Over the past 40 years of reform and opening up, China's industry has undergone earth shaking changes. The power industry is moving from being made in China to being intelligently manufactured in China, and the unit parameters have developed from high-voltage parameters to subcritical, supercritical, and ultra supercritical parameters. The "700 ° C Plan" currently being developed is at the forefront of the world, and the power grid has also developed to long-distance transmission such as ultra-high voltage AC and DC. Power equipment has moved from imported from the world to exported to the world, Ultrasonic testing has made outstanding contributions in this development process.
To ensure the safety of power equipment, ultrasonic testing technology has made significant progress, and new technologies are constantly emerging and improving. Thermal power plants, power grid enterprises, power maintenance companies, universities, research institutes, testing institutions, training companies, and other ultrasonic testing technicians need to use steam turbine generator alloy bearing shells, bolts, power plant three-way elbows, pillar porcelain insulator porcelain sleeves, steam turbine spindles, generator blades, and other testing and verification require corresponding standard test blocks and comparative verification test blocks, which are also produced by our company.
