Plastic covered metal hose plays an important part in modern industry. Then how it develops? Next let’s talk about the history of plastic covered metal hose.
Develop history of metal hose
In the old time, people suture the hide to pipe structure to fit the demand of product. Long times after to 17 century, Netherlands brothers create the nylon hose. While it rapidly becomes popular in fire fighting. Later, rubber comes into the stage, then develop rapidly. Because of the rubber, chamber tube and yarn hose appears gradually. However, when transfer corrosive mediums like oils, rubber hose will not work. Especially in high temperature condition, the safety and reliability will be hard to guarantee. Thus, people focus on metal hose. Change the shape of metal hose and make it corrugated. Then it becomes flexible similar with rubber hose. Meanwhile, it is resistant to aging and corrosion.
On such occasion, corrugated hose appears as the body of metal hose. In 1855, Germany published the patent to produce corrugated hose. 30 years later, France and Germany cooperate with each other and develop a new corrugated metal hose. Then get the patent in August 1885. While this hose is a spiral type.
In 1894, such kind of plastic covered hose improved. People twine 2 metal belts in opposite direction. Thus, the metal belt gets balance with the force and overcomes the self stretch problem.
There was another revolution in 1929. While this entirely solve the sealing problem. Since then, the metal hose develops to a broad prospect. People produce the hose with steel and copper alloy. That is seamless or seam hose. It is compressible and flexible. Besides, it has great seal.
Since 1950s, double layer and multi-layer hose develops rapidly. While the size could be 2-500mm.
