Metal hoses occupy an important position in modern industry, in the late 17th century in the Netherlands The Delgajin brothers made longitudinally stitched canvas hoses, which were widely used in firefighting operations at the time. Later, with the emergence of rubber in the international market and the development of its vulcanization industry, rubber hoses and hoses armored with fabrics such as metal wire or hemp rope emerged. However, some high-temperature media such as steam and hot air in engineering; Low temperature media such as liquid hydrogen, liquid oxygen, and liquid helium; Corrosive media such as gasoline, kerosene, acid, and alkali cannot be transported using rubber hoses. Especially under high temperature conditions, its safety and reliability are even more difficult to ensure.
Therefore, people gradually focused their attention on the metal tube, changing the geometric shape of the metal tube to produce corresponding ripples on its inner and outer surfaces. In this way, it has the same flexibility as a rubber hose; At the same time, it also has high temperature resistance, low temperature resistance, aging resistance, and corrosion resistance. So, the metal corrugated pipe, which serves as the body of the metal hose, was produced in this way.
The large-scale production and use of metal hoses in China began in the late 1980s. Due to outdated welding technology, the country can only prioritize the development of seamless ultra-thin wall pipe industry. Using ultra-thin wall pipes as raw materials, corrugated pipes can be processed through two methods: mechanical forming and hydraulic forming. The development of seamless and ultra-thin wall pipes has driven the development of metal hoses, especially high-pressure gas pipes.
In the early 21st century, with the development of automatic argon arc welding and laser welding technology in China, the technology of welding sheet metal into pipes and processing them into corrugated pipes has been effectively developed. Due to limitations in welding technology, the initial use of slotted corrugated pipes was limited to low-pressure pipelines. With the effective improvement of welding technology in the later stage, especially the introduction of technology from Japan, Europe and America, the development of seamless metal hoses has been rapid, surpassing seamless metal hoses in terms of quality, price and production efficiency.
