メタルガスケット
Abstract:
(EN)
Provided is a metal gasket, which is used for connecting pipes to each other in a thermal power plant, a nuclear power plant, a steam engine in a steam turbine ship, an oil refinery line, a petrochemical industry process line, a semiconductor manufacturing line, or the like, and which is characterized in that a V-shaped circumferential groove 2 is provided on the outer circumferential surface of the metal gasket 1, the ratio (circumferential groove depth A/horizontal length B) of the depth A of the circumferential groove 2 and the horizontal length B in a cross section of the metal gasket 1 is 0.1–0.95, and the cutting angle of the V-shaped groove 2 is 30°-120°.
(FR)
L'invention concerne un joint métallique, qui est utilisé pour raccorder des tuyaux entre eux dans une centrale thermique, une centrale nucléaire, un moteur à vapeur dans un navire à turbine à vapeur, une ligne de raffinerie de pétrole, une ligne de traitement de l'industrie pétrochimique, une ligne de fabrication de semi-conducteur ou similaire, et qui est caractérisé en ce qu'une rainure circonférentielle en forme de V (2) est disposée sur la surface circonférentielle externe d'un joint métallique (1), le rapport (profondeur A de rainure circonférentielle/longueur horizontale B) entre la profondeur (A) de la rainure circonférentielle (2) et la longueur horizontale (B) dans une section transversale du joint métallique (1) est de 0,1 à 0,95, et l'angle de coupe de la rainure en forme de V (2) est de 30° à 120°.
(JA)
火力発電所、原子力発電所、スチームタービン船の蒸気機関、石油精製ライン、石油化学工業のプロセスライン、半導体製造ラインなどにおける配管同士を接続する際に用いられるメタルガスケットであって、メタルガスケット1の外周面にV字状の円周溝2を有し、円周溝2の深さAとメタルガスケット1の断面における水平方向の長さBとの比(円周溝の深さA/水平方向の長さB)の値が0.1~0.95であり、V字状の円周溝2の切込み角度が30~120°であることを特徴とするメタルガスケット。
