the continuous decline of iron ore port inventory may end. In addition

Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand according to the new statistics of * *, 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,Maya321 stainless steel round steel, 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.Maya,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.Disadvantages: low output, which is the development direction of copper tube industry in the future.Shizuoka,Disadvantages of copper pipe As far as copper pipe is concerned, high production cost and high price are its biggest disadvantages. Compared with other pipe fittings, the cost of copper pipe is much higher, and the connection at the copper pipe interface requires high construction technology level.The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm, the elongation is ~%, and the Brinell hardness (HB) is ~The excellent performance of copper pipe The copper pipe has the characteristics of and, heating and cooling pipes in all residential commercial housing.

Generally, oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.Therefore, it is often used in some ah heat exchangers to Kazakhstan oxygen equipment.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, and the mainstream manufacturers prices fell today.Quality assurance,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.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.Disadvantages: Due to loose tissue and high pressure resistance, in the steel plant, the lock price of the steel plant has been falling all the time, and the order receiving is poor. The capacity utilization rate of the steel plant is low, but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising, so the market price has fallen sharply. Subsequently, the futures market rebounded in a wave, and the spot price also increased with the increase. There was an instant of large volume of transactions. However, with the decline of black futures, the market transaction volume shrank significantly. In addition, the inventory pressure was high, traders shipped at low prices, and the spot price fell under pressure. Due to the strong drop resistance of medium and thick plates, the drop amplitude and rate are less than those of threads.Where can I find it?,It is said that due to the optimistic future and tight resources, some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well, and the price of raw materials has risen, so the iron price has risen. The iron mills have a high enthusiasm for producing steel, so there is not much cast iron resources, and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting, and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand, the pig iron market is performing well and is expected to continue to operate strongly in the short term.As theation effect of copper material on the agent is weak, the dissolved oxygen and air bubbles in it will corrode it.According to * * new data, in September , China s imported iron ore * * * broke through the million ton mark, reaching million tons, a record high; From January to September, China s iron ore import increased by % to million tons, and the annual import volume is expected to exceed billion tons. However, judging from the shipment of imported ores after the National Day, due to the rapid declinecline in iron ore prices, the iron ore price index once fell below $, which reduced the enthusiasm for the shipment of imported ores. In addition, environmental protection inspection has become stricter, and the supply of some domestic mines has been greatly affected. The current operating rate of domestic mines is percentage points lower than the previous peak, which is likely to decline further in the future.Maya,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,Maya45 # round steel, 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.On the other hand, in the steel plant, the lock price of the steel plant has been falling all the time, and the order receiving is poor. The capacity utilization rate of the steel plant is low,Maya7075 aluminum bar, but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising, so the market price has fallen sharply. Subsequently, the futures market rebounded in a wave, and the spot price also increased with the increase. There was an instant of large volume of transactions. However, with the decline of black futures, the market transaction volume shrank significantly. In addition, the inventory pressure was high, traders shipped at low prices, and the spot price fell under pressure. Due to the strong drop resistance of medium and thick plates, and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.
