Abstract
A system and method for measuring a pipe is provided. The system includes a frame rotatably receiving the pipe, a carriage movably positionable along the frame, a guide floatingly positionable about the carriage, at least one sensor for measuring a position of the pipe, and a measurement unit operatively linked to the sensor for collecting measurements therefrom. The guide has a mouth that receivingly engages the pipe and axially aligns therewith. The pipe is measured with the sensor(s) while moving at least one of the pipe, the carriage and the guide.
Claims24
A system for measuring pipe, the system comprising:
- a frame rotatably receiving the pipe;
- a carriage movably positionable along the frame;
- a guide floatingly positionable about the carriage, the guide having a mouth that receivingly engages the pipe and axially aligns therewith;
- at least one sensor for measuring a position of the pipe;
- and
- a measurement unit operatively linked to the at least one sensor for collecting measurements therefrom.
A system for measuring pipe, the system comprising:
- a frame having an upper and lower portion, the lower portion rotatably receiving the pipe, the upper portion having rails positioned a distance above the lower portion;
- a carriage movably positionable along rails of the frame, the carriage having a carriage sensor that detects a position of the carriage along the rails;
- a guide floatingly suspended from the carriage, the guide having a mouth that receivingly engages the pipe and axially aligns therewith, the guide having a plurality of guide sensors positionable about the pipe and measuring a displacement thereof;
- a rotary sensor fixedly positionable about the pipe for measuring a rotational position of a marker on the pipe;
- and
- a measurement unit operatively linked to the carriage sensor, the plurality of guide sensors and the rotary sensor for collecting measurements therefrom.
A method for measuring pipe, comprising:
- providing a system for measuring the pipe comprising:
- a frame rotatably receiving the pipe;
- a carriage movably positionable along the frame;
- a guide floatingly positionable about the carriage, the guide having a mouth that receivingly engages the pipe and axially aligns therewith;
- at least one sensor for measuring a position of the pipe;
- and
- a measurement unit operatively linked to the at least one sensor for collecting measurements therefrom;
- measuring the pipe with the at least one sensor while moving at least one of the pipe, the carriage and the guide.
