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.So far as the storage method of copper materials is concerned, we should properly keep the copper products we buy, extend the service life of copper and ensure its performance to avoid unnecessary losses.Chumbang,Methods of copper pipe anti-corrosion Strengthen scientific research.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.Pumalanga,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, 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.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, the copper tubes will become soft, which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.It is said that due to the optimistic future and tight resources, some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well, and the price of raw materials has risen, so the iron price has risen. The iron mills have a high enthusiasm for producing steel, so there is not much cast iron resources, and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting, and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand, the pig iron market is performing well and is expected to continue to operate strongly in the short term.

If the corrosion on the copper surface is found to be slight, it can be erased with linen copper wire, but it is not recommended to apply oil for preservation.First of all, brass pipe is a non-ferrous metal pipe 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, 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.Advantages: good quality, high density, high pressure resistance, large bending deformation, suitable for frequent cold and heat exchange, large temperature difference in working environment, and large size copper tube can be produced.High quality and low price,The blowpipe shall be perpendicular to the lead pipe during welding, and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.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,Chumbang6063 aluminum bar, it is mainly expected to make inquiries. However, due to the lower price of raw materials, the price of iron mills has been lowered.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.

Disadvantages: low output, high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation, which is the development direction of copper tube industry in the future.Create brilliance,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,Chumbang321 stainless steel coiled plate, 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.Many people do not fully understand the storage method of copper tubes in the process of use and production methods.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, which are easily corroded, so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.Chumbang,Although the opening continued the weak trend, the intraday transactions improved, and the prices of some copper bar manufacturers rose. From the specific situation, although the manufacturer feedback that the shipment is average, the mentality is relatively calm the market inventory is not much, and the manufacturer is not willing to significantly reduce the price. In terms of the market, the transaction of strip steel is better than other steel varieties and the downstream mainly focuses on callback buying without panic inventory clearing. It can be seen that although the steel market continues to shake, the overall demand for strip steel remains in a good state.At present, the fundamentals faced by the domestic copper bar market are still mixed. On the one hand, the market supply is expected to shrink, but on the other hand,Chumbang304 stainless steel plate, the northern market has entered the off-season of demand, domestic steel prices will enter the operating track of range consolidation. To sum up, considering the current situation of demand and inventory in the steel market, it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching, environmental protection phenomena such as steel mills are still going on, and black series speculation is still taking place. But personally, the fluuation range of the market in this region is limited, and businesses can operate flexibly on a short-term basis, and the shipment transaction is * * *.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.
