    NonDestructive Testing
    The company has been providing NDT service since 1991, having constant development of technology and personnel. From stable customers such as Government Invested Company(Korea Gas Service, Korea Electricity and Power Company, Korea District Heating Corporation etc.) and Hyundai Heavy Industry Co., Ltd., we render NDT service for Gas pipe, Oil Pipe, Power Plants, Ships, Bridges, Buildings, Vessel and Tanks.
    NDT technology was introduced to Korea in early 1960's and settled down, because of increase of construction of oil chemistry plants, power plants, development of heavy chemical industry andincrease of demand for NDT.

    We are expecting service experience will be prospering especially for the development of national defense industry and nuclear energy industry which needs high level of reliability and safety.

    A nondestructive test has been mainly used for the quality management of products, and its main application areas are ship, bridge, gas pipe, oil pipeline, pressured container, power plant, and cultural asset. The nondestructive test has a purpose not only to find the defects in materials and welding joints of the above products and to procure the reliability of products, but also to improve and enhance the manufacturing technology to reduce the cost. Also, through periodic inspection, the test has been used to enhance the reliability of products by preventing the risk due to destruction in advance and eliminating the damage
