The work begins with an exhaustive list of professional institutes
related to the topic of piping systems and processes. Examples
of the governing institutes are:

o American Gas Institute
o American Petroleum Institute
o American Society of Testing / Materials and a host of others

There are codes for piping systems, allowable materials,
stresses, seismic loads, thermal heat expansion, fabrication,
installations and testing.

The topic of corrosion is discussed extensively. Corrosion
resistance is the ability of the pipe to resist internal
corrosive effects of fluid flow throughout , as well as external
corrosive flows on the pipe itself .

i.e. soils and the surrounding atmospheric conditions
Corrosion can be reduced or eliminated with suitable coatings,
linings and cathodic protection .

Cathodic protection has become a widely used method for
controlling the corrosion deterioration of metallic structures
in contact with most forms of electrolytically conducting
environments. Cathodic protection reduces the corrosion
rate of a metallic structure by reducing its corrosion potential,
bringing the metal closer to an immune state.

General corrosion describes pipe dissolution over the entire
exposed surface where localized corrosion resides in a small
area of the pipe. Corrosive cracking is the
physical deterioration and cracking of pipe wall due to
increased operating temperature, tensile stress on the pipe
and chemicals. The author describes water impurities like turbidity
(insolubles) , bacteria and viruses.

Tensile stress occurs when a material undergoes a pulling or
stretching force. Stress is defined as a force applied
over a cross-sectional area in typical units of pounds per square inch
(psi) or Newtons per square meter.
The type of stress that a material is exposed to will depend on how
the force is being applied. The three basic types of stress are
tensile, compressive, and shear.

The maximum tensile stress that a material can withstand before
failure is known as tensile strength .
The value of ultimate tensile strength varies widely for
different materials. Soft, malleable materials like
many plastics, rubber, and metals are considered elastic and
will undergo significant deformation before
a complete failure occurs. Hard and brittle materials,
like concrete and glass, have little or no deformation before
complete failure. The ultimate tensile strength for many
different types of concrete, plastics, metal,
wood, glass, rubber and ceramics is fairly described in manuals;
such as this one.

Double wall piping involves the installation of outer pipe
around an inner pipe which prevents the release of hazardous
liquids being transported in the inner pipe.
Typical valve design considerations are temperature, pressure,
shutoff valve operation, pressure drops, corrosive resistance,
velocity, fire safety and hazardous materials.

Generally, no machine should be designed without the ability to
shut it down by some means either electrical, mechanical
or otherwise. In addition, some applications are
constructed with redundant and tridundant capabilities to
address contingency modes.

There is an extensive section on insulation which includes
fiberglass, cellular glass,expanded plastic foam,
foamed plastic, calcium silicate, mineral fiber and
insulating cement.

Overall, the volume enunciates a fairly complete rendition
of applicable fluid principles and materials science
structure of matter intertwined with the relevant
standards setting authorities who promulgate standards
for the engineering and allied professions . This acquisition
would be perfect for the engineering professional in your
household. Students of engineering fluid mechanics
will find this volume useful for exams and projects.
