A Flexible Metal Hose

A FLEXIBLE metal hose is made at Pforzheim, Germany, by rolling up a metal band like a screw thread, the joints being made tight by a cord of rubber on asbestos. The material is galvanized steel or phosphor-bronze. The hose is very flexible. Its tendency to untwist when roughly handled is overcome by making it double, with opposite windings. It is intended for mining purposes, is eight inches in diameter and will stand a pressure of 200 atmospheres.
