In May 2026, T-ALL Inspection’s NDT team successfully completed an integrated annual maintenance NDT and physicochemical testing project for a thermal power plant in Xinjiang. The successful implementation of this project marks a further enrichment and upgrade of T-ALL Inspection’s power industry solutions, building on the company’s existing services in power plant leak detection and vacuum system helium leak testing. It also adds valuable practical experience to T-ALL Inspection’s brand development in the energy sector.

The thermal power plant is a key local combined heat and power enterprise, equipped with 2×350 MW supercritical coal-fired air-cooled generating units. It undertakes important responsibilities for urban heating and power supply to the industrial park. As its core equipment operates under long-term high-temperature and high-pressure conditions, the quality of metal structures and welds is directly related to the safe operation of the units. This annual maintenance project involved heavy workloads and high technical requirements. Focusing on key facilities such as boilers, turbine generator units, high-temperature and high-pressure pipelines, and pressure vessels, the team carried out comprehensive NDT services including radiographic testing, ultrasonic testing, magnetic particle testing, penetrant testing, and PAUT (Phased Array Ultrasonic Testing), as well as physicochemical tests such as hardness testing, metallographic examination, and spectral analysis. Through detailed inspection of potential safety hazards, the team helped build a solid foundation for the safe and stable operation of the units.

Facing the harsh Gobi environment, unfamiliar working conditions, and high-standard requirements, the team rose to the challenge. T-ALL Inspection established a dedicated technical team, developed an integrated inspection plan in line with industry standards, and completed all preparatory work in advance. During on-site operations, all team members worked in shifts, overcoming challenges such as wind and sand, confined spaces, and cross-construction activities. By strictly following safety regulations, the team achieved zero accidents and zero errors. With advanced inspection technologies such as phased array ultrasonic testing, combined with physicochemical testing, the team accurately identified equipment defects and evaluated material conditions, providing reliable technical support for the unit maintenance work.

For complex defects discovered during the maintenance process, the team conducted overnight technical discussions to optimize inspection procedures and worked together with the power plant to develop treatment solutions, efficiently completing the closed-loop defect management process. During this project, the team completed inspections of thousands of welds and hundreds of physicochemical tests, identified multiple equipment hazards, and ensured that all inspection data successfully passed acceptance and complied with industry standards, providing strong support for grid connection and safe operation of the units.

The successful completion of this project is an important practice for T-ALL Inspection in continuously expanding its presence in the power and energy market, as well as a vivid demonstration of the team’s perseverance, innovation, and technical breakthroughs. The project further verified T-ALL Inspection’s technical strength and integrated service capabilities in power equipment NDT and physicochemical testing. It also accumulated valuable experience in large-scale power plant maintenance operations, standard implementation, and safety management, laying a solid foundation for further deepening T-ALL Inspection’s market presence in the power inspection sector and serving more energy clients in the future.
