Corrugated metal hose is generally composed of three parts: corrugated pipe, net sleeve and joint. The corrugated pipe is the body of the metal hose, which plays a flexible role; the mesh sleeve plays a role of strengthening and shielding; the joint plays a role of connection. For different usage requirements, they are connected in different ways: the bellows, the mesh sleeve and the joint are connected in the form of welding, called welding; connected in the form of mechanical clamping, called mechanical clamping; In addition, there is a combination of the above two methods, called hybrid.

Net cover: The net cover is woven by a certain number of intersecting strands of metal wires or a number of frayed metal bands in a certain order, and is sheathed on the outer surface of the metal corrugated pipe at a specified angle, which plays a role of strengthening and shielding. The mesh sleeve not only shares the static load of the metal hose in the axial and radial directions, but also ensures the safe and reliable operation of the metal hose under the condition that the fluid flows along the pipeline and generates pulsation. At the same time, it can also ensure that the corrugated part of the hose is not directly The ground is mechanically damaged by relative friction and impact. The strength of the corrugated pipe woven with the mesh sleeve can be increased from ten to ten times. The highest shielding capacity can reach 99.95%.

The material of the mesh sleeve is generally the same as that of the corrugated pipe, and there are also two kinds of materials used in combination. Ordinary metal hoses only use one layer of netting; for special applications, there are also two-layer and three-layer braiding. Depending on the diameter of the corrugated pipe and the requirements for use, it is often made of wire with a diameter of 0.3 to 0.8 mm or a strip with a thickness of 0.2 to 0.5 mm. 4 to 15 wires per share, one strip per spindle. Most of the steel mesh sleeves produced are 24 strands, 36 strands, 48 ​​strands, 64 strands, extra large diameter corrugated pipes, and 96 strands, 120 strands and 144 strands.

In addition to the number of strands (wire), wire diameter, number of spindles (belt), and thickness, the main weaving parameters of the net cover include coverage area, weaving distance, weaving angle, etc. They are all important basis for determining the performance of metal hoses.
