At present, the fundamentals faced by the domestic copper bar market are still mixed. On the one hand, the market supply is expected to shrink, the northern market has entered the off-season of demand, and the market s expectation of future demand is pessimistic. In the short term, domestic steel prices will enter the operating track of range consolidation. To sum up, considering the current situation of demand and inventory in the steel market, it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching, environmental protection phenomena such as steel mills are still going on, and black series speculation is still taking place. But personally, the fluuation range of the market in this region is limited, and businesses can operate flexibly on a short-term basis, and the shipment transaction is * * *.Copper pipe has the characteristics of, and is the choice for the installation of water pipe, heat supply and refrigeration pipe.Frankfurt on main,Air conditioning copper tube production technology Upward lead method: This production method is electrolytic copper after copper tube is directly melted.The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.Thivai,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 ,Frankfurt on main6061 aluminum tube, the production restriction measures specified in this Notice were implemented.If you want to make the copper surface become bright again, you can polish it with copper point solution. It can not only make the copper surface brighter but also quickly remove the rust and oxide layer on the copper surface to restore the luster of the copper itself.On October , 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of million tons of pig iron and million tons of crude steel, and all the de capacity equipment had been shut down and withdrawn.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.

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.Continuous casting and rolling method: This production method is to directly cast hollow copper billets after electrolytic copper smelting, and use planetary rolling method to produce copper tubes.If the corrosion on the copper surface is found to be slight, but it is not recommended to apply oil for preservation.Where to sell API,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.Red copper bars in other regions basically follow the price trend of Tangshan, in which the bid of Jiangsu Steel Works tends to be higher, and most of the downstream prices are asked, and the overall market transaction is fair. The steel mills in Wu an are limited in receiving orders, and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary, so they hold a cautious wait-and-see attitude. At prepresent, the steel market is in the & quot; golden third& quot; peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.When welding,Frankfurt on mainTinned copper bar, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.

On the other hand, in the steel plant, the lock price of the steel plant has been falling all the time, and the order receiving is poor. The capacity utilization rate of the steel plant is low, but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising, so the market price has fallen sharply. Subsequently, the futures market rebounded in a wave, and the spot price also increased with the increase. There was an instant of large volume of transactions. However, with the decline of black futures the market transaction volume shrank significantly. In addition, the inventory pressure was high, traders shipped at low prices, and the spot price fell under pressure. Due to the strong drop resistance of medium and thick plates, the drop amplitude and rate are less than those of threads.Pursuit of excellence,Let s elaborate on the advantages of copper pipe materials: copper pipe floor heating refers to a heating method that uses hot water as the thermal medium, circulates in the copper pipe heating pipe, heats the floor, and heats the floor through the ground in the form of radiation and convection heat transfer. I. The copper tube has fast heat dissipation effect and strong heat resistance. Even under the condition of high temperature water supply, the service life of the floor heating tube will not be affected. Two. Copper pipe is a metal pipeo it is not easy to scratch. Therefore, it is not easy to leak. Three. High temperature resistance, high pressure resistance, relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.Under the action of high welding temperature, and also increases the sensitivity to stress corrosion.It has excellent conductivity, thermal conductivity, ductility and corrosion resistance.Frankfurt on main,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.To sum up, the market in Northeast China is generally pessimistic based on the medium and long-term policies and the general environment, and it is hard to improve in the short and medium term. On the whole, the market price of Shenyang copper bars may be stable tomorrow.Disadvantages of copper pipe As far as copper pipe is concerned, high production cost and high price are its biggest disadvantages. Compared with other pipe fittings, the cost of copper pipe is much higher, and the connection at the copper pipe interface requires high construction technology level.
