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 of the present embodiment includes a pin and a box. The pin and the box each have a contact surface that has a thread portion and an unthreaded metal contact portion. The contact surface of the pin includes a photocured coating as an uppermost layer. The photocured coating contains a photocurable resin and perfluoropolyether. The contact surface of the box includes a solid lubricating coating as an uppermost layer. |
