       鋼襯聚四氟乙烯設備用于各種復雜化學環境下的重要的反應儲存設備,適用于常見的酸、堿、鹽、在不高于180攝氏度時的反應和儲存,該種設備使用無腐蝕不沾,使用壽命長,造價相對偏高,為什么造價會相對偏高呢是因為鋼襯聚四氟乙烯設備的制作流程繁瑣復雜技術含量高。

      內襯PTFE作業流程
      作業內容及重點
      一.工件檢驗
      1、如果是碳鋼基材的主要檢查:表面無氣孔、變形、砂眼、縫隙等焊接不良現象。
      2、如果是鏡面不銹鋼基材的主要檢查:外表面有無掛傷、內表面無氣孔、變形、砂眼、縫隙等焊接不良現象。
      二.前處理
      1、打磨:把工件表面的毛刺、焊碴、尖角、銳角等用角磨機仔細打磨。
      2、除油:空燒用400℃-420℃高溫除油,按工件大小、輕重設定保溫時間,徹底燒去素材殘余油質。
      3、表面粗糙化:噴砂用6公斤氣壓,20#金鋼砂表面均勻噴砂
      三. 內襯PTFE前處理
      1、架到滾輪架上,調整轉動效果。
      2、用空氣槍不低于6kg壓力,吹凈噴砂表面余塵。
      3、襯里前素材預熱干燥處理,除去表面殘留水份。
      四. 涂高溫膠
      1、把高溫膠提前1個小時充分和其它幾種配比好,然后倒進一個專用容器內進行攪拌混合。
      2、準備好刷子和滾筒
      3、帶好防護口罩、眼鏡和防塵服裝。
      五.膠水干燥
      24小時進行干燥,一定要保證自然干燥效果,以不粘手為標準,膠一共涂兩遍
      六. 貼PTFE板
      1、把事先裁減好的PTFE板一片一片貼到工件內。
      2、局部加熱然后用特殊工具把PTFE板內的空氣徹底擠出。
      七.焊接前準備
      1、首先把PTFE板與板進行整平。
      2、把板與板之間多余料用特殊工具修干凈。
      3、板與板接縫處進行開V型槽,以增強焊接強度。
      八.焊接
      1、清潔接縫處。
      2、焊接圓焊條,焊條采用PFA材質的。
      3、圓焊條焊接結束后,再焊一道扁焊條,作為對焊縫的二次加強。
      八.檢測
      1、用膜厚儀測量膜厚是否達到要求。
      2、 3mm至3.2mm防腐層就用20000V電壓垂直沿防腐層面低于50mm/s的速度進行100%的探傷,不產生白色火花為合格。
      九. 包裝
      保護法蘭面防腐層不受碰傷為標準。
      以上為鋼襯聚四氟乙烯設備的制作工藝流程,我公司長期供應鋼襯聚四氟乙烯反應釜、儲罐、管道、管件等化工設備,歡迎廣大客戶來考察!
