High end inspection by filmless radiography on LSAW large diameter pipes

摘要

Longitudinally submerged arc welded pipes for gas and oil transportation are subject to the most severe safety requirements. To further enhance the NDT process, EUROPIPE as a manufacturer of large diameter pipes for the oil and gas industry has invested in the digital X-ray inspection technology and herewith completely replaces the X-ray film. The new installation consists of two separate X-ray chambers in order to keep up with the production flow. In each chamber two digital detector arrays and two X-ray tubes are installed. This installation replaces three old X-ray chambers with twelve X-ray tubes. The installation is the result of long-term research and development in the field of X-ray testing. The installation is one of the first implementing this technology in an automated serial production of large diameter pipes.
