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,Cornella de Llobregat Stainless steel plate, 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 hard copper tube is not artificially treated after being drawn or extruded, so that it can be naturally formed. At this time, the organizational form in the copper tube is full. This kind of copper tube is more likely to crack and is not suitable for bending. Therefore, the hard copper tube is generally straight.Cornella de Llobregat Standardized design.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, 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.Santo Andre,The production method of soft copper tube is basically the same as that of hard copper tube, that is, the annealing process is added compared with the hard copper tube. Annealing of copper tubes means that they are calcined in a high temperature furnace to change the arrangement of the elements in the copper tubes. However, after annealing, the copper tubes will become soft, which makes it easier to bend. The copper tubes produced in this way are called soft copper tubes.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 market price of Zhengzhou copper bars is basically stable, and the shipment is not good. In terms of tube blank: today, Shandong Luli tube blank slightly reduced by yuan, the factory price of hot rolled seamless pipes is now between - yuan. On the market side: with the arrival of the off-season, traders generally ship goods at a high price. Replenishment is mainly to maintain the existing inventory, and there is no large replenishment plan. The demand is sluggish, it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.Methods of copper pipe anti-corrosion Strengthen scientific research.However, Tangshan Iron and Steel Group Co., Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits, or to lay hidden dangers for the decline. As far as tomorrow is concerned, the price may still maintain a narrow range of shock operation pattern.Information recommendation,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.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.When welding, just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.

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, industrial facilities and other places begin to use ground heating radiator, 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.property right,Cornella de Llobregat GCR15 alloy round steel,If you want to make the copper surface become bright again, you can polish it with copper point solution. It can not only make the copper surface brighter, but also quickly remove the rust and oxide layer on the copper surface to restore the luster of the copper itself.Corrosion of copper in humid air is a chemical reaction, which makes coppeer look ugly. The above operations will make copper tubes beautiful. Bright brass tubes are still common in today s daily life and will be used in many places. But even with such a common product,Cornella de Llobregat 12cr1mov alloy round steel, many people still do not understand its performance characteristics. So what are the excellent performance characteristics of this product? Here is a brief introduction to this article.Red copper inventory in key areas has risen continuously, 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.Cornella de Llobregat ,The conductive production of copper tube is the latest method for this method. It is the production of nanocrystalline copper materials with conductivity. Because this raw material is very special it is a copper material produced by using nanotechnology, and copper ions can be separated by conductivity, so that copper tubes can be produced with the separated copper ions. This method is very complex, requires high technology and new equipment, so only advanced foreign countries can use this production method.[] Welding process of copper pipe Clean the end and seven ports of steel pipe with steel wool. Do not use abrasive cloth or abrasive paper to clean, because it will affect the clean interface and result in poor welding effect.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
