The difference between corrugated compensator and metal hose

The difference between corrugated compensator and metal hose
Corrugated compensator and metal hose, are two products widely used in industrial production and mechanical equipment. The role of both products is to solve the problem of vibration, noise, displacement and pressure in the pipeline connection. However, there are still some differences between the corrugated compensator and metal hose.
 
First of all, the corrugated compensator and metal hose in the structure there are obvious differences. The corrugated compensator is composed of bellows, flange and support pieces, and the bellows plays the role of balancing the expansion and vibration of the pipe inside. The metal hose is composed of a number of different materials around the metal band, the shape is similar to the ordinary hose.
Second, the corrugated compensator and metal hose in the use of the scope and performance also has a big difference. Corrugated compensator is mainly used in high temperature, high pressure, high speed, corrosive liquid pipeline and other environments. It can effectively compensate for expansion, contraction, oscillation and displacement in the pipeline to ensure the normal operation of the entire pipeline system. While the metal hose is mainly used in low pressure, room temperature, non-corrosive liquid transmission pipeline, its role is to relieve the vibration and displacement of the pipeline connection.
In addition, corrugated compensator and metal hose in the installation and maintenance there are certain differences. Corrugated compensator flange connection is special, need to weld or bolt connection, and also need to carry out regular inspection and maintenance. The metal hose can use the ordinary flange connection method, installation and maintenance is relatively simple.
Finally, the corrugated compensator and metal hose in the price also has a big difference. Corrugated compensator relative to metal hose, the price is higher, but its service life is longer, more stable performance, more suitable for high pressure, high temperature, high speed, corrosive liquid transmission pipeline use. And metal hose relatively low price, but its service life is relatively short, more suitable for low pressure, low speed, non-corrosive liquid transmission pipeline use. To sum up, although the corrugated compensator and metal hose are designed to solve the vibration, noise, displacement and pressure problems in the pipeline connection, but there are some differences between them in terms of structure, scope of use and performance, installation and maintenance, as well as price. Therefore, when choosing to use pipeline connection products, you need to choose according to the actual situation in order to meet the specific needs of production and mechanical equipment.
