2, the metal hose has good flexibility, no blockage and good rigidity;
3. The metal hose has light weight and good caliber consistency;
4. The metal hose has good flexibility, repeated bending and flexibility;
5. The metal hose has good corrosion resistance and high temperature resistance;
6. The metal hose is resistant to rat bite and abrasion, and the internal wires are prevented from abrasion;
7. Metal hose has strong bending, tensile and lateral pressure resistance;
8. The metal hose is soft and smooth, easy to thread, install and locate;
Application of metal hose products: used as signal wire, transmission wire and cable and optical cable protection of various equipment.
1. Wire protection tubes for armored optical cables, precision optical rulers, optical measuring instruments, medical instruments and mechanical equipment;
2. Suitable for public telephones, remote water meters, door magnetic alarms and other devices that need to protect the wires safely;
3, all kinds of small wire protection tube;
4, all kinds of computers, robots and other network line protection tube.
How to choose metal hose connector;
1. Size: nominal diameter of hose, joint type (mainly flange connection, threaded connection and quick joint connection), size and length of metal hose.
2. Pressure: According to the actual working pressure of the hose, check the nominal diameter and pressure gauge of the corrugated metal hose and decide whether to use the stainless steel mesh metal hose.
3. Medium: The chemical properties of the conveying medium in the hose determine the material of each part of the hose according to the corrosion resistance of the hose material.
4. Temperature: the working temperature and range of the medium in the hose; Ambient temperature when the hose works. At high temperature, the pressure after temperature correction should be determined according to the temperature correction coefficient of the high temperature working pressure of the metal hose, so as to determine the correct pressure grade.
5. State: According to the state of the hose in use, refer to the correct use and installation method of the metal hose, the optimal length of the hose during settlement compensation, the length calculation of the hose in various motion states, the minimum bending times and the minimum bending radius of the hose, and correctly select and install the parameters.
Classification of metal hose structures:
1, type A: one end is an arc joint clamped in the female head, and the other end is a threaded connection with internal thread.
2. Type B: one end is a groove with two male lugs, and the other end is a thread connected by external threads.
3. Type C: one end is a groove with two male pull heads, and the other end is a bamboo-like hose connector.
4.d-type: one end is a groove with two men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women, men and women
5.e-type: one end is an arc joint stuck in the female head, and the other end is a hose joint with a bamboo joint.
6.f-type: one end is an arc joint clamped in the female head, and the other end is a thread with external thread connection.
7.DC type: it is a groove with two pins, which can be clamped into the cap plug of the pin arc.
8.DP type: it is an arc plug, also called internal plug.
9. F-type with flange: one section is an arc joint clamped in the female head, and the other end is a flange connected with the flange.
10, type C with flange: one end is a groove with two lugs, and the other end is a flange connected by flange. As a kind of flexible pressure-resistant pipe fitting, metal hose is installed in liquid conveying system, which compensates the mutual displacement of connecting ends of pipelines or machinery and equipment, absorbs vibration energy, and plays a role in reducing vibration and noise. It has many advantages such as good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance and so on. Elements of metal hose selection: size, nominal diameter of hose, joint type (mainly flange connection, threaded connection and quick joint connection), size and length of metal hose. Pressure According to the actual working pressure of the hose, check the nominal diameter and pressure gauge of the corrugated metal hose and decide whether to use the stainless steel mesh metal hose. The chemical properties of the conveying medium in the medium hose determine the material of each part of the hose according to the corrosion resistance of the hose material. Working temperature and range of medium in temperature hose; Ambient temperature when the hose works. At high temperature, the pressure after temperature correction should be determined according to the temperature correction coefficient of the high temperature working pressure of the metal hose, so as to determine the correct pressure grade. According to the state of the hose in use, refer to the correct use and installation method of the metal hose, the optimal length of the hose during settlement compensation, the length calculation of the hose in various motion states, the minimum bending times and the minimum bending radius of the hose, and correctly select and install the parameters.
