Metal hose is an important connecting part in engineering technology, which is composed of bellows, net sleeve and joint. Used in various gas and liquid pipeline systems and length, temperature, direction and viewpoint compensation systems, as compensation components, sealing components, connection components and shock absorption components, used in aerospace, petrochemical, mining electronics, machinery, shipbuilding and medical and health, textile and electronics, power construction and other fields. The new national standard for metal hoses is "general skill conditions for corrugated metal hoses".
The metal hose is made of austenitic stainless steel material or according to user requirements. It has excellent flexibility, corrosion resistance, high temperature resistance, high pressure resistance, and can be connected in any direction in the pipeline for temperature compensation, and can absorb vibration, reduce noise, change the direction of medium transportation, eliminate the mechanical displacement between pipelines or between pipelines and equipment, etc. The double flange metal corrugated hose is especially suitable for flexible joints of various pumps and valves, and has displacement and vibration.
History of Corrugated Metal Hose Technology Research. Since the Germans created and produced the world's first corrugated metal hose, after more than one hundred years of development, metal hoses are known for their reliable sealing, pressure resistance and durability. Many functions such as high temperature and low temperature resistance, corrosion resistance and flexibility have been widely used in aviation, aerospace, nuclear energy, shipbuilding and new construction industries and other industrial fields, and have become indispensable components in modern pipeline systems. With the rapid development of modern industry, the use of metal hoses is more and more extensive, and the requirements for metal hoses are also increasing. The research of metal hose technology must be deepened. The development of metal hoses is usually divided into the following stages.
In the beginning, people used animal skins to form tubular structures to meet the needs of production struggle. After a long time, by the end of the 70 century, the Dutch brothers made longitudinally stitched canvas hoses, which were widely used for fire fighting at that time. Later, with the emergence of rubber in the world market and the development of its vulcanization process, hoses and hoses equipped with fabrics such as wire or hemp rope came out. However, some high-temperature media, such as steam and hot air, are used in engineering. Low-temperature media such as liquid hydrogen, liquid oxygen and liquid helium; corrosive media such as gasoline, kerosene, acid, alkali, etc., of course cannot be transported through hoses. Especially under high temperature conditions, its safety and reliability are more difficult to guarantee.
Therefore, people gradually focus on the metal tube, the shape of the metal tube causes corresponding ripples on the inside and outside. In this way, it not only has the same flexibility as a hose: it also has the functions of high temperature resistance, low temperature resistance, aging resistance and corrosion resistance. Thus, the metal bellows as the main body of the metal hose takes place.
