A test of the superiority of this method of moving, and controlling
long columns of fluids under extreme heavy pressures was made at the
time of the introduction of long pipe lines _for conveying oil from the
wells to the seaboard_.
NOTE.—After trying various kinds of pumps for forcing the oil through
these long pipes, and after having a succession of disasters in the
way of burst pipes, and leaking joints, it was decided to test the
efficiency of the direct-acting duplex steam pump. These pumps were
placed in the various stations along the pipe lines, and after a
continued service of many years, have shown their perfect adaptation
to that exceptionally hard service. These pumps convey the oil over
mountains where at times the coupled lines have been over one hundred
miles long between the pumps, and where the pressure on the plunger
of the pump sometimes rises to 1,500 lbs. per square inch.
