the same below) yuan, yuan for Jin Zhengyang yuan, yuan for Ruigang Lianlian, yuan for Baoda yuan yuan for Meixin yuan, and yuan for Taizong yuan.Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.Kampong Baharu balagon,{} The copper pipe welding can be divided into soft welding and hard welding. The soft welding temperature is lower than ℃, and the hard welding temperature is higher than ℃. Hard welding is usually used for silver, gold, steel, copper and other metals. Its welding points are much stronger than soft welding, and its shear strength is - times that of soft welding.The room temperature tensile strength of the annealed red copper sheet is ~ kgf/mm, the elongation is ~%, and the Brinell hardness (HB) is ~Media-Luna,In view of the current overall price difference the local copper bar price continued to rise at a high level today, while the regions outside East China did not show an obvious follow-up trend, and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction, and the price support of copper bar is still strong. However, at present, domestic real estate control is still being tightened. The market s expectation of future demand is weakening, and the market s fear of heights appears after the price rises. Today, the market price of copper bars in Shenyang is stable and the shipment is poor.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.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.

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, so copper pipes need to be selected for many times in other places.Hot water accelerates the corrosion of copper pipes.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 copper will be damaged. Many people do not know how to treat the copper surface? Now let the staff answer for you.Service first, which makes it a suitable choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial housing.If the corrosion on the copper surface is found to be slight, it can be erased with linen copper wire, but it is not recommended to apply oil for preservation.First of all, we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C, high production cost and high price. Extrusion copper tube process is a stable and excellent copper tube production method at home and abroad at present. Only the copper tubes produced by this process are more suitable for the field of heating and ventilation, which is the development direction of copper tube industry in the future.Good quality,Do not store too many other products,Kampong Baharu balagon45 # round steel,Kampong Baharu balagonbrass plate, especially other acid materials and alkali materials,Kampong Baharu balagonQ345D alloy round steel, in the warehouse to prevent mutual reaction.Standardized design.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.Kampong Baharu balagon,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, we should properly keep the copper products we buy, extend the service life of copper and ensure its performance to avoid unnecessary losses.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 and the pressure on the market is relatively small. In Wu an market, according to the data, as of May , the total inventory of medium and thick plates in Wu an was close to tons, 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.
