Abstract

See full text

A gas-tight joint for pipe linings and risers inside a bore, consisting of a neck with an outside thread and of a matching collar with an inside thread, with a groove in the vicinity of the thread on the collar and/or of the thread on the neck to accommodate a deformable gasket that, when the joint is screwed tight, is demarcated and deformed by the base of the groove in the neck and/or in the collar and by the contour of the thread on the other component. The cross-sectional area demarcated by the base of the groove in the neck and/or collar and by the contour of the thread on the other component once the two components have been screwed together remains constant along the groove and is equal to or larger than the cross-sectional area of the deformable gasket before the components are screwed together.
