Abstract

The invention relates to a joint for steel pipe, which is oil-tight at high pressure, being of the type including at least one pair of slightly conical sealing surfaces arranged at at least one end of the male member or of the female member, and is insensitive to seizure. This joint is characterized by the fact that the first contact 5 of the sealing zone lying at the end of one member occurs against the corresponding sealing surface of the other member and that at the time of this first contact the taper of the sealing surface which is situated at the end of one of the members of the joint is less than the taper of the corresponding sealing surface which is situated on the other member of the joint, the sealing surfaces at the time of tightening the joint, becoming applied against one another with a contact pressure sufficient to ensure oiltightness.
