Pipe manufactured from double thick iron is called X-strong pipe, and
pipe made double the thickness of X-strong is known as XX-strong pipe.
Both X-strong and XX-strong pipe are furnished plain ends—no threads,
unless specially ordered.
The table “Data relating to iron pipe” will be found especially useful
to the engineer and steam fitter. The size of pipes referred to in
the table range from 1/8 to 10 inches in diameter. In the successive
columns are given the figures for the following important information:
1. Inside diameter of each size.
2. Outside diameter of each size.
3. External circumference of each size.
4. Length of pipe per square foot of outside surface.
5. Internal area of each size.
6. External area of each size.
7. Length of pipe containing one cubic foot.
8. Weight per foot of length of pipes.
9. Number of threads per inch of screw.
10. Contents in gallons (U. S. measure) per foot.
11. Weight of water per foot of length.

[Footnote A: The Standard U. S. gallon of 231 cubic inches.]
The division of process in the manufacture of pipe, takes place at
1-1/4 inch, 1-1/4 inch and smaller sizes being called butt-welded pipe,
and 1-1/2 inch and larger sizes being known as lap-welded pipe; this
rule holds good for standard, X-strong and XX-strong.
