남편.Finished products must be stored indoors. During storage， they should be protected from direct sunlight to the copper tubes. During the transfer， transportation and loading and unloading of copper tubes， rain should be avoided; In summer， the ambient temperature of copper pipe is high and the speed of copper pipe surface is accelerated. When storing copper pipe， pay attention to the principle of first in first out to reduce no loss; The copper pipe loading process is better carried out indoors to avoid the copper pipe being exposed to the sun， so as to accelerate the speed of the outer wall of the copper pipe. After the loading is completed， at least two layers of canvas shall be used to tightly wrap the whole vehicle materials; After loading， if the truck can not depart in time， the truck shall be driven to the back of the sun to prevent the goods from being exposed to the sun for a long time to absorb heat.
Advantages of red copper tube Durability: copper has stable chemical properties integrating cold resistance， heat resistance， pressure resistance， corrosion resistance and fire resistance， and can be used in different environments for a long time.
라 그 도If you want to make the copper surface become bright again， but also quickly remove the rust and oxide layer on the copper surface to restore the luster of the copper itself.
The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm， the elongation is ~%， and the Brinell hardness (HB) is ~
Disadvantages: Due to loose tissue and high pressure resistance， the pipe is only used to produce small air conditioning copper rods.
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.

Later， Mexican scientists also found that copper has a . Recently， British researchers found that copper has a strong bactericidal effect. It is believed that in the near future， copper will make great contributions to improving human health. Copper plate T is named after its purple color. It is not necessarily pure copper， sometimes it also involves a few deoxidizing elements or other elements to improve raw materials and s，남편.6063 알루미늄 바， T， T， oxygen free copper plate (TU， vacuum oxygen free copper)， deoxidized copper plate (TUP， TUMn)， and special copper plate (arsenic copper， tellurium copper， silver copper) with a few alloy elements added. The conductivity and thermal conductivity of copper plate are second only to silver， and are widely used to manufacture conductive and thermal conductive devices. The red copper belt has outstanding corrosion resistance in the atmosphere sea water， alkalis some non oxidizing acids， salt solutions and a variety of organic acids (aic acid， citric acid)， and is used in the chemical industry. In addition， the red copper plate has outstanding weldability and can be made into various semi products and products through cold and thermoplastic processing. In the s， the output value of copper plate exceeded that of other copper alloys.
Do not store too many other products， especially other acid materials and alkali materials， in the warehouse to prevent mutual reaction.
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.

남편.파이프를 카드 상단에 삽입하고， due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants， the gradual emergence of supply and demand pressure， and the weakness of raw material support， among which the contraction of market demand has a greater impact. Therefore， the author believes that in the short term， the spot building materials do not have the possibility to rise significantly， and the price of building materials may mainly operate in shock， but with the shrinking demand， the supply and demand pressure becomes prominent， However， considering the influence of winter storage and other factors， it is still possible for merchants to lower the spot price in November.
