Red copper plate has ductility. Pure copper， which is as big as a drop of water， can be pulled up to two kilometers of thin wire or rolled into a transparent foil larger than a bed. The most valuable property of red copper row is that it has a very good conductive ， second onlyver in common metals. But copper is much cheaper than silver，규 송 시동봉， so it has become the "protagonist" of the electrical industry.
The difference between hard copper tubes and soft copper tubes in use Hard copper tubes can only be used as straight tubes and cannot be bent. Therefore， they are generally used in power plants， switches of electrical equipment， and places where the connection points are far away and do not need to be bent. Compared with soft copper tubes， the price of hard copper tubes will be lower. Although the name of the soft copper tube is soft tube， it can also be used as a hard tube， so the soft copper tube is used in more places， and can be used in a straight tube way asell as in a coiled tube way. The length of the copper tube can be longer if the coil is used. If the connection point is longer， it can be cut randomly according to the length， so as to prevent leakage when welding the copper tube. Soft copper pipes are used in many refrigerators， air conditioners and other places where bending pipes are needed. When we use copper， we need not consider the preservation problem unless we buy a small amount at home. For example， large manufacturers use copper units to buy a large number of copper pipes once， so there will be a problem. I believe some people do not know how to store unused copper materials， Now lets ask our staff to introduce the storage method of copper for you.
규 송 시동관 용접 정밀도가 높고 생산 속도가 빠르며 표면의 광결도가 좋고 외형이 아름답다.따라서 유리， 철물， 전자， 부품， 목욕 및 주방 기구와 같은 정밀 용접 산업에 널리 사용됩니다.
The production method of soft copper tube is basically the same as that of hard copper tube， that is， 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.
아 로 코동관의 응용 동관은 일반적으로 환열 설비에 사용되며， 산소 제조 설비의 저온 파이프도 사용할 수 있다.비교적 얇은 일부 동관은 일부 가압액체를 수송하는데 사용할수도 있고 계기중의 압력측정관으로 사용할수도 있다.또한 구리 파이프는 다른 금속과 달리 상대적으로 견고하고 쉽게 부식되기 때문에 현재 많은 건물에서 사용되는 수도관과 냉동 파이프는 구리 파이프를 사용합니다.
Because of the characteristics of copper itself， the problem will be smaller， but if it is placed for a long time， the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.
Tangshan billets rose sharply last weekend， steel mills in some northern cities implemented production restriction， and some domestic economic data improved， which boosted manufacturers confidence. Today， steel prices generally rose. However with the approaching meeting and the rainfall in the south caused by the typhoon， the construction progress of the downstream construction site is affected， which is not conducive to the continuous demand. The high spot price transaction today is weak，규 송 시붉은 동관， which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow， and some businesses may reduce prices and take goods.
구리 표면의 부식이 경미한 것으로 발견되면 리넨 동선으로 지울 수 있지만 기름을 발라 방부하는 것은 권장되지 않는다.
Reasons for copper pipe corrosion: Air pollution.
[] Welding process of copper pipe Clean the end and seven ports of steel pipe with steel wool. Do not use abrasive cloth or abrasive paper to clean， because it will affect the clean interface and result in poor welding effect.
품질 이 좋다요약하면， 중장기 정책과 대환경 및 선양의 현재 재고 수준에 근거하여 동북지역 시장은 보편적으로 비관적이다.구리 배출의 낮은 재고 수준은 전체 시장을 동력이 부족하게 한다.본 시의 동봉시장은 올해 이미 멈추어 단기와 중기 내에 개선하기 어렵다.총체적으로 볼 때 래일 심양의 동봉의 시장가격은 안정될수 있다.
동관의 세 가지 생산 방법은 동관이 동재료의 매우 중요한 재료라는 것을 개술한다.이런 동관의 생산을 완성할 수 있는 많은 방법이 있다.구리 파이프의 경우 일반적으로 다음 세 가지 방법을 사용하여 재료를 생산합니다.이 세 가지 방법으로 생산된 동관은 성능이 매우 좋을 뿐만 아니라 조작도 매우 편리하다.동관은 세 가지 생산 방법이 있는데 동관의 세 가지 생산 방식은 무엇입니까?
동관의 세 가지 생산 방법 중에서 산화법이 가장 많다.금속 구리가 양극에 의해 산화되고 양극의 구리 이온이 관 재료에 부착되면 구리 관을 생산할 수 있기 때문이다.여기방법도 구리 재료를 생산하는 가장 상용하는 방법이다.그것은 오랫동안 사용되었을 뿐만 아니라 산화 반응을 통해 구리 파이프를 생산하는 성숙한 기술이 있습니다.이런 생산 방법은 중국 동관의 주요 생산 방법이다.
동판， 동봉， 동관의 다섯 가지 주요 응용 분야 중 다섯 가지: 동은 의약에 쓰인다.세기 년대에 중국 의학 발명가 류퉁칭과 류퉁러는 구리가 매우 강한 s를 가지고 있음을 발견하고 해당하는 &를 개발하는 데 성공했다.quot；암 억제 및;“；， but the local resources are tight， Shandong resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu， Shanxi， Hebei， Henan and other regions is sluggish， and the inventory pressure of iron mills is increasing. As the price of raw materials decreases， the quotation of iron mills continues to decline. At present， the demand and cost support are weak， and there is no positive boost. The short-term pig iron market is weak and difficult to change.antages: 낮은 생산 비용과 높은 생산성.
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， 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， a basic metal product has remained weak.
Red copper bars in other regions basically follow the price trend of Tangshan， in which the bid of Jiangsu Steel Works tends to be higher， and most of the downstream prices are asked， and the overall market transaction is fair. The steel mills in Wuan are limited in receiving orders， and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary， and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak， so they hold a cautious wait-and-see attitude. At prepresent， the steel market is in the "golden third" peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.
규 송 시The 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.
가장 간단한 방법은 구리 세정제를 사용하는 것이다.황동， 자동， 청동 등을 사용할 수 있다.표면의 기름때， 지문， 산화층 등은 먼저 구리 세정제로 세척할 수 있다.
Copper tube is a kind of nonferrous metal tube， which is pressed and drawn seamless tube. The copper pipe has good thermal conductivity， and is solid and corrosion resistant. It will not crack when compared with the ambient temperature， so it becomes the first choice for modern contractors to install the water pipe heat supply pipe and refrigeration pipe in all residential commercial houses.
