The production method of soft copper tube is basically the same as that of hard copper tube, that is, the annealing process is added compared with the hard copper tube. Annealing of copper tubes means that they are calcined in a high temperature furnace to change the arrangement of the elements in the copper tubes. However, after annealing, the copper tubes will become soft, which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.Advantages and scope of application of copper tube ground heating At present, but also a symbol of modern life quality. More and more houses, public buildings, sports facilities, industrial facilities and other places begin to use ground heating radiator, which is an important part of ground heating. Due to the corrosion resistance of copper, copper tubes are selected as the main material of radiator in many places.Kong Jing,Air conditioning copper tube production technology Upward lead method: This production method is electrolytic copper after copper tube is directly melted.It is mainly used to manufacture electrical devices such as generators, buses, cables, switchgear, transformers, and thermal conductive devices such as flat plate collectors for heat exchangers, pipes,Kong JingStainless steel plate, 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;.Gharyan,With the advent of heating season, the raw material support of red copper row is weak. Under the influence of heating season and environmental protection production restriction, steel mills in some regions began to implement the production restriction measures for blast furnaces in heating season, and the demand for iron ore was weakened. In addition, the production restriction policy was issued in Tangshan today. From : on October to : on October , the production restriction measures specified in this Notice were implemented.Four of the five major application fields of copper plate, copper bar and copper pipe: copper is used as various pipes, pipe fittings and decorative devices in the construction industry.I don t know how to keep the copper tube.

The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm, the same below) yuan, yuan for Jin Zhengyang yuan, yuan for Ruigang Lianlian yuan for Baoda yuan, yuan for Meixin yuan, and yuan for Taizong yuan.For the production and processing of sculpted copper tubes, the sheet metal shall be first opened in the sheet metal workshop according to the dimensions shown in the drawings, and then use the bending machine to form the edge according to the drawing forming diagram. The shaped copper pipe shall also be installed with reinforcing ribs as required, and the four corners of the shaped plate shall be welded well. The welded parts shall be sent to the grinding workshop, and the spraying surface shall be polished and the welding interface shall be polished and leveled. The polished modeling copper pipe is then sent to the spraying workshop for processing. Before spraying, the surface of the sculpted copper pipe shall be chrome treated and the process hole shall be drilled, so as to ensure that the sculpted copper pipe can be hung on the spraying line well, and the painting can be smooth without flow marks, and the color is consistent without color difference. After that, according to customer demand, the qualified products are pasted with protective film and bound with bubble film or wooden box.In Jiangyin market, another distribution center, the overall inventory of the current circulation link is about tons, slightly lower than the normal level. At the beginning of this week, the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However, from the perspective of the policy port of the steel plant, the overall production situation of Nangang, Hengrun, and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons, which is a medium normal level and the recent spot price of Lecong market has a large gap with that of the north.agent,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.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,Kong Jing1060 aluminum bar, 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 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.In August, the price of domestic medium and heavy plates fell sharply. As of August , the price center of ordinary carbon boards in leading cities had dropped to , down yuan/ton from the end of July. At the beginning of the month, affected by the macro bad news, and the recent poor performance of fundamentals,Kong JingHeat dissipation copper tube, the market mentality turned to pessimism, and some traders shipped at low prices. The market inventory rose, the inventory pressure was high, the stock shortage phenomenon disappeared, and the market transaction atmosphere was cold, the demand performance continued to decline, and the spot price fell under pressure.

The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.Executive standard,In view of the current overall price difference, the local copper bar price continued to rise at a high level today, and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction, and the price support of copper bar is still strong. However, at present, domestic real estate control is still being tightened. The market s expectation of future demand is weakening, the market price of copper bars in Shenyang is stable and the shipment is poor.Finished products must be stored indoors. During storage, they should be protected from direct sunlight to the copper tubes. During the transfer transportation and loading and unloading of copper tubes, rain should be avoided; In summer, the ambient temperature of copper pipe is high, and the speed of copper pipe surface is accelerated. When storing copper pipe pay attention to the principle of first in first out to reduce no loss; The copper pipe loading process is better carried out indoors to avoid the copper pipe being exposed to the sun, so as to accelerate the speed of the outer wall of the copper pipe. After the loading is completed, at least two layers of canvas shall be used to tightly wrap the whole vehicle materials; After loading, if the truck can not depart in time, the truck shall be driven to the back of the sun to prevent the goods from being exposed to the sun for a long time to absorb heat.However, it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits, Tangshan Iron and Steel Group Co., or to lay hidden dangers for the decline. As far as tomorrow is concerned, the price may still maintain a narrow range of shock operation pattern.Kong Jing,Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.Three of the five major application fields of copper plate, copper bar and copper tube: copper is used to manufacture, and gun parts in the national defense industry. Every million rounds of copper are produced, - tons of copper are needed.The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm, the elongation is ~%, and the Brinell hardness (HB) is ~
