ActiveTest method of pressure equipments of thermoplastics welded for chemicals—Part 3: Radiographic examination
化工用塑料焊接制承压设备检验方法 第3部分：射线检测
Application Summary AI generated
This standard specifies the radiographic examination method for detecting internal defects, such as cracks, porosity, and lack of fusion, in thermoplastic welded pressure equipment used in chemical industries. It is applied during manufacturing and in-service inspection of tanks, pipes, and vessels made from thermoplastics like PVC, PP, or PE, ensuring weld integrity and safety under pressure. The method is particularly relevant for quality control in chemical processing, storage, and transport applications where non-metallic welded structures must meet rigorous safety standards.
