Copper pipe has the characteristics of， and is the choice for the installation of water pipe， heat supply and refrigeration pipe.
동관은 일종의 비철금속관으로서 압제하고 늘어나는 무봉관이다.동관은 열전도성이 뛰어나고 견고하며 부식에 강하다.환경 온도에 비해 갈라지지 않기 때문에 모든 주택 분양주택에 수도관， 난방관， 냉동관을 설치하는 것이 현대 하청업체의 우선순위가 되었다.
오 스 트 송 드ased copper tube is made of oxygen free copper rod， which has good processing characteristics and can be punched， bent and other process design requirements. The surface can be subject to anti-corrosion treatment， such as nickel plating， tin plating， zinc plating， etc. The surface anti-corrosion can reach hours of fog test. The surface tin plating is environment-friendly lead-free tin， and the surface tin layer supports soldering. T degreased copper tube is mainly used for communication cabinet， transformer， charging pile， box type substation and other electrical facilities. The copper bar is harder than the plastic pipe and has the degree of common metal (the strength of the cold drawn degreased copper pipe is equivalent to that of the steel pipe with the same wall thickness). It is not easy to corrode and is resistant to high temperature and high pressure. It can be used in various applications. The main material of copper bar is copper. The melting point of copper is as high as ℃， so as long as it is used correctly，오 스 트 송 드7075 알루미늄 튜브， there is no need to worry about safety. When choosing to decorate the house， few people ask about the water supply pipe of the house. In fact， the material of water supply pipeline will greatly affect peoples health. T copper tube has strong capacity. Escherichia coli in the water supply will not continue to breed in the degreased copper tube， and more than % of the water will disappear after entering the degreased copper tube for hours. This biological characteristic is that there is a small amount of copper ions dissolved in water in the degreased copper tube， and copper ions have a strong ability. Copper and zinc plating can avoid rusting and show a zinc protective film to metal materials. The conductive metal material repair and color enhancement care agent I can generate the thickness of the metal material epoxy protection layer and the pipelincathodic protection layer， which can resist extreme weather and is suitable for the long-term surface of metal materials. The actual effect of salt and water corrosion resistance is good. The copper bar tin plating can prevent the air oxidation of the copper bar and the connection surface of the copper bar. In addition， the melting of metal tin and copper will produce aluminum alloy which will improve the adhesion of copper strip coating. In addition， the conductivity of metal tin is good. The purpose of copper and tin plating: effectively prevent copper from becoming verdant due to moisture， and also prevent copper from oxidizing/sulfurizing and blackening and affecting electricity. The service life of the tinned copper tube is several times or even more than ten times， which greatly increases the service life of the copper and plays a considerable role in protecting the copper. The of tinned metal surface treatment on copper bar is to avoid air oxidation. As the air in industrial production air， marine climate or cold air is easy to turn black or produce copper green when oxidized， the copper bar surface shall be tinned for the total area， the demand for plastic coated copper tubes is gradually increasing. Then how to apply wood grain paint on alloy pipes. Wood like paint is a kind of wood like paint. It is used for spraying plastic coated copper pipe and its process flow. Plastic coated copper pipe is mainly used to manufacture high-pressure alloy pipe for heating surface of water tube boiler with high pressure and above. In the morning market， the mainstream spot price quoted by Lianzhong was - yuan/ton， and the tax inclusive base price quoted by Hongwang and Chengde was - yuan/ton. On a month on month basis， part of the producing areas recalled yuan， and the mainstream tax inclusive base price in the market changed from strongeak in the - plastic coated copper pipe supply and demand relationship. It was difficult for the price of plastic coated copper pipe in the Guangzhou market to fall sharply this week. Second， headers and main steam ducts of domestic HP， UHP and subcritical power plant boilers. Third， large diameter pipes are mainly used as headers and main steam pipes with steam parameters below ℃.
Five of the five major application fields of copper plate， copper bar and copper tube: copper is used in medicine. In the s， Chinese medical inventors Liu Tongqing and Liu Tongle found that copper has extremely strong s， and successfully developed the corresponding "Cancer Suppressing "， which is successful in the near future.

Although the opening continued the weak trend， the intraday transactions improved， although the manufacturer feedback that the shipment is average，오 스 트 송 드45# 원강， 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.
구리 자체의 특성으로， 환경 습도가 높은 곳에서는 녹이 슬고 부식되기 쉽다.습도우리가 자주 사용하는 경우 문제가 더 적지만 오래 두면 구리가 손상됩니다.많은 사람들이 구리 표면을 어떻게 처리하는지 모릅니까?이제 직원이 답변해 드리겠습니다.
Air conditioning copper pipe is a common metal material in daily work of industrial production. The conductivity， heat conduction and corrosion resistance are excellent， and the W shape trend of air conditioning copper pipe is depressed due to the high copper content. Good machinability fusion welding and brazing are very good. The cutting of air conditioner copper pipe is a very energy consuming work. The following items need to be paid attention to in order to cut neat and beautiful parts. Before cutting the air conditioner copper pipe， the cutting machine should carry out calibration and other operations. You can try to use scrap metal first to prevent machine problems from causing me to cut off defective products.
Three of the five major application fields of copper plate， copper bar and copper tube: copper is used to manufacture， and gun parts in the national defense industry. Every million rounds of copper are produced， - tons of copper are needed.

Red copper inventory in key areas has risen continuously， 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， as of May ， the total inventory of medium and thick plates in Wuan was close to tons， increasing by tons on a weekly basis. In late April，오 스 트 송 드5052 알루미늄 바， 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.
I dont know how to keep the copper tube.
Four of the five major application fields of copper plate， copper bar and copper pipe: copper is used as various pipes， fine structure， high pressure resistance， large bending deformation， suitable for frequent cold and heat exchange， large temperature difference in working environment， and large size copper tube can be produced.
The evaporated zinc is immediately turned into zinc in the air， forming white smoke， which brings great difficulties to the operation and affects the health of welders. Therefore， in the places where decorative brass pipes are welded， ventilation and other protective measures should be strengthened. The poor weldability of brass will cause problems such as pores， cracks， zinc evaporation and so on.
Generally， oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.
오 스 트 송 드동관의 단점은 동관의 경우 높은 생산 원가와 높은 가격이 가장 큰 단점이다.다른 파이프 부품에 비해 구리 파이프의 원가가 훨씬 높고 구리 파이프 인터페이스의 연결은 비교적 높은 시공 기술 수준을 요구한다.
However， it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits， Tangshan Iron and Steel Group Co.， Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits， or to lay hidden dangers for the decline. As far as tomorrow is concerned， the price may still maintain a narrow range of shock operation pattern.
