I dont know how to keep the copper tube.
세 나 강변 아 넬When 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， otherwise oxidation will occur due to high temperature. Liu Shuchen， 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， especially the growth rate of the countrys economy. After the global economy may improve in the second half of the year the mining super cycle driven by Chinas demand has not changed， 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.
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.

The copper tube shall be heated and welded first， and then the joint shall be heated until the heated part turns dark red. At this time， when the filler metal contacts the tube， 비록 좋은 소식이 있지만， 예를 들면 선물 가격 상승과 무강 생산 제한 정책이 증가한다;한 지역에서는 재고 수준이 매우 높기 때문에 무역상들이 가격을 인상할 의사가 없으며， 그들 중 대다수는 이미 출하되어 현물 가격이 상승할 동력이 부족하다.시장 재고가 대폭 증가하다.당시 한단의 시장 재고는 명절 후에 비교적 높은 수준에 이르렀다.장기간 부진한 수요표현은 시장의 공급이 수요를 초과하고 재고가 지속적으로 상승하여 시장의 심리상태가 공허해졌다.
One oftion of copper tubes. The common wave shape is a single copper tube. Hyperbolic means that two different arcs overlap on the same surface， that is， starting from different circle centers， draw arcs in two radii. The red copper tube is a module made of double curves designed according to the drawings. The red copper tube is light in weight， good in rigidity and high in strength. The shapes of the red copper tubes processed are different and can be processed into various geometric shapes such as arcs and spheres. It is beautiful， elegant and colorful. Lets talk about the two main methods of processing and forming the copper tube: The hot processing and forming method is to roll the copper tube to a roughly hyperbolic shape， then heat it， then place it on the mold prepared in advance， then slowly beat it with a hammer， finally cut， weld， fold， polish and polish it. The whole process needs to be very careful to ensure the surface quality of the copper tube. This forming method is very suitable for parts with small model and large arc change. When the model size is relatively large and complex， it can be considered to break it into small pieces for forming， and then splice it into large pieces. For such copper pipes， the cost is high and the production period is long. Forming method of roll bending This method is to make some modifications on the roll bending machine and change one of the shafts into a concave type and the other into a convex type. This method can form a regular copper tube like a sphere， with a small processing range， but it has great advantages for copper tubes with small radians. What problems should be paid attention to when designing the hyperboloid copper tube? Everyone knows that the design of the air conditioning copper tube is very important. To achieve the beautiful shape， exquisite workmanship and fashionable personality of the hyperboloid copper tube， first of all， the design is very critical. Some small copper tube copanies are not mature enough in design and have not enough design experience， so they often have problems in design， Hyperbolic copper tube is very famous for preparing some details that we should pay attention to in the design. The sculpted copper tube is highly decorative， and the production and processing technology of hyperbolic shaped copper tube is relatively complex. Copper tube products with strong aesthetics. According to the design requirements， different shapes need to be molded for the sculpted copper tube， so the production process of sculpted aluminum veneer is relatively complex.

안전 요구요약하면， 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.
If you want to avoid this kind of situation for a long time， you can choose passivation treatment. In this way， not only is the copper surface serious， it can be cleaned under normal circumstances， but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment， so this effect is very good.
This week (-， the market price of red copper bar rose， and the transaction was not ideal. On the bidding day of Shagang last weekend， and the rising of billets at the weekend drove the market up in a wave， and the price of variety wire rods also rose by yuan at the weekend. However， it was reported that the deal was very poor， which led to the price being stable for the next two days. Until Wednesday， due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving， the market lowered the price. Market price changes， Xinji rose yuan on the rd; For the future market， the off-season is coming， the demand is weakening， and the market wait-and-see mood is getting stronger. But when winter comes， the environmental protection inspection is becoming more and more strict， which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.
The market price of Zhengzhou copper bars is basically stable， 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，세 나 강변 아 넬1060 알루미늄 바， 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.

When the copper tube is heated and the flux melts into liquid， place the preheated electrode on the welding point immediately. As soon as the electrode begins to melt， move the flame nozzle back and forth until the solder flows into the gap between the two tubese the flame， let the solder contact the welding point， and then remove it after a few seconds. If it is suspected or found that there is still a gap between the two pipes. It can be heated again to make the flame nozzle move continuously at two points. A small amount of solder can be added.

The simplest way is to use copper cleaner. Brass， red copper， bronze， etc. can be used. Oil stains， fingerprints， oxide layers， etc. on the surface can be cleaned with copper cleaner first.
