장점: 품질이 좋고 구조가 정교하며 밀도가 높고 내압성이 높으며 구부러지고 변형이 크며 빈번한 냉열교환에 적합하고 작업환경의 온도차가 크며 큰 사이즈의 동관을 생산할 수 있다.

동관 연결의 견고성이 강하다: 동관과 동관 부품의 연결이 견고하다.

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.
경동관은 신축이나 압출 후 인공 처리를 거치지 않아 자연적으로 형성될 수 있다.이제 구리 파이프의 조직 형태가 가득 찼습니다.이런 동관은 갈라지기 쉬워서 구부리기에 적합하지 않다.그러므로 경동관은 일반적으로 곧다.
In consideration of the above factors， 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，부탄.304 스테인리스 강판， the quantity of * * * is relatively limited. In general， the short-term iron ore market may lack upward momentum.
서로 다른 모델의 동관은 따로 쌓아야 한다.
Overview of three production methods of copper tube Copper tube is a very important material for copper materials. There are many ways to complete the production of this copper tube. For copper pipes， the following three methods are generally used to produce materials. The copper tubes produced by these three methods are not only very good in performance， but also very convenient to operate. There are three production methods for copper tube， so what are the three production methods for copper tube?
설치 하 다.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， steel mills in some regions began to implement the production restriction measures for blast furnaces in heating season， 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.

However， it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits， Tangshan Iron and Steel Group Co.， Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits，부탄.알루미늄 청동판， or to lay hidden dangers for the decline. As far as tomorrow is concerned， the price may still maintain a narrow range of shock operation pattern.
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.
어디 에 있 느 냐Generally， oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.
First of all，부탄.310s 스테인리스강 원강， brass pipe is a non-ferrous metal pipe， which can generally be used as a water pipe. Because this pipe product is a seamless product， because this kind of copper tube product has its own hardness and good corrosion resistance， it can also be used as heating and cooling tubes. The brass tube not only has good corrosion resistance and hardness， but also has strong plasticity. Compared with other metal pipe products， this kind of pipe has the characteristics of bending inversion， and not easy to break. This kind of pipe product is widely used in daily life and has a longer service life.Brass pipes have strong frost heave resistance and impact resistance. Copper pipe products with these advantages have a long service life and can play an important role in building water supply systems. In short， as long as this copper tube product is installed， it is safe and reliable， and even does not need maintenance.
The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， the elongation is ~%， and the Brinell hardness (HB) is ~

When stacking， it shall be stacked reasonably and placed first.
