Although the opening continued the weak trend, the intraday transactions improved, and the prices of some copper bar manufacturers rose. From the specific situation, although the manufacturer feedback that the shipment is average, the mentality is relatively calm, the market inventory is not much, the transaction of strip steel is better than other steel varieties, and the downstream mainly focuses on callback buying without panic inventory clearing. It can be seen that although the steel market continues to shake, the overall demand for strip steel remains in a good state.Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.Helen,Methods of copper pipe anti-corrosion Strengthen scientific research.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.Alausi, 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.In the morning trading today, 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.To sum up, due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants,HelenAluminium tube,HelenH65 brass plate, the gradual emergence of supply and demand pressure, and the weakness of raw material support, among which the contraction of market demand has a greater impact. Therefore, the author believes that in the short term, the spot building materials do not have the possibility to rise significantly, and the price of building materials may mainly operate in shock, but with the shrinking demand, the supply and demand pressure becomes prominent, However, considering the influence of winter storage and other factors, it is still possible for merchants to lower the spot price in November.

Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.If the environment is wet, steel mills in some northern cities implemented production restriction, and some domestic economic data improved, which boosted manufacturers confidence. Today, steel prices generally rose. However, with the approaching meeting and the rainfall in the south caused by the typhoon, the construction progress of the downstream construction site is affected which is not conducive to the continuous demand. The high spot price transaction today is weak,Helen310s stainless steel round steel, which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow, and some businesses may reduce prices and take goods.install,Disadvantages: Due to loose tissue and high pressure resistance, the elongation is ~% pipe fittings and decorative devices in the construction industry.The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm copper bar and copper pipe: copper is used as various pipes, and the Brinell hardness (HB) is ~

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.Professional is king,The application of copper tube The copper tube is generally used in the heat exchange equipment, and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids, and can also be used as pressure measuring tubes in instruments; In addition, the copper pipe is relatively firm, unlike other metals, which are easily corroded, so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.Copper pipes of different models shall be stacked separately.First of all, 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.Helen,antages: low production cost and high production efficiency.First of all, 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.I don t know how to keep the copper tube.
