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，인도네시아304 스테인리스 강판， 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.
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 * *， 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.

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， 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， 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.
가라오케.Lets 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， heats the floor， 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 pipeo 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.
The hard copper tube is not artificially treated after being drawn or extruded， so that it can be naturally formed. At this time， the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore， the hard copper tube is generally straight.
In 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.
On the other hand， in the steel plant， the lock price of the steel plant has been falling all the time and the order receiving is poor. The capacity utilization rate of the steel plant is low， but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising， so the market price has fallen sharply. Subsequently， the futures market rebounded in a wave， with the decline of black futures， the market transaction volume shrank significantly. In addition， the inventory pressure was high， traders shipped at low prices， and the spot price fell under pressure. Due to the strong drop resistance of medium and thick plates， the drop amplitude and rate are less than those of threads.

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.

The application of copper tube The copper tube is generally used in the heat exchange equipment，인도네시아붉은 동관， and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids， and can also be used as pressure measuring tubes in instruments; In addition， the copper pipe is relatively firm unlike other metals， which are easily corroded， so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.

잠재력 발전Disadvantages: 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.
Reasons for copper pipe corrosion: Air pollution.

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， 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.
