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 Wu an 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.The production method of soft copper tube is basically the same as that of hard copper tube,Jakarta304 stainless steel plate, 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.Jakarta,(Brass is a copper zinc alloy. Due to the low boiling point of zinc, which is only ℃, it is very easy to evaporate during welding, which becomes a problem in brass welding.The price of pig iron market rose by - yuan this week, and the transaction was fair. With the increase of coke price, the cost of ductile iron in Shanxi, Henan, Shandong and other regions has increased. In addition, with the gradual release of downstream demand, the inventory of iron plants is not large,Jakarta321 stainless steel coiled plate, and iron plants have successively raised their prices. There are few iron foundries in Shandong, Jiangsu, Hebei and Shanxi, and the inventory remains low. As the coke price rises and the cost increases, the price of iron foundries rises again.MutengeneInsert the pipe into the top of the bayonet,e the sleeve on the pipe to evenly apply the flux on the joint and confirm that the pipe is inserted into the bottom of the socket, then wipe off the excess flux, and the joint is assembled and can be heated.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 Juneng is yuan, the market price of * mm in Baotou Steel is yuan, and the market price of * mm in Juneng thermal expansion is yuan.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.

When stacking, it shall be stacked reasonably and placed first.For the deposited copper tubes, do not open the outer packaging as much as possible.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.Direct laborFour 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.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.Red copper plate has ductility. Pure copper, which is as big as a drop of water, second onlyver in common metals. But copper is much cheaper than silver, so it has become the & quot; protagonist& quot; of the electrical industry.

The copper bar market declined steadily this week, 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.Let's see, 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.The verdigris on the surface of brass tubes are formed by reacting with sulfides in the atmosphere.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.Jakarta,Jakarta2205 stainless steel plate,Red copper bars in other regions basically follow the price trend of Tangshan, in which the bid of Jiangsu Steel Works tends to be higher, and most of the downstream prices are asked, and the overall market transaction is fair. The steel mills in Wu an are limited in receiving orders, and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary, and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak, so they hold a cautious wait-and-see attitude. At prepresent, the steel market is in the & quot; golden third& quot; peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.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.It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found, they must be isolated.
