Abstract

Guarnizione metallica per testa di pozzo, destinata a congiungere in modo ermetico i componenti concentrici, interno ed esterno, della testa, costituita da una guarnizione metallica circolare avente una estremità piatta ed una estremità conica e disposta tra i componenti interno ed esterno. Un cono di forzaggio è disposto su uno dei componenti a contatto con l'estremità conica per realizzare la tenuta, uno spallamento di appoggio è a contatto con l'estremità piatta mentre i componenti interni ed esterni vengono spostati longitudinalmente durante la posa della guarnizione metallica. Un dado di regolazione adatta le tolleranze tra l'estremità conica ed il cono di forzaggio.
