Abstract
【解決手段】円筒状部材から形成された3種類の同軸管、即ち、熱膨張率の小さい材料から製造された内管2と、中間管3と、炭素鋼から製造された外管4とを含み、内管2と中間管3との間の環状スペースに断熱材7,8が配備された低温液体輸送用の熱絶縁されたパイプ。一方で、管2,3,4は連結継手5,6を用いて2つずつ連結されている。中間管3の円筒状部材3bは、組立の際に連結継手5,6と共働して内管2と外管4との間の熱伝導ブリッジの形成を阻止するために十分な長さに製造される。
【選択図】図1
Description
−アセンブリの熱効率が低下する、及び、
−外管の温度が低下し、このため、外管が脆くなり、衝撃や応力集中に弱くなる。
−一方では各管の円筒状部材のそれぞれを接続するため及び他方では管の温度変化の際の熱収縮によって生じる力を受容するために、管が連結継手を用いて2つずつ連結されていること、及び、
−中間管の円筒状部材が、組立の際に連結継手と共働して内管と外管との間の熱伝導ブリッジの形成を阻止するために十分な長さを有していること、
を特徴とする低温液体輸送用の熱絶縁されたパイプを提供することである。
−内管は約8mmよりも小さい肉厚を有している、
−中間管は15mmよりも小さく約6mmよりも大きい肉厚を有している、
−外管は約12mmよりも大きい肉厚を有している。
