上海絕緣接頭與橡膠軟接頭的不同

時間:02-28󰃯閱讀次數:485󰃳責任編輯:那片海 󰃗所屬欄目:產品聚焦

導讀: 上海橡膠軟接頭是橡膠接頭,其中主要組成部分是有橡膠與金屬法蘭組成,而絕緣接頭卻不一樣,那么絕緣接頭是什么?與橡膠軟接頭有哪些不同?  上海絕緣接頭是同時具有埋地鋼質管道

 上海橡膠軟接頭橡膠接頭,其中主要組成部分是有橡膠與金屬法蘭組成,而絕緣接頭卻不一樣,那么絕緣接頭是什么?與橡膠軟接頭有哪些不同?

  上海絕緣接頭是同時具有埋地鋼質管道要求的密封性能、強度性能和電防腐蝕所要求的絕緣性能的管道接頭的統稱。它包含組合件、絕緣板、填料、密封環、短管等。

  上海絕緣接頭是根據絕緣法蘭在使用中存在的問題進行改進的換代產品,是鋼質管道保護系統中必不可少的重要壓力元件,廣泛應用于鋼制管道的保護系統。

  上海絕緣接頭與橡膠軟接頭安裝方式不同,安全有效的安裝絕緣接頭很重要,安裝后既要保證使用安全,也要能保證使用壽命。其中安裝中請注意以下八點:

  1、安裝處50m以內,不允許有待焊接死口;

  2、安裝處200m以內有管線死口時,其死口的焊接應在當地日平均氣溫(±5℃)內進行為宜;

  3、與管線連接后,不允許在5m內起吊管線,以免對絕緣接頭造成損壞;

  4、安裝在氣體介質管線時,不得安裝在管線埋設的低洼處;

  5、絕緣接頭的升降壓速度不得大于每分鐘0.5MPa;

  6、與管線連接后,應按管線補口要求進行防腐,防腐作業時不準使絕緣接頭表面溫度高于100℃;

  7、安裝前僅做絕緣性能測試(用500V搖表電阻應大于2MΩ且不低于標記數據,不宜再進行水壓試驗);

  8、絕緣接頭不得做為熱應力變形的補償件。
