다른 한편으로 강철공장에서 강철공장의 잠금가격은 줄곧 하락하고있으며 주문접수상황이 좋지 않다.이 제철소의 생산능력 이용률은 비교적 낮지만， 시장은 여전히 공급이 수요를 초과하고 있다.제철소의 재고와 현물 재고가 모두 상승하고 있다.이에 따라 시장 가격이 크게 떨어졌다.그 후 선물 시장이 반등하자 현물 가격도 따라서 상승했다.순식간에 대량의 거래가 일어났다.그러나 흑색선물이 하락하면서 시장 거래량이 크게 위축됐다.이밖에 재고압력이 크고 무역상들이 저가로 출하하여 현물가격이 압력을 받아 하락하였다.중후판의 낙하 저항력이 강하기 때문에 낙하 폭과 속도는 나사산보다 작다.
antages: low production cost and high production efficiency.
미 에 크Brass tube Soft copper tube is called hose， and the tube is used to replace the hard one， so soft copper is widely used. Besides being in a straight line， you can also have coils and coils in the form of long advantages. When used at the connection point is long， cut according to the free length， so as to avoid leakage of copper tube brass welding. Soft copper tube requires local bending of air conditioner， refrigerator， and mechanical oil tube.pper tube Copper tube is easy to heat because of its light weight， and it can also be used normally at low temperatures.
Advantages: good quality， fine structure， high density， high pressure resistance， large bending deformation， suitable for frequent cold and heat exchange，미 에 크알루미늄 냉동창고， large temperature difference in working environment， and large size copper tube can be produced.

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， which is an important part of ground heating. Due to the corrosion resistance of copper， copper tubes are selected as the main material of radiator in many places.
Advantages of red copper tube Durability: copper has stable chemical properties， integrating cold resistance， heat resistance， pressure resistance， corrosion resistance and fire resistance， and can be used in different environments for a long time.
The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， the elongation is ~%， and the Brinell hardness (HB) is ~
Finished products must be stored indoors. During storage， they should be protected from direct sunlight to the copper tubes. During the transfer， transportation and loading and unloading of copper tubes， rain should be avoided; In summer， the ambient temperature of copper pipe is high， and the speed of copper pipe surface is accelerated. When storing copper pipe， so as to accelerate the speed of the outer wall of the copper pipe. After the loading is completed at least two layers of canvas shall be used to tightly wrap the whole vehicle materials; After loading，미 에 크알루미늄 청동판， if the truck can not depart in time， the truck shall be driven to the back of the sun to prevent the goods from being exposed to the sun for a long time to absorb heat.
The material of the water separator is the same， the expansion coefficient is the same and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe， the cost of the floor heating system is higher.
안전 생산The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.
현재의 전체 가격차를 감안할 때， 오늘 현지 동봉 가격은 계속 높은 수준으로 상승하고 있지만， 화동 지역 이외의 지역은 뚜렷한 후속 추세가 나타나지 않고 있으며， 현지 가격은 여전히 동북과 화중 지역과의 가격차의 우세를 가지고 있다.생산 제한의 영향으로 현지의 후속 상품량이 비교적 적기 때문에， 현지의 재고 압력은 더욱 낮아질 것이며， 동봉 가격의 지탱은 여전히 강하다.그러나 현재 국내 부동산 통제는 여전히 강화되고 있다.시장 & # ;미래의 수요에 대한 시장의 예상이 약화되고 있습니다.오늘 심양 동봉의 시장 가격이 안정되어 출하량이 좋지 않다.
In the morning trading today， the price of domestic copper bar fell. According to the monitoring data of Lange Steels cloud business platform， down yuan from yesterday. Futures prices fluctuated and the prices of spot market manufacturers eased slightly today. According to the feedback， the market was mainlysee yesterday， which caused the overall transaction blocked， and the mainstream manufacturers prices fell today.

입찰 공 고 를 하 다.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.
In addition， it is very strong， not easy to be corroded， and can adapt to various environments. It can be used normally at low and high temperatures， so copper pipes need to be selected many times in other places.The color change on the outer surface of the copper tube is difficult to control due to environmental factors. To prevent moisture absorption on the surface and core of the annealed brass tube， a constant temperature and humidity packaging room can be built. Packaging in the packaging room can avoid the color change on the outer surface of the copper tube. However， it is not easy to control the situation that occurs in the processing process. The cost of ensuring constant temperature and humidity in the whole workshop is too high. The following measures are taken to control the process materials: In the season of high temperature and humidity， during the production and processing of copper tubes， the amount of oil coating on the surface of copper tubes can be increased to form an oil film on the surface of copper tubes， which can isolate water vapor and corrosive gases， and prevent the corrosion of the surface of copper tubes; The humidity in the air at night is high， and the outer surface of the copper pipe is prone to corrosion and discoloration at night. Closing the doors and windows of the workshop at night can make the situation worse; After the coil surface is cleaned in the rewinding process， plastic bags shall be added to the whole support material to further reduce the contact between the copper pipe and the air and prevent the surface of the copper pipe.
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.
미 에 크It 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，미 에 크T2 동갈비， 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 most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand， the pig iron market is performing well and is expected to continue to operate strongly in the short term.
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.
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
