If you want to avoid this kind of situation for a long time, 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.The excellent performance of copper pipe The copper pipe has the characteristics of and which makes it a suitable choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial housing.Tissau yveros,Regularly inspect and monitor the copper pipe to reduce the loss caused by copper pipe corrosion.In Jiangyin market,Tissau yverosT2 copper plate, 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, 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.Chachak,Because of the characteristics of copper itself, the problem will be smaller, the copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.Save materials and total cost, stability and performance, and can save maintenance.Save materials and total cost stability and performance, you can choose passivation treatment. In this way and can save maintenance.

If you want to avoid this kind of situation for a long time, not only is the copper surface serious, it can be cleaned under normal circumstances, so this effect is very good.When stacking, reasonable stacking and first in first out shall be achieved.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.Safety production,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 * *,Tissau yveros40Mn2 alloy steel plate, the available days of imported iron ore of steel mills are days, 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.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.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.

The price of pig iron market rose by - yuan this week, and the transaction was fair. With the increase of coke price, the cost of ductile iron in Shanxi, Liaoning, Shandong and other regions has increased. In addition, with the gradual release of downstream demand, the inventory of iron plants is not large, and iron plants have successively raised their prices. There are few iron foundries in Shandong, Jiangsu, Hebei and Shanxi, and the inventory remains low. As the coke price rises and the cost increases, the price of iron foundries rises again.Product line,Insert the pipe into the top of the bayonet,e the sleeve on the pipe to evenly apply the flux on the joint, and confirm that the pipe is inserted into the bottom of the socket, then wipe off the excess flux, and the joint is assembled and can be heated.Finished products must be stored indoors. During storage, they should be protected from direct sunlight to the copper tubes. During the transfer, transportation and loading and unloading of copper tubes, rain should be avoided; In summer the ambient temperature of copper pipe is high, and the speed of copper pipe surface is accelerated. When storing copper pipe, pay attention to the principle of first in first out to reduce no loss; The copper pipe loading process is better carried out indoors to avoid the copper pipe being exposed to the sun, so as to accelerate the speed of the outer wall of the copper pipe. After the loading is completed, at least two layers of canvas shall be used to tightly wrap the whole vehicle materials; After loading, if the truck can not depart in time, the truck shall be driven to the back of the sun to prevent the goods from being exposed to the sun for a long time to absorb heat.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.Tissau yveros,The second of the five application fields of red copper plate T, red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels, distillation pots, brewing pots, etc.The simplest way is to use copper cleaner. Brass, red copper, bronze, etc. can be used. Oil stains, fingerprints, oxide layers etc. on the surface can be cleaned with copper cleaner first.Some steel mills in Liaoning are interested in purchasing pig iron, but the local resources are tight, and the iron mills quotations are on the high side, 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.
