Air Hose Pipe Soft, Repetitive Bending, Good Flexibility
Air Hose Pipe is an important part in modern industry. Air Hose Pipe is mainly used as wire, cable, automatic instrumentation signal cable protection pipe and civil shower Air Hose Pipe, specifications from 3mm to 150mm. Small caliber Air Hose Pipe (inner diameter 3mm-25mm) is mainly used for the sensor line protection of precision optical ruler and industrial sensor line protection.
Most of the metal Air Hose Pipe is made of stainless steel. So in terms of flexibility and anti-corrosion is better than other pipelines. However, different media not only use the rotating joint is not the same, in the Air Hose Pipe configuration is not the same. Especially the length of the metal Air Hose Pipe. To be configured according to different swivel connectors. Too long will cause inconvenience and waste of resources, too short will cause the flexible Air Hose Pipe is not enough to play the role of metal Air Hose Pipe.
The Q-type rotary joint must be equipped with a Air Hose Pipe. Because the Q-type sealing structure needs to automatically adjust the concentricity and automatic compensation pressure to ensure the sealing surface of the laminating. So the Air Hose Pipe provided with the Q-type swivel joint will take into account the free swinging of the swivel joint. In particular, heat conduction oil rotary joint, must use long enough metal Air Hose Pipe. Ensure that the metal Air Hose Pipe has enough space to keep the weld area from force. The following is specific about the need to configure the rotary joint Air Hose Pipe Several points:
The normal configuration of the Air Hose Pipe length is 500mm. two inches. Swivel joint configuration Air Hose Pipe as long as enough to rotate the joint activity is good. More than two inches of choice is called configuration Air Hose Pipe to take into account the flexibility of the Air Hose Pipe is not enough, so to special lengthened 20mm-50mm. Air Hose Pipe can be bent to 180 °.
Type choice of Air Hose Pipe: best use annular wave Air Hose Pipe. If you use a helical wave Air Hose Pipe It is best to use it an inch and a half. At the same time to make the Air Hose Pipe can be arbitrarily curved into 180 °.
Air Hose Pipe Seal knot: The most stable or with taper transition joint. In the early stage, the sealing form of the flat head and gasket has been changed to the taper with spherical seal structure.
Air Hose Pipe bearing Capacity: The Rotary joint configuration Air Hose Pipe can be resistant to 1.0MPA is good; the Air Hose Pipe should be resistant to 1.5Mpa; heat-conducting oil rotary joint configuration Air Hose Pipe preferably using a slightly higher pressure Air Hose Pipe. It is recommended to use a double net sleeve Air Hose Pipe. and the external Air Hose Pipe with fire insulation materials wrapped. One is to be able to heat preservation, the second can play a protective role.
Air Hose Pipe features double buckle stainless steel Air Hose Pipe
1, the pitch between flexible.
2. Good scalability, no obstruction and stiffness.
3. Light weight and good caliber consistency.
4, flexibility, repetitive bending, good flexibility.
5, corrosion-resistant, high temperature resistance is good.
6, anti-rodent bite, good wear resistance, to prevent internal wire wear.
7, bending resistance, tensile properties, strong resistance to lateral pressure.
8, soft and smooth, easy to thread installation positioning.
Corrosion causes the reaction of and oxygen in the atmosphere to form an oxide film on the surface. The iron oxides formed on ordinary carbon steel continue to oxidize, which causes the corrosion to expand and eventually form holes. You can use paint or oxidation-resistant (e.g., zinc, nickel, and chromium) to insure the surface of the carbon steel, but, as people know, this protection is only a thin film. If the protective layer is damaged, the steel below begins to rust.
The corrosion resistance of stainless steel Air Hose Pipe depends on the content of chromium, when the amount of chromium added to 10. At 5%, the corrosion resistance of steel increased significantly, but the chromium content was higher, although the corrosion resistance could still be improved, but not obvious. The reason is that when the steel is alloyed with chromium, the type of surface oxide is changed into a surface oxide similar to that formed on the pure chromium. This tightly bonded rich chromium oxide protects the surface and prevents further oxidation. This oxide layer is very thin, through it can see the natural luster of stainless steel surface, make stainless steel has unique surface. Moreover, if the surface is damaged, the exposed steel surface will be repaired with the atmospheric reaction, and the "passivation film" can be formed again, and the protective effect will continue.
