The function of the exhaust metal hose
Metal hose is generally composed of three parts: corrugated pipe, net sleeve and joint. The corrugated pipe is the main body of the metal hose, which plays a flexible role; the net sleeve plays the role of strengthening and shielding; the joint plays the role of connection. For different usage requirements, they are connected in different ways: the bellows, the mesh sleeve and the joint are connected in the form of welding, which is called welding; and the connection is in the form of mechanical clamping, which is called mechanical clamping. In addition, there is a combination of the above two methods, called hybrid.
The production and holding costs of stainless steel corrugated pipes are at a high level, which provides a certain support for this type of pipe fitting industry. The price of stainless steel bellows has gradually increased. These factors have promoted manufacturers to increase the output of stainless steel. Moreover, due to the strong demand in the construction and home appliance industries, the demand for stainless steel bellows in Asia is expected to continue to grow. Experts in the industry pointed out: The central bank's policy has promoted the acceleration of market control, and the industry has become increasingly financial. Funds and inventory have become the two major joints of the stainless steel bellows market trend in the next step. Metal hose is a high-quality flexible pipeline in modern industrial pipelines. It is mainly composed of bellows, net sleeves and joints.
Following people's higher requirements on the appearance, riding safety and comfort of commercial vehicles, car companies began to pay attention to the use of exhaust metal hoses. The article analyzes the functional advantages of the exhaust metal hose and its application in cars. Nowadays, with the strengthening of environmental protection and the introduction of advanced foreign commercial vehicle technology, many domestic commercial vehicle manufacturers have successively adopted bellows to connect exhaust pipes and mufflers. Although the bellows can achieve certain azimuth compensation and vibration reduction effects, it still has limitations in reducing metal fatigue, noise reduction and accepting circumferential shear load and other indicators; therefore, some domestic commercial vehicle manufacturers and developed companies All commercial vehicle manufacturers have adopted flexible metal hoses with inner buckle and structure instead of corrugated pipes. Wire protection tubes for precision optical scales, optical measuring instruments, instruments, machinery and equipment, suitable for public telephones, remote water meters, door magnetic alarms and other equipment that requires safety protection of wires, protection tubes for various small wires, Various computers. Four categories of products applicable to stainless steel metal hoses: armored fiber optic cable robots and other network cable protection pipes.
