Knowledge to know when installing metal hoses

Compared with other types of joints, metal hoses have advantages. For this knowledge, we should understand that there are many ways.That people fight against joints at the moment. Maybe people who we disagree prefer different aspects. Yes, but many people are more interested in the length of time used. Because if the quality of the joint is very bad, then some work will happen frequently, and this will bring trouble to our life. Convenience, therefore, the length of the use time is also very important.So when you choose, you can choose a metal hose.


In the metal hose installation, if the material is deformed under the force. An internal reaction force of equal magnitude but opposite direction will be generated to resist the external force. Such a reaction force is called stress. The editor believes that the stress should be controlled during installation. In complex piping systems, there are often various difficulties in installation due to the limitations of the space and location conditions:The formed pipe cannot be installed; bending, straight, and improvising the installed pipe will inevitably produce partial Cold correction.


Depending on the pipe diameter and the specific conditions of the site. The amount of cold correction ranges from a few millimeters to tens of millimeters. And some up to hundreds of millimeters. Practice has proved that the larger the amount, the higher the internal stress. These residual installation stresses in the pipeline system are undoubtedly a great hidden danger. Which will cause problems such as metal hose breakage and affect the safety of the pipeline.

The metal hose is the primary pressure-bearing part of the hose installed in the pressure pipeline. It also acts as a sheath for the bellows. According to the pressure in the pipeline and the application place, one or more layers of stainless steel wire or steel can be selected. The belt is woven, and the pressure die of the metal hose is usually PN0.6-32.0Mpa. The highest is 42.0MPa.


Because the material for the main parts of the hose is to use austenitic stainless steel, it ensures the excellent temperature resistance and corrosion resistance of the hose. At the same time. The working temperature of the hose is extremely wide, ranging from -196 to 600 degrees. The pipe selects the applicable stainless steel trademark according to the corrosiveness of the medium passing through the pipe to ensure the corrosion resistance of the hose.


Metal hoses has outstanding flexibility, fatigue resistance, high pressure resistance, high and low temperature resistance, corrosion resistance and many other characteristics. Compared with other hoses (rubber and plastic hoses), the life span is much higher. So it It also has higher generalized economic benefits.
