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.In Jiangyin market, 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.Lillestrom,Continuous casting and rolling method: This production method is to directly cast hollow copper billets after electrolytic copper smelting, and use planetary rolling method to produce copper tubes.The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently, the terminal demand has also shrunk due to the sudden drop in temperature, causing a weak shock. According to the communication with local traders in Cangzhou, various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks, which is better in the off-season, and the shipment of some specifications has improved. However, the trading atmosphere in the small and medium-sized pipe market is still cold, and the demand is slowing down gradually. To sum up, it is expected that the market price of Cangzhou seamless pipe will be stable and weak in the near future.Caravoso,In view of the current overall price difference, the local copper bar price continued to rise at a high level today, while the regions outside East China did not show an obvious follow-up trend, and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction, and the price support of copper bar is still strong. However, at present, domestic real estate control is still being tightened. The market s expectation of future demand is weakening, and the market s fear of heights appears after the price rises. Today, the market price of copper bars in Shenyang is stable and the shipment is poor.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 , so it has become the & quot; protagonist& quot; of the electrical industry.In the morning trading today, the price of domestic copper bar fell. According to the monitoring data of Lange Steel s cloud business platform, down yuan from yesterday. Futures prices fluctuated, and the prices of spot market manufacturers eased slightly today. According to the feedback, the market was mainlysee yesterday, which caused the overall transaction blocked, 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.Try to avoid using radiator copper pipes in hot water circulation pipelines to reduce the possibility of corrosion. If copper pipes are used as circulation pipelines, pipeline maintenance space should be reserved.When stacking, it shall be stacked reasonably and placed first.how,Four of the five major application fields of copper plate, copper bar and copper pipe: copper is used as various pipes, pipe fittings and decorative devices in the construction industry.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.The copper tube shall be heated and welded first,LillestromBronze plate, 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.

If you want to make the copper surface become bright again,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 but also quickly remove the rust and oxide layer on the copper surface to restore the luster of the copper itself.build, 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, 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, large manufacturers use copper units to buy a large number of copper pipes once we need not consider the preservation problem unless we buy a small amount at home. For example, 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.When installing, the copper pipe has the advantages of low transportation cost, easy maintenance and small space occupation.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.Lillestrom,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.Do not store too many other products, especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction.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.
