| description | An objective of the present invention is to provide a threaded connection for pipe or tube having an excellent anti-misalignment property and an appropriate shouldering torque, and further having excellent corrosion resistance and an excellent adhesiveness of a solid lubricant coating, and to provide a method of producing the threaded connection for pipe or tube. The threaded connection for pipe or tube according to the present embodiment includes a pin (13) and a box (14). The pin (13) and the box (14) have contact surfaces including thread portions (15) and (20) and unthreaded metal contact portions. The threaded connection for pipe or tube comprises an alloy plating layer (21) consisting of a Zn-Ni alloy on the contact surface of at least one of the pin (13) and the box (14), a phosphating layer (22), and a solid lubricant coating (23). These are stacked in an order of the alloy plating layer (21), phosphating layer (22), and the solid lubricant coating (23), from a contact surface side. (FIG. 5) |
