| 30º torque
shoulder and metal seal |
 |
|
This external torque shoulder
ensures the pin and box are exactly positioned and allows the application
of more-than-adequate torque to prevent downhole backoff. The 300
shoulder surface also creates a pressure seal capable of resisting
the API internal pressure rating of the pipe. |
|
| Center – step torque shoulder | |
|
This shoulder performs
as an additional torque shoulder, storing a small amount of torque
and helping to prevent overmakeup. |
|
| Two-step thread design | |
|
This nontapered, noninterference
thread form minimizes galling and thread-generated stresses. |
|
| 14º internal metal seal | |
|
This seal element is created
by radial interference and is capable of resisting the API internal
pressure rating of the pipe. The 140 angle minimizes rubbing between
the elements, which minimizes the possibility of galling. |
|
| Machined upset OD and ID | |
|
Upset OD and ID are machined
to closely toleranced dimensions to guarantee clearances and smooth
flow through the bore. |
