Tubing injector with built in redundancy |
摘要 |
A tubing injector has a first injector pair and a second pair of cooperating injector mechanisms. The first injector pair are positioned on a first track and the second pair are positioned on a second track. The tubing injector provides redundancy to address safety concerns. The first injector pair is movable to the engaged position, when the second injector pair is moved to the disengaged position and vice versa. |
