What are the types of high temperature resistant metal hose? What is a corrugated metal hose?
When it comes to high-temperature metal hoses, many people may not know what they are. In fact, these pipes are seen and used almost every day in our lives. For example, the pipes connected to water heaters and showerheads in our homes are high-temperature resistant metals. hose. What are the types of high-temperature metal hoses ? What is a corrugated metal hose? The following is just a brief look at it with Xiaobian.
First, the type of high temperature metal hose
What are the types of high temperature resistant metal hoses? 1. Threaded metal hoses
The raw material of this kind of hose is made of stainless steel, and it is mainly used as a protective tube for electric wires and cables. This hose has many advantages, very good flexibility, and good corrosion resistance.
What are the types of high temperature resistant metal hoses? 2. Corrugated metal hoses
This kind of hose is known as the skin tiger in our country. It has a long life and good sealing. It is widely used in aviation, petroleum, electric power and other industries.
a, ring bellows
This type of tube is a tube formed by connecting a large number of annular membranes and a concave semi-circular ring with a concave inner surface and a concave half vest. Its raw materials are mainly pipe-based, its manufacturing method is relatively simple, and its elasticity is very good. It can be used in places where flexibility is relatively high.
b. Spiral bellows
This type of tube is formed by connecting a ring-shaped outer rim with an inner rim and a half ring. This type of pipe requires less flexibility and has a higher strength requirement.
Second, what is a corrugated metal hose
Corrugated metal hoses have a joint at each end, the outermost layer is wrapped with a net sleeve, and the inner layer is a thin layer of stainless steel bellows.
1, net sets
The main function of the net sleeve is to share the static load on the hose and ensure that it can work safely. It is made of a lot of metal wire or metal braid and wrapped in the outermost layer of the bellows. The installation of this mesh cover can effectively prevent the damage caused by the two hoses rubbing against each other and play a good shielding effect.
2, connector
The joint is an important part that connects the net sleeve and the bellows, and is also an indispensable part when connecting with other equipment. Most of these joints are made of stainless steel. There are also some joints that need to transport special media made of carbon steel. Joints can be divided into three types: threaded, flanged, and fast.
a. Threaded joints can withstand high working pressures. This kind of joints have good sealing, but they are not easy to disassemble.
b. Flange disc type joint is sealed with tongue and groove. This kind of joint has good sealing performance, but it is very difficult to process and seal place is easily damaged.
c. The seal of the quick coupling is made of rubber. The tighter the sealing ring is, the better the sealing performance is, and it can be quickly assembled without the need of other tools.
Editor's summary: The above are the types of heat-resistant metal hoses that Xiaobian has shared for you. And what is the corrugated metal hose information, I hope to help you. If you want to learn more about decoration, you can follow this site.
