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.
The conductive production of copper tube is the latest method for this method. It is the production of nanocrystalline copper materials with conductivity. Because this raw material is very special， it is a copper material produced by using nanotechnology， and copper ions can be separated by conductivity， so that copper tubes can be produced with the separated copper ions. This method is very complex， so only advanced foreign countries can use this production method.

Although 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， the overall demand for strip steel remains in a good state.
In the morning trading today， the price of domestic copper bar fell. According to the monitoring data of Lange Steels cloud business platform， the average price of * mm hot rolled strip in key cities in China is ， down yuan from yesterday. Futures prices fluctuated， the market was mainlysee yesterday， which caused the overall transaction blocked， and the mainstream manufacturers prices fell today.
In Jiangyin market， another distribution center， 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， the overall production situation of Nangang， 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.

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， and places where the connection points are far away and do not need to be bent. Compared with soft copper tubes，모 빈7075 알루미늄 튜브， the price of hard copper tubes will be lower. Although the name of the soft copper tube is soft tube，모 빈동대， 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.

얼마Lets elaborate on the advantages of copper pipe materials: copper pipe floor heating refers to a heating method that uses hot water as the thermal medium， circulates in the copper pipe heating pipe， and heats the floor through the ground in the form of radiation and convection heat transfer. I. The copper tube has fast heat dissipation effect and strong heat resistance. Even under the condition of high temperature water supply the service life of the floor heating tube will not be affected. Two. Copper pipe is a metal pipe，o it is not easy to scratch. Therefore， it is not easy to leak. Three. High temperature resistance， high pressure resistance， relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.
Under the action of high welding temperature， the evaporation amount of zinc is as high as % during shielded metal arc welding. A large amount of zinc evaporation leads to the decline of mechanical properties and corrosion resistance of welded joints， especially other acid materials and alkali materials， in the warehouse to prevent mutual reaction.
