The flexible metal hose serves as an important component in the modern industrial equipment with the specification from 3mm to 150mm. Besides, the flexible metal hose has a wide application, it is mainly used as wire and cable protection tube of wires, cables and automated instrumentation as well as the civil shower hoses. Generally speaking, the flexible metal hose is made of cooper, stainless steel and iron. In this paper, the author would like to make a brief introduction to the development history of flexible metal hose.
Initially, people use the animal skin to attach into a tubular structure in order to meet the war requirements. At the end of 17 century, Wan Delgkin Brothers made the longitudinally stitched canvas hose, which has a wide application in the fire fighting area. Later, with the development of vulcanization process and appearance of rubber in the international market, rubber tube and fabric equipment wrapped in wire and twine came into birth.

However, it is impossible for rubber tube to transfer the medium with high temperature. Therefore, people gradually attach great importance to the metal tube, so as to change the shape of it to make the corresponding ripples on surface. In this way, it not only as flexible as rubber, but also it boasts such functions as high temperature resistance, old-aging resistance, low-temperature resistance and corrosion resistance.
In 1855, Germany is the first country to publish the patent to manufacture flexible metal hose by using the principle of jewelry manufacture. 30 years later, the E·Levavas seur in France and H·Witzenmann in Germany work together to manufacture the new type of flexible metal bellows, which gain the patent in both France and Germany in August, 1855. Such kind of flexible metal hose has been greatly improved in structure in 1894. This kind of hose is benefits to the sealing of inner side. People use two metal strips to twine in different opposite direction. Therefore,the metal strip is capable of maintaining a balance under the normal force so as to conquer its disadvantages.

In 1929, the flexible metal hose has undergone another technological revolution, which completely solve the uneven change of groove. In this way, the prospect of flexible metal hose is much brighter.
From 1950s, the triple-layer, multi-layer and single layer metal flexible hose, especially the stainless steel flexible metal hose with thin layer, develops even faster. In order to meet the application requirement, people use several measures to manufacture the flexible metal hose. The measures include welding, electroforming,machining, hydraulic and mechanical spinning.
Nowadays, with the development of technology, the flexible metal hose is more suitable than before, and it is also capable of suiting the actual need. Therefore, the flexible metal hose has a wide application in our daily life.
