Disadvantages: 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.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.Soweto,As the copper pipe is easy to process and connect, it can save materials and total cost, stability and reliability, and can save maintenance during installation.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.Wakayama,The difference between hard copper tubes and soft copper tubes in use Hard copper tubes can only be used as straight tubes and cannot be bent. Therefore they are generally used in power plants, switches of electrical equipment, and places where the connection points are far away and do not need to be bent. Compared with soft copper tubes, the price of hard copper tubes will be lower. Although the name of the soft copper tube is soft tube, it can also be used as a hard tube, so the soft copper tube is used in more places and can be used in a straight tube way, asell as in a coiled tube way. The length of the copper tube can be longer if the coil is used. If the connection point is longer, it can be cut randomly according to the length, so as to prevent leakage when welding the copper tube. Soft copper pipes are used in many refrigerators, air conditioners and other places where bending pipes are needed. When we use copper, we need not consider the preservation problem unless we buy a small amount at home. For example, large manufacturers use copper units to buy a large number of copper pipes once, so there will be a problem. I believe some people do not know how to store unused copper materials, Now let s ask our staff to introduce the storage method of copper for you.Advantages and scope of application of copper tube ground heating At present, but also a symbol of modern life quality. More and more houses, public buildings, sports facilities, industrial facilities and other places begin to use ground heating radiator, which is an important part of ground heating. Due to the corrosion resistance of copper, copper tubes are selected as the main material of radiator in many places.Tangshan billets rose sharply last weekend, steel mills in some northern cities implemented production restriction, and some domestic economic data improved, steel prices generally rose. However, with the approaching meeting and the rainfall in the south caused by the typhoon, the construction progress of the downstream construction site is affected, which is not conducive to the continuous demand. The high spot price transaction today is weak, which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow, and some businesses may reduce prices and take goods.

The simplest way is to use copper cleaner. Brass, bronze etc. can be used. Oil stains, fingerprints, oxide layers, etc. on the surface can be cleaned with copper cleaner first.(Brass is a copper zinc alloy. Due to the low boiling point of zinc, which is only ℃, it is very easy to evaporate during welding, which becomes a problem in brass welding.If you want to avoid this kind of situation for a long time,Soweto304L stainless steel plate, you can choose passivation treatment. In this way, not only is the copper surface serious, it can be cleaned under normal circumstances, but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment, so this effect is very good.Market trend, but the total pressure is not big. From the current overall inventory situation of the main distribution centers Wu an Jiangyin and Lecong, the inventory level remains relatively moderate and the pressure on the market is relatively small. In Wu an market, as of May ,SowetoAluminum bronze plate, the total inventory of medium and thick plates in Wu an was close to tons, increasing by tons on a weekly basis. In late April, it reached tons lower in the year, down tons from the high level after the Spring Festival, and rose for three consecutive weeks. In terms of the ovquantity, it should be said to maintain a relatively moderate level.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.Later, Mexican scientists also found that copper has a . Recently, 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, citric acid), and is used in the chemical industry. In addition, 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, the output value of copper plate exceeded that of other copper alloys.

Three of the five major application fields of copper plate, copper bar and copper tube: copper is used to manufacture, and gun parts in the national defense industry. Every million rounds of copper are produced, - tons of copper are needed.Installation conditions,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, and copper ions can be separated by conductivity, so that copper tubes can be produced with the separated copper ions. This method is very complex, requires high technology and new equipment, so only advanced foreign countries can use this production method.Four in one formula and process conditions Preparation of solution Take formula as an example: mix the calculated amount of water for zinc oxide into a paste, slowly add it into the calculated amount of phosphoric acid under stirring until it is completely dissolved, then add zinc nitrate and tartaric acid, dilute it with water to / of the total volume, add sodium alkosulfonate and OP emulsion, and stir to make it completely dissolved. Then add chromium dihydrogen phosphate dissolved in dilute phosphoric acid, and add titanium sulfate. After all materials are added, stir them to make the solution even, put a large amount of iron filings in the solution, and soak them for - days to make them contain enough ferrous ions. When the content of ferrous ion reaches above g/L, adjust the free acidity and total acidity of the solution to the specified value, and then the solution can be used at elevated temperature. When the ferrous ion reaches the above value, the phosphating speed is fast, the solution is stable, and the phosphating film is fine and dense. During operation, not on the bottom of