Generally, oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.Five of the five major application fields of copper plate, copper bar and copper tube: copper is used in medicine. In the s, Chinese medical inventors Liu Tongqing and Liu Tongle found that copper has extremely strong s, and successfully developed the corresponding & quot; Cancer Suppressing & quot;, which is successful in the near future.New Kuznetsk,As the copper pipe is easy to process and connect, it can save materials and total cost, stability and reliability, and can save maintenance during installation.If the corrosion on the copper surface is found to be slight, it can be erased with linen copper wire but it is not recommended to apply oil for preservation.Zhovti Vody,The excellent performance of copper pipe The copper pipe has the characteristics of and, which makes it a suitable choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial housing.If you want to make the copper surface become bright again, you can polish it with copper point solution. It can not only make the copper surface brighter, but also quickly remove the rust and oxide layer on the copper surface to restore the luster of the copper itself.According to * * new data, China s imported iron ore * * * broke through the million ton mark, reaching million tons, a record high; From January to September, and the annual import volume is expected to exceed billion tons. However, judging from the shipment of imported ores after the National Day, due to the rapid declinecline in iron ore prices the iron ore price index once fell below $,New Kuznetsk2205 stainless steel plate, which reduced the enthusiasm for the shipment of imported ores. In addition, and the supply of some domestic mines has been greatly affected. The current operating rate of domestic mines is percentage points lower than the previous peak, which is likely to decline further in the future.

Overview of three production methods of copper tube Copper tube is a very important material for copper materials. There are many ways to complete the production of this copper tube. For copper pipes, the following three methods are generally used to produce materials. The copper tubes produced by these three methods are not only very good in performance, but also very convenient to operate. There are three production methods for copper tube, so what are the three production methods for copper tube?Under the action of high welding temperature the evaporation amount of zinc is as high as % during shielded metal arc welding. A large amount of zinc evaporation leads to the decline of mechanical properties and corrosion resistance of welded joints, and also increases the sensitivity to stress corrosion.For small diameter pipes, when using filler metal, the length of filler metal is allowed to be equal to the diameter of the pipe, which is enough to fill the weld crater. One of the five major application fields of red coppr plate T, red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries, accounting for more than half of the total consumption. Used for various cables and wires,New KuznetskAluminum plate, motors and transformers, switches and printed circuit boards; In the manufacture of machinery and transport vehicles, it is used to manufacture industrial valves and accessories, instruments, sliding bearings, molds, heat exchangers, pumps, etc.How much is it, they should be stored separately according to the different components, and should not be mixed together. The copper surface may have electrolytes, so it will react, especially with other materials such as rubber, which has a large impact.It has excellent conductivity,New Kuznetsk6061 aluminum bar, thermal conductivity, ductility and corrosion resistance.The simplest way is to use copper cleaner. Brass, red copper, bronze, etc. can be used. Oil stains, oxide layers, etc. on the surface can be cleaned with copper cleaner first.

Because of the characteristics of copper itself, it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it, the problem will be smaller, but if it is placed for a long time, the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.Executive standard,Do not store too many other products, especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction.As the inner wall of the pipe rubs with water, its film is damaged, resulting in erosion corrosion. The higher the water pressure, the greater the flow, and the more serious the corrosion.Disadvantages: low output, high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation, which is the development direction of copper tube industry in the future.New Kuznetsk,Save materials and total cost, stability and performance and can save maintenance.So far as the storage method of copper materials is concerned, we should properly keep the copper products we buy, extend the service life of copper and ensure its performance to avoid unnecessary losses.When welding, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.
