Copper pipe has the characteristics of, and is the choice for the installation of water pipe, heat supply and refrigeration pipe.Remove the flame. If the filler metal does not melt, continue to heat the joint and try again. The melted filler metal is sucked into the casing port according to the capillary effect until a complete filler metal ring appears on the casing port. Remove the flame Pay special attention not to let the flame directly contact the filler metal. It should be the heat at the joint that melts the filler metal. In order to clean the copper pipe, the welding flux must have a degree of corrosivity, and shall be cleaned after brazing. The so-called & quot; self-cleaning& quot; fluxes are generally not recommended because of their corrosivity.Surabaya,The storage and transportation of copper tubes in summer should also be paid attention to when controlling the surface of copper tubes.The simplest way is to use copper cleaner. Brass, red copper, bronze, etc. can be used. Oil stains, fingerprints, oxide layers, etc. on the surface can be cleaned with copper cleaner first.NATO,Advantages and scope of application of copper tube ground heating At present, ground heating is not only a comfortable heating method, but also a symbol of modern life quality. More and more houses, public buildings, sports facilities, which is an important part of ground heating. Due to the corrosion resistance of copper, copper tubes are selected as the main material of radiator in many places.In Jiangyin market, another distribution center, the overall inventory of the current circulation link is about tons, slightly lower than the normal level. At the beginning of this week, the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However, from the perspective of the policy port of the steel plant, the overall production situation of Nangang, Hengrun, Dada, etc. is relatively normal, and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons, which is a medium normal level, and the recent spot price of Lecong market has a large gap with that of the north.Do not store too many other products especially other acid materials and alkali materials, in the warehouse to prevent mutual reaction.

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.For the production and processing of sculpted copper tubes, the sheet metal shall be first opened in the sheet metal workshop according to the dimensions shown in the drawings, which is commonly referred to as opening. Then cut the corners of these open sheets according to the height of the edge, and then use the bending machine to form the edge according to the drawing forming diagram. The shaped copper pipe shall also be installed with reinforcing ribs as required, and the four corners of the shaped plate shall be welded well. The welded parts shall be sent to the grinding workshop, and the spraying surface shall be polished and the welding interface shall be polished and leveled. The polished modeling copper pipe is then sent to the spraying workshop for processing. Before spraying, the surface of the sculpted copper pipe shall be chrome treated and the process hole shall be drilled, so as to ensure that the sculpted copper pipe can be hung on the spraying line well, and the painting can be smooth without flow marks,SurabayaT2 copper bar, and the color is consistent without color difference. After that, according to customer demand, the qualified products are pasted with protective film and bound with bubble film or wooden box.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.Administration,SurabayaStainless steel coiled plate,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, with the decline of black futures, the market transaction volume shrank significantly. In addition, 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.In consideration of the above factors, more and more steel plants have stopped production since October, and the production limit in Wu an and Tangshan heating seasons has been advanced. In addition, the formal implementation of production limit in & quot; +& quot; urban heating seasons after November by steel enterprises, the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high, and the willingness to further replenish the inventory is not strong. In terms of supply, the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection, the quantity of * * * is relatively limited. In general, the short-term iron ore market may lack upward momentum.After the pipe is cleaned, the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately, so that dust and dirt will not pollute the capillary gap.

At the opening this morning, the current market price of * mm Linyi copper bar was yuan (ton price, the same below), the * mm copper bar was yuan, and the * mm copper bar Henan copper bar was yuan.ranking,Surabaya12CR1MOV alloy plate,The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.When cutting the copper pipe of air conditioner, rather than fixing it by hand, to preveshaking and resulting in irregular cutting. After the cutting of the air conditioner copper pipe is completed, and then processed again after cooling, otherwise oxidation will occur due to high temperature. Liu Shuchen, director of the Resource Analysis Office of the Information Center of the Ministry of Land and Resources, said that copper bar manufacturers are currently in a period of adjustment in China s mining industry as a whole. In the long run, the mining super cycle driven by China s demand has not changed, the global mining industry will rise again, and the W-shaped trend will fully emerge. In the second half of the year, there were signs of stabilizing and rebounding. In terms of the macro factors affecting the bulk commodities the factors affecting the European market of tinned copper bars have gradually weakened, and the economic conditions of China and the United States have become the key factors affecting the bulk commodities. The European economic recession is a foregone conclusion, and the possibility of a crisis in the next period of time is also reduced. In recent years the American market economy has shown the characteristics of better than expected in the first quarter and weaker than expected in the second quarter. Since January, the global price of medical copper tubes has gradually got rid of the main tone of this year s shock and decline. & amp; quot; Air conditioning copper tubes show signs of stabilizing and rebounding. The three-month copper on the London Metal Exchange once rebounded nearly % from the year s low point, and the market price has rebounded to around dollars per ton. Driven by this products including aluminum, zinc and other products have also rebounded. Only nickel a basic metal product, has remained weak.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 Ruigang Lianlian, yuan for Baoda yuan, yuan for Meixin yuan, and yuan for Taizong yuan.SurabayaThe blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.Copper pipe has the characteristics of, and is the choice for the installation of water pipe, heat supply and refrigeration pipe.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.
