Since entering the volcano, sustained high temperatures, the ground surface temperature of up to fifty to sixty degrees Celsius in the afternoon, brought great discomfort to the people, but also brought a lot of safety hazards to the car. To this end, the Beijing Meteorological Bureau has launched a popular science video to remind the public that in the heat of the summer, the car must also prevent heat stroke. First of all, summer is the peak period of automobile tire explosion. Many citizens believe that reducing stress by deflation of tires can effectively prevent this problem. The auto consultant stated that tire pressure is high and it is easy to puncture tires. If the air pressure is low, it is easy to puncture the tires. The correct method should be to adjust the tire pressure to the lower limit of the specified value. If the standard pressure of a car tire is between 2.3 and 2.5 MPa, it can be adjusted to the lower limit of 2.3 MPa in summer. Water temperature gauges should also be watched during the summer. In summer, when the engine is overheated and the outside temperature is too high, the vehicle enters a high-fire period. If the water temperature is too high, there will be some obvious symptoms, such as a drop in engine power and air conditioning failure. Due to the high temperature, the engine may be deflagrated and the engine may experience abnormal operating noise. After these symptoms appear, the auto consultant advises the owner that he must not rush to get out of the front cover to check. The correct way is to park the car and let it cool down naturally. Because the water temperature is too high, it may have produced spontaneous combustion, the moment the front cover is opened, the air enters, and it easily burns; in addition, the already-opened cooling liquid may also burn people. When using air conditioners for cars in the summer, use external circulation as much as possible. If the parking time is long, more than 10 to 15 minutes, try not to take a cold ride in the car; the air conditioning filter is guaranteed to change every year. Don't rush to raise the window to the end within 2 minutes after air conditioning. Because the inner room inside the car and the air duct of the air conditioning are all plastic or rubber products, some harmful gases will be emitted. It is necessary to use these 2 minutes to discharge all the harmful gases to make the windows full. rising.
The main difference of metallized ceramic tube than regular ones is the applied metal layer on the appointed area of ceramic body. With the applied metal layer on the surface, it can realize the bonding aim between the ceramic tube to metal, ceramic tube to ceramic tube. The metal film will be attached on ceramic parts tightly under high temperature cure. Then the Ceramic Tubes could be brazed with kovar, stainless steel parts together directly.

In order to increase the wettability at brazing process, in common case, an additional metal plating will be covered on metallization layer further, mainly including nickle plating, gold plating and so on.
In the recent market, alumina metallized ceramic tube is one of most extensive technical parts. They are features of high bonding strength, excellent electrical insulation and mechanical strength.
Sometimes, high precision dimensions is needed to cater to the fitting purpose. With our in-house machining workshop, we are able to make the dimensional tolerance as expected according to customers' specification.
