Moscow Inspects 16K+ Gas Pipeline Welds
Dmitry Platov, head of the technical supervision management laboratory of JSC "Mosgaz": "Directly in the field, directly on the construction site, this mobile laboratory complex allows processing control results on the site with all conveniences.
Consensus
- Over 16,000 welded joints have been inspected on gas distribution networks in Moscow since the start of the year.
- Inspections are conducted using a combination of methods including X-ray, ultrasonic testing, and visual inspection.
- Domestic equipment is used, including robotic crawlers, digital data processing systems, and mobile laboratories.
- The goal of inspections is to ensure the safety and reliability of Moscow's gas distribution system.
- Results are processed on-site using mobile laboratory units, enabling rapid feedback.
Points of divergence
- The mobile laboratory complex was fully developed and manufactured by Mosgaz, allowing results to be processed within a maximum of one and a half hours on-site, significantly increasing labor productivity. — ntv
- The number of defective welds does not exceed 3-4%, and this year's inspections cover 400 more joints than in the same period last year. — m24
- X-ray is the primary method of expert inspection, used for 10,500 joints, with results from X-ray and ultrasonic methods sometimes compared for higher accuracy. — m24
