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， 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.
칸 트 하 라 크How to preserve the copper tube? In order to protect the excellent performance of copper pipes from the impact of the environment， we need to do the following: First， select appropriate sites and warehouses， cement， etc.
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， 강소， 하북과 산서의 주철공장은 아주 적고 재고는 여전히 매우 낮다.코크스 가격이 오르고 원가가 증가함에 따라 주철공장의 가격이 다시 올랐다.
Ecateepec 회사In view of the current overall price difference， the local copper bar price continued to rise at a high level today， while the regions outside East China did not show an obvious follow-up trend， and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction， and the price support of copper bar is still strong. However， at present， domestic real estate control is still being tightened. The markets expectation of future demand is weakening and the markets fear of heights appears after the price rises.Today， the market price of copper bars in Shenyang is stable and the shipment is poor.
또 다른 집산지인 강음시장에서 현재 유통단계의 전체 재고는 약 만 톤으로 정상 수준보다 약간 낮다.이번 주 초 강음 가격과 북방 가격 간의 가격 격차도 약간 낮은 유통 재고에 대응했다.그러나 제철소 정책항을 보면， 남강， 항윤， 다다 등 전체 생산 상황은 비교적 정상이며， 후기 자원량은 안정을 유지한다.락종시장의 전반 재고는 만~만톤 좌우를 유지하여 중등정상수준에 속하며 최근 락종시장의 현물가격은 북방과 비교적 큰 차이가 있다.
쌓을 때는 합리적으로 쌓고 우선적으로 놓아야 한다.
antages: low production cost and high production efficiency.
In addition， it is very strong， 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 many times in other places.The color change on the outer surface of the copper tube is difficult to control due to environmental factors. To prevent moisture absorption on the surface and core of the annealed brass tube， a constant temperature and humidity packaging room can be built. Packaging in the packaging room can avoid the color change on the outer surface of the copper tube. However， it is not easy to control the situation that occurs in the processing process. The cost of ensuring constant temperature and humidity in the whole workshop is too high. The following measures are taken to control the process materials: In the season of high temperature and humidity， during the production and processing of copper tubes， the amount of oil coating on the surface of copper tubes can be increased to form an oil film on the surface of copper tubes， which can isolate water vapor and corrosive gases， and prevent the corrosion of the surface of copper tubes; The humidity in the air at night is high， and the outer surface of the copper pipe is prone to corrosion and discoloration at night. Closing the doors and windows of the workshop at night can make the situation worse; After the coil surface is cleaned in the rewinding process， the coating amount of passivation agent on the copper tube surface is increased. After blanking in the rewinding process， plastic bags shall be added to the whole support material to further reduce the contact between the copper pipe and the air and prevent the surface of the copper pipe.
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.
관리 하 다.In terms of steel billets: at :， some steel billets in Changli were reduced by ， and the current carbon square billets were delivered with tax of yuan. After the th National Congress of the Communist of China， the market had doubts about the uncertainty of environmental production restriction and was still waiting for a clearer direction. Therefore， it can be seen that at this stage， there was no unilateral market for either futures or cash， and there was no definite pattern of ups and downs.According to the monitoring data of Lange Iron and Steels cloud business platform， as of the time of publication Tianjin Youwelded Line: the steel mill reported: Rongcheng # yuan/ton， B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton， and that of B steel is yuan/ton; Jiyuan # yuan/ton， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton， B steel yuan/ton.

단점: 파이프 구조가 느슨하고 고압에 약하다.그것은 소형 에어컨 동관 생산에만 적용된다.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
칸 트 하 라 크Because 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.
Save materials and total cost， stability and performance， and can save maintenance.
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.
