Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe， characterized by light weight， good thermal conductivity， high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes， the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?

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， and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand， the pig iron market is performing well and is expected to continue to operate strongly in the short term.

Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.
To sum up， due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants， the gradual emergence of supply and demand pressure， and the weakness of raw material support， among which the contraction of market demand has a greater impact. Therefore， the spot building materials do not have the possibility to rise significantly， and the price of building materials may mainly operate in shock， but with the shrinking demand， the supply and demand pressure becomes prominent， However， considering the influence of winter storage and other factors， it is still possible for merchants to lower the spot price in November.

ased 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， 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， 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，조 보.321 스테인리스강 권재， the melting of metal tin and copper will produce aluminum alloy， 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， UHP and subcritical power plant boilers. Third， large diameter pipes are mainly used as headers and main steam pipes with steam parameters below ℃.

조 보.Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand， the continuous decline of iron ore port inventory may end. In addition， according to the new statistics of * *， which is one day lower than that before the National Day， and is on the high side of history. The steel mill said that at present， the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction， the steel mill is not willing to replenish the inventory.

To sum up， the gradual emergence of supply and demand pressure， and the weakness of raw material support among which the contraction of market demand has a greater impact. Therefore， the author believes that in the short term， the spot building materials do not have the possibility to rise significantly，조 보.6061 알루미늄 바， and the price of building materials may mainly operate in shock， but with the shrinking demand， the supply and demand pressure becomes prominent， However， considering the influence of winter storage and other factors， it is still possible for merchants to lower the spot price in November.
