1. What is the difference between grade II and grade III forgings? 2. Why can the mean diameter formula be used in the design of high-pressure vessels? 3. What are the principles for setting up saddle supports for horizontal containers? 4. What are the structural design features of high-pressure vessels?
Come in and learn* for a bit – why isn’t anyone answering? ?
Difference between grade II and grade III forgings: In addition to tensile and impact tests, grade III forgings also require ultrasonic testing. Grade III forgings must be inspected one by one, whereas for grade II forgings, only one sample per batch needs to be inspected.
According to the forging factory, it’s mainly due to differences in testing methods (testing ratios). The materials and such are the same during the manufacturing process
