What are the main uses of metal hoses
The term 'metal hose' is no longer unfamiliar in people's daily lives, especially in the pursuit of high-quality life, new technology, and exclusive customization.
Friends who have not met before can also literally understand the general meaning of this type of hose. The inner layer is made of metal material, and the outer layer is covered with a plastic or steel wire woven mesh sleeve. If it is plastic, it is generally made of PE or PVC raw materials. If it is a steel wire mesh sleeve, it is mostly used for shock resistance and compression resistance.
It has many advantages and is widely used.
1： Moisture proof and insulation
Metal hoses are widely used in various fields, especially in wet and cold conditions, with strong ultraviolet radiation, and connecting to certain gases. Therefore, it is necessary to have moisture-proof and insulating properties.
2： High temperature resistance and fire resistance
Many routes do not operate in general natural environments, especially in southern China. During the summer, there is generally high temperature weather in China, and metal hoses have the characteristics of heat resistance and fire resistance to ensure safety.
3： Low temperature and corrosion resistance
It not only has the same flexibility as the rubber hose, but also has high temperature resistance, low temperature resistance, aging resistance, and corrosion resistance.
We cover the outer surface of the corrugated pipe with materials such as rubber, plastic, or nylon, and armor it with a mesh sleeve composed of metal wire or metal tape, transforming various joint forms to create various forms of metal hoses to meet different requirements under various usage conditions.
Joint
The function of the joint is first to connect the mesh sleeve and corrugated pipe as a whole, and at the same time, the joint is a component that connects the metal hose to the metal hose or other pipe fittings and equipment. It ensures that the medium works normally in the Plumbing.

The material of the joint is usually the same as that of the corrugated pipe and mesh sleeve, mainly made of stainless steel. In order to reduce production costs, some metal hoses with larger diameters can be made of carbon steel when transporting medium with low or no corrosiveness; For the joints of metal hoses working in corrosive media, if corresponding measures are taken in design to avoid contact with the medium, carbon steel can also be used for production.
1. Thread type: After tightening the thread, the inner and outer taper surfaces on the two joints closely match to achieve sealing. This structure is easy to operate and has good sealing performance.
2. Flange type: Metal hoses are connected using a flange type connection under normal working pressure. This structure has good sealing performance, but it is difficult to process and the sealing surface is prone to damage. In special situations where quick release is required, the holes through which the fastening bolts pass can be cut open to make a quick release flange.
3. Fast type: Under conditions that require fast loading and unloading, fast type is generally used. It is commonly sealed with an "O" shaped sealing ring made of fluoroplastic or special rubber, and this structure is most suitable for fires, war fields, and other situations where quick loading and unloading are necessary. Within a few seconds, a set of connectors can be docked or disassembled without the need for any special tools.
