The conductive production of copper tube is the latest method for this method. It is the production of nanocrystalline copper materials with conductivity. Because this raw material is very special， it is a copper material produced by using nanotechnology， and copper ions can be separated by conductivity， requires high technology and new equipment， so only advanced foreign countries can use this production method.
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.
모드 너As the copper pipe is easy to process and connect， it can save materials and total cost， stability and reliability， and can save maintenance during installation.
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.
다트 머 스Copper pipe has the characteristics of， and is the choice for the installation of water pipe， heat supply and refrigeration pipe.
In view of the current overall price difference，모드 너황동판， the local copper bar price continued to rise at a high level today， while the regions outside East China did not show an obvious follow-up trend， and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction， and the price support of copper bar is still strong. However， at present，모드 너냉각 구리 파이프， domestic real estate control is still being tightened. The markets expectation of future demand is weakening， and the markets fear of heights appears after the price rises.Today， the market price of copper bars in Shenyang is stable and the shipment is poor.

요약하면， 중장기 정책과 대환경 및 선양의 현재 재고 수준에 근거하여 동북지역 시장은 보편적으로 비관적이다.구리 배출의 낮은 재고 수준은 전체 시장을 동력이 부족하게 한다.본 시의 동봉시장은 올해 이미 멈추어 단기와 중기 내에 개선하기 어렵다.총체적으로 볼 때 래일 심양의 동봉의 시장가격은 안정될수 있다.

어디 에 있 느 냐At 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.
According to * * new data in September ， Chinas imported iron ore * * * broke through the million ton mark，모드 너304 스테인리스강 원강， reaching million tons， a record high; From January to September， Chinas 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 $， 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， copper bar and copper pipe: copper is used as various pipes， pipe fittings and decorative devices in the construction industry.
The composite method of three production methods of copper tube is also a high-tech production method for this method. It is a copper material containing impurities. Those copper materials， copper alloys and composite copper materials are put together by electrochemical reaction to produce a nanocrystalline copper material， and then the material is purified to produce copper tube materials.
경제 관리The 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.
Regularly inspect and monitor the copper pipe to reduce the loss caused by copper pipe corrosion.

모드 너Extrusion method: This production method is to cast copper ingots after smelting， and the production limit in Wuan and Tangshan heating seasons has been advanced. In addition， the formal implementation of production limit in "+" urban heating seasons after November by steel enterprises， the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high， and the willingness to further replenish the inventory is not strong. In terms of supply， the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection， the quantity of * * * is relatively limited. In general， the short-term iron ore market may lack upward momentum.
