EXPANSION JOINT

An expansion joint is used to accommodate changes in length of above-ground pipe lines due to thermal expansion. A tube is surrounded by a ring attached to a sleeve. One end of the tube is attached to a pipe of the pipeline, one end of the sleeve is attached to another pipe of the pipe line. The tub...

Zusammenfassung:	An expansion joint is used to accommodate changes in length of above-ground pipe lines due to thermal expansion. A tube is surrounded by a ring attached to a sleeve. One end of the tube is attached to a pipe of the pipeline, one end of the sleeve is attached to another pipe of the pipe line. The tube and the ring and sleeve are movable axially relatively to one another when the pipe line expands or contracts linearly. A seal between the ring and the tube ensures fluid tightness of the joint. Linvention porte sur un joint de dilatation utilisé pour compenser les variations de la longueur de canalisations tubulaires montées au-dessus du sol qui résultent de la dilatation thermique. Un tube est entouré dune bague attachée à un manchon. Une extrémité du tube est fixée à un tube de la canalisation et une extrémité du manchon est fixée à un autre tube de la canalisation. Le tube, la bague et le manchon sont mobiles dans la direction axiale lun par rapport à lautre lorsque la canalisation se dilate ou se contracte linéairement. Un joint entre la bague et le tube assure létanchéité du joint.
