Is pipe material different than pipe fittings ...... ??

Look at it this way:
A big truck (lorry) pulls in to your job site.
You ask "what on that truck?"
The yardman says "that's the piping material!"
You ask "What piping material?"
He says, "That is the pipe, fittings and valves."
You ask "What fittings?"
He says " The elbows, the TEEs, the Reducers, the flanges, the O-Lets for the branches, you know, the fittings"
You say, "Oh"

hi Engr_mech

Generally, the chemical composition between pipe and fitting are almost same in a line. Only but the standards applied may be different. And we consider the materials are same.
