Abstract
A measuring device for a tube is disclosed. The measuring device includes a drift tool configured to verify roundness of the tube, a first electromagnetic (EM) emitter disposed on the drift tool and configured to emit EM waves while the drift tool drifts inside the tube, and an EM receiver disposed on the drift tool and configured to receive the EM waves reflected from an internal surface of the tube, wherein parameters of the emitted and received EM waves are analyzed to compute an internal diameter of the tube.
Claims18
A measuring device for a tube, comprising:
- a drift tool configured to verify roundness of the tube;
- a first electromagnetic (EM) emitter disposed on the drift tool and configured to emit EM waves while the drift tool drifts inside the tube;
- and
- an EM receiver disposed on the drift tool and configured to receive the EM waves reflected from an internal surface of the tube,
- wherein parameters of the emitted and received EM waves comprising a wavelength, a wave incidence angle, and a wave travel time of the EM waves, are analyzed to compute an internal diameter of the tube.
A method to measure a tube, comprising:
- disposing a drift tool inside the tube to verify roundness of the tube;
- disposing a first electromagnetic (EM) emitter on the drift tool that emits EM waves while the drift tool drifts inside the tube;
- disposing an EM receiver on the drift tool that receives the EM waves reflected from an internal surface of the tube;
- analyzing parameters of the emitted and received EM waves to compute an internal diameter of the tube;
- causing, using at least one of:
- a vacuum pull through mechanism, a compressed air pull through mechanism, and a rope pull through mechanism, the drift tool to drift inside the tube at a predetermined speed;
- and
- determining, based on the parameters of the emitted and received EM waves, a gap distance between the internal surface of the tube and a cylindrical surface of the drift tool,
- wherein the internal diameter of the tube is determined as a sum of the gap distance and a predetermined outer diameter of the drift tool, and
- wherein the parameters of the emitted and received EM waves comprise a wavelength, a wave incidence angle, and a wave travel time of the EM waves.
