Abstract

A threaded joint for oil well pipes has excellent leak-tightness and a high disconnect torque and can withstand repeated make-ups. At the time of make-up, the load flanks (1) of the male and female threads contact each other, either the crest surfaces (3) or the root surfaces (4) are contacting and the other of the two pairs of surfaces has a gap, and a gap of at most 0.03mm exists between the stab flanks (2) of the male and female threads.
