According to * * new data,Becassi60SI2MN alloy round steel, in September , China s imported iron ore * * * broke through the million ton mark, reaching million tons, a record high; From January to September, and the annual import volume is expected to exceed billion tons. However, judging from the shipment of imported ores after the National Day,Becassi6061 aluminum bar, due to the rapid declinecline in iron ore prices,BecassiSquare aluminum tube, 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.For small diameter pipes when using filler metal, the length of filler metal is allowed to be equal to the diameter of the pipe, which is enough to fill the weld crater. One of the five major application fields of red coppr plate T, red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries, switches and printed circuit boards; In the manufacture of machinery and transport vehicles motors and transformers, it is used to manufacture industrial valves and accessories, instruments, sliding bearings, molds, heat exchangers, pumps, etc.Becassi,{} The copper pipe welding can be divided into soft welding and hard welding. The soft welding temperature is lower than ℃, and the hard welding temperature is higher than ℃. Hard welding is usually used for silver, gold, steel, copper and other metals. Its welding points are much stronger than soft welding, and its shear strength is - times that of soft welding.The excellent performance of copper pipe The copper pipe has the characteristics of and, which makes it a suitable choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial housing.Grand Gorica, we should properly keep the copper products we buy, extend the service life of copper and ensure its performance to avoid unnecessary losses.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, 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.

Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand, according to the new statistics of * *, the available days of imported iron ore of steel mills are days, which is one day lower than that before the National Day, and is on the high side of history. The steel mill said that at present, the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction, the steel mill is not willing to replenish the inventory.Finished products must be stored indoors. During storage, transportation and loading and unloading of copper tubes, rain should be avoided; In summer, the ambient temperature of copper pipe is high, and the speed of copper pipe surface is accelerated. When storing copper pipe, pay attention to the principle of first in first out to reduce no loss; The copper pipe loading process is better carried out indoors to avoid the copper pipe being exposed to the sun, so as to accelerate the speed of the outer wall of the copper pipe. After the loading is completed, at least two layers of canvas shall be used to tightly wrap the whole vehicle materials; After loading, if the truck can not depart in time, the truck shall be driven to the back of the sun to prevent the goods from being exposed to the sun for a long time to absorb heat.Save materials and total cost, stability and performance, and can save maintenance.How much does it cost?,The market opened today. Although the performance of Zitong Pai futures was modest, 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 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, and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature, the market was bleak.On November , the market price of Cangzhou copper bar was stable. According to the monitoring data of Lange Iron and Steel s cloud business platform, the market price of * mm cold drawn steel produced in Linyi is yuan, the market price of * mm in Linyi is yuan, the market price of * mm in Jianlong is yuan, the market price of * mm in Yuanhua is yuan the market price of * mm in Juneng is yuan, the market price of * mm in Baotou Steel is yuan, and the market price of * mm in Juneng thermal expansion is yuan.After the pipe is cleaned the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately, so that dust and dirt will not pollute the capillary gap.

In August, the price of domestic medium and heavy plates fell sharply. As of August , the price center of ordinary carbon boards in leading cities had dropped to down yuan/ton from the end of July. At the beginning of the month, affected by the macro bad news, and the recent poor performance of fundamentals, the market mentality turned to pessimism, and some traders shipped at low prices. The market inventory rose, the inventory pressure was high, the stock shortage phenomenon disappeared, and the market transaction atmosphere was cold, the demand performance continued to decline, and the spot price fell under pressure.Promotion,I don t know how to keep the copper tube.Brass tube Soft copper tube is called hose, and the tube is used to replace the hard one, so soft copper is widely used. Besides being in a straight line, you can also have coils and coils in the form of long advantages. When used at the connection point is long, cut according to the free length, so as to avoid leakage of copper tube brass welding. Soft copper tube requires local bending of air conditioner refrigerator, and mechanical oil tube.pper tube Copper tube is easy to heat because of its light weight, and it can also be used normally at low temperatures.It is mainly used to manufacture electrical devices such as generators, buses, cables, switchgear, transformers, and thermal conductive devices such as flat plate collectors for heat exchangers, pipes, and solar heating equipment. Common copper alloys are divided into three categories: brass, bronze and white copper. Pure copper plate is a purplish red metal, commonly known as & quot; copper plate& quot;, & amp; quot; red copper plate& quot; or & quot; red copper plate& quot;.Becassi,Save materials and total cost, stability and performance, and can save maintenance.In the morning trading today, 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 , down yuan from yesterday. Futures prices fluctuated, 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 make the copper surface become bright again, you can polish it with copper point solution. It can not only make the copper surface brighter, but also quickly remove the rust and oxide layer on the copper surface to restore the luster of the copper itself.
