I′ron-pipe.

Welded iron tubes are made of skelps bent to a circular form, heated to a welding heat in an appropriate furnace, and then drawn on a drawbench through a pair of jaws with bell mouths. The mouths are opened to receive the end of the skelp, and then closed. The tube is drawn without a mandrel. The sizes are from —

6 inches internal diameter, 1/8 to 3/8 inch thick.

1/4 inch internal diameter, 1/10 inch bore.

For cast-iron water-pipes the working tension may be 1/6 of the bursting tension, say, —

Bursting tension	16,500 pounds.
Proof tension	5,500 pounds.
Working tension	2,750 pounds.

The working tension of cast-iron steam-pipes should be 1/8 only of the ultimate tension.
