On this line two six-inch pipes are laid the entire length, and a third
six-inch pipe runs between Wellsville and Cameron, and about half way
between each of the other stations, "looped" around them. The pipe used
for the transportation of oil is especially manufactured to withstand
the great strain to which it will be subjected, the most of it being
made by the Chester Pipe and Tube Works, of Chester, Pa., the Allison
Manufacturing Co., of Philadelphia and the Penna. Tube Works, of
Pittsburg, Pa. It is a lap-welded, wrought-iron pipe of superior
material, and made with exceeding care and thoroughly tested at the
works. The pipe is made in lengths of 18 feet, and these pieces are
connected by threaded ends and extra strong sleeves. The pipe-thread and
sleeves used on the ordinary steam and water pipe are not strong enough
for the duty demanded of the oil-pipe. The socket for a 4-inch steam
or water pipe is from 21/2 to to 23/4 inches long, and is tapped with 8
standard threads to the inch, straight or parallel to the axis of the
pipe; with this straight tap only three or four threads come in contact
with the socket threads, or in any way assist in holding the pipes
together. In the oil-pipe, the pipe ends and sockets are cut on a taper
of 3/4 inch to 1 foot, for a 4-inch pipe, and the socket used is thicker
than the steam and water socket, is 33/4 inches long, and has entrance for
1 5/8 inches of thread on each pipe end tapped with 9 standard threads
to the inch. In this taper socket you have iron to iron the whole length
of the thread, and the joint is perfect and equal by test to the full
strength of the pipe. Up to 1877 the largest pipe used on the oil lines
