Why doesn’t our factory like to use DN32? Do they not like this number?
It’s non-standard, so it’s used less often. I think

Our company still doesn’t like to use pipe size 40; I truly think it’s superstition that causes problems
It’s not your factory; everyone doesn’t use it much. Refer to the guidelines posted above
32, 65, and 125 all correspond to American standard pipe sizes; if you use HG or GB standards, these options are less suitable； Hydrogenation and other secondary processing units in U.S.-standard refineries are widely used ； Standard American models have fewer pressure rating options, making it easier to obtain spare parts
@7th floor, “Fewer pressure ratings for US standards”? ~~~~That’s because you haven’t heard of 75Lb~100lb~125lb~~~450lb~~~~~
Generally, people try to use data that is standardized, normalized, and highly versatile
For example, the API610 standard specifies that specifications such as 32, 65, 90, 125, 175, and 225 should not be used
