On October , at the end of September , Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel, and all the de capacity equipment had been shut down and withdrawn. On October , 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.The copper bar market declined steadily this week, with a decline of - yuan. Due to low pig iron inventory, 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 Tianjin and other regions have stopped producing pig iron for steelmaking. Now, due to the lower price of raw materials, the price of iron mills has been lowered.Hogana,As theation effect of copper material on the agent is weak, the dissolved oxygen and air bubbles in it will corrode it.Do not store too many other products, especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction.Kerkrade,Three of the five major application fields of copper plate, 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.Let s elaborate on the advantages of copper pipe materials: copper pipe floor heating refers to a heating method that uses hot water as the thermal medium, circulates in the copper pipe heating pipe, heats the floor, and heats the floor through the ground in the form of radiation and convection heat transfer. I. The copper tube has fast heat dissipation effect and strong heat resistance. Even under the condition of high temperature water supply, the service life of the floor heating tube will not be affected. Two. Copper pipe is a metal pipe,o it is not easy to scratch. Therefore, it is not easy to leak. Three. High temperature resistance, high pressure resistance, relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.Hygiene and health: various modifiers, additives, additives and other chemical components of plastic pipes in copper pipes.

Insert the pipe into the top of the bayonet,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.Water with low PH value causes corrosion.Overview of three production methods of copper tube Copper tube is a very important material for copper materials. There are many ways to complete the production of this copper tube. For copper pipes, the following three methods are generally used to produce materials. The copper tubes produced by these three methods are not only very good in performance, but also very convenient to operate. There are three production methods for copper tube, so what are the three production methods for copper tube?The cheapest,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, Tianjin and other regions have stopped producing pig iron for steelmaking. Now, due to the lower price of raw materials, the price of iron mills has been lowered.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, copper alloys and composite copper materials are put together by electrochemical reaction to produce a nanocrystalline copper material, and then the material is purified to produce copper tube materials.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,Hogana6082 aluminum bar, 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 tube is a kind of nonferrous metal tube, which is pressed and drawn seamless tube. The copper pipe has good thermal conductivity, and is solid and corrosion resistant. It will not crack when compared with the ambient temperature, so it becomes the first choice for modern contractors to install the water pipe, heat supply pipe and refrigeration pipe in all residential commercial houses.Inspection environment,Red copper inventory in key areas has risen continuously, but the total pressure is not big. From the current overall inventory situation of the main distribution centers Wu an, Jiangyin and Lecong, the inventory level remains relatively moderate,HoganaBronze plate, and the pressure on the market is relatively small. In Wu an market according to the data, the total inventory of medium and thick plates in Wu an was close to tons as of May , increasing by tons on a weekly basis. In late April, it reached tons lower in the year, down tons from the high level after the Spring Festival and rose for three consecutive weeks. In terms of the ovquantity, it should be said to maintain a relatively moderate level.The storage and transportation of copper tubes in summer should also be paid attention to when controlling the surface of copper tubes.In addition, it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures,HoganaAlloy plate, so copper pipes need to be selected for many times in other places.Hogana,Save materials and total cost, stability and performance, and can save maintenance.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.In August, the price of domestic medium and heavy plates fell sharply. As of August , the price center of ordinary carbon boards in leading cities had dropped to , down yuan/ton from the end of July. At the beginning of the month, affected by the macro bad news, and the recent poor performance of fundamentals the market mentality turned to pessimism, and some traders shipped at low prices. The market inventory rose, the inventory pressure was high, the stock shortage phenomenon disappeared, and the market transaction atmosphere was cold, and the spot price fell under pressure.
