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，쿠 알라 룸 푸 르12Cr1MoV 합금 강판， 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.

Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand， the continuous decline of iron ore port inventory may end. In addition， according to the new statistics of * *， the available days of imported iron ore of steel mills are days， which is one day lower than that before the National Day， and is on the high side of history. The steel mill said that at present， the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction， the steel mill is not willing to replenish the inventory.

Overview of three production methods of copper tube Copper tube is a very important material for copper materials. There are many ways to complete the production of this copper tube. For copper pipes， the following three methods are generally used to produce materials. The copper tubes produced by these three methods are not only very good in performance， but also very convenient to operate. There are three production methods for copper tube， so what are the three production methods for copper tube?

As of August ， 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， and some traders shipped at low prices. The market inventory rose， the inventory pressure was high， and the market transaction atmosphere was cold， the demand performance continued to decline， and the spot price fell under pressure. At present， the fundamentals faced by the domestic copper bar market are still mixed. On the one hand， the market supply is expected to shrink， but on the other hand， the northern market has entered the off-season of demand and the markets expectation of future demand is pessimistic. In the short term， domestic steel prices will enter the operating track of range consolidation. To sum up， considering the current situation of demand and inventory in the steel market， it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching， environmental protection phenomena such as steel mills are still going on， and black series speculation is still taking place. But personally， the fluuation range of the market in this region is limited， and businesses can operate flexibly on a short-term basis， and the shipment transaction is * * *. 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，쿠 알라 룸 푸 르310s 스테인리스강 원강， 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
