In addition， it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures， so copper pipes need to be selected for many times in other places.
포 탈 람단점: 파이프 구조가 느슨하고 고압에 약하다.그것은 소형 에어컨 동관 생산에만 적용된다.
In the middle and late ten days， although there were good news such as the rise of futures and the increase of production restriction policy in Wuan region， due to the high inventory level， traders had no desire to increase prices， most of them had shipped goods， and spot prices lacked motivation to rise. 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.
오 카 투 르If 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.
배치할 때는 다른 성분에 따라 따로 보관해야 하며 함께 혼합해서는 안 된다.구리 표면에는 전해질이 있을 수 있기 때문에 반응할 수 있으며， 특히 고무 등 다른 재료와 반응할 수 있어 큰 영향을 미칠 수 있다.
용접 공구의 드라이어는 열이 지나치게 집중되지 않도록 너무 작아서는 안 된다.
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.
축축한 공기 중의 구리의 부식은 일종의 화학 반응으로， some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well， and the price of raw materials has risen， so the iron price has risen. The iron mills have a high enthusiasm for producing steel， so there is not much cast iron resources， and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting， and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand， the pig iron market is performing well and is expected to continue to operate strongly in the short term.
시장 부The difference between hard copper tubes and soft copper tubes in use Hard copper tubes can only be used as straight tubes and cannot be bent. Therefore， they are generally used in power plants， switches of electrical equipment， and places where the connection points are far away and do not need to be bent. Compared with soft copper tubes， the price of hard copper tubes will be lower. Although the name of the soft copper tube is soft tube， it can also be used as a hard tube， so the soft copper tube is used in more places，포 탈 람201 스테인리스 강판， asell as in a coiled tube way. The length of the copper tube can be longer if the coil is used. If the connection point is longer it can be cut randomly according to the length，포 탈 람304 스테인리스강 원강， so as to prevent leakage when welding the copper tube. Soft copper pipes are used in many refrigerators，포 탈 람310s 스테인리스 강판， air conditioners and other places where bending pipes are needed. When we use copper， we need not consider the preservation problem unless we buy a small amount at home. For example， large manufacturers use copper units to buy a large number of copper pipes once， so there will be a problem. I believe some people do not know how to store unused copper materials， Now lets ask our staff to introduce the storage method of copper for you.
Because of the characteristics of copper itself， it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it， the problem will be smaller， but if it is placed for a long time， the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.
압출법: 본 생산 방법은 정련 후 구리 주괴를 주조하고 차 가열 후 대형 압출기로 구리 파이프를 압출한다.
적동판은 연전성을 가지고 있다.순수한 구리는 물 한 방울만큼 커서 킬로미터 길이의 가는 실로 끌려가거나 침대보다 더 큰 투명박으로 말릴 수 있다.자동 배열의 가장 가치 있는 특성은 매우 좋은 전도성을 가지고 있으며， 그 다음이다일반 금속 중에서.그러나 구리는 은보다 훨씬 싸기 때문에 이미 & amp;quot；주인공 & amp;quot；전기 업계의 리더.
목표.경동관과 연동관의 사용 중의 차이는 경동관은 직관으로만 사용할 수 있고 구부려서는 안 된다.따라서 일반적으로 발전소， 전기 설비의 스위치 및 연결점이 멀고 구부릴 필요가 없는 곳에 사용됩니다.경동관은 연동관에 비해 가격이 더 싸다.소프트 구리 파이프의 이름은 soft tube이지만 하드 파이프로도 사용할 수 있으므로 소프트 구리 파이프는 더 많은 곳에서 사용되며 직관 방식으로 사용할 수 있습니다. 예를 들어헬리컬 파이프 방식으로.코일을 사용하면 구리 파이프의 길이가 더 길어질 수 있습니다.첨부 점이 긴 경우 길이에 따라 임의로 절단하여 구리 파이프를 용접할 때 누출을 방지할 수 있습니다.소프트 구리 파이프는 많은 냉장고， 에어컨 및 튜브가 필요한 다른 곳에 사용됩니다.우리가 구리를 사용할 때， 우리는 집에서 소량을 구매하지 않는 한 보존 문제를 고려할 필요가 없다.예를 들어， 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.

포 탈 람To sum up the market in Northeast China is generally pessimistic based on the medium and long-term policies and the general environment， as well as the current inventory level in Shenyang. The low inventory level of copper platoon makes the whole market lack of motivation. The copper bar market in this city has stopped this year， and it is hard to improve in the short and medium term. On the whole， the market price of Shenyang copper bars may be stable tomorrow.
On October ， according to the Economic and Information Commission oong Province， at the end of September ， Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel， and all the de capacity equipment had been shut down and withdrawn. On October ， the Development and Reform Commission of Handan City released the Plan for Handan City to Eliminate Excess Iron and Steel Capacity. Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.
For small diameter pipes when using filler metal， the length of filler metal is allowed to be equal to the diameter of the pipe， which is enough to fill the weld crater. One of the five major application fields of red coppr plate T， red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries， motors and transformers， switches and printed circuit boards; In the manufacture of machinery and transport vehicles， it is used to manufacture industrial valves and accessories， instruments sliding bearings， molds， heat exchangers， pumps， etc.
