When it comes to high-temperature metal hose, many people may not know what it is. In fact, this kind of pipe is often seen and used in our daily life. For example, the pipe connecting the water heater and the nozzle in our house belongs to the high-temperature metal hose. So, what are the types of high temperature resistant metal hose? What is corrugated metal hose? Now let's have a simple understanding with Xiaobian.
1、 What are the types of high temperature resistant metal hose
What are the types of high temperature resistant metal hose
1. Threading metal hose
The raw material of this kind of hose is made of stainless steel, which is mainly used as the protective tube of wire and cable. This kind of hose has many advantages, such as excellent flexibility and good corrosion resistance.
2. Corrugated metal hose
This kind of hose is called leather tiger. It has a long life and good sealing. It is widely used in aviation, oil, electricity and other industries.
a. Annular bellows
This kind of tube is formed by connecting many ring diaphragms with concave centripetal semicircle ring, and the inner edge is connected with concave vest semicircle ring. Its raw materials are mainly made of pipe materials. The manufacturing method is relatively simple and has good elasticity. It can be used in places with high requirements for flexibility.
b. Spiral bellows
This kind of tube is formed by connecting the outer edge of the ring with the inner edge and semicircle ring. This kind of pipe has low requirement on flexibility and high requirement on strength.
2、 What is corrugated metal hose
There is a joint at each end of the corrugated metal hose. The outer layer is wrapped with a net and the inner layer is a thin stainless steel bellows.
1. Net cover
The main function of the hose is to wrap the hose into a metal mesh, which can be used to share the load of the hose. The installation of this layer of net cover can effectively prevent the damage caused by the friction between the two hoses, which plays a good shielding role.
2. Joint
The joint is an important part to connect the net cover and bellows, and it is also an indispensable part when connecting with other equipment. Most of these joints are made of stainless steel, and some joints which need to transport special medium are made of carbon steel. The joint can be divided into thread type, flange plate type and quick type.
a. The threaded joint can withstand high working pressure, and the joint has good sealing performance, but it is not easy to disassemble.
b. The flange plate joint is sealed with tenon and groove. The sealing performance of this joint is very good, but the processing is very difficult, and the sealing place is easy to be damaged.
c. The sealing ring of quick coupling is made of rubber. The tighter the sealing ring is pressed, the better the sealing performance is. Moreover, it can be assembled quickly without other tools.
