On a high torque connection once torque is being applied the pin connection will stretch slightly until the secondary torque shoulders/mechanical stops come into contact with each other and then recommended makeup torque is achieved. I determine the refaceability of a connection by referencing the pin or box bench mark and if a bench mark is not present (some machine shops dont re-apply bench marks when recutting) I measure the pin length or box counterbore length to assess refaceability. 0000113102 00000 n Non-API Drill Pipe Connection Thread Types H-90 Connections This secondary torque shoulder is not a seal.
