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 $, 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.Let s 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 pipeo it is not easy to scratch. Therefore, high pressure resistance it is not easy to leak. Three. High temperature resistance, relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.Malmo,The evaporated zinc is immediately turned into zinc in the air, forming white smoke, which brings great difficulties to the operation and affects the health of welders. Therefore, in the places where decorative brass pipes are welded, cracks, zinc evaporation and so on.Copper pipe has the characteristics of and is the choice for the installation of water pipe, heat supply and refrigeration pipe.San Juan de Cologne,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.The difference between hard copper tubes and soft copper tubes in use Hard copper tubes can only be used as straight tubes and cannot be bent. Therefore, they are generally used in power plants, switches of electrical equipment, and places where the connection points are far away and do not need to be bent. Compared with soft copper tubes, the price of hard copper tubes will be lower. Although the name of the soft copper tube is soft tube, it can also be used as a hard tube, so the soft copper tube is used in more places, and can be used in a straight tube way, asell as in a coiled tube way. The length of the copper tube can be longer if the coil is used. If the connection point is longer, it can be cut randomly according to the length, so as to prevent leakage when welding the copper tube. Soft copper pipes are used in many refrigerators, air conditioners and other places where bending pipes are needed. When we use copper, we need not consider the preservation problem unless we buy a small amount at home. For example, large manufacturers use copper units to buy a large number of copper pipes once, so there will be a problem. I believe some people do not know how to store unused copper materials, Now let s ask our staff to introduce the storage method of copper for you.Let s 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.

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.

The so-called & quot; self-cleaning& quot; fluxes are generally not recommended because of their corrosivity.Heat and insert the copper tube and sleeve, and move the flame nozzle back and forth continuously between two points. Do not touch the flame directly with the flux.In the morning trading today, the price of domestic copper bar fell. According to the monitoring data of Lange Steel s cloud business platform, down yuan from yesterday. Futures prices fluctuated, and the prices of spot market manufacturers eased slightly today. According to the feedback, which caused the overall transaction blocked, and the mainstream manufacturers prices fell today.How many?,I don t know how to keep the copper tube.Hygiene and health: various modifiers, additives,Malmo1060 aluminum bar, additives and other chemical components of plastic pipes in copper pipes.Disadvantages: Due to loose tissue and high pressure resistance, the pipe is only used to produce small air conditioning copper rods.

Because of the characteristics of copper itself, it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it, the problem will be smaller, but if it is placed for a long time, the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.Installation requirements,The copper bar market declined steadily this week, with a decline of - yuan. Due to low pig iron inventory, some steel mills in Jiangxi have resumed purchasing 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,MalmoRed copper bar, it is mainly expected to make inquiries. However,MalmoBronze plate, due to the lower price of raw materials, the price of iron mills has been lowered.The more residual chloride ions, the deeper the corrosion pit of water.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 Wu an, 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 , the total inventory of medium and thick plates in Wu an 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, it should be said to maintain a relatively moderate level.Malmo,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 , the total inventory of medium and thick plates in Wu an 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.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.Today, the price of tube billets is up and down. At present, Jiangxin hot rolling is yuan, continuous casting yuan is down yuan, Dongfang hot rolling yuan is down yuan, Luli hot rolling yuan is down yuan, Tiangang hot rolling an is down yuan, production is stopped in mid January, Weigang hot rolling yuan is up yuan, Huaigang yuan is up yuan, Zhongtian yuan, Changqiang yuan, Linggang yuan.
