Profile: Dandong Aolong Radiative Instrument Co., Ltd. is a manufacturer of NDT, analyzing and imaging equipment. Portable directional X-ray flaw detectors ( glass X-ray tube ) can be used in non destructive testing (NDT) of thin iron plate, aluminum material, and rubber. Portable panoramic X-ray flaw detector can be used in non destructive testing of welding line of pipe with small diameter. Connected with carrying wheel or pipeline creeping device, the portable panoramic X-ray flaw detector can be put into the pipeline easily. Its controller also can be put into the pipeline with the generator. X-ray diffractometer systems are widely used for determining the phases nature and analyzing ration of sample, measuring macroscopical stress, microscopical stress & crystal particle size. The X-ray diffractometer systems can be used widely in material science, physics, chemistry, metallurgy, mineral science, archeology, detective technology, inspecting commodity, producing medicament, plastic, and chinaware. X-ray diffractometer systems are necessary equipment for analyzing material in universities, scientific research institutions and material factories. The X-ray diffractometer systems have various characteristics including precise design, perfect function for all kinds of analyzing, such as analyzing microscopical structure, analyzing crystal structure, determining phases nature & ration analyzing , indexing diffraction chart & measuring array parameters, measuring rest stress, and analyzing structure.
