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, the northern market has entered the off-season of demand, and the market s expectation of future demand is pessimistic. In the short term, 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, and the shipment transaction is * * *.Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe and businesses can operate flexibly on a short-term basis, characterized by light weight, good thermal conductivity, high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?Surat Sani,As the inner wall of the pipe rubs with water, its film is damaged, resulting in erosion corrosion. The higher the water pressure, the greater the flow, and the more serious the corrosion.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,On the other hand, in the steel plant, the lock price of the steel plant has been falling all the time,Surat SaniBronze tube, 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, 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.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,Surat Sani310s stainless steel welded pipe, the same below) yuan, yuan for Jin Zhengyang yuan, yuan for Ruigang Lianlian, yuan for Baoda yuan, yuan for Meixin yuan,Surat SaniLow alloy plate, and yuan for Taizong yuan.

In Jiangyin market, another distribution center, the overall inventory of the current circulation link is about tons, slightly lower than the normal level. At the beginning of this week, the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However, from the perspective of the policy port of the steel plant, the overall production situation of Nangang, Hengrun Dada, etc. is relatively normal, and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.If the copper tube is blocked during use, it is also very important to dredge it in time.Overview of three production methods of copper tube Copper tube is a very important material for copper materials. There are many ways to complete the production of this copper tube. For copper pipes, but also very convenient to operate. There are three production methods for copper tube, so what are the three production methods for copper tube?Management Department,Four of the five major application fields of copper plate, copper bar and copper pipe: copper is used as various pipes, pipe fittings and decorative devices in the construction industry.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.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.

Red copper bars in other regions basically follow the price trend of Tangshan, in which the bid of Jiangsu Steel Works tends to be higher, and most of the downstream prices are asked, and the overall market transaction is fair. The steel mills in Wu an are limited in receiving orders, and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary, and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak, so they hold a cautious wait-and-see attitude. At prepresent, the steel market is in the & quot; golden third& quot; peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.Quality inspection report,Disadvantages: Due to loose tissue and high pressure resistance, the pipe is only used to produce small air conditioning copper rods.Disadvantages: The pipe structure is loose, and it is not resistant to high pressure. It is only suitable for the production of small air conditioning copper pipes.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.Surat Sani,Red copper plate has ductility. Pure copper, which is as big as a drop of water, can be pulled up to two kilometers of thin wire or rolled into a transparent foil larger than a bed. The most valuable property of red copper row is that it has a very good conductive , second onlyver in common metals. But copper is much cheaper than silver, the price of domestic copper bar fell. According to the monitoring data of Lange Steel s cloud business platform, the average price of * mm hot rolled strip in key cities in China is , and the prices of spot market manufacturers eased slightly today. According to the feedback, the market was mainlysee yesterday, which caused the overall transaction blocked, and the mainstream manufacturers prices fell today.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.
