Although the opening continued the weak trend， the intraday transactions improved， and the prices of some copper bar manufacturers rose. From the specific situation， although the manufacturer feedback that the shipment is average， 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.
The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， the elongation is ~%， and the Brinell hardness (HB) is ~
덩 케 르 크ased 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， 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， there is no need to worry about safety. When choosing to decorate the house so as long as it is used correctly， few people ask about the water supply pipe of the house. In fact， 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，덩 케 르 크붉은 동관， 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，덩 케 르 크네모난 알루미늄 관， plastic coated copper tubes are widely used in superheaters， headers and main steam ducts of domestic HP，덩 케 르 크304 스테인리스 강판， UHP and subcritical power plant boilers. Third， large diameter pipes are mainly used as headers and main steam pipes with steam parameters below ℃.
동관의 세 가지 생산 방법 중에서 산화법이 가장 많다.금속 구리가 양극에 의해 산화되고 양극의 구리 이온이 관 재료에 부착되면 구리 관을 생산할 수 있기 때문이다.여기방법도 구리 재료를 생산하는 가장 상용하는 방법이다.그것은 오랫동안 사용되었을 뿐만 아니라 산화 반응을 통해 구리 파이프를 생산하는 성숙한 기술이 있습니다.이런 생산 방법은 중국 동관의 주요 생산 방법이다.
문외한The 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， thermal conductivity and yuan for Taizong yuan.
It has excellent conductivity， ductility and corrosion resistance.
At the opening this morning， the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform， the current market price of * mm Linyi copper bar was yuan (ton price， the same below)， the * mm copper bar was yuan， 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， and the rising of billets at the weekend drove the market up in a wave， and the price of variety wire rods also rose by yuan at the weekend. However， it was reported that the deal was very poor， which led to the price being stable for the next two days. Until Wednesday， 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， the demand is weakening， 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.
Corrosive agents such as calcium bicarbonate， inositol hexaphosphate， silicon phosphate crystal， etc. are added to the water to regulate the PH value of the water and the corrosion symptoms.
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?
분석 하 다.The application of copper tube The copper tube is generally used in the heat exchange equipment， and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids， and can also be used as pressure measuring tubes in instruments; In addition， the copper pipe is relatively firm， unlike other metals， which are easily corroded， so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.
The composite method of three production methods of copper tube is also a high-tech production method for this method. It is a copper material containing impurities. Those copper materials， copper alloys and composite copper materials are put together by electrochemical reaction to produce a nanocrystalline copper material， and then the material is purified to produce copper tube materials.
Advantages and scope of application of copper tube ground heating At present， ground heating is not only a comfortable heating method， 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.
