Red copper inventory in key areas has risen continuously, Jiangyin and Lecong, the inventory level remains relatively moderate, and the pressure on the market is relatively small. In Wu an market, according to the data, as of May , 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, 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of million tons of pig iron and million tons of crude steel, and all the de capacity equipment had been shut down and withdrawn.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.Gra,The more residual chloride ions, the deeper the corrosion pit of water.Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe, characterized by light weight, good thermal conductivity, high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes, the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?Penonome,So far as the storage method of copper materials is concerned, we should properly keep the copper products we buy, extend the service life of copper and ensure its performance to avoid unnecessary losses.When stacking, it shall be stacked reasonably and placed first.According to * * new data, in September , China s imported iron ore * * * broke through the million ton mark, reaching million tons, a record high; From January to September, China s iron ore import increased by % to million tons, and the annual import volume is expected to exceed billion tons. However, judging from the shipment of imported ores after the National Day, due to the rapid declinecline in iron ore prices, the iron ore price index once fell below $,GraAluminum row of cold storage, which reduced the enthusiasm for the shipment of imported ores. In addition environmental protection inspection has become stricter, and the supply of some domestic mines has been greatly affected. The current operating rate of domestic mines is percentage points lower than the previous peak, which is likely to decline further in the future.

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.When installing, easy maintenance and small space occupation.The excellent performance of copper pipe The copper pipe has the characteristics of and, which makes it a suitable choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial housing.Design brand,GraCopper strip,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.Extrusion method: This production method is to cast copper ingots after smelting, the terminal demand has also shrunk due to the sudden drop in temperature and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.

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, 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,GraBronze tube, 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.technical service,Copper pipe has the characteristics of, and is the choice for the installation of water pipe, heat supply and refrigeration pipe.As theation effect of copper material on the agent is weak, the dissolved oxygen and air bubbles in it will corrode it.Remove the flame. If the filler metal does not melt, continue to heat the joint and try again. The melted filler metal is sucked into the casing port according to the capillary effect until a complete filler metal ring appears on the casing port. Remove the flame Pay special attention not to let the flame directly contact the filler metal. It should be the heat at the joint that melts the filler metal. In order to clean the copper pipe, the welding flux must have a degree of corrosivity and shall be cleaned after brazing. The so-called & quot; self-cleaning& quot; fluxes are generally not recommended because of their corrosivity.Gra,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.In addition, it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures, so copper pipes need to be selected for many times in other places.First of all, we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C, while the humidity should be normal. The room should be kept ventilated.
