Four of the five major application fields of copper plate， copper bar and copper pipe: copper is used as various pipes， pipe fittings and decorative devices in the construction industry.
수분 분리기는 재료가 같고 팽창 계수가 같아 수분 분리기와의 연결이 잘 새지 않는다.적용 범위: 구리 파이프가 플라스틱 파이프보다 비싸기 때문에 난방 시스템의 비용이 더 높습니다.
모 고.Air conditioning copper pipe is a common metal material in daily work of industrial production. The conductivity，모 고.2507 스테인리스 강판， 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， 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.
The simplest way is to use copper cleaner. Brass， red copper， bronze， etc. can be used. Oil stains， fingerprints，모 고.321 스테인리스강 원강， oxide layers， etc. on the surface can be cleaned with copper cleaner first.
브 루 데 이If the corrosion on the copper surface is found to be slight， but it is not recommended to apply oil for preservation.
At present， the fundamentals faced by the domestic copper bar market are still mixed. On the one hand， the market supply is expected to shrink， but on the other hand， the northern market has entered the off-season of demand， and the markets expectation of future demand is pessimistic. In the short term， domestic steel prices will enter the operating track of range consolidation. To sum up， considering the current situation of demand and inventory in the steel market， it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching， environmental protection phenomena such as steel mills are still going on， and black series speculation is still taking place. But personally， the fluuation range of the market in this region is limited， and businesses can operate flexibly on a short-term basis， and the shipment transaction is * * *.

Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe， characterized by light weight， good thermal conductivity high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes， the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?
Remove the flame. If the filler metal does not melt， continue to heat the joint and try again. The melted filler metal is sucked into the casing port according to the capillary effect until a complete filler metal ring appears on the casing port. Remove the flame Pay special attention not to let the flame directly contact the filler metal. It should be the heat at the joint that melts the filler metal. In order to clean the copper pipe， the welding flux must have a degree of corrosivity， and shall be cleaned after brazing. The so-called "self-cleaning" fluxes are generally not recommended because of their corrosivity.

Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand， the continuous decline of iron ore port inventory may end. In addition， according to the new statistics of * *， which is one day lower than that before the National Day， and is on the high side of history. The steel mill said that at present the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction， the steel mill is not willing to replenish the inventory.
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， 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.
