ABSTRACT:
An injector for flexible tubing has endless drive conveyors on opposite sides of a pathway for the tubing. The drive conveyors include gripper blocks that work in opposing pairs along the tubing pathway. The pairs of gripper blocks are clamped to the tubing and moved along the tubing pathway to either inject the tubing into a well or withdraw the tubing from a well. The gripper blocks are clamped to the tubing by way of skates, which work in opposing pairs. The skates have rollers, with rollers contacting the gripper blocks. Each roller has two ends, which ends are received by bearings inside of mounts on the respective skate.
