1.
The documentation on piping symbols used on drawings is sponsored by

B)isometric drawing.
C)double-line drawing.
D)schematic drawing.
3.
On a single-line pipe drawing, the line represents the
A)centerline of the pipes.
B)ID of the pipes.
C)OD of the pipes.
D)outline of the piping system.
4.
The two basic types of pipe drawing projections are orthographic and
A)dimetric.
B)trimetric.
C)isometric.
D)oblique.
5.

B)bottom view.
C)top elevation.
D)plan view.
6.
Permanent connections to fittings, auxiliary equipment, and in-line components can be shown on the pipe as
A)circles.
B)solid dots.
C)crosses.

B)are too complex to draw in orthographic projection.
C)have a wide variety of fittings.
D)are to be installed in existing structures.
8.
On a single-line pipe drawing, standard fittings are

C)marked with a small circle.
D)generally not shown.
9.
In dimensioning pipe drawings, non-critical pipe lengths are
A)dimensioned with a note.
B)given approximate dimensions.
C)generally not dimensioned.
D)dimensioned only between major mechanical components.
10.
Pipes with bends are dimensioned
A)center to center.
