Control valve and pipeline connection form

When to weld and when to use flange connection, please give me some advice!
What does the landlord mean? Regulating valves are generally flange-connected. All diameters are flanged. If you weld it, do you have to cut it off every time you inspect it? Of course, special working conditions are not excluded.
Usually flanges, but also clamping type, small diameter ones with threads. I have never seen welding, because the possibility of a problem with the regulating valve is relatively high, and replacement should be considered. 1# Ocean Wind
Just make sure that the regulating valve can be disassembled and see which structure is reasonable.
