Title (EN) PIPE JOINT
(FR) RACCORD DE TUYAU
(JA) 管継手
Abstract:
(EN) A pipe joint which connects: a first pipe that has electrical conductivity and is connected to the ground; and a second pipe that comprises a corrugated metal tubular member and a conductive layer which covers the tubular member and has a lower electrical resistance than the metal that constitutes the tubular member. This pipe joint is provided with: a connection part which has electrical conductivity and is connected to the first pipe; a container part which has electrical conductivity and fits with the connection part, while containing the second pipe inside by having the second pipe inserted thereinto along the axial direction of the second pipe; and a conductive member which has a first portion that is in contact with at least a part of the container part and a second portion that is exposed to the outside of the container part, thereby being in contact with the conductive layer.
(FR) Raccord de tuyau qui raccorde : un premier tuyau qui présente une conductibilité électrique et est raccordé à la terre; et un second tuyau qui comprend un élément tubulaire métallique ondulé et une couche conductrice qui recouvre l'élément tubulaire et présente une résistance électrique inférieure à celle du métal qui constitue l'élément tubulaire. Ce raccord de tuyau est pourvu : d'une partie de raccordement qui présente une conductibilité électrique et est raccordée au premier tuyau; d'une partie récipient qui présente une conductibilité électrique et s'ajuste avec la partie de raccordement, tout en contenant le second tuyau à l'intérieur par le fait que le second tuyau est introduit dans celui-ci le long de la direction axiale du second tuyau; et d'un élément conducteur qui comporte une première partie qui est en contact avec au moins une partie de la partie de récipient et une seconde partie qui est exposée à l'extérieur de la partie récipient, étant ainsi en contact avec la couche conductrice.
(JA) 導電性を有するとともに接地された第1の管と、コルゲート加工された金属製の管状部材および管状部材を構成する金属より低い電気抵抗を有するとともに管状部材を覆う導電層を備える第2の管と、を接続する管継手であって、導電性を有し、第1の管と接続する接続部と、導電性を有し、接続部と嵌まり合い、第2の管の軸方向に沿って第2の管が挿入されることにより第2の管を内側に収容する収容部と、収容部の少なくとも一部と接触する第1部分と、収容部の外側に露出して導電層と接触する第2部分と、を有する導電性部材と、を備える、管継手。
