The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm, the same below) yuan, yuan for Jin Zhengyang yuan, yuan for Baoda yuan, yuan for Meixin yuan, and yuan for Taizong yuan.The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.Olsen,To prevent the copper pipe surface, the humidity of the packaging materials should be well controlled, and the moisture content of all wood and paper packaging materials should be strictly controlled below %. Each plate of material is tightly packed with PE film to avoid the copper pipe absorbing moisture from the outside.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.Poetic Wizard,Because of the characteristics of copper itself, it is very easy to rust and corrode in places with high ambient humihumidity. If we often use it, the problem will be smaller but if it is placed for a long time, the price of domestic copper bar fell. According to the monitoring data of Lange Steel s cloud business platform, the average price of * mm hot rolled strip in key cities in China is , 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.

antages: low production cost and high production efficiency.Disadvantages: The pipe structure is loose, and it is not resistant to high pressure. It is only suitable for the production of small air conditioning copper pipes.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, 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,OlsenT2 copper plate, 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.Direct labor,At present, the fundamentals faced by the domestic copper bar market are still mixed. On the one hand, the market supply is expected to shrink, but on the other hand, the northern market has entered the off-season of demand, and the market s expectation of future demand is pessimistic. In the short term, domestic steel prices will enter the operating track of range consolidation. To sum up, considering the current situation of demand and inventory in the steel market it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching, and black series speculation is still taking place. But personally environmental protection phenomena such as steel mills are still going on, the fluuation range of the market in this region is limited, and businesses can operate flexibly on a short-term basis, and the shipment transaction is * * *.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, Henan, Liaoning, Shandong and other regions has increased. In addition, with the gradual release of downstream demand,Olsen310s stainless steel seamless pipe, 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.I don t know how to keep the copper tube.

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, the use of copper tubes is very common. What are the differences between hard copper tubes and soft copper tubes in the use process? What are the differences between the two in terms of specific applications?Equipment maintenance,On October , at the end of September , the Development and Reform Commission of Handan City released the Plan for Handan City to Eliminate Excess Iron and Steel Capacity. Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.When heating steel pipes and all the de capacity equipment had been shut down and withdrawn. On October , the temperature is slightly higher than when heating copper pipes.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.Olsen,To sum up, the market in Northeast China is generally pessimistic based on the medium and long-term policies and the general environment, as well as the current inventory level in Shenyang. The low inventory level of copper platoon makes the whole market lack of motivation. The copper bar market in this city has stopped this year, and it is hard to improve in the short and medium term. On the whole, the market price of Shenyang copper bars may be stable tomorrow.In the first ten days of May,Olsen321 stainless steel coiled plate, 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.Save materials and total cost, stability and performance and can save maintenance.
