동관 지온의 장점과 적용 범위는 현재 지온은 편안한 난방 방식일 뿐만 아니라 현대 생활의 질의 상징이기도 하다.갈수록 많은 주택，관직 을 주다.20CrNiMo 합금 강판， 공공건축， 체육시설， 공업시설 등 장소에서 지온라디에이터를 사용하기 시작하는데 이는 지온의 중요한 구성부분이다.구리의 내식성 때문에 많은 곳에서 구리 파이프를 라디에이터의 주요 재료로 선택한다.
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.
관직 을 주다.As the copper pipe is easy to process and connect， it can save materials and total cost， stability and reliability， and can save maintenance during installation.
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.
키 아 로 항First 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.
이번 주 양철 시장 가격은 - 위안 상승했으며 거래는 공정합니다.코크스 가격이 상승함에 따라 산시， 허난， 랴오닝， 산둥 등 지역의 잉크 주철 원가가 다소 증가하였다.이밖에 하류의 수요가 점차 방출됨에 따라 강철공장의 재고량이 크지 않아 강철공장이 륙속 가격을 인상했다.산동， 하북과 산서의 주철공장은 아주 적고 재고는 여전히 매우 낮다.코크스 가격이 오르고 원가가 증가함에 따라 주철공장의 가격이 다시 올랐다.
Because of the characteristics of copper itself， 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.
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， 대형 제조업체는 구리 유닛을 사용하여 대량의 구리 파이프를 한 번에 구매하기 때문에 문제가 발생할 수 있습니다.나는 어떤 사람들이 사용하지 않은 구리 재료를 저장하는 방법을 모른다고 믿는다. 지금 우리가 하자;우리는 우리의 직원에게 당신에게 구리의 저장 방법을 소개해 달라고 청했습니다.
연화수로 인한 동관 부식.
Among the three production methods of copper tube， the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material， the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time but also has a mature technology， which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.
자재 표를 설치 하 다The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently， the terminal demand has also shrunk due to the sudden drop in temperature， causing a weak shock. According to the communication with local traders in Cangzhou，관직 을 주다.6061 알루미늄 바， various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks， which is better in the off-season， and the shipment of some specifications has improved. However， the trading atmosphere in the small and medium-sized pipe market is still cold， and the demand is slowing down gradually. To sum up， it is expected that the market price of Cangzhou seamless pipe will be stable and weak in the near future.
연동관의 생산 방법은 경동관과 기본적으로 같다. 즉 경동관에 비해 퇴화 공정을 증가시켰다.동관의 퇴화는 그들이 고온로에서 하소하여 동관의 원소의 배열을 바꾼다는 것을 의미한다.그러나 불이 꺼지면 구리 파이프가 부드러워져 더 쉽게 구부러집니다.이런 방식으로 생산된 동관을 소프트 동관이라고 한다.
쌓을 때는 합리적으로 쌓고 우선적으로 놓아야 한다.
If you want to avoid this kind of situation for a long time， you can choose passivation treatment. In this way， 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.
순시 순찰 하 다.The hard copper tube is not artificially treated after being drawn or extruded， so that it can be naturally formed. At this time， the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore， the hard copper tube is generally straight.
To prevent the copper pipe surface， the humidity of the packaging materials should be well controlled， and the moisture content of all wood and paper packaging materials should be strictly controlled below %. Each plate of material is tightly packed with PE film to avoid the copper pipe absorbing moisture from the outside.
In Jiangyin market， the overall inventory of the current circulation link is about tons， slightly lower than the normal level. At the beginning of this week， the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However， from the perspective of the policy port of the steel plant， Hengrun， Dada， etc. is relatively normal， and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons， which is a medium normal level and the recent spot price of Lecong market has a large gap with that of the north.
관직 을 주다.On the other hand， in the steel plant，관직 을 주다.15CrMo 합금 강판， the lock price of the steel plant has been falling all the time， and the order receiving is poor. The capacity utilization rate of the steel plant is low， but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising， so the market price has fallen sharply. Subsequently， the futures market rebounded in a wave， and the spot price also increased with the increase. There was an instant of large volume of transactions. However， with the decline of black futures， the market transaction volume shrank significantly. In addition， the inventory pressure was high， traders shipped at low prices and the spot price fell under pressure. Due to the strong drop resistance of medium and thick plates， the drop amplitude and rate are less than those of threads.
The 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， and can be used in a straight tube way， 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， so as to prevent leakage when welding the copper tube. Soft copper pipes are used in many refrigerators， 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.
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.
