장점: 품질이 좋고 구조가 정교하며 밀도가 높고 내압성이 높으며 구부러지고 변형이 크며 빈번한 냉열교환에 적합하고 작업환경의 온도차가 크며 큰 사이즈의 동관을 생산할 수 있다.
나 베 레 지 니 첼 니ased copper tube is made of oxygen free copper rod， which has good processing characteristics and can be punched， bent and other process design requirements. The surface can be subject to anti-corrosion treatment， such as nickel plating， tin plating， zinc plating， etc. The surface anti-corrosion can reach hours of fog test. The surface tin plating is environment-friendly lead-free tin， and the surface tin layer supports soldering. T degreased copper tube is mainly used for communication cabinet， transformer， charging pile， box type substation and other electrical facilities. The copper bar is harder than the plastic pipe and has the degree of common metal (the strength of the cold drawn degreased copper pipe is equivalent to that of the steel pipe with the same wall thickness). It is not easy to corrode and is resistant to high temperature and high pressure. It can be used in various applications. The main material of copper bar is copper. The melting point of copper is as high as ℃， and the temperature of hot water can be ignored for degreased copper pipe，나 베 레 지 니 첼 니7075 알루미늄 튜브， so as long as it is used correctly， there is no need to worry about safety. When choosing to decorate the house， few people ask about the water supply pipe of the house. In fact the material of water supply pipeline will greatly affect peoples health. T copper tube has strong capacity. Escherichia coli in the water supply will not continue to breed in the degreased copper tube， and more than % of the water will disappear after entering the degreased copper tube for hours. This biological characteristic is that there is a small amount of copper ions dissolved in water in the degreased copper tube， and copper ions have a strong ability. Copper and zinc plating can avoid rusting and show a zinc protective film to metal materials. The conductive metal material repair and color enhancement care agent I can generate the thickness of the metal material epoxy protection layer and the pipelincathodic protection layer， which can resist extreme weather and is suitable for the long-term surface of metal materials. The actual effect of salt and water corrosion resistance is good. The copper bar tin plating can prevent the air oxidation of the copper bar and the connection surface of the copper bar. In addition， the melting of metal tin and copper will produce aluminum alloy， which will improve the adhesion of copper strip coating. In addition， the conductivity of metal tin is good. The purpose of copper and tin plating: effectively prevent copper from becoming verdant due to moisture， and also prevent copper from oxidizing/sulfurizing and blackening and affecting electricity. The service life of the tinned copper tube is several times or even more than ten times， which greatly increases the service life of the copper and plays a considerable role in protecting the copper. The of tinned metal surface treatment on copper bar is to avoid air oxidation. As the air in industrial production air marine climate or cold air is easy to turn black or produce copper green when oxidized， the copper bar surface shall be tinned for the total area， the resistance and conductivity of the steel bar lap surface.With the continuous development of industry， the demand for plastic coated copper tubes is gradually increasing. Then how to apply wood grain paint on alloy pipes. Wood like paint is a kind of wood like paint. It is used for spraying plastic coated copper pipe and its process flow. Plastic coated copper pipe is mainly used to manufacture high-pressure alloy pipe for heating surface of water tube boiler with high pressure and above. In the morning market， the mainstream spot price quoted by Lianzhong was - yuan/ton， and the tax inclusive base price quoted by Hongwang and Chengde was - yuan/ton. On a month on month basis， part of the producing areas recalled yuan and the mainstream tax inclusive base price in the market changed from strongeak in the - plastic coated copper pipe supply and demand relationship. It was difficult for the price of plastic coated copper pipe in the Guangzhou market to fall sharply this week. Second， plastic coated copper tubes are widely used in superheaters headers and main steam ducts of domestic HP， large diameter pipes are mainly used as headers and main steam pipes with steam parameters below ℃.
On October UHP and subcritical power plant boilers. Third， according to the Economic and Information Commission oong Province， at the end of September ， Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel， and all the de capacity equipment had been shut down and withdrawn. On October ， the Development and Reform Commission of Handan City released the Plan for Handan City to Eliminate Excess Iron and Steel Capacity. Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.
고구마In 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， 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.
antages: low production cost and high production efficiency.
After : on October ， continue to implement the measures of stopping and limiting production specified in TZBZ [] No. document. All sintering machines and shaft furnaces using wet desulphurization in iron and steel enterprises in the city were shut down， and sintering machines using semi dry desulphurization continued to be shut down for %. The access of vehicles is alicted. The port collection and distribution vehicles are prohibited from entering and leaving the port area. The citys steel， electric power， cement， chemical and other key vehicle enterprises are not allowed to transport vehicles into and out of the plant. After : on October ， the vehicle enterprises in the above industries will implement % of the peak load shifting emission reduction measures. It is estimated that the average daily consumption of sintering powder in Tangshan will be more than yuan， and the purchase of iron ore may still maintain a small amount of prudence. In addition， due to the influence of industrial users "coal to gas"， the recent performance of coke is weak. Therefore， in terms of steel plant production， the support of raw materials is weak.

추천 컨설팅Remove the flame. If the filler metal does not melt， continue to heat the joint and try again. The melted filler metal is sucked into the casing port according to the capillary effect until a complete filler metal ring appears on the casing port. Remove the flame Pay special attention not to let the flame directly contact the filler metal. It should be the heat at the joint that melts the filler metal. In order to clean the copper pipe， the welding flux must have a degree of corrosivity， and shall be cleaned after brazing. The so-called "self-cleaning" fluxes are generally not recommended because of their corrosivity.
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.

This week (-， the market price of red copper bar rose， and the transaction was not ideal. On the bidding day of Shagang last weekend， the price was stable to support the market， due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving， the market lowered the price. Market price changes， Xinji rose yuan on the rd; For the future market， the off-season is coming， and the market wait-and-see mood is getting stronger. But when winter comes， the environmental protection inspection is becoming more and more strict， which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.
