    Penetration Testing

    NDT of surface defects may be required for raw materials, production process and in-service period, but penetration testing can be used when magnetic particle testing is not possible due to limited structure and material. In some cases, penetration testing can also verify whether the flaw has penetrated. CTI has a variety of penetrating materials, which can provide customers with fluorescent and dye penetration testing, and escort their products.
