Future development of cryogenic air separation equipment

According to the structural characteristics of the valve casing castings, generally take X-rays or γ-rays as a source of radiation with the technical measures of the way the valve body pressure-bearing parts for radiation detection. The use of radiation detection technology to detect the valve body pressure parts, you can find internal defects in the casting, to avoid casting defects may lead to valve leakage and lead to deflagration or explosion accidents. X-ray inspection is often used...
