It is mainly used to manufacture electrical devices such as generators, buses cables, switchgear, and thermal conductive devices such as flat plate collectors for heat exchangers, pipes, and solar heating equipment. Common copper alloys are divided into three categories: brass, bronze and white copper. Pure copper plate is a purplish red metal commonly known as & quot; copper plate& quot;, & amp; quot; red copper plate& quot; or & quot; red copper plate& quot;.Disadvantages of copper pipe As far as copper pipe is concerned, high production cost and high price are its biggest disadvantages. Compared with other pipe fittings, the cost of copper pipe is much higher, and the connection at the copper pipe interface requires high construction technology level.porch,When heating steel pipes, the temperature is slightly higher than when heating copper pipes.Although the opening continued the weak trend, the intraday transactions improved, and the prices of some copper bar manufacturers rose. From the specific situation,porchH65 brass plate, although the manufacturer feedback that the shipment is average, the mentality is relatively calm, the market inventory is not much and the manufacturer is not willing to significantly reduce the price. In terms of the market, the transaction of strip steel is better than other steel varieties, and the downstream mainly focuses on callback buying without panic inventory clearing. It can be seen that although the steel market continues to shake, the overall demand for strip steel remains in a good state.Bockla,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.Advantages: good quality, fine structure, high density, high pressure resistance, large bending deformation suitable for frequent cold and heat exchange, large temperature difference in working environment, and large size copper tube can be produced.The hard copper tube is not artificially treated after being drawn or extruded, so that it can be naturally formed. At this time, the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore, the hard copper tube is generally straight.

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, it can be annealed at ~ ℃ to prevent & quot; self cracking& quot; by stress.The difference between hard copper tubes and soft copper tubes in use Hard copper tubes can only be used as straight tubes and cannot be bent. Therefore, they are generally used in power plants, switches of electrical equipment, and places where the connection points are far away and do not need to be bent. Compared with soft copper tubes, the price of hard copper tubes will be lower. Although the name of the soft copper tube is soft tube, it can also be used as a hard tube, so the soft copper tube is used in more places, and can be used in a straight tube way, asell as in a coiled tube way. The length of the copper tube can be longer if the coil is used. If the connection point is longer, it can be cut randomly according to the length, so as to prevent leakage when welding the copper tube. Soft copper pipes are used in many refrigerators, air conditioners and other places where bending pipes are needed. When we use copper, we need not consider the preservation problem unless we buy a small amount at home. For example, large manufacturers use copper units to buy a large number of copper pipes once,porchBronze tube, so there will be a problem. I believe some people do not know how to store unused copper materials, Now let s ask our staff to introduce the storage method of copper for you.ranking,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.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.The copper tube shall be heated and welded first, and then the joint shall be heated until the heated part turns dark red. At this time, when the filler metal contacts the tube, the filler metal shall melt.

If the corrosion on the copper surface is found to be slight, it can be erased with linen copper wire,Advantages: good quality, fine structure, high density, high pressure resistance, suitable for frequent cold and heat exchange large temperature difference in working environment, and large size copper tube can be produced.Air conditioning copper tube production technology Upward lead method: This production method is electrolytic copper after copper tube is directly melted.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?porch,The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm, the elongation is ~%, and the Brinell hardness (HB) is ~The copper bar market declined steadily this week, with a decline of - yuan. Due to low pig iron inventory, some steel mills in Jiangxi have resumed purchasing recently, but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently, the steel market has been in shock and adjustment, and the merchants are unstable. Steel mills in Hebei, Tianjin and other regions have stopped producing pig iron for steelmaking. Now, it is mainly expected to make inquiries. However, the price of iron mills has been lowered.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.
