Among the three production methods of copper tube， the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material， the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time， but also has a mature technology， which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.
In Jiangyin market， 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.

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 and the downstream mainly focuses on callback buying without panic inventory clearing. It can be seen that although the steel market continues to shake， the overall demand for strip steel remains in a good state.
The copper tube welding process is to radiate the copper tube bundle with excellent directivity， high brightness， high strength， high coherence and other characteristics to the surface area of the workpiece to be processed. After the copper tube bundle is focused by the optical system， through the interaction between the copper tube and the object to be welded， a highly concentrated heat source area can be formed at the place to be welded in a very short time. The heat energy makes theea to be welded melt， cool and crystallize to form a solid welding spot and weld seam.
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 and the spot price also increased with the increase. There was an instant of large volume of transactions. However， 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.

Due to low pig iron inventory， some steel mills in Jiangxi have resumed purchasing recently， but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently， the steel market has been in shock and adjustment， and the merchants are unstable. Steel mills in Hebei， Tianjin and other regions have stopped producing pig iron for steelmaking. Now， it is mainly expected to make inquiries. However， due to the lower price of raw materials， the price of iron mills has been lowered.

Copper is light.
The material of the water separator is the same， the expansion coefficient is the same， and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe， the cost of the floor heating system is higher.

Some steel mills in Liaoning are interested in purchasing pig iron，무성 한 물건304 스테인리스 강판， but the local resources are tight， and the iron mills quotations are on the high side， resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu， Shandong， Shanxi， Hebei， Henan and other regions is sluggish， and the inventory pressure of iron mills is increasing. As the price of raw materials decreases， the quotation of iron mills continues to decline. At present， the demand and cost support are weak， and there is no positive boost. The short-term pig iron market is weak and difficult to change.antages: 낮은 생산 비용과 높은 생산성.
