THREADED PIPE JOINT

Provided is a threaded pipe joint 5 in which under a tensile load, fracture on the female thread side of the first thread portion of the second thread row (B) continuous with the intermediate shoulder (C) is avoided, and tensile fracture certainly occurs on the female thread side of the first thread portion of the first thread row (A), which is the location of the normal critical crosssection. Under a condition where the female and male threads of the intermediate shoulder (C) are engaged with each other, the load-flank-side thread gap L1G of a first thread row (A) that is the thread row on the radially inner side and the load-flank-side thread gap L2G of a second thread row (B) that is the thread row on the radially outer side, with the intermediate shoulder (C) interposed therebetween, always satisfy the relationship L1G < L2G.
