On October , according to the Economic and Information Commission oong Province at the end of September , and all the de capacity equipment had been shut down and withdrawn. On October Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel, the Development and Reform Commission of Handan City released the Plan for Handan City to Eliminate Excess Iron and Steel Capacity. Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.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.Robri,Air conditioning copper tube production technology Upward lead method: This production method is electrolytic copper after copper tube is directly melted.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, so it has become the & quot; protagonist& quot; of the electrical industry.Manjakandriana,Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.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.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, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.

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, which makes it a suitable choice for modern contractors to install the water pipe, heating pipe and refrigeration pipe in all residential commercial houses.Three of the five major application fields of copper plate, 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.resources,I don t know how to keep the copper tube.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.When welding, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.

According to * * new data,Robri310s stainless steel welded pipe, 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,Robri310s stainless steel coil, 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.Interpretation and observation,Safe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals, has good toughness and high ductility, and has excellent anti vibration, anti impact and anti frost expansion properties.For internally threaded tubes with the same inner diameter, the thickness of feus metal is not required for copper tubes.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, the market was mainlysee yesterday, which caused the overall transaction blocked, and the mainstream manufacturers prices fell today.Robri,When welding, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.antages: low production cost and high production efficiency.When placing, and should not be mixed together. The copper surface may have electrolytes, so it will react, especially with other materials such as rubber, which has a large impact.
