In the middle and late ten days, although there were good news such as the rise of futures and the increase of production restriction policy in Wu an region, due to the high inventory level, traders had no desire to increase prices, most of them had shipped goods, and spot prices lacked motivation to rise. The market inventory rose significantly. At that time the market inventory in Handan reached a high level after the festival. The sluggish demand performance for a long time led to the oversupply of the market, and the continuous rise of inventory led to the empty market mentality.The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm, the elongation is ~%, and the Brinell hardness (HB) is ~Kiskunfelegyhaza,Corrosion of copper in humid air is a chemical reaction, which makes coppeer look ugly. The above operations will make copper tubes beautiful. Bright brass tubes are still common in today s daily life and will be used in many places. But even with such a common product, many people still do not understand its performance characteristics. So, what are the excellent performance characteristics of this product? Here is a brief introduction to this article.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, 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.Janub as Surrah,Some steel mills in Liaoning are interested in purchasing pig iron, but the local resources are tight, and the iron mills quotations are on the high side, resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu, Shandong, Shanxi, Hebei, Henan and other regions is sluggish, and the inventory pressure of iron mills is increasing. As the price of raw materials decreases, the demand and cost support are weak, and there is no positive boost. The short-term pig iron market is weak and difficult to change.Later, Mexican scientists also found that copper has a . Recently, British researchers found that copper has a strong bactericidal effect. It is believed that in the near future, copper will make great contributions to improving human health. Copper plate T is named after its purple color. It is not necessarily pure copper, sometimes it also involves a few deoxidizing elements or other elements to improve raw materials and s, so it is also included in copper alloys. The processed materials of Chinese cor plate can be divided into four categories according to the composition: ordinary copper plate (T, T,Kiskunfelegyhaza2205 stainless steel plate, T, T, oxygen free copper plate (TU, TU and high-purity, vacuum oxygen free copper), deoxidized copper plate (TUP, TUMn), and special copper plate (arsenic copper, tellurium copper, silver copper) with a few alloy elements added. The conductivity and thermal conductivity of copper plate are second only to silver, and are widely used to manufacture conductive and thermal conductive devices. The red copper belt has outstanding corrosion resistance in the atmosphere, sea water, some non oxidizing acids, alkalis, salt solutions and a variety of organic acids (aic acid, and is used in the chemical industry. In addition,KiskunfelegyhazaH65 brass plate, the red copper plate has outstanding weldability and can be made into various semi products and products through cold and thermoplastic processing. In the s, the output value of copper plate exceeded that of other copper alloys.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, various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks, 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.

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, 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.How to preserve the copper tube? In order to protect the excellent performance of copper pipes from the impact of the environment, we need to do the following: First, select appropriate sites and warehouses, and keep the surrounding environment dry and ventilated. Do not stack together with acid, alkali, salt,Kiskunfelegyhaza304 stainless steel plate, etc.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, various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks, which is better in the off-season, 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.Trustworthy,The blowpipe shall be perpendicular to the lead pipe during welding, and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.In the middle and late ten days, although there were good news such as the rise of futures and the increase of production restriction policy in Wu an region, due to the high inventory level, traders had no desire to increase prices, most of them had shipped goods, and spot prices lacked motivation to rise. The market inventory rose significantly. At that time the market inventory in Handan reached a high level after the festival. The sluggish demand performance for a long time led to the oversupply of the market, and the continuous rise of inventory led to the empty market mentality.Red copper plate has ductility. Pure copper, which is as big as a drop of water, can be pulled up to two kilometers of thin wire or rolled into a transparent foil larger than a bed. The most valuable property of red copper row is that it has a very good conductive , second onlyver in common metals. But copper is much cheaper than silver, so it has become the & quot; protagonist& quot; of the electrical industry.

To sum up, the market in Northeast China is generally pessimistic based on the medium and long-term policies and the general environment, as well as the current inventory level in Shenyang. The low inventory level of copper platoon makes the whole market lack of motivation. The copper bar market in this city has stopped this year, 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.Free consultation,Copper tube is a kind of nonferrous metal tube which is pressed and drawn seamless tube. The copper pipe has good thermal conductivity, and is solid and corrosion resistant. It will not crack when compared with the ambient temperature, so it becomes the first choice for modern contractors to install the water pipe, heat supply pipe and refrigeration pipe in all residential commercial houses.The verdigris on the surface of brass tubes are formed by reacting with sulfides in the atmosphere.In consideration of the above factors, more and more steel plants have stopped production since October, and the production limit in Wu an and Tangshan heating seasons has been advanced. In addition, the formal implementation of production limit in & quot; +& quot; urban heating seasons after November by steel enterprises, the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high and the willingness to further replenish the inventory is not strong. In terms of supply, the quantity of * * * is relatively limited. In general the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection, the short-term iron ore market may lack upward momentum.Kiskunfelegyhaza,It has excellent conductivity, thermal conductivity, ductility and corrosion resistance.In Jiangyin market, another distribution center, slightly lower than the normal level. At the beginning of this week, the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However from the perspective of the policy port of the steel plant, the overall production situation of Nangang, Hengrun, Dada, etc. is relatively normal, and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.After the pipe is cleaned, the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately, so that dust and dirt will not pollute the capillary gap.
