎帶或(huo)鍍鋅(xin)鐵絲等固(gu)定在(zai)(zai)主(zhu)(zhu)管(guan)(guan)(guan)上。彎(wan)頭部位的伴(ban)(ban)(ban)熱管(guan)(guan)(guan)綁扎帶不得少于3道，直(zhi)(zhi)伴(ban)(ban)(ban)熱管(guan)(guan)(guan)綁扎點(dian)間(jian)距(ju)應(ying)符合

 
    對不允許與主管直接接觸的伴熱管.在伴熱管與主管間應有隔離墊。當主管為不銹鋼管，伴熱管為碳鋼管時，隔離墊宜采用抓離子含量不超過5O5創8石棉墊，并應采用不銹鋼絲等不引起滲碳的材料綁扎。伴熱管經過主法蘭時，伴熱管應相應設置可拆卸的連接件。從分配站到各被伴熱主管和離開主管到收集站之間的伴熱管安裝，應排列整齊，不宜互相跨越和就近斜穿。安裝夾套管的連通管時，應盡盤焊接在夾套管的端頭處.防止套管內存液。套管端頭的水平連通管，宜用套管底部沿切線方向引出與接人。連通管安裝應便于操作與維修，盡最貼近套管.達到結構緊湊、外型美觀和定位可靠。夾套上多余的連通管管口，應在系統吹掃合格后隔熱施工前予以封焊。