the tank the degreasing technology of degreased copper pipe. How to make degreased copper pipe? The process flow of degreased copper tube? What are the characteristics of degreased copper tubes? Use of degreased copper tube? There are too many questions. Let s solve them at once. Everyone knows the copper tube. Nitrate reacts easily. The heater should be installed on the two walls of the tank, to prevent local overheating. Stainless steel pipe or iron pipe should be used for heater, and lead pipe or copper pipe should not be used to avoid contamination of solution by impurities. What is degreased copper pipipe? & amp; quot; The advantages of degreased copper pipe s comprehensive treatment of grease, rust removal, phosphating and passivation are described. This comprehensive treatment process can simplify the process, reduce the work area, save equipment costs, shorten working hours, improve labor productivity and reduce costs. This method can only be used in the occasions where the requirements for coating quality are not high. However, in actual production, due to the amount of oil contamination, light and heavy rust, the consumption rate of each component in the solution is different, so attention should be paid to adjustment and control to maintain its due role. What is the degreasing copper tube? & amp; quot; I have roughly known the degreasing methods of degreasing copper tubes: solvent degreasing,Soweto12Cr1MoV alloy steel plate, alkali degreasing, ultrasonic degreasing, high pressure hot water degreasing, electrolytic degreasing etc. Solvent degreasing: use degreasing solvent to dissolve the oil on the surface of red copper pipe, collect it together into a container, volatilize, collect and reuse the volatile solvent, and separate the pollutants from the circulation system. This method was used in the early stage, which has problems such as low cleaning efficiency, difficult maintenance, and environmental pollution. In recent years, many kinds of surfactants have been developed. The lipophilic group of surfactants can help to dissolve oil in water to realize degreasing. Alkali degreasing: Alkali degreasing is a complex chemical physical process. In addition to saponification reaction, there are sometimes emulsion reaction and adsorption reaction. Typical saponification reaction formula is as follows: RCOOH+NaOHRCOONa+HO At present, industrial degreasers are composite reagents, and the solution temperature is ℃. Ultrasonic degreasing: ultrasonic degreasing is to degrease the upper and lower surfaces of red copper pipes by using ultrasonic to generate high-speed vibration, whichtly used for monomer and irregular shaped components. High pressure hot water degreasing: without degreasing agent, heat the deionized water to ℃, and spray it directly to the surface of red copper pipe for cleaning under the pressure of about bar. Electrolytic degreasing: electrolytic degreasing, using the red copper tube as the cathode to generate H, which will scour the oil stain on the surface of the red copper tube; The O generated by the anode is in atomic state and has strong oxidation capacity, which can improve the degreasing effect. Therefore, the problem that alkali spraying and brushing cannot fully contact the micro concave part of the surface is solved. Generally, the cleaning effect of alkali degreaser spraying or high-pressure hot water degreasing plus brushing can meet the requirements of most users. If there are special requirements, multiple methods can be used together. According to practical experience, the degreasing effect of various degreasing methods (one side of the copper tube) is as follows: alkali degreaser spray plus brushing: mg/m alkali degreaser brushing plus electrolytic degreasing: mg/m ultrasonic wave: mg/m high-pressure hot water degreasing:& lt; mg/m degreasing copper tube What is the degreasing purpose of the degreasing copper tube? The purpose of degreasing is to provide a clean surface for the copper pipe and lay a foundation for the subsequent process of coating. What is degreased copper tube? & amp; quot; We learned about the cleaning degree detection method of degreased copper tube: Visual inspection. Wet the degreased workpiece surface with water, and determine the cleanliness according to the complete adhesion of the surface water film. This is the most commonly used method to detect the degreasing quality. Wipe method. Wipe the degreased and dried workpiece surface with clean white silk cloth or filter paper. If there is no oil stain on the surface of filter paper or silk cloth the degreasing effect is good. Copper sulfate method. This method is divided into copper sulfate immersion method and copper sulfate dropping method. The copper sulfate immersion method is to immerse the degreased workpiece in the acidic copper sulfate aqueous solution, and wash it with water. Degreasing red copper pipe shall be evaluated for cleanliness according to the copper film. The copper film is complete and uniform, with good luster and adhesion, indicating that there is no oil stain on the surface of the workpiece. This method is suitable for small workpieces.For small diameter pipes, when using filler metal, the length of filler metal is allowed to be equal to the diameter of the pipe, which is enough to fill the weld crater. One of the five major application fields of red coppr plate T, red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries, accounting for more than half of the total consumption. Used for various cables and wires, motors and transformers, switches and printed circuit boards; In the manufacture of machinery and transport vehicles, it is used to manufacture industrial valves and accessories, instruments, sliding bearings, molds, heat exchangers, pumps, etc.Soweto,First of all, we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C, while the humidity should be normal. The room should be kept ventilated.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.
