DunakziRed copper barStrengthen industry supervision

The market opened today. Although the performance of Zitong Pai futures was modest the overall market has stopped. The market mentality has not changed much sincekend. The price is stable, 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.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 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 * * *.Dunakzi, rust removal, phosphating and passivationThe 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.Situbondo,Save materials and total cost, stability and performance, and can save maintenance.[] Welding process of copper pipe Clean the end and seven ports of steel pipe with steel wool. Do not use abrasive cloth or abrasive paper to clean, because it will affect the clean interface and result in poor welding effect.With the advent of heating season, the raw material support of red copper row is weak. Under the influence of heating season and environmental protection production restriction, and the demand for iron ore was weakened. In addition, the production restriction policy was issued in Tangshan today. From : on October to : on October , the production restriction measures specified in this Notice were implemented.

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.

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.The copper pipe has high welding precision fast production speed, good surface finish and beautiful appearance. Therefore, it is widely used in precision welding industries such as glasses, hardware, electronics, accessories,DunakziBronze tube, copper bar and copper tube: copper is used to manufacture, and gun parts in the national defense industry. Every million rounds of copper are produced, - tons of copper are needed.property right,Save materials and total cost, stability and performance,Dunakzi40Mn2 alloy steel plate, and can save maintenance.The second of the five application fields of red copper plate T, red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels, distillation pots, brewing pots, etc.According to * * new data, in September , China s imported iron ore * * * broke through the million ton mark, reaching million tons, a record high; From January to September, China s iron ore import increased by % to million tons, and the annual import volume is expected to exceed billion tons. However, judging from the shipment of imported ores after the National Day, due to the rapid declinecline in iron ore prices, the iron ore price index once fell below $,Dunakzi15CRMO alloy plate, 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.

The copper tube shall be heated and welded first, and then the joint shall be heated until the heated part turns dark red. At this time, when the filler metal contacts the tube, the filler metal shall melt.Welcome calls ,It has excellent conductivity, thermal conductivity, ductility and corrosion resistance.In order to solve these problems silicon containing welding wires are commonly used in welding, because silicon will form a layer of dense silicon film on the surface of the molten pool, which will hinder the evaporation of zinc and prevent the invasion of hydrogen.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.Dunakzi, 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.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.
