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.The copper tube shall be heated and welded first, and then the joint shall be heated until the heated part turns dark red. At this time, when the filler metal contacts the tube, the filler metal shall melt.Weige,Copper pipe corrosion caused by soft water.Save materials and total cost, stability and performance, and can save maintenance.Dar es Salaam,Weige310s stainless steel welded pipe,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, and sintering machines using semi dry desulphurization continued to be shut down for %. The access of vehicles is alicted. The port collection and distribution vehicles are prohibited from entering and leaving the port area. The city s steel continue to implement the measures of stopping and limiting production specified in TZBZ [] No. document. All sintering machines and shaft furnaces using wet desulphurization in iron and steel enterprises in the city were shut down, coking, electric power, cement, chemical and other key vehicle enterprises are not allowed to transport vehicles into and out of the plant. After : on October , and the purchase of iron ore may still maintain a small amount of prudence. In addition, due to the influence of industrial users & amp; quot; coal to gas& quot;, the recent performance of coke is weak. Therefore, in terms of steel plant production, the support of raw materials is weak.The market opened today. Although the performance of Zitong Pai futures was modest, the overall market has stopped. The market mentality has not changed much sincekend. The price is stable, but some specifications are subject to negotiation, and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold. In the middle of winter, the overall market in Northeast China has entered the traditional off-season, and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature, the market was bleak.

Copper tube is also called copper tube nonferrous metal tube. It is a pressed and drawn seamless pipe characterized by light weight, good thermal conductivity, high low-temperature strength and corrosion resistance. Because of these excellent properties of copper tubes, 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.Affordable price,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 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 of red copper tube Durability: copper has stable chemical properties, integrating cold resistance, heat resistance, pressure resistance, and can be used in different environments for a long time.

The copper tube shall be heated and welded first, and then the joint shall be heated until the heated part turns dark red. At this time, the filler metal shall melt.Quality assurance,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, 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.Reasons for copper pipe corrosion: Air pollution.The simplest way is to use copper cleaner. Brass, red copper, bronze, etc. can be used. Oil stains, fingerprints, oxide layers,Weige310s stainless steel coil, etc. on the surface can be cleaned with copper cleaner first.Weige,Advantages and scope of application of copper tube ground heating At present, ground heating is not only a comfortable heating method, but also a symbol of modern life quality. More and more houses, public buildings, 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.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 Tiangang hot rolling an is down yuan, production is stopped in mid January, Weigang hot rolling yuan is up yuan, continuous casting yuan is up yuan, Huaigang yuan is up yuan, Zhongtian yuan, Changqiang yuan, Linggang yuan.When welding, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.
