The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm， yuan for Ruigang Lianlian， yuan for Baoda yuan， yuan for Meixin yuan， and yuan for Taizong yuan.
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 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.
사 우 닐 다 니 아How to preserve the copper tube? In order to protect the excellent performance of copper pipes from the impact of the environment， we need to do the following: First select appropriate sites and warehouses， and keep the surrounding environment dry and ventilated. Do not stack together with acid， alkali， cement， etc.

In the morning trading today， the price of domestic copper bar fell. According to the monitoring data of Lange Steels cloud business platform， the average price of * mm hot rolled strip in key cities in China is ， 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.
설비 유지 보수장 & # ;우리는 동관 재료의 장점을 상세히 서술했다: 동관 지온은 뜨거운 물을 열매체로 이용하여 동관 가열관에서 순환하고 바닥을 가열하며， 지면을 통해 복사와 대류 전열 방식으로 바닥을 가열하는 일종의 가열 방법을 말한다.. 동관은 열을 방출하는 효과가 빠르고 내열성이 강하다.고온으로 물을 공급하는 상황에서도 지온관의 사용 수명은 영향을 받지 않는다.둘동관은 금속관이고，o 잘 안 긁혀요.따라서 누설은 쉽지 않다.셋고온에 강하고 고압에 강하며 어떤 일반 플라스틱 파이프에 비해도.동관 바닥은 따뜻하고 고온과 고압에 강하다.사수명이 길다.다섯
동관의 전기 전도 생산은 이런 방법의 최신 방법이다.그것은 전도성을 가진 나노 결정 구리 재료의 생산이다.이 원재료는 매우 특수하기 때문에 나노기술을 이용하여 생산되는 구리 재료로 구리 이온은 전도성을 통해 분리될 수 있기 때문에 분리된 구리 이온으로 구리 파이프를 생산할 수 있다.이런 방법은 매우 복잡하고 첨단기술과 새로운 설비가 필요하기에 국외선진국만이 이런 생산방법을 사용할수 있다.
Later， Mexican scientists also found that copper has a . Recently， British researchers found that copper has a strong bactericidal effect. It is believed that in the near future copper will make great contributions to improving human health. Copper plate T is named after its purple color. It is not necessarily pure copper， sometimes it also involves a few deoxidizing elements or other elements to improve raw materials and s， so it is also included in copper alloys. The processed materials of Chinese cor plate can be divided into four categories according to the composition: ordinary copper plate (T， T， T， T， oxygen free copper plate (TU， TU and high-purity， vacuum oxygen free copper)， deoxidized copper plate (TUP， TUMn)， and special copper plate (arsenic copper， tellurium copper， and are widely used to manufacture conductive and thermal conductive devices. The red copper belt has outstanding corrosion resistance in the atmosphere，사 우 닐 다 니 아321 스테인리스강 원강， sea water， some non oxidizing acids， alkalis， salt solutions and a variety of organic acids (aic acid， citric acid)， and is used in the chemical industry. In addition， the red copper plate has outstanding weldability and can be made into various semi products and products through cold and thermoplastic processing. In the s， the output value of copper plate exceeded that of other copper alloys.
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.
시장.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.
In addition，사 우 닐 다 니 아304 스테인리스강 원강， 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.
Although the opening continued the weak trend， the intraday transactions improved， and the prices of some copper bar manufacturers rose. From the specific situation， although the manufacturer feedback that the shipment is average， the mentality is relatively calm， the market inventory is not much， and the manufacturer is not willing to significantly reduce the price. In terms of the market， the transaction of strip steel is better than other steel varieties， and the downstream mainly focuses on callback buying without panic inventory clearing. It can be seen that although the steel market continues to shake， the overall demand for strip steel remains in a good state.
