Metal Hose fittings are a high quality flexible pipe in modern industrial piping. It consists mainly of bellows, mesh sleeves and joints. Its inner tube is a thin-walled stainless steel bellows with a spiral or ring shape, and the outer sleeve of the bellows is woven by stainless steel wire or steel strip according to certain parameters. The joints or flanges at the ends of the hose are matched to the fittings or flanges of the customer's piping. The hose's bellows are formed by extremely thin-walled seamless or welded stainless steel tubes that are highly plastically machined. Due to the elastic properties of the bellows profile, the hose has good softness and fatigue resistance, making it easy to absorb cyclic loads of various motion deformations, especially in the pipeline system. Media visualization (visual), process automation.
The metal Hose fitting consists of a metal pipe body, a stainless steel wire mesh sleeve and a joint piece. In the ship pipeline system, it is mainly used in the connection between the pipeline and the equipment whose pipeline medium is oil or fresh water, which can compensate a certain relative displacement and play the role of vibration and noise reduction. However, if the selection is not appropriate, not only will it not have the effect of vibration isolation and noise reduction, but it will cause problems such as pipeline leakage or equipment failure due to damage of the metal hose.
The selection of metal hoses mainly includes the correct selection of parameters such as diameter, connection type, working pressure, temperature correction, minimum bending radius and hose length. The diameter, connection type and working pressure are directly dependent on the piping system requirements. Generally, there is no problem. It is worth mentioning that when selecting the hose design pressure (should be greater than the system working pressure), it should not be too high, because with the soft The bending capacity of the pipe is greatly improved, and its bending ability is greatly reduced. The temperature correction and minimum bend radius are fixed for the product and are given by the manufacturer. The problem we often have is the choice of the length of the metal hose. If the hose is too long, it will cause instability, increase the flow resistance, and additional mechanical damage and vibration problems. If the hose is too short, it may not be compensated or damped. Eliminating noise and other purposes can also cause excessive bending stress and affect life.
