I don t know how to keep the copper tube.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.LAN Feng,Corrosion caused by impure copper materials.Advantages and scope of application of copper tube ground heating At present, ground heating is not only a comfortable heating method, but also a symbol of modern life quality. More and more houses, public buildings, sports facilities, industrial facilities and other places begin to use ground heating radiator, which is an important part of ground heating. Due to the corrosion resistance of copper, copper tubes are selected as the main material of radiator in many places.Bayanhongor,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 difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow, and some businesses may reduce prices and take goods.When placing, they should be stored separately according to the different components, and should not be mixed together. The copper surface may have electrolytes, so it will react, which has a large impact.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, resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu, Shandong, Shanxi, Hebei, Henan and other regions is sluggish, and the inventory pressure of iron mills is increasing. As the price of raw materials decreases, the quotation of iron mills continues to decline. At present, the demand and cost support are weak, especially other acid materials and alkali materials,LAN Fengbrass plate, in the warehouse to prevent mutual reaction.Corrosive agents such as calcium bicarbonate, inositol hexaphosphate, silicon phosphate crystal, etc. are added to the water to regulate the PH value of the water and the corrosion symptoms.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 Meixin yuan yuan for Baoda yuan, and yuan for Taizong yuan.Online consultation,LAN Feng310s stainless steel coil,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 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.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, resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu, Shandong, Shanxi, Hebei, Henan and other regions is sluggish, and the inventory pressure of iron mills is increasing. As the price of raw materials decreases, the quotation of iron mills continues to decline. At present, 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.At the opening this morning, the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform, the current market price of * mm Linyi copper bar was yuan (ton price, the same below), the * mm copper bar was yuan, and the * mm copper bar Henan copper bar was yuan.

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.reform,To sum up due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants, the gradual emergence of supply and demand pressure and the weakness of raw material support, among which the contraction of market demand has a greater impact. Therefore, the author believes that in the short term, the spot building materials do not have the possibility to rise significantly, and the price of building materials may mainly operate in shock, but with the shrinking demand,LAN FengT2 copper bar, the supply and demand pressure becomes prominent, However, considering the influence of winter storage and other factors, it is still possible for merchants to lower the spot price in November.First of all, which can generally be used as a water pipe. Because this pipe product is a seamless product, it can effectively prevent water pipe leakage. Of course, because this kind of copper tube product has its own hardness and good corrosion resistance, it can also be used as heating and cooling tubes. The brass tube not only has good corrosion resistance and hardness, but also has strong plasticity. Compared with other metal pipe products, this kind of pipe has the characteristics of bending, inversion, and not easy to break. This kind of pipe product is widely used in daily life and has a longer service life. Brass pipes have strong frost heave resistance and impact resistance. Copper pipe products with these advantages have a long service life and can play an important role in building water supply systems. In short, as long as this copper tube product is installed, it is safe and reliable, and even does not need maintenance.The composite method of three production methods of copper tube is also a high-tech production method for this method. It is a copper material containing impurities. Those copper materials, copper alloys and composite copper materials are put together by electrochemical reaction to produce a nanocrystalline copper material, and then the material is purified to produce copper tube materials.LAN Feng,Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.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 and rose for three consecutive weeks. In terms of the ovquantity, it should be said to maintain a relatively moderate 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, which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.
