Metal hose is widely known as metal flexible hose, is a versatile and durable pipe product used to transport liquids and gases. Usually made of stainless steel, it is known for its strength, corrosion resistance and flexibility, stainless steel hose can bend and move without cracking or breaking. Metal flexible hoses are widely used in petroleum, chemical, metallurgy, aerospace and other fields, especially in working conditions that need to withstand high pressure and mechanical shock.
Annular Corrugated Metal Hose
Corrugated metal hose is a common metal hose with many characteristics such as good flexibility, fatigue resistance, high pressure bearing, good temperature resistance, corrosion resistance, strong sealing, etc. It has a much longer life than other hoses (rubber hoses, plastic hoses). It is widely used in chemical, steel, electric power, construction, medicine, food, transportation and other industries.
Metal Braided Flexible Hose
Metal braided hose usually refers to stainless steel braided hose, which is a flexible connection element composed of corrugated metal hose and stainless steel braided mesh layer. It can operate stably under extreme conditions of high pressure, high temperature, strong corrosion and strong vibration, and is an important flexible connection part in industrial pipelines.
Galvanized Metal Flexible Hose
Galvanized metal hose is a flexible metal pipe made of galvanized steel strip rolled into a spiral shape. It has good bending and compression resistance and is often used in cable protection, wire threading and light mechanical connection. Its surface is galvanized to effectively prevent corrosion and rust, and is suitable for use in dry or semi-humid environments.
Metal hoses usually consist of the following parts:
Core: Made of spirally wound stainless steel, this is the main conduit for the transported media (liquid/gas).
Braid: There are one or more layers of braid surrounding the core. The braid is usually stainless steel and gives the hose strength and flexibility. The number of braids usually determines the pressure capacity of the hose.
End fittings: Depending on the application, a variety of end fittings can be connected, such as flanges, threaded connectors or quick connectors.

FAQS
What are the different types of metal flexible hoses?
According to the structure, it can be divided into corrugated stainless steel hose and braided stainless steel hose. According to the material, it can be divided into 304 stainless steel hose, 316 stainless steel hose, 316L stainless steel hose.
How long do metal hoses last?
The life of the flexible metal hose is affected by working pressure, temperature, medium, frequency, environment, etc. For general industrial use (non-high pressure vibration), the metal hose can be used for up to 8 years. If high-quality materials (such as 316L stainless steel) are used, the life is usually more than 10 years.
What are the cons of stainless steel hose?
Large bending radius, heavy weight, high price, poor shock absorption effect
Are metal hoses better?
Stainless steel hoses are excellent in pressure resistance, explosion resistance, fire retardancy, moisture resistance, high temperature resistance, and long service life, but they are higher in cost and weight than rubber hoses and plastic hoses, and conductivity is also worth considering. You can choose a hose according to the usage.
