The minimum thickness of the cylindrical shell after processing and forming shall not be less than 3mm for carbon steel and low alloy steel containers, which does not include (). A. Corrosion allowance ； B. Negative deviation of steel thickness ； C. Processing thinning amount ； Why do so many people choose AC?
Choose A. The theme is the original words of the book.
If you tell them it's a multiple-choice question, it shouldn't be wrong.
It’s stated in the question (single choice, single choice, single choice);P
Do they have other different opinions?
Friends who choose C, the processing thinning amount is a bit strange. They all said that it is equivalent to the minimum thickness of the shell when it is delivered to the user unit after forming.
This mainly affects the head seal. It can be said that the finished product obtained minus the corrosion margin is no less than that standard value.
This regulation corresponds to the appearance and geometric dimension inspection during the container manufacturing process. It actually refers to the actual measured thickness. Since it is the actual measured thickness, after it has been formed, how can there be any processing thinning amount?
Since it is after molding, there should not be any talk about the amount of processing thinning.
