The bellows has a greater cost advantage than the coiled fusion pipe, and the production efficiency is higher than that of the coiled pipe. Although the double-walled wave tube has the characteristics of large equipment investment, it can reduce the depreciation cost of the equipment by using recycled materials. That is, the inner layer is made of raw materials to ensure the sealing property, and the outer layer is made of recycled materials to reduce the cost. Due to the wide application of pneumatic and electric unit combination meters, bellows type elastic elements have entered a large number of production and use stages. The 60-70s were the development period of instrument elastic components. With the large number of applications of instrumentation and control systems, the demand for elastic components of bellows and diaphragm capsules increased. Although the production of bellows in the former Soviet Union is about several million per year, there are nearly 30 corrugated pipe production plants in the United States.

   With the continuous development of the industry and the promotion of stainless steel bellows in the current industrial chain, the development of the bellows has undergone a long period of time, and it was not until the end of the 17th century that such fittings were actually used. Therefore, reception plays a very large role in the hose and is highly regarded and concerned. Therefore, the rubber has gradually developed and gradually developed. At first, people used animal skin as a material to make a tubular body, but if it encounters high temperature, its firmness is difficult to guarantee. Therefore, in order to improve the gradual concentration of the metal bellows, the corrugated pipe is improved after a long period of improvement and research, and the corrugation and geometry are formed on the surface to be as flexible as the rubber tube.

   The development of bellows means the development of metal hoses. People coat the outer surface of the bellows with rubber, plastic or nylon, and wrap a mesh sleeve made of metal wire or metal strip to change various joint forms. Various forms of metal hoses have been created to accommodate the different requirements of various conditions of use. The appearance of the metal bellows was related to the train, because a gauge was needed at the time, so corrugated plates appeared. From then on, the bellows gradually evolved into many different shapes. In the world of the world war, it was in the military and other fields. Widely used. Until the 20th century, the development of compensators was relatively perfect. Following the US EJMA's standard for axial stainless steel bellows, scientists have tried to develop other uses of stainless steel bellows because of their appearance in various fields. .

   With increased environmental awareness, rising labor costs, and increased construction requirements, countries such as the United States and Canada have expanded their applications of steel bellows to cover almost all areas where concrete and ordinary steel sheets were used as construction materials, including : Roads, railways and mine tunnels, rivers, sewage, drainage ditches and pipelines, underground foundation protection, rainwater, oil and other liquid storage tanks or wells, solid warehouses, simple warehouses and workshops. It is particularly noteworthy that in the face of urban flooding caused by heavy rains, the US solution is to adopt an underground rainwater collection and release system built from CSP materials. Such systems have been widely promoted in the United States as auxiliary systems for commercial, public and civil buildings and road facilities such as parking lots, parks, stadiums, embankments, rainwater siltation belts, floodplains, drains, and depressions.
