| description | PROBLEM TO BE SOLVED: To provide a double pipe sealing material capable of being easily attached to an inner cylindrical pipe and sealing between the inner cylindrical pipe and an outer cylindrical pipe.SOLUTION: A double pipe sealing material 10 seals by attaching a filler, which is filled between an outer cylindrical pipe 1 and an inner cylindrical pipe 2 inserted into the outer cylindrical pipe 1 of a double pipe and connects and fixes the outer cylindrical pipe 1 and the inner cylindrical pipe 2, to a seal material fitting part 5 on the inner cylindrical pipe 2. The double pipe sealing material 10 comprises: a first annular seal part 11 made of elastic material, which supports load from the filler that is attached and fixed to the seal material fitting part 5 and filled; and a second annular seal part 12 made of elastic material, which is formed on the first seal part 11, absorbs a circumference difference between the inner cylindrical pipe 2 and the outer cylindrical pipe 1 by changing volume or changing shape in a pipe axial direction and can closely contact with the inner peripheral surface of the outer cylindrical pipe 1.
【課題】シール材を内筒管に簡単に取り付けることができ、外筒管との間をシールすることができる２重管用シール材を提供する。【解決手段】２重管用シール材１０は、外筒管１と、外筒管１に挿通される内筒管２との２重管の間に充填され外筒管１と内筒管２とを連結固定する充填材を、内筒管２に設けたシール材取付部５に取り付けてシールする２重管用シール材で、シール材取付部５に取り付けて固定され充填される充填材による荷重を支持する弾性素材で形成された環状の第１のシール部１１と、第１のシール部１１に設けられ弾性素材で形成され外筒管１との間の周長差を体積変化又は管軸方向への形状変形で吸収して外筒管１の内周面に密着可能な環状の第２のシール部１２とを備える。【選択図】図３ |
