  The metal hose manufacturers introduce you to the metal hose:

  The metal hose is generally composed of three parts: a bellows, a mesh sleeve and a joint.

  The bellows is the body of the metal hose, which plays the role of flexibility, and the net sleeve plays the role of strengthening and shielding; the joint acts as a connection.

  For different use requirements, the ways of connecting them are different: the bellows, the net sleeve and the joint are connected by welding, called welding type; they are connected by mechanical clamping, called mechanical clamping type. In addition, there are two methods described above, called hybrid.

  Metal hose products include oil suction hoses, steam hoses, sandblasting hoses, acid and alkali hoses, food hoses, oxygen hoses and various special hoses. Widely used in machinery, chemical, petroleum, metallurgy, food and other industries.

  What is the pressure range of the pressure-resistant metal hose: the pressure range of the hose is generally PN0.6 - 32.0Mpa. Up to 42.0MPa.

  The metal hose is the main pressure-bearing part of the hose installed in the pressure pipeline, and at the same time, the bellows is sheathed. According to the pressure in the pipeline and the application place, one or more layers of stainless steel wire or steel strip can be selected. Weaving.

  Metal hose manufacturers teach you several elements of the selection

  1. Liquid temperature, working temperature and range of the medium in the hose, working ambient temperature. At high temperatures, the operating pressure temperature correction factor at the high temperature of the metal hose shall be determined to determine the pressure after the temperature correction to determine the correct pressure rating.

  2, the transmission medium, the chemical properties of the medium transported in the hose, according to the corrosion resistance of the hose material, determine the material of the hose and each part.

  3, the state of the hose, according to the state of the hose when used, refer to the correct use of the metal hose and the installation method and the length of the hose in the settlement compensation. The length of the various movement states of the hose and the small bending of the hose Factors such as the number of times and the small bending radius, the parameters are correctly selected and the length of the hose is correctly installed.

  4, the pressure range, according to the actual working pressure of the hose, then query the nominal diameter and pressure gauge of the corrugated metal hose.

  5, the correct length size and nominal diameter, the choice of joint type (mainly flanged, threaded, quick joint connection) and metal hose size, hose length.
