Abstract (en)
[origin: WO2020254349A1] A tubular connection includes either or both of a pin or a box. The pin includes an external male threaded zone having external male threads disposed on a portion of the pin, and the box includes an internal female threaded zone having internal female threads disposed on a portion of the first box. The internal female threads are configured to engage with the external male threads of the first pin. At least one of the pin or the box includes a torque shoulder surface that includes a surface roughness that is greater than or equal to 100 microns. In some instances, the torque shoulder surface can include a knurled surface profile that is continuous along the torque shoulder surface. In certain instances, a second mating torque shoulder surface has a surface roughness greater than or equal to 100 microns.
