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,Sukabumi45 # round steel, the same below), the * mm copper bar was yuan, and the * mm copper bar Henan copper bar was yuan.In Jiangyin market, the overall inventory of the current circulation link is about tons, 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.Sukabumi,If the copper tube is blocked during use, they should be stored separately according to the different components, and should not be mixed together. The copper surface may have electrolytes, which has a large impact.Stoke on Trent especially with other materials such as rubber,Disadvantages: low output, high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation, which is the development direction of copper tube industry in the future.Four of the five major application fields of copper plate, copper bar and copper pipe: copper is used as various pipes, pipe fittings and decorative devices in the construction industry.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 mentality is relatively calm, 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,SukabumiStainless steel plate, 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 copper bar market declined steadily this week, with a decline of - yuan. Due to low pig iron inventory, some steel mills in Jiangxi have resumed purchasing recently, but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently, the steel market has been in shock and adjustment, and the merchants are unstable. Steel mills in Hebei, Tianjin and other regions have stopped producing pig iron for steelmaking. Now, it is mainly expected to make inquiries. However due to the lower price of raw materials, the price of iron mills has been lowered.Corrosion caused by water with high chloride ion content.After : on October , continue to implement the measures of stopping and limiting production specified in TZBZ [] No. document. All sintering machines and shaft furnaces using wet desulphurization in iron and steel enterprises in the city were shut down, and sintering machines using semi dry desulphurization continued to be shut down for %. The access of vehicles is alicted. The port collection and distribution vehicles are prohibited from entering and leaving the port area. The city s steel, coking,Sukabumi201 stainless steel plate, electric power, cement, chemical and other key vehicle enterprises are not allowed to transport vehicles into and out of the plant. After : on October , the vehicle enterprises in the above industries will implement % of the peak load shifting emission reduction measures. It is estimated that the average daily consumption of sintering powder in Tangshan will be more than yuan, and the purchase of iron ore may still maintain a small amount of prudence. In addition due to the influence of industrial users & amp; quot; coal to gas& quot;, the recent performance of coke is weak. Therefore, in terms of steel plant production, the support of raw materials is weak.reformDisadvantages: Due to loose tissue and high pressure resistance, the pipe is only used to produce small air conditioning copper rods.After : on October , continue to implement the measures of stopping and limiting production specified in TZBZ [] No. document.

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.Quality department,Disadvantages: Due to loose tissue and high pressure resistance, the pipe is only used to produce small air conditioning copper rods.When stacking, reasonable stacking and first in first out shall be achieved.It has excellent conductivity, thermal conductivity, ductility and corrosion resistance.Sukabumi, 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.In August, the price of domestic medium and heavy plates fell sharply. As of August , the price center of ordinary carbon boards in leading cities had dropped to , down yuan/ton from the end of July. At the beginning of the month, affected by the macro bad news, and the recent poor performance of fundamentals, and some traders shipped at low prices. The market inventory rose, the inventory pressure was high, the stock shortage phenomenon disappeared, and the market transaction atmosphere was cold, and the spot price fell under pressure.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.
