METHODS AND CONNECTIONS FOR COUPLED PIPE

摘要

A threaded and coupled connector with tapered threads having equivalent
heights (same height on pin and box threads), negative load flanks, biased
tapered thread forms with a torque shoulder formed by pin noses that abut at a
central point within a coupling constructed from standard coupling stock. The
connection design meets the internal/external pressure performance
requirements of industry standards with capabilities equal to or exceeding
those of "premium" connections, with a coupling constructed from thin walled
coupling stock.
