Title:
管の非接触オンライン式高温壁厚測定方法と装置
Document Type and Number:
Japanese Patent JP4039546
Kind Code:
B2
Abstract:
Laser-ultrasound technique is used to scan a segment of the pipe wall in circumference direction, during or after the rolling process. Mathematical analysis and symmetry observations are used in a computer to reconstruct the wall of the pipe cross-section. By using several measuring heads that are swivelable in the circumference direction, each head covers a different allocated section of the pipe wall. An Independent claim is included for an apparatus for contactless hot-wall thickness measurement.
