In the winter, many people should feel the stimulant of static electricity. When they say nothing, they place static electricity everywhere. The whole person of the electric power immediately comes to mind. For LED mobile advertising vehicles, it seems that this little electrostatic force is very small, but it will have some impact on the safety of driving. When the LED mobile advertising vehicle generates static electricity, it not only does not feel good to the driver's ride, but also affects the performance of the LED screen. Should we prevent the static electricity of LED mobile advertising vehicles? 1, can go to the auto city for LED mobile advertising vehicles to buy a device called the electrostatic discharge device is installed in the car, the electrostatic discharge device is through the internal metal wire and then will lead the static electricity generated in the cab to the discharge device Above, and then release the static electricity through the air and the ground, can effectively eliminate the static electricity in the LED mobile advertising vehicle. There are two types of electrostatic dischargers for LED mobile advertising vehicles. One is a grounded discharge method, and the other is a discharge type discharger. 2, the chemical fiber material is relatively easy to produce static electricity, if the LED mobile advertising vehicle seat cushion and seat cover use chemical fiber material inside the jewelry, the probability and the amount of static electricity generated will increase. In order to effectively avoid this phenomenon, it is best to choose some anti-static materials such as pure cotton, leather, etc. when selecting pads, seat covers, and seat cushions. Especially when choosing LED mobile advertising car mats and reverse disc sets, the best choice is pure cotton material. Although it may be more expensive than chemical fiber, life is priceless. 3. Since the air in the winter is relatively dry, the frequency of using air conditioners in LED mobile advertising vehicles increases the water content in the cab. However, reducing the use of air conditioners is also an effective way to prevent static electricity. Then we can put a wet towel on the dashboard. In the case of sunlight, the water will begin to generate water vapor due to the sun's irradiation, and then let the air in the LED mobile advertising vehicle increase the humidity, effectively reducing static electricity. produce. 4, can go to the auto city for LED mobile advertising vehicle to buy a device called the electrostatic discharge device is installed in the car, the electrostatic discharge device is through the internal metal wire and then will lead the static electricity generated in the cab to the discharge device Above, and then release the static electricity through the air and the ground, can effectively eliminate the static electricity in the LED mobile advertising vehicle. There are two types of electrostatic dischargers for LED mobile advertising vehicles. One is a grounded discharge method, and the other is a discharge type discharger. Stainless Steel Pipe is a hollow round steel, mainly widely used in petroleum, chemical, medical, food, light industry, machinery and instruments and other industrial transportation pipeline and mechanical components, etc.. In addition, the bending and torsion strength of the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structure. Also used for production of various conventional weapons, artillery barrel, etc.
Preparation of stainless steel seamless pipe of the production process a. bar; B. heating; C. hot rolling perforation; D. cutting head; e. pickling; F. grinding; g. lubrication; h. cold processing; I. degreasing; J. solid solution heat treatment; K. straightening; L. pipe cutting; M. pickling; n. the finished product inspection.
classification
Stainless steel pipe material for ordinary carbon steel, quality carbon structural steel, alloy structural pipe, alloy steel and bearing steel pipe, stainless steel pipe and to save precious metals and meet the special requirements of double metal composite pipe, coating and coating tube. Stainless steel tube of a wide variety of uses, its technical requirements are different, the production method is also different. The current production of steel pipe diameter range 0.1 - 4500mm, wall thickness range of 0.01 ~ 250mm. In order to distinguish the characteristics, it is usually classified as follows.
Stainless steel pipe according to the production methods are divided into two major categories of seamless tube, and welded tube, Seamless Steel Pipe and as hot-rolled steel pipe, tube cold rolling, cold drawing tube and tube extrusion etc., cold drawing, cold-rolled is secondary processing of steel pipe, welded pipe branch is a straight seam welded pipe and spiral welded pipe.

Production process
Production technology of stainless steel welded pipe:
The raw materials - welding pipe - end repair - polishing -- Inspection (printing) - Packaging - shipment (warehousing) (decorative pipe)
Raw material points - welding pipe heat treatment -- correction - straightening straight - xiu end - pickling and hydraulic pressure test and test (printing) - Packaging - shipment (12.5) (welded pipe industry piping pipe)
Hardness
Stainless steel tubes are commonly used in general, the Vivtorinox three hardness indicators to measure the hardness.
Vickers hardness
Vivtorinox hardness test is a kind of indentation test method, which can be used to measure the hardness of thin metallic materials and surface layer. It has the main advantages of the method of the method of the law of the family and the law of the law, but it is simple and easy to use, but it is not easy to use the method of the Vivtorinox method.
Hardness test
Stainless steel tube inner diameter above 6.0 mm, wall thickness in 13mm following annealing of stainless steel tubing can used to W-B75 type Merriam Webster Hardness Meter, it tests the very fast and easy, suitable for of stainless steel pipes do quick and nondestructive inspection. The inner diameter of the stainless steel tube is larger than 30mm, and the wall thickness is larger than that of 1.2mm stainless steel pipe. The hardness of HRB and HRC is tested by using the hardness tester. Stainless steel tube inner diameter greater than 30mm, wall thickness less than 1.2mm of stainless steel pipe, using the surface of the hardness tester, test HRT or HRN hardness. The inner diameter is less than 0mm, more than 4.8mm of stainless steel pipe, using the tube special for the hardness tester, test HR15T hardness. When the inner diameter of the stainless steel pipe is larger than 26mm, the hardness of the inner wall of the tube can be tested by the tester of the surface of the tube or the surface of the hardness tester.
