Threaded connection for oil country tubular goods and composition for photocurable coating |
| abstract |
This invention provides a threaded connection for oil country tubular goods that can suppress an increase in torque when making up a pin and a box in a cold climate. A threaded connection for oil country tubular goods (1) of the present embodiment includes a pin (2) and a box (3). The pin (2) and the box (3) each have a contact surface (21), (31) that has a thread portion (22), (32) and an unthreaded metal contact portion (23), (33). The contact surface (21) of the pin (2) includes a photocured coating (25) as an uppermost layer. The photocured coating (25) contains a photocurable resin and perfluoropolyether. The contact surface (31) of the box (3) includes a solid lubricating coating (35) as an uppermost layer. |
