A.
The better insulation material should be put just next to pipe (i.e., inside) |
|
B.
The better insulating material should be put outside |
|
C.
Either of the insulating material could be put on either side |
|
D.
Steam temperature is considered before deciding as to which insulating material is to be put inside (i.e., just next to the pipe) |
