inner pipe diammeter measurement

I should measure the inner diameter of seem less pipes in the range of 144 mm up to 273 mm with a precision of 0.01.
Could somebody help me?.

Re: inner pipe diammeter measurement
You can use ultrasound, see: http://www.ndt.net/article/rohrext/us_dia/us_dia_e.htm

I believe that krautkramer or Panametrics deliver such system.

Fallon Ultrasonics sells pipe diameter measurements system having accuracy of 1 micron. System measures wall thickness (true and average), OD and ID (true and average) ovality and eccentricity. Data are displayed on chart recorded formate and very high speed. System are being used in nulcear industires with flaw system at surface speed of greater than 2 m/s. Please contact me if you need further information. For the measurement accuracy both sensor and system should able to respond to slight variation in positon of tube with repsect to sensor position.

Regards

oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
