Если вы хотите， чтобы медная поверхность снова стала яркой，PromeЖелтая медь， вы можете отполировать ее раствором медной точки. Он не только делает поверхность меди ярче， но и быстро удаляет ржавчину и окислительный слой с поверхности меди и восстанавливает блеск самой меди.
PromeAsed 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，Prome310s Сварные трубы из нержавеющей стали， 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， few people ask about the water supply pipe of the house. In fact， the material of water supply pipeline will greatly affect people S здоровье. 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 ons dissolved in water in the degreased copper tube， and copper ons 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 copper betus 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，PromeСвиток из нержавеющей стали， 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 ℃.
Учитывая эти факторы， с октября все больше и больше сталелитейных заводов прекратили производство， а производство в Вучжоу было ограничено; В Сиане и Таншане отопительный сезон был перенесен на более ранний срок. Кроме того， официально вводится ограничение производства; & quot; + & amp; & quot; Сталелитейные компании могут еще больше ухудшить спрос на железную руду в будущем после отопительного сезона в городе после ноября. Запасы железной руды на сталелитейных заводах относительно высоки， и готовность к дальнейшему пополнению запасов невелика. Что касается поставок， то четвертый квартал， как правило， является пиковым периодом для поставок импортной руды. Несмотря на то что добыча на внутренних шахтах снизилась из - за охраны окружающей среды， * * количество относительно ограничено. В целом， краткосрочному рынку железной руды может не хватить стимула для роста.

First of all， we should set up a warehouse. The temperature in the warehouse should be generally kept at - & deg; C， while the humidity should be normal. The room should be kept ventilated.
Safe and reliable: copper pipe combines the advantages of metal pipe and non - metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waSs; It is also easier to bend than ordinary metals has good toughness and high ductility， and has excellent anti vibration， anti impact and anti frost expansion properties.
One ofTion of copper tubes. The common wave shape is a single copper tube. Hyperbolic means that two different arcs overlap on the same surface， that is， starting from different circle centers， draw arcs in two radiii. The red copper tube is a module made of double curves designed according to the drawings. The red copper tube is light in weight， good in rigidity and high in strength. The shapes of the red copper tubes processed are different and can be processed into various geometric shapes such as arcs and spheres. It is beautiful， elegant and colorful. Let th S talk about the two main methods of processing and forming the copper tube: The hot processing and forming method is to roll the copper tube to a roughly hyperbolic shape， then heat it， then place it on the mold prepared in advance， then slowly beat it with a hammer， finally cut， weld， fold， polish and polish it. The whole process needs to be very careful to ensure the surface quality of the copper tube. This forming method is very suitable for parts with small model and large arc change. When the model size is relatively large and complex， it can be considered to break it into small pieces for forming， and then splice it into large pieces. For such copper pipes， the cost is high and the production period is long. Forming method of roll bending This method is to make some modifications on the roll bending machine， and change one of the shafts into a concave type and the other into a convex type. This method can form a regular copper tube like a sphere， with a small processing range， but it has great advantages for copper tubes with small radians. What problems should be paid attention to when designing the hyperboloid copper tube? Everyone knews that the design of the air conditioning copper tube is very important. To achieve the beautiful shape， exquisite workmanship and fashionable personality of the hyperboloid copper tube， first of all， the design is very critical. Some small copper tube coPanies are not mature enough in design and have not enough design experience， so they often have problems in design， Hyperbolic copper tube is very famous for preparing some details that we should pay attention to in the design. The sculpted copper tube is highly decorative， different shapes need to be molded for the sculpted copper tube， so the production process of sculpted aluminum veneer is relatively complex.
It has excellent conductivity， thermal conductivity， ductivity and corrosion resistance.

Подводя итог， рынок северо - восточного региона， как правило， пессимистичен на основе средне - и долгосрочной политики и общей среды， а также нынешнего уровня запасов в Шэньяне. Низкий уровень запасов медных рядов не дает стимула всему рынку. В этом году рынок медных палочек в городе остановился， и в краткосрочной и среднесрочной перспективе его трудно улучшить. В целом， рыночные цены на медные палочки в Шэньяне могут стабилизироваться завтра.
It is said that due to the optimistic future and tight resources， some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well， and the price of raw materials has risen， so the iron price has risen. The iron mills have a high enthusiasm for producing steel， so there is not much cast iron resources， and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting， the pig iron market is performing well and is expected to continue to operate strongly in the short term.

The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently， the terminal demand has also shrunk due to the sudden drop in temperature， causing a weak shock. According to the communication with local traders in Cangzhou， which is better in the off - season， and the shipment of some specifications has improved. However， the trading atmosphere in the small and medium - sized pipe market is still cold， and the demand is slowing down gradually. To sum up， it is expected that the market price of Cangzhou seamless pipe will be stable and weak in the near future.
