In view of the current overall price difference， the local copper bar price continued to rise at a high level today， while the regions outside East China did not show an obvious follow-up trend， and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction， and the price support of copper bar is still strong. However， at present domestic real estate control is still being tightened. The markets expectation of future demand is weakening， and the markets fear of heights appears after the price rises.Today， 녹 제거， 인화 및 둔화
Tangshan billets rose sharply last weekend， steel mills in some northern cities implemented production restriction， and some domestic economic data improved， which boosted manufacturers confidence. Today， steel prices generally rose. However， with the approaching meeting and the rainfall in the south caused by the typhoon， the construction progress of the downstream construction site is affected， which is not conducive to the continuous demand. The high spot price transaction today is weak， which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow，흠골 라냉각 구리 파이프， and some businesses may reduce prices and take goods.
라 이브 르Although 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 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， 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 application of copper tube The copper tube is generally used in the heat exchange equipment， and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids， and can also be used as pressure measuring tubes in instruments; In addition， the copper pipe is relatively firm， unlike other metals， so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.

It mainly refers to strengthening the research on copper pipe corrosion and formulating a complete and scientific copper pipe use plan.
Overview of three production methods of copper tube Copper tube is a very important material for copper materials. There are many ways to complete the production of this copper tube. For copper pipes， the following three methods are generally used to produce materials. The copper tubes produced by these three methods are not only very good in performance， so what are the three production methods for copper tube?
투자 하 다.Among the three production methods of copper tube the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material， the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time， but also has a mature technology， which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.
Copper pipe has the characteristics of and is the choice for the installation of water pipe， heat supply and refrigeration pipe.
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，흠골 라GCR15 합금 원강， 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， the environmental protection inspection is becoming more and more strict， 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.
계획 하 다.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.

When welding， 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.
Red copper inventory in key areas has risen continuously， but the total pressure is not big. From the current overall inventory situation of the main distribution centers Wuan， Jiangyin and Lecong， the inventory level remains relatively moderate， and the pressure on the market is relatively small. In Wuan market， according to the data as of May ， the total inventory of medium and thick plates in Wuan was close to tons， increasing by tons on a weekly basis. In late April， it reached tons lower in the year， down tons from the high level after the Spring Festival， and rose for three consecutive weeks. In terms of the ovquantity， it should be said to maintain a relatively moderate level.
