So far as the storage method of copper materials is concerned, we should properly keep the copper products we buy extend the service life of copper and ensure its performance to avoid unnecessary losses.When placing, they should be stored separately according to the different components, and should not be mixed together. The copper surface may have electrolytes, so it will react, especially with other materials such as rubber, which has a large impact.Mondro,For internally threaded tubes with the same inner diameter, the thickness of feus metal is not required for copper tubes.Save materials and total cost, stability and performance, and can save maintenance.Takanini,Three of the five major application fields of copper plate, copper bar and copper tube: copper is used to manufacture, - tons of copper are needed.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, 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.At the opening this morning, the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform, the same below), the * mm copper bar was yuan, and the * mm copper bar Henan copper bar was yuan.

Do not store too many other products, especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction.Regularly inspect and monitor the copper pipe to reduce the loss caused by copper pipe corrosion.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,Mondro6063 aluminum tube, 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.Administration,It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found,e the sleeve on the pipe to evenly apply the flux on the joint, and confirm that the pipe is inserted into the bottom of the socket, then wipe off the excess flux, and the joint is assembled and can be heated.The copper bar market declined steadily this week, with a decline of - yuan. Due to low pig iron inventory, some steel mills in Jiangxi have resumed purchasing recently, but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently, the steel market has been in shock and adjustment, and the merchants are unstable. Steel mills in Hebei,Mondro310s stainless steel coil, Tianjin and other regions have stopped producing pig iron for steelmaking. Now, it is mainly expected to make inquiries. However, due to the lower price of raw materials, the price of iron mills has been lowered.

Copper pipe has the characteristics of, and is the choice for the installation of water pipe, heat supply and refrigeration pipe.demand,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,Mondro40cr alloy steel plate, the market was bleak.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.It can be wrapped with moisture-proof paper for moisture-proof protection. It can also prevent oxidation to a certain extent. If cracks or serious corrosion are found, they must be isolated.Mondro,If you want to avoid this kind of situation for a long time, you can choose passivation treatment. In this way, not only is the copper surface serious, it can be cleaned under normal circumstances, but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment so this effect is very good.The composite method of three production methods of copper tube is also a high-tech production method for this method. It is a copper material containing impurities. Those copper materials, and then the material is purified to produce copper tube materials.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.
