Abstract

A tubular connection is formed by a box member and a pin member, each of which has a tapered constant pitch thread. A profile defined by the thread of at least one of the pin member and the box member results in a pitch line that is a stepped pitch line. The stepped pitch line configuration may produce a wide radial band of substantive contact between the stab flanks of the pin member and box member upon full make-up of the connection.
