Abstract:
An apparatus for straightening a coiled tubing has an injector that receives the coiled tubing, a straighter that straightens the coiled tubing from the injector, and a shear that cuts the straightened coiled tubing. The straightener has a frame having a first section rotatably connected to a second section, an actuator connected to the second section, and a straightening wheel connected to the actuator. The injector has a first drive chain and a second drive chain. The first and second drive chains each have semi-circular members forming circular channels that grab an outer surface of the coiled tubing. The shear has a trolley, a clamp, a tubing cutter, a return mechanism, and an automated controller. The automated controller actuates the clamp and the tubing cutter while the trolley translates along rails from a first position to a second position.
