The inventions relate to pipe connections mostly for extreme conditions of high and low pressure, deep vacuum, high and low temperatures, in corrosive media and so on, and can be applied to automotive, aviation, aerospace, nuclear, shipbuilding and other industries. Pressurization is achieved by using an elastic insert that is properly positioned when put inside or outside a centering adapter allowing them both to remain in contact during their reciprocal movement, so that the alignment is ensured and a transverse shifting of the centering adapter is prevented. While pulling the pipes together, equalization of the contact pressures on the torus-shaped projections is maintained. In the second variant, not less than two flat split adjustment rings are installed from either side of the centering adapter, pulling the pipes together is done up to a moment when entire contact is reached between the faces of the conjugated pipelines, adjustment rings and faces of the centering adapter. The seal is equipped with a centering adapter that is put coaxially to the elastic insert allowing their contact during reciprocal axial movement. Claimed herewith are 4 independent and 10 dependent claims. |
