| 14º
metal seal |
 |
| This metal
seal is created by radial interference and is rated to the API minimum
collapse pressure rating for the pipe. The adjacent 900 surfaces
do not shoulder. |
|
| Two-step thread design | |
| This
nontapered noninterference thread form minimizes galling and thread-generated
stresses. |
|
| 14º reverse-angle torque shoulder | |
| This
torque shoulder positions the pin and box and receives over 80%
of the applied makeup torque. The shoulder is also the compressive
load-carrying element. |
|
| 14º metal seal | |
| This metal seal
is created by radial interference and is rated to the API minimum
internal yield pressure rating for the pipe |
|
| Formed pin and box members | |
| The pin
end is swaged inward and bored to ensure proper pin nose seal geometry
and guarantees higher tension efficiency without restricting its
driftability. The box is expanded and machined to a finished OD,
which allows higher tension and pressure sealing efficiencies. This
forming is done at ambient temperatures, prior to threading, and
the affected regions are then stress relieved by induction heating. |
