동관은 수도관， 난방관， 냉동관을 설치하는 것이 가장 좋은 특징을 가지고 있다.
The price of pig iron market rose by - yuan this week， and the transaction was fair. With the increase of coke price， the cost of ductile iron in Shanxi， Henan， Liaoning， Shandong and other regions has increased. In addition， with the gradual release of downstream demand， the inventory of iron plants is not large， and iron plants have successively raised their prices. There are few iron foundries in Shandong， Jiangsu， Hebei and Shanxi， and the inventory remains low. As the coke price rises and the cost increases， the price of iron foundries rises again.
시냇물 이 우당탕 하 다.To prevent the copper pipe surface， the humidity of the packaging materials should be well controlled， and the moisture content of all wood and paper packaging materials should be strictly controlled below %. Each plate of material is tightly packed with PE film to avoid the copper pipe absorbing moisture from the outside.
On the other hand， in the steel plant， the lock price of the steel plant has been falling all the time， and the order receiving is poor. The capacity utilization rate of the steel plant is low， but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising， so the market price has fallen sharply. Subsequently， the futures market rebounded in a wave， and the spot price also increased with the increase. There was an instant of large volume of transactions. However， with the decline of black futures， the market transaction volume shrank significantly. In addition， the inventory pressure was high， traders shipped at low prices， the drop amplitude and rate are less than those of threads.

그러나 단기간에 이런 상황을 바꾸기는 어렵다.당분간 국내 대강 가격이 주로 오를 것으로 예상된다.당산철강그룹유한공사는 이윤 추구를 위해 현재 열판관 공급을 늘리고 있는 것으로 알려졌다.앞으로 더 많은 제철소가 이윤을 추구하거나 하락의 위험을 묻는 경향이 있을 가능성도 배제할 수 없다.내일로 말하자면， 가격은 여전히 좁은 폭의 진동 운행 구도를 유지할 수 있다.
Advantages of red copper tube Durability: copper has stable chemical properties， integrating cold resistance， heat resistance pressure resistance， and can be used in different environments for a long time.
단점: 조직이 느슨하고 고압에 강하기 때문에 이 파이프는 소형 에어컨 동봉 생산에만 사용된다.
PH가 낮은 물은 부식을 일으킬 수 있다.
Red copper inventory in key areas has risen continuously corrosion resistance and fire resistance， but the total pressure is not big. From the current overall inventory situation of the main distribution centers Wuan， Jiangyin and Lecong， the inventory level remains relatively moderate， and the pressure on the market is relatively small. In Wuan market according to the data， the total inventory of medium and thick plates in Wuan was close to tons as of May ， increasing by tons on a weekly basis. In late April， it reached tons lower in the year， down tons from the high level after the Spring Festival， and rose for three consecutive weeks. In terms of the ovquantity it should be said to maintain a relatively moderate level.
도매상The material of the water separator is the same， the expansion coefficient is the same， the cost of the floor heating system is higher.
Among the three production methods of copper tube，시냇물 이 우당탕 하 다.황동판， the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material， the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time， but also has a mature technology， which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.
To sum up， the market in Northeast China is generally pessimistic based on the medium and long-term policies and the general environment，시냇물 이 우당탕 하 다.Q345D 합금 원강， as well as the current inventory level in Shenyang. The low inventory level of copper platoon makes the whole market lack of motivation. The copper bar market in this city has stopped this year， and it is hard to improve in the short and medium term. On the whole， the market price of Shenyang copper bars may be stable tomorrow.
For small diameter pipes， when using filler metal， the length of filler metal is allowed to be equal to the diameter of the pipe， which is enough to fill the weld crater. One of the five major application fields of red coppr plate T， red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries， accounting for more than half of the total consumption. Used for various cables and wires， motors and transformers， switches and printed circuit boards; In the manufacture of machinery and transport vehicles， it is used to manufacture industrial valves and accessories， instruments，시냇물 이 우당탕 하 다.316L 스테인리스 스틸 롤러， sliding bearings， molds， heat exchangers， pumps， etc.
특혜장점: 품질이 좋고 구조가 정교하며 밀도가 높고 내압성이 높으며 구부러지고 변형이 크며 빈번한 냉열교환에 적합하고 작업환경의 온도차가 크며 큰 사이즈의 동관을 생산할 수 있다.

It is said that due to the optimistic future and tight resources， some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well， and the price of raw materials has risen， so the iron price has risen. The iron mills have a high enthusiasm for producing steel， so there is not much cast iron resources， and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting， and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand， 비록 공장이 출하량이 보통이라고 피드백했지만， 시장 재고가 많지 않으며， 공장도 큰 폭의 가격 인하를 원하지 않는다.시장면에서 대강거래는 기타 강재품종보다 우월하며 하류는 주로 회수매입을 위주로 하며 공포성재고정리가 없다.이로부터 알수 있는바 강재시장이 지속적으로 요동치고있지만 대강의 전반 수요는 여전히 량호한 상태를 유지하고있다.
Disadvantages of copper pipe As far as copper pipe is concerned， high production cost and high price are its biggest disadvantages. Compared with other pipe fittings， the cost of copper pipe is much higher， and the connection at the copper pipe interface requires high construction technology level.
또 다른 집산지인 강음시장에서 현재 유통단계의 전체 재고는 약 만 톤으로 정상 수준보다 약간 낮다.이번 주 초 강음 가격과 북방 가격 간의 가격 격차도 약간 낮은 유통 재고에 대응했다.그러나 제철소 정책항을 보면， 남강， 항윤， 다다 등 전체 생산 상황은 비교적 정상이며， 후기 자원량은 안정을 유지한다.락종시장의 전반 재고는 만~만톤 좌우를 유지하여 중등정상수준에 속하며 최근 락종시장의 현물가격은 북방과 비교적 큰 차이가 있다.
