Metal hose structure
The metal hose is composed of corrugated pipe, net sleeve and joint, and the main body is corrugated pipe. Bellows have good flexibility. Due to the low longitudinal stiffness and bending stiffness, bellows can bend smoothly at rated value.
Working within the radius, the mesh sleeve (steel mesh sleeve or steel wire mesh sleeve) plays a reinforcing role and is the "skeleton" of the metal hose, which can be one, two or three layers according to the diameter and pressure of the hose. Mesh sleeve is the main pressure-bearing part of metal hose, which makes metal? The hose has a certain bearing capacity and also plays a role in protecting the bellows. As the bellows is made of stainless steel, it has good corrosion resistance and temperature stability. Metal hose has the advantages of light weight, high pressure resistance, high and low temperature resistance, corrosion resistance and high flexibility, so it has the characteristics of vibration resistance, bending resistance, displacement compensation and stress absorption.
Five elements of metal hose modeling:
1、? Size? Nominal diameter of hose, joint type and size, hose length.
2. Stress? Actual working pressure and nominal pressure PN/? Working pressure p.
3. medium? According to the corrosion resistance table, the chemical properties of the conveying medium in the hose determine the materials of each part of the hose.
4. temperature? Working temperature and range of the medium in the hose; Ambient temperature when the hose works. At high temperature, the maximum allowable pressure at working temperature must be determined according to the temperature correction coefficient, so as to determine the correct pressure grade.
5. Status? According to the situation of the hose in use, refer to the correct installation mode of the hose, the length calculation of the hose in various motion States, the minimum bending radius of the hose, and the correct selection and installation parameters.
China is a big producer and exporter of metal hoses. Most of the metal hoses sold in the world are produced and exported from China, and China has become the main supplier of metal hoses in the world. Although the metal hose industry in China is huge, due to the weak technical innovation ability,
Due to the single market structure and weak brand influence, many metal hose manufacturers often lack core competitiveness and are difficult to become bigger and stronger.
The sales volume of stainless steel hoses is 65.438+0.45 billion yuan, of which the proportion of threaded stainless steel hoses is less than 25%, which is not only far from the product structure of hoses in the international market, but also unable to meet the growing demand of stainless steel hoses in domestic manufacturing industry.
