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.
