Answer Posted / shankar
Clarification:
There are four end connections:
1. Butt weld
2. Socket weld
3. Threaded end
4. Flanged end
For butt welded and socket welded end valve, schedule is
important. For other no need.
But while connecting a pipe and a flange, schedule is
needed.
For joining any two components (a pipe with a valve)
through butt welding, ID of both should be match.
Pipe is designated by a "Nominal Pipe Size" based upon the
ID (inside diameter) of the most common wall thickness.
Tubing is designated by the measured OD (outside diameter).
