However， it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits， Tangshan Iron and Steel Group Co.， Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits， or to lay hidden dangers for the decline. As far as tomorrow is concerned， the price may still maintain a narrow range of shock operation pattern.
日中後期には，先物価格の上昇や武鋼の生産制限政策の増加などの朗報があったにもかかわらず，ある地域では，在庫レベルが高いため，貿易商は値上げの意思がなく，彼らの多くはすでに出荷されており，現物価格は上昇の動力に欠けている.市場在庫が大幅に増加した.当時，邯鄲の市場在庫は節後に高い水準に達した.長期的な低迷した需要表現は市場の供給過剰を招き，在庫の上昇が続いて市場の心理状態が空虚になった.
ジットラ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，ジットラ5052アルミニウムストリップ， 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.
Red copper plate has ductility. Pure copper， which is as big as a drop of water， can be pulled up to two kilometers of thin wire or rolled into a transparent foil larger than a bed. The most valuable property of red copper row is that it has a very good conductive ， second onlyver in common metals. But copper is much cheaper than silver， so it has become the "protagonist" of the electrical industry.

When welding， just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.

According to * * new data， in September ， Chinas imported iron ore * * * broke through the million ton mark， reaching million tons， a record high; From January to September， Chinas iron ore import increased by % to million tons， and the annual import volume is expected to exceed billion tons. However， due to the rapid declinecline in iron ore prices， the iron ore price index once fell below $， which reduced the enthusiasm for the shipment of imported ores. In addition， environmental protection inspection has become stricter， and the supply of some domestic mines has been greatly affected. The current operating rate of domestic mines is percentage points lower than the previous peak， which is likely to decline further in the future.
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， so that copper tubes can be produced with the separated copper ions. This method is very complex and copper ions can be separated by conductivity， requires high technology and new equipment， so only advanced foreign countries can use this production method.
どこにありますか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.

The 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， 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.
ジットラTo sum up， 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，ジットラステンレス溶接管， 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.

It is said that due to the optimistic future and tight resources， some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well， and the price of raw materials has risen，ジットラ316 Lステンレスパイプ， so the iron price has risen. The iron mills have a high enthusiasm for producing steel， so there is not much cast iron resources， and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting， and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand， the pig iron market is performing well and is expected to continue to operate strongly in the short term.
