Advantages: good quality,Moncao Aluminum plate, fine structure high density, large bending deformation, suitable for frequent cold and heat exchange, large temperature difference in working environment,Soft water is easy to cause copper pipe corrosion.If you want to avoid this kind of situation for a long time, you can choose passivation treatment. In this way, not only is the copper surface serious, it can be cleaned under normal circumstances, but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment, so this effect is very good.Kalutara,The simplest way is to use copper cleaner. Brass, red copper, bronze, etc. can be used. Oil stains, fingerprints, oxide layers, etc. on the surface can be cleaned with copper cleaner first.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, 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.This week (-, the market price of red copper bar rose, and the transaction was not ideal. On the bidding day of Shagang last weekend, the price was stable to support the market, and the rising of billets at the weekend drove the market up in a wave, and the price of variety wire rods also rose by yuan at the weekend. However, it was reported that the deal was very poor, which led to the price being s table for the next two days. Until Wednesday, due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving, the market lowered the price. Market price changes, Xinji rose yuan on the rd; For the future market, the off-season is coming, the demand is weakening, and the market wait-and-see mood is getting stronger. But when winter comes, the environmental protection inspection is becoming more and more strict, which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.

Save materials and total cost, stability and performance, and can save maintenance.As theation effect of copper material on the agent is weak, the dissolved oxygen and air bubbles in it will corrode it.According to * * new data, in September China s imported iron ore * * * broke through the million ton mark,Moncao Heat dissipation copper tube, 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.market,In Jiangyin market, another distribution center, the overall inventory of the current circulation link is about tons, the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However,Moncao 12Cr1MoV alloy steel plate, from the perspective of the policy port of the steel plant, the overall production situation of Nangang, Hengrun Dada, etc. is relatively normal, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.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 room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm the elongation is ~%, and the Brinell hardness (HB) is ~

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, 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.production costs,Advantages of red copper tube Durability: copper has stable chemical properties, integrating cold resistance, heat resistance, pressure resistance, corrosion resistance and fire resistance, and can be used in different environments for a long time.Dissolved oxygen in water is a major factor in copper pipe corrosion.The market price of Zhengzhou copper bars is basically stable, and the shipment is not good. In terms of tube blank: today, Shandong Luli tube blank slightly reduced by yuan, and the current mainstream ex factory price is - yuan. In terms of pipe plant: Linyi Pipe Plant locked the price for a week. With a stable market mentality, the factory price of hot rolled seamless pipes is now between - yuan. On the market side: with the arrival of the off-season, traders generally ship goods at a high price. Replenishment is mainly to maintain the existing inventory, and there is no large replenishment plan. The demand is sluggish, and the market price of Zhengzhou copper bar is expected to be stable and declining.Moncao ,The second of the five application fields of red copper plate T, red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels, distillation pots, brewing pots, etc.Tangshan billets rose sharply last weekend, steel mills in some northern cities implemented production restriction, and some domestic economic data improved, which boosted manufacturers confidence. Today steel prices generally rose. However, with the approaching meeting and the rainfall in the south caused by the typhoon, the construction progress of the downstream construction site is affected, which is not conducive to the continuous demand. The high spot price transaction today is weak, which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow, integrating cold resistance, pressure resistance, corrosion resistance and fire resistance, and can be used in different environments for a long time.
