Will take place on the outer area.
In the case of wire. galvanizing has
been esta blished and in the case Of
the bands. a special a%sphalting dip
has been developed as q means OF
preventing the deterioration Of h
metal itself. When considered from
the actual strength basis. therefore.
we can reasonably expect that wood
pipe would stand up and serve its
purpose ever though seventy-five per-
cent Of the metal on the bands or
wire had been removed by ~corrOsion
or other outside causes.
That we may reasonably expect a
greater length Of life from the bands
than from metal pipe designed for
the same purpose can readily be
seen when we take into consideration
the thickness OF the shell in the
metal pipe compared with the steel
wire or bands on the wood pipe. The
shell of the metal pipe is probably
less than one-half as thick as h
wire or band used on the wood pipe.
designed to operate under an equal
pressure. Hence Sthe distance
through which corrosion in metal
pipe must penetrate is less than half
as great Is the thickness Of the wire
or band. 1t would therefore appear
that the life of the bands or wire on
wood pipe would be twice as great
as the life of the metal pipe, other
things being equal. That this Is the
actual result is obvious. In fact.
properly protected bands will last in
definitely.
Economy Considered
Mr.. Ledoux in his paper says that
tho ouaro 90 dispha rpa 1apacitv Of
wood pipe is probably 20 per cent
greater than that of cast IRON and
the same is probably true OF its car
rying capacity in comparison with all
other materials. With metal, tuberc-
ulation rapidly takes place. Other
materials scale and cause increase OF
friction and accumulation Of accre-
tions. Wood remains smooth. Wood
is easily laid, safely and economical
ly tapped and adapted to fitting to
any connection. 1t is not affected
by electrolysis. Does not burst on
freezing. Is non-corrosive and sani-
tary to the highest degree.
! All of these considerations make
for economy. CreOsoted wood pipe
made in this new era of wood pipe
construction is commanding the at
tention of communities which are
constructing waterworks systems be
cause Of the money which may be
saved to those communities by its
use. In this day when taxation bur
dens the people, public administrat-
ors are searching for sound econ
omies in building public works and
are not overlooking a type Of con-
struction which can be built at SO
much less cast than other competing
materials and designs that the mere
interest on the difference in the cost
IL accumulated would forever re-
build and maintain the system. This
fact can be easily demonstrated in
the case Of creosoted wood pipe.
And so 1t is that the great for
ests of our Western Coast with thei
huge trees which have been for CEN
turtles in the process Of growth con-
tinue to render increasing service to
humanity. While man, through the
aid Of chemistry. adds life to the
fibre of the wood and makes 1t i'm
mune from the attacks of destroying
fungus rot and then through his
mechanical genius further completes
the purposes OF nature by adapting
the wood to the uses OF mankind.
