Appendix F of GB/T 150-2024: Discussion on the impact test temperature when the design temperature is lower than the minimum operating temperature specified in GB150.2
Thread Content
1.GB/T 150.3 Appendix F: Method for checking pressure vessels against low-temperature brittle fracture. When the design temperature is lower than the minimum operating temperature specified in GB 150.2, is it still necessary to conduct impact tests on the raw materials and welded joints at that design temperature?
That’s a good question; I don’t understand it either right now
