APPENDIX B
PIPE SIZE DATA
Pipe sizes can be confusing because the terminology
may relate to historical dimensions that are loosely
related to actual dimensions. Early on, pipe was sized
by inside diameter. This practice was abandoned to
improve compatibility with pipe fittings that must
usually fit the outside diameter of the pipe, but it has
had a lasting impact on modern standards around the
world. Presently, the pipe size designation generally
includes two numbers: one that indicates the outside
diameter or nominal diameter and another that identifies the wall thickness.
Historically, only a small selection of pipe wall thickness was in use: standard weight (Std), extra strong
(XS), and double extra strong (XXS), based on the iron
pipe size system of the day. In 1927, the American Standards Association created a system of schedule numbers
that designated steel pipe wall thickness based on
smaller steps between sizes. In the mid-twentieth
century, stainless steel pipe—which permitted the use of
thinner walls with much less risk of failure due to corrosion—came into more common use. Consequently,
schedules 5S and 10S were created in 1949, and other
“S” sizes followed.
Pipe is specified by its nominal inside diameter
through 12 in and smaller. In this range, nominal size
refers to the approximate inside diameter of a schedule
40 (or standard weight) pipe. Pipe 14 in and larger is
specified by the actual outside diameter. For a given
pipe size, the outside diameter is the same for all weights
and schedules. In North America, pipe size is specified
by Nominal Pipe Size (NPS) and is based on inches. The
European version is called Diametre Nominal (DN)
and is based on millimeters. Japan has its own set of
standard pipe sizes, called Japanese Industrial Standards
(JIS) pipe, that are based on millimeters.
Many different standards exist for pipe manufacture,
including American Petroleum Institute (API) 5 L,
American National Standards Institute (ANSI)/American
Society of Mechanical Engineers (ASME) B32.10M and
B36.19M in the United States, and British Standard
(BS) 1600 and BS European Standard (EN) 10255 in
the United Kingdom and Europe. Manufacturing standards
commonly require a test of chemical composition and
a series of test of chemical composition and a series of
mechanical strength tests for each heat of pipe.
Pipe is made of a wide variety of materials including
ceramic, fiberglass, metals, concrete, and plastic. Metallic
pipes are commonly made of steel or iron, such as carbon
steel, stainless steel, galvanized steel, cast iron, and
ductile iron. Inconel, chrome moly, and titanium alloys
are used in high temperature and pressure applications.
Copper and aluminum pipe are frequently employed.
The following NPS and DN table gives selected data
for commercial pipe.
