Later, Mexican scientists also found that copper has a . Recently, British researchers found that copper has a strong bactericidal effect. It is believed that in the near future, copper will make great contributions to improving human health. Copper plate T is named after its purple color. It is not necessarily pure copper, sometimes it also involves a few deoxidizing elements or other elements to improve raw materials and s, so it is also included in copper alloys. The processed materials of Chinese cor plate can be divided into four categories according to the composition: ordinary copper plate (T, T, T, oxygen free copper plate (TU, TU and high-purity, vacuum oxygen free copper), deoxidized copper plate (TUP, TUMn), and special copper plate (arsenic copper, tellurium copper, silver copper) with a few alloy elements added. The conductivity and thermal conductivity of copper plate are second only to silver, sea water, some non oxidizing acids, alkalis, salt solutions and a variety of organic acids (aic acid, citric acid), and is used in the chemical industry. In addition,Bildar316L stainless steel coiled plate, the red copper plate has outstanding weldability and can be made into various semi products and products through cold and thermoplastic processing. In the s, the output value of copper plate exceeded that of other copper alloys.The market opened today. Although the performance of Zitong Pai futures was modest, the overall market has stopped. The market mentality has not changed much sincekend. The price is stable, but some specifications are subject to negotiation, and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold. In the middle of winter the overall market in Northeast China has entered the traditional off-season, and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing, the market was bleak.Bildar,Air conditioning copper tube production technology Upward lead method: This production method is electrolytic copper after copper tube is directly melted.Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.Znoimo,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, the total inventory of medium and thick plates in Wu an was close to tons 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, it should be said to maintain a relatively moderate level.Do not store too many other products, especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction.I don t know how to keep the copper tube.

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.The more residual chloride ions, the deeper the corrosion pit of water.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, 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, 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,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.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.Insert 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.

Insert 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.Trustworthy,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 excellent performance of copper pipe The welded copper pipe has the characteristics of firmness and corrosion resistance, which makes it a suitable choice for modern contractors to install the water pipe, heating pipe and refrigeration pipe in all residential commercial houses.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 ,BildarCopper clad aluminum bar, 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.Bildar,The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm, the same below) yuan, yuan for Jin Zhengyang yuan, yuan for Ruigang Lianlian, yuan for Baoda yuan, yuan for Meixin yuan, and yuan for Taizong yuan.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, unlike other metals, which are easily corroded, so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.On the other hand,BildarTinned copper bar, in the steel plant, the lock price of the steel plant has been falling all the time, and the order receiving is poor. The capacity utilization rate of the steel plant is low, but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising, so the market price has fallen sharply. Subsequently the futures market rebounded in a wave, and the spot price also increased with the increase. There was an instant of large volume of transactions. However, with the decline of black futures, the market transaction volume shrank significantly. In addition, the inventory pressure was high, traders shipped at low prices, and the spot price fell under pressure. Due to the strong drop resistance of medium and thick plates, the drop amplitude and rate are less than those of threads.
