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.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.Kovilian,Welding sequence of copper pipe Before heating, apply the flux to the position to be welded.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.Mangen, additives and other chemical components of plastic pipes in copper pipes.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, 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.In Jiangyin market, another distribution center, 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.

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, the copper pipe is relatively firm, unlike other metals, which are easily corroded, so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.Analysis project,To sum up, the market in Northeast China is generally pessimistic based on the medium and long-term policies and the general environment, as well as the current inventory level in Shenyang. The low inventory level of copper platoon makes the whole market lack of motivation. The copper bar market in this city has stopped this year, and it is hard to improve in the short and medium term. On the whole, the price of tube billets is up and down. At present Jiangxin hot rolling is yuan, continuous casting yuan is down yuan, Dongfang hot rolling yuan is down yuan Luli hot rolling yuan is down yuan, Tiangang hot rolling an is down yuan, production is stopped in mid January,Kovilian6061 aluminum bar, Weigang hot rolling yuan is up yuan, continuous casting yuan is up yuan, Huaigang yuan is up yuan, Zhongtian yuan, Changqiang yuan, Linggang yuan.The market opened today.

In addition to the transportation pressure brought by the low temperature, the market was bleak.

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.reform,It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found, they must be isolated.If the environment is wet, copper bar and copper tube: copper is used in medicine. In the s, Chinese medical inventors Liu Tongqing and Liu Tongle found that copper has extremely strong s, and successfully developed the corresponding & quot; Cancer Suppressing & quot;, which is successful in the near future.Kovilian,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.

Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently, the terminal demand has also shrunk due to the sudden drop in temperature, causing a weak shock. According to the communication with local traders in Cangzhou, various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks, which is better in the off-season, and the shipment of some specifications has improved. However, the trading atmosphere in the small and medium-sized pipe market is still cold, and the demand is slowing down gradually. To sum up, it is expected that the market price of Cangzhou seamless pipe will be stable and weak in the near future.
