The supplier is required to provide technical performance indicators such as viscosity， acid value and distillation range， and the third-party test report of elements harmful to copper tubes. In the rewinding process， strengthen the cleaning of the copper tube surface to reduce the residue of lubricating oil on the copper tube surface.
Generally， oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.
지 노 이 모Later， 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， so it is also included in copper alloys. The processed materials of Chinese cor plate can be divided into four categories according to the composition: ordinary copper plate (T， T， T， T， oxygen free copper plate (TU， TU and high-purity， 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， some non oxidizing acids， alkalis salt solutions and a variety of organic acids (aic acid， 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 and is used in the chemical industry. In addition， the output value of copper plate exceeded that of other copper alloys.
At present， the fundamentals faced by the domestic copper bar market are still mixed. On the one hand， the market supply is expected to shrink， but on the other hand， the northern market has entered the off-season of demand， and the markets expectation of future demand is pessimistic. In the short term， domestic steel prices will enter the operating track of range consolidation. To sum up， considering the current situation of demand and inventory in the steel market， it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching， environmental protection phenomena such as steel mills are still going on， and black series speculation is still taking place. But personally， the fluuation range of the market in this region is limited， and businesses can operate flexibly on a short-term basis， and the shipment transaction is * * *.

Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.

In consideration of the above factors， and the production limit in Wuan and Tangshan heating seasons has been advanced. In addition the formal implementation of production limit in "+" urban heating seasons after November by steel enterprises， the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high， and the willingness to further replenish the inventory is not strong. In terms of supply， the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection， the short-term iron ore market may lack upward momentum.

On October ， the Development and Reform Commission of Handan City released the Plan for Handan City to Eliminate Excess Iron and Steel Capacity. Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.
When placing， they should be stored separately according to the different components， and should not be mixed together. The copper surface may have electrolytes， so it will react， especially with other materials such as rubber， which has a large impact.

Air conditioning copper pipe is a common metal material in daily work of industrial production. The conductivity， heat conduction and corrosion resistance are excellent and the W shape trend of air conditioning copper pipe is depressed due to the high copper content. Good machinability， fusion welding and brazing are very good. The cutting of air conditioner copper pipe is a very energy consuming work. The following items need to be paid attention to in order to cut neat and beautiful parts. Before cutting the air conditioner copper pipe， the cutting machine should carry out calibration and other operations. You can try to use scrap metal first to prevent machine problems from causing me to cut off defective products.
In the first ten days of May， the overall order receiving quantity of Tianjin Hebei Henan Plate Plant was not ideal. According to the monitoring data， the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak. Due to the weak market shock， the overall order intake of the spot steel market was relatively weak. The total quantity of orders received in the first ten days of May is only about tons， while at the end of April， the total quantity of post settlement agreements of main steel plants can exceed tons.

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，온두라스동대， 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.
