Abstract
Et rørlednings-inspeksjonsapparat omfatter en. rorledningspigg () som har en skakeanordning (20) for å bringe piggen til å vibrere i én eller flere av vertikal-, lengde-, tverr-, høye- og vridningsret-ningene. Vibrasjonene overfores til veggen til en. rorledning (2) som piggen beveges gjennom, og rørled-ningens vibrasjonsreaksjon måles ved hjelp av aksele-rometere (50-53) i piggen for detektering av én eller flere av piggens (1) vertikal-, lengde-, tverr-, boye- og vridningsbevegelser. For fremvisning og/ eller registrering av de målte data i en form som kan brukes til å identifisere variasjoner i rorled-ningens strukturelle tilstand, anvendes et dataakvi-sisjonssystem (38) ogen datamskin (36).A pipeline inspection apparatus comprises a. pipeline spike () having a shaking device (20) for causing the spike to vibrate in one or more of the vertical, longitudinal, transverse, height and torsional directions. The vibrations are transmitted to the wall of a. pipeline (2) through which the spike is moved, and the vibration response of the pipeline is measured by means of shaft-parameters (50-53) in the spike for detecting one or more of the spike (1) vertical, longitudinal, transverse, buoy and twisting movements. For displaying and / or recording the measured data in a form that can be used to identify variations in the structural condition of the pipeline, a data acquisition system (38) and a computer (36) are used.
