A landing pipe includes a first tool joint, a second tool joint, and a main section extending from the first tool joint to the second tool joint, the main section having a first portion and a second portion. The first tool joint outer diameter is greater than both the main section first portion outer diameter and the main section second portion outer diameter. The main section third portion wall thickness is greater than the main section second portion wall thickness, and the main section second portion has a length range of 40% to 85% of an overall length of the landing pipe.

Landing pipe

A threaded connection for drilling or working hydrocarbon wells includes first and second tubular components with an axis of revolution, each including respective male and female ends. At least one of the male or female ends finishes in a terminal surface including a first abutment surface that can come into interfering contact when the connection is made against a second abutment surface provided on a shoulder produced on an opposing tubular component male or female end. At least one of the first and second abutment surfaces is hollowed out by a groove, defining an exterior abutment zone and an interior abutment zone. In the connection made state, the exterior and interior abutment zones are not coplanar, such that contact pressure of the interior abutment zone exerted in a vicinity of the groove is greater than or equal to a minimum value for contact pressure exerted in the exterior abutment zone.
