Big Valve Questions

I wonder how long/how many passes it takes to weld this into the line, multiple shifts?

The photo is from a Velan catalog, it's a 36", not sure of the rating.

For this size valve, are welded ends the best way to go (as opposed to flanges)? The guts should be easily serviced through the bonnet.
