Continuous stave pipe has greater
carrying capacity than any other kind
of pipe. 1t has been proved by ex-
reriments that smooth planed wooden
surfaces offer the least resistance to,
the flow of water.
Light steel Riveted Pipe.

been coated with asphaltnm or similar
conting.
Light steel pipe, from l2 TO 18 guage,
has been In use twenty to thirty years
and when taken up were found to be
in fairly good condition and were again
used. In other instances, light steel
pipes have failed entirely in from two
to five years The life of the light
steel pipe would depend. chiefly. upon
the character OF the soil in which Il

ence has not shown the existence of
deleterious substances In the oil in
this vicinity. The use of light iiveied
steel pipe seems to have hesn CON
fined chiefly to power plants. snicine
operations and irrigation works.
The use OF slip joints on this kind
of pipe would not be advisable under
the pressures proposed TO be used

moisture and corrosive salts i'm the
soil. 1t would withstand the pressure
required. but as II would not fail by
the corrosion of entire sections but
by the rusting through OF small holes
the absence of the coating on n small
part of the pipe would leave II open
TO the action of moisture and conse
quent failure.
Lap Welded steel Pipe.

several places visited for periods vary

was kalamined pipe. 1t did not show
any of the asphaltum coating and some
corrosion of the surface had taken
place. The kalsomining consists of
Incorporating on and into the metal
of the pipe a non-corrosive metal and
increases the cost of the pipe consld-
erably The only advantage in the
use of lap welded steel pipe over the
light riveted steel pipe would be the
Increased thickness of the shell, re-
quiring a longer period of time to rust
through The cost of laying this pipe
would be greater than for the light
pipe owing to Its greater weight and
the greater cost of the lead joints. |
