Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand, the continuous decline of iron ore port inventory may end. In addition, according to the new statistics of * *, the available days of imported iron ore of steel mills are days, which is one day lower than that before the National Day, and is on the high side of history. The steel mill said that at present, the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction, the steel mill is not willing to replenish the inventory.I don t know how to keep the copper tube.Moita,When heating steel pipes, the temperature is slightly higher than when heating copper pipes.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 market s expectation of future demand is weakening, and the market s fear of heights appears after the price rises. Today, the market price of copper bars in Shenyang is stable and the shipment is poor.Sur,Do not store too many other products, especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction.Hygiene and health: various modifiers, additives, additives and other chemical components of plastic pipes in copper pipes.Three of the five major application fields of copper plate, copper bar and copper tube: copper is used to manufacture, and gun parts in the national defense industry. Every million rounds of copper are produced, - tons of copper are needed.

It has excellent conductivity, thermal conductivity, ductility and corrosion resistance.Water quality, water flow and flow of the pipe.In the first ten days of May, the overall order receiving quantity of Tianjin Hebei Henan Plate Plant was not ideal. According to the monitoring data, the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak. Due to the weak market shock, the overall order intake of the spot steel market was relatively weak. The total quantity of orders received in the first ten days of May is only about tons, while at the end of April, the total quantity of post settlement agreements of main steel plants can exceed tons.assets,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.The main force of iron ore futures closed at in The closing price of the day today was the same as that of the previous trading day, including * * * * , * * * , settlement price , trading volume and position volume . The intraday tradg volume decreased by compared with the previous trading day, and the position volume decreased by compared with the previous trading day. After six consecutive days of downward adjustment, there was a rebound at the bottom of the session today, but it was corrected again later, and the closing was flat.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, Shandong, Shanxi, Hebei, Henan and other regions is sluggish, 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.

On November , the market price of Cangzhou copper bar was stable. According to the monitoring data of Lange Iron and Steel s cloud business platform, the market price of * mm cold drawn steel produced in Linyi is yuan, the market price of * mm in Linyi is yuan, the market price of * mm in Jianlong is yuan the market price of * mm in Yuanhua is yuan, the market price of * mm in Baotou Steel is yuan, and the market price of * mm in Juneng thermal expansion is yuan.Interpretation and observation,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 the market mentality turned to pessimism, 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, the demand performance continued to decline,Moita321 stainless steel round steel, and the spot price fell under pressure.Brass tube Soft copper tube is called hose, and the tube is used to replace the hard one, so soft copper is widely used. Besides being in a straight line, you can also have coils and coils in the form of long advantages. When used at the connection point is long, cut according to the free length, and mechanical oil tube.pper tube Copper tube is easy to heat because of its light weight refrigerator, and it can also be used normally at low temperatures.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.Moita,Disadvantages of copper pipe As far as copper pipe is concerned, high production cost and high price are its biggest disadvantages. Compared with other pipe fittings, the cost of copper pipe is much higher,Moita310s stainless steel pipe, and the connection at the copper pipe interface requires high construction technology level.The production method of soft copper tube is basically the same as that of hard copper tube, that is, the annealing process is added compared with the hard copper tube. Annealing of copper tubes means that they are calcined in a high temperature furnace to change the arrangement of the elements in the copper tubes. However, after annealing, the copper tubes will become soft, which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.Remove the flame. If the filler metal does not melt,MoitaTinned copper bar, 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.
