–NB1 1/2 ″ à 20 ″ API de notation de classe 6A
Joint de type RX
Les joints RTJ de type RX sont fabriqués conformément à la fois avec les brides API 6A et ASME B16.20 pour convenir à l'API 6B et ASME / ANSI B16.5.
Style Rx est une adaptation à la pression du joint R de style standard. Le RX est conçu pour s'adapter au même design de rainure qu'un style standard R, ce qui rend les joints interchangeables. La conception modifiée utilise un effet activé par pression qui améliore l'efficacité du joint à mesure que la pression interne du système augmente.
