Equipment take-over flange bolt hole mid-span problem
Thread Content
The mid-span problem of the bolt holes of the equipment nozzle flange has always been thought to be the north-south mid-span and the natural center span, as shown in attachments a and b. But today, someone from the Design Institute and someone from our technical department told me that the north-south crossing and the Nature Center are the same thing, and they are all A. I was confused.

b No, the lower bolts are corroded and installation is inconvenient.

This is also the first time for an engineering company to hear about the North-South Center Span and the Nature Center Span. In addition, the projects are all about pipes and equipment. Does your company first install the pipes and then install the equipment? Update device? Then there's nothing to say, just make it what it is.
It's definitely not wrong to make it a, but if you can't make it b, you may have to cut the flange.
I have been engaged in chemical equipment design for decades, and this is the first time I heard the terms North-South Cross-Center and Nature Center Cross-Center. Personally, I think this statement is purely pretentious.
I haven’t heard the original poster’s statement in more than ten years. I guess it’s a purely bureaucratic creation created by your factory leaders.
Isn't it in the middle of the span of the pipe? The pipe should be in the middle of the bolt?
