Beschreibung
Zusammenfassung:	The improved joint of the present invention includes a wellhead housing (12) and its complementary member(16)forming the joint and they include surfaces(36,48) which taper both inwardly and away from the joint surfaces together with straight cylindrical sealing surfaces (38, 50) extending away from the inner end of the tapered surfaces. One form of improved seal includes a sealing ring (52) having a tubular body with an external flange or hub (56) to be clamped between the joint surfaces of the joint members, tapered external surfaces (58, 60) which mate with and provide a tight sealing engagement with the tapered surfaces (34, 48) of the joint members and tubular rims (62, 64) extending away from the tapered surfaces and having sufficient length to protect the straight cylindrical sealing surfaces (38, 50) of the joint members. A modified form of improved seal includes a sealing ring having a tubular body with an external flange to be clamped between the joint surfaces of the joint members, and tubular rims terminating in an external rounded portion having a short annular flat sealing surface thereon for engaging the straight cylindrical sealing surfaces of the joint members at a position spaced axially from the tapered sealing surfaces of the joint memebers.
