만약 당신이 장기적으로 이런 상황을 피하고 싶다면， 당신은 둔화 처리를 선택할 수 있다.이렇게 하면 구리 표면이 심할 뿐만 아니라 정상적인 상태에서는 청결할 수 있지만 초음파 처리와 침포 처리 후 년 이상 공기 중에 유지하는 것은 큰 문제가 아니기 때문에 이런 효과가 매우 좋다.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
가래나무.구리 파이프는 가공과 연결이 쉽기 때문에 재료와 총 비용， 안정성 및 신뢰성을 절약할 수 있으며 설치 과정에서 유지 보수를 절약할 수 있습니다.
It has excellent conductivity， thermal conductivity， ductility and corrosion resistance.
엘 반 코In August， the price of domestic medium and heavy plates fell sharply. As of August ， the price center of ordinary carbon boards in leading cities had dropped to ， down yuan/ton from the end of July. At the beginning of the month， affected by the macro bad news， and the recent poor performance of fundamentals， the market mentality turned to pessimism， the inventory pressure was high， the stock shortage phenomenon disappeared， and the market transaction atmosphere was cold， the demand performance continued to decline， and the spot price fell under pressure.
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.
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.

The market inventory rose， the inventory pressure was high， the stock shortage phenomenon disappeared，가래나무.201 스테인리스 강판， and the market transaction atmosphere was cold， the demand performance continued to decline， and the spot price fell under pressure.
Try to avoid using radiator copper pipes in hot water circulation pipelines to reduce the possibility of corrosion. If copper pipes are used as circulation pipelines pipeline maintenance space should be reserved.
When stacking， it shall be stacked reasonably and placed first.
소매상안정성: 구리 파이프는 금속 파이프와 비금속 파이프의 장점을 결합합니다.그것은 플라스틱 파이프보다 더 단단하고， 일반 금속의 고강도를 가지고 있다 (동관을 냉발시키는 강도는 같은 경도를 가진 강관과 같다ess）；그것은 일반 금속보다 쉽게 구부러지고 강인성과 높은 확장성을 가지고 있으며 진동， 충격 및 동팽창에 강한 재산을 가지고 있습니다.
With the advent of heating season， the raw material support of red copper row is weak. Under the influence of heating season and environmental protection production restriction， steel mills in some regions began to implement the production restriction measures for blast furnaces in heating season， and the demand for iron ore was weakened. In addition， the production restriction policy was issued in Tangshan today. From : on October to : on October the production restriction measures specified in this Notice were implemented.
If you want to make the copper surface become bright again， you can polish it with copper point solution. It can not only make the copper surface brighter， but also quickly remove the rust and oxide layer on the copper surface to restore the luster of the copper itself.
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.
품질 검사 보고서Although the opening continued the weak trend the intraday transactions improved， and the prices of some copper bar manufacturers rose. From the specific situation， although the manufacturer feedback that the shipment is average， 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， it is often used in some ah heat exchangers to Kazakhstan oxygen equipment.
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.
가래나무.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， 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?
First of all， we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C， while the humidity should be normal. The room should be kept ventilated.
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， so it has become the "protagonist" of the electrical industry.
