This week (-， the market price of red copper bar rose， and the transaction was not ideal. On the bidding day of Shagang last weekend， the price was stable to support the market， and the rising of billets at the weekend drove the market up in a wave， and the price of variety wire rods also rose by yuan at the weekend. However， it was reported that the deal was very poor， which led to the price being stable for the next two days. Until Wednesday， due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving， the market lowered the price. Market price changes Xinji rose yuan on the rd; For the future market， the off-season is coming， the demand is weakening， and the market wait-and-see mood is getting stronger. But when winter comes，서 소 핀20CrNiMo 합금 강판， the environmental protection inspection is becoming more and more strict， which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.

Market price changes， Xinji rose yuan on the rd; For the future market， the off-season is coming， the demand is weakening， and the market wait-and-see mood is getting stronger. But when winter comes the environmental protection inspection is becoming more and more strict， the price of domestic copper bar fell. According to the monitoring data of Lange Steels cloud business platform， the average price of * mm hot rolled strip in key cities in China is ， down yuan from yesterday. Futures prices fluctuated， and the prices of spot market manufacturers eased slightly today. According to the feedback the market was mainlysee yesterday， which caused the overall transaction blocked， and the mainstream manufacturers prices fell today.
The market opened today. Although the performance of Zitong Pai futures was modest， the overall market has stopped. The market mentality has not changed much sincekend. The price is stable， but some specifications are subject to negotiation， the overall market in Northeast China has entered the traditional off-season， and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing， and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature， the market was bleak.
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 Wuan 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.

When cutting the copper pipe of air conditioner， use tools such as clamps to fix the copper bar and then cut it， rather than fixing it by hand， to preveshaking and resulting in irregular cutting. After the cutting of the air conditioner copper pipe is completed， the cut parts need to be placed in a dry place， and then processed again after cooling， otherwise oxidation will occur due to high temperature. Liu Shuchen， director of the Resource Analysis Office of the Information Center of the Ministry of Land and Resources， said that copper bar manufacturers are currently in a period of adjustment in Chinas mining industry as a whole. In the long run， the mining super cycle driven by Chinas demand has not changed， especially the growth rate of the countrys economy. After the global economy may improve in the second half of the year， the global mining industry will rise again， and the W-shaped trend will fully emerge. In the second half of the year， there were signs of stabilizing and rebounding. In terms of the macro factors affecting the bulk commodities， the factors affecting the European market of tinned copper bars have gradually weakened， and the economic conditions of China and the United States have become the key factors affecting the bulk commodities. The European economic recession is a foregone conclusion， and the possibility of a crisis in the next period of time is also reduced. In recent years， the American market economy has shown the characteristics of better than expected in the first quarter and weaker than expected in the second quarter. Since January， the global price of medical copper tubes has gradually got rid of the main tone of this years shock and decline. "Air conditioning copper tubes show signs of stabilizing and rebounding. The three-month copper on the London Metal Exchange once rebounded nearly % from the years low point， and the market price has rebounded to around dollars per ton. Driven by this， products including aluminum， zinc and other products have also rebounded. Only nickel， a basic metal product， has remained weak.

포장 전략Advantages of red copper tube Durability: copper has stable chemical properties， heat resistance， pressure resistance， corrosion resistance and fire resistance， and can be used in different environments for a long time.

Advantages: good quality， high density， high pressure resistance， large bending deformation， suitable for frequent cold and heat exchange， large temperature difference in working environment， and large size copper tube can be produced.

Lets 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 pipe，o it is not easy to scratch. Therefore， it is not easy to leak. Three. High temperature resistance， due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.
서 소 핀To 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， 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.
