When welding， just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.
It is mainly used to manufacture electrical devices such as generators， buses，아 리 바 르 북부스테인리스강 권재， cables， switchgear， and thermal conductive devices such as flat plate collectors for heat exchangers， pipes， and solar heating equipment. Common copper alloys are divided into three categories: brass， bronze and white copper. Pure copper plate is a purplish red metal， commonly known as "copper plate"， "red copper plate" or "red copper plate".
아 리 바 르 북부Copper pipes of different models shall be stacked separately.
Disadvantages: low output， high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation， which is the development direction of copper tube industry in the future.
살 리 나 스동관의 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.
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，아 리 바 르 북부빨간 동봉， the northern market has entered the off-season of demand， and the markets expectation of future demand is pessimistic. In the short term， 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 * * *.
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.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
구리 파이프는 가공과 연결이 쉽기 때문에 재료와 총 비용， 안정성 및 신뢰성을 절약할 수 있으며 설치 과정에서 유지 보수를 절약할 수 있습니다.
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?

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.
아 리 바 르 북부The market price of Zhengzhou copper bars is basically stable，아 리 바 르 북부T2 동갈비， and the shipment is not good. In terms of tube blank: today， Shandong Luli tube blank slightly reduced by yuan， and the current mainstream ex factory price is - yuan. In terms of pipe plant: Linyi Pipe Plant locked the price for a week. With a stable market mentality， the factory price of hot rolled seamless pipes is now between - yuan. On the market side: with the arrival of the off-season， traders generally ship goods at a high price. Replenishment is mainly to maintain the existing inventory， and there is no large replenishment plan. The demand is sluggish and the market price of Zhengzhou copper bar is expected to be stable and declining.
Safe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals， has good toughness and high ductility， and has excellent anti vibration anti impact and anti frost expansion properties.
I dont know how to keep the copper tube.
