Specialists from the Moscow City Services Complex checked more than 16.5 thousand welded joints on gas pipelines. Almost 12 thousand of them were examined using X-ray flaw detection, and the remaining 4.8 thousand were examined using ultrasound.
The ultrasonic flaw detection method is based on recording the vibrations of ultrasonic waves. They are reflected from the surfaces of gas pipelines, including weld defects, and a special device shows deviations in real time. For X-ray flaw detection, appropriate installations are used: the rays pass through the metal, and the quality of the connections is recorded on film or digital media.
During the inspection, specialists of JSC Mosgaz use advanced technologies, including self-propelled crawler systems with X-ray machines and highly sensitive film. The inspection results are available immediately on site thanks to a mobile laboratory built on the basis of KamAZ – the company’s own development.
The use of modern technologies allows us to identify even the most minor defects that are invisible to the human eye, thereby ensuring the reliability and safety of gas pipelines throughout their entire service life.
