하 이 얼 브라운Under the action of high welding temperature， the evaporation amount of zinc is as high as % during shielded metal arc welding. A large amount of zinc evaporation leads to the decline of mechanical properties and corrosion resistance of welded joints， and also increases the sensitivity to stress corrosion.
동관의 세 가지 생산 방법 중에서 산화법이 가장 많다.금속 구리가 양극에 의해 산화되고 양극의 구리 이온이 관 재료에 부착되면 구리 관을 생산할 수 있기 때문이다.여기방법도 구리 재료를 생산하는 가장 상용하는 방법이다.그것은 오랫동안 사용되었을 뿐만 아니라 산화 반응을 통해 구리 파이프를 생산하는 성숙한 기술이 있습니다.이런 생산 방법은 중국 동관의 주요 생산 방법이다.

Advantages and scope of application of copper tube ground heating At present， ground heating is not only a comfortable heating method， but also a symbol of modern life quality. More and more houses， public buildings， sports facilities， industrial facilities and other places begin to use ground heating radiator， which is an important part of ground heating. Due to the corrosion resistance of copper，하 이 얼 브라운알루미늄판， copper tubes are selected as the main material of radiator in many places.
If you want to avoid this kind of situation for a long time，하 이 얼 브라운310s 스테인리스 스틸 용접관， you can choose passivation treatment. In this way，하 이 얼 브라운316L 스테인리스 파이프， not only is the copper surface serious， it can be cleaned under normal circumstances， but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment， so this effect is very good.
After : on October ， continue to implement the measures of stopping and limiting production specified in TZBZ [] No. document. All sintering machines and shaft furnaces using wet desulphurization in iron and steel enterprises in the city were shut down， and sintering machines using semi dry desulphurization continued to be shut down for %. The access of vehicles is alicted. The port collection and distribution vehicles are prohibited from entering and leaving the port area. The citys steel， coking， electric power， cement， chemical and other key vehicle enterprises are not allowed to transport vehicles into and out of the plant. After : on October ， the vehicle enterprises in the above industries will implement % of the peak load shifting emission reduction measures. It is estimated that the average daily consumption of sintering powder in Tangshan will be more than yuan， and the purchase of iron ore may still maintain a small amount of prudence. In addition due to the influence of industrial users "coal to gas"， in terms of steel plant production the recent performance of coke is weak. Therefore， the support of raw materials is weak.
구리 파이프와 튜브를 가열하여 삽입하고 두 점 사이에서 연속적으로 화염 노즐을 왔다갔다합니다.용접제로 화염에 직접 접촉하지 마라.강관을 가열할 때， 온도는 동관을 가열할 때의 온도보다 약간 높다.
동관 세 가지 생산 방법의 복합법도 이 방법의 하이테크 생산 방법이다.그것은 불순물을 함유한 구리 재료이다.전기 화학 반응을 통해 이러한 구리 재료， and extrude copper tubes by large extruder after secondary heating.

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.
Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand， the continuous decline of iron ore port inventory may end. In addition， 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.

According to * * new data in September ， Chinas imported iron ore * * * broke through the million ton mark， 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 $， environmental protection inspection has become stricter， which is likely to decline further in the future.
The production method of soft copper tube is basically the same as that of hard copper tube， that is， after annealing， the copper tubes will become soft， which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.
