동관은 동관， 비철금속관이라고도 한다.그것은 일종의 압라무봉관으로 무게가 가볍고 열전도성이 좋으며 저온강도가 높고 부식에 견디는 등 특징을 갖고있다.동관은 이런 우수한 재산을 가지고 있기 때문에，니 바라T2 동판，니 바라321 스테인리스강 권재， 동관의 사용은 매우 보편적이다.경동관과 연동관은 사용 과정에서 어떤 차이가 있습니까?양자는 구체적인 응용 방면에서 어떤 차이가 있습니까?
The production method of soft copper tube is basically the same as that of hard copper tube， that is， the annealing process is added compared with the hard copper tube. Annealing of copper tubes means that they are calcined in a high temperature furnace to change the arrangement of the elements in the copper tubes. However， 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.
니 바라For the deposited copper tubes， do not open the outer packaging as much as possible.
At 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.
몬 테 카 포The 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.
동봉시장은 이번 주에 안정적으로 하락하여 하락폭이 ~원이다.생철 재고가 비교적 낮기 때문에， 장시의 일부 제철소는 최근 이미 구매를 재개했지만， 구매량은 크지 않다.전기 양철 구매 가격이 비교적 낮기 때문에， 구매량을 확보하기 위해 윈난 제철소의 양철 구매 가격은 약간 인상되었다.최근 강재 시장은 줄곧 흔들리고 조정 중이어서 상인들이 불안정하다.허베이， 톈진 및 기타 지역의 제철소는 이미 제강용 생철 생산을 중단했다.지금은 주로 조사가 이뤄질 것으로 보인다.그러나 원자재 가격이 낮기 때문에 제철소의 가격은 이미 인하되었다.
상술한 바를 종합하면， 현재 현물 시장 가격이 상인들이 예상한 겨울 창고 저장 가격보다 훨씬 높은 등 요소의 영향으로철광석 가격이 상승함에 따라 철광석 가격지수는 한때 달러 아래로 떨어져 수입 광석의 출하 열기를 떨어뜨렸다.이밖에 환경보호검사가 더욱 엄격해져 일부 국내광산의 공급이 큰 영향을 받았다.현재 국내 광산의 가동률은 이전 최고치보다 % 포인트 낮아 앞으로 더 떨어질 것으로 보인다.
In view of the current overall price difference， 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， 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.
When cutting the copper pipe of air conditioner， use tools such as clamps to fix the copper bar and then cut it， rather than fixing it by hand， to preveshaking and resulting in irregular cutting. After the cutting of the air conditioner copper pipe is completed， the cut parts need to be placed in a dry place， and then processed again after cooling， otherwise oxidation will occur due to high temperature. Liu Shuchen，니 바라스테인리스강 권재， director of the Resource Analysis Office of the Information Center of the Ministry of Land and Resources， said that copper bar manufacturers are currently in a period of adjustment in Chinas mining industry as a whole. In the long run， the mining super cycle driven by Chinas demand has not changed， especially the growth rate of the countrys economy. After the global economy may improve in the second half of the year， the global mining industry will rise again， and the W-shaped trend will fully emerge. In the second half of the year， there were signs of stabilizing and rebounding. In terms of the macro factors affecting the bulk commodities， the factors affecting the European market of tinned copper bars have gradually weakened， and the economic conditions of China and the United States have become the key factors affecting the bulk commodities. The European economic recession is a foregone conclusion and the possibility of a crisis in the next period of time is also reduced. In recent years， the American market economy has shown the characteristics of better than expected in the first quarter and weaker than expected in the second quarter. Since January， the global price of medical copper tubes has gradually got rid of the main tone of this years shock and decline. "Air conditioning copper tubes show signs of stabilizing and rebounding. The three-month copper on the London Metal Exchange once rebounded nearly % from the years low point， and the market price has rebounded to around dollars per ton. Driven by this， products including aluminum， zinc and other products have also rebounded. Only nickel， has remained weak.

작업 원가단점: 생산량이 낮고 생산 원가가 높으며 가격이 높다.압출 동관 공예는 현재 국내외의 안정적이고 우수한 동관 생산 방법이다.오직 이런 공예로 생산한 동관만이 난방분야에 더욱 적합하며 이는 동관업종의 미래의 발전방향이다.

In addition， it is 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 for many times in other places.
건설 하 다.The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.
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， the coating amount of passivation agent on the copper tube surface is increased. After blanking 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.
The hard copper tube is not artificially treated after being drawn or extruded， so that it can be naturally formed. At this time， the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore， 공공건축， 공업시설 등 장소에서 지온라디에이터를 사용하기 시작하는데 이는 지온의 중요한 구성부분이다.구리의 내식성 때문에 많은 곳에서 구리 파이프를 라디에이터의 주요 재료로 선택한다.
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
In the middle and late ten days， due to the high inventory level， traders had no desire to increase prices， most of them had shipped goods， and spot prices lacked motivation to rise. The market inventory rose significantly. At that time， the market inventory in Handan reached a high level after the festival. The sluggish demand performance for a long time led to the oversupply of the market and the continuous rise of inventory led to the empty market mentality.
