Withsol Co., Ltd. has been operating since its establishment in 1961 as a group of non-destructive testing specialists, expanding throughout Japan and taking pride in contributing to the quality assurance of top-tier Japanese industrial products, which are recognized as world-class. We are dedicated to the continuous improvement of non-destructive testing techniques day and night, ensuring the safety and reliability of first-class products. Furthermore, in the oil-related and power generation plants currently in operation, we provide non-destructive testing techniques as part of the maintenance of equipment, piping, and machinery, fulfilling our mission to contribute to the maintenance and management of safe and reliable plants. In particular, regarding the technology of "continuous plate thickness measurement" in crude oil and fuel tanks, we own numerous UDT and UDP devices that have received performance approval from the Hazardous Materials Safety Association (KHGK). We conduct inspections of tank bottom plates, side plates, roof plates, etc., across the country and take pride in the high evaluations we have received. Moving forward, we will continue to develop equipment for "special inspections" that can adapt to the progress of the times and engage in further research and development to introduce new non-destructive testing methods to the world. Under our corporate motto of "Trust, Effort, Safety," we will continue our unwavering efforts to provide reliable and reassuring inspections.
