It is mainly used to manufacture electrical devices such as generators, buses, cables, switchgear, transformers, and thermal conductive devices such as flat plate collectors for heat exchangers, pipes, and solar heating equipment. Common copper alloys are divided into three categories: brass, bronze and white copper. Pure copper plate is a purplish red metal, commonly known as & quot; copper plate& quot;, & amp; quot; red copper plate& quot; or & quot; red copper plate& quot;.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.Sabal,When the purity of pure copper is higher, the corrosion resistance is better. Copper pipes processed with recycled copper are easy to cause corrosion due to impurities inside. (I) Problems that should be noted in copper pipe welding are generally %. % % or % silver electrode shall have good fluidity and be assisted by flux. The flux used shall be a flexible mixture or powder,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,Sabal12cr1mov alloy round steel, so it has become the & quot; protagonist& quot; of the electrical industry.Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.The production method of soft copper tube is basically the same as that of hard copper tube, that is, the annealing process is added compared with the hard copper tube. Annealing of copper tubes means that they are calcined in a high temperature furnace to change the arrangement of the elements in the copper tubes. However, after annealing, the copper tubes will become soft, which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.

In addition, it is 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 for many times in other places.The more residual chloride ions, the deeper the corrosion pit of water.When stacking, it shall be stacked reasonably and placed first.Recommendation and consultation,Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.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.Save materials and total cost stability and performance, and can save maintenance.

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, 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, 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.technological innovation,If the corrosion on the copper surface is found to be slight, it can be erased with linen copper wire, but it is not recommended to apply oil for preservation.Copper pipes of different models shall be stacked separately.The blowpipe shall be perpendicular to the lead pipe during welding, and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.SabalThe hard copper tube is not artificially treated after being drawn or extruded, so that it can be naturally formed. At this time,SabalTinned copper bar, 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.The simplest way is to use copper cleaner. Brass, red copper, bronze, etc. can be used. Oil stains,SabalQ345D alloy round steel, fingerprints, oxide layers, etc. on the surface can be cleaned with copper cleaner first.Today the price of tube billets is up and down. At present, Jiangxin hot rolling is yuan, continuous casting yuan is down yuan, Dongfang hot rolling yuan is down yuan, Luli hot rolling yuan is down yuan, production is stopped in mid January, continuous casting yuan is up yuan, Huaigang yuan is up yuan, Zhongtian yuan, Changqiang yuan
