Disadvantages: low output， 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.
It has excellent conductivity thermal conductivity， ductility and corrosion resistance.
카드 양.One oftion of copper tubes. The common wave shape is a single copper tube. Hyperbolic means that two different arcs overlap on the same surface， that is， starting from different circle centers， draw arcs in two radii. The red copper tube is a module made of double curves designed according to the drawings. The red copper tube is light in weight， good in rigidity and high in strength. The shapes of the red copper tubes processed are different and can be processed into various geometric shapes such as arcs and spheres. It is beautiful， elegant and colorful. Lets talk about the two main methods of processing and forming the copper tube: The hot processing and forming method is to roll the copper tube to a roughly hyperbolic shape， then heat it， then place it on the mold prepared in advance， then slowly beat it with a hammer， finally cut， weld， fold polish and polish it. The whole process needs to be very careful to ensure the surface quality of the copper tube. This forming method is very suitable for parts with small model and large arc change. When the model size is relatively large and complex， it can be considered to break it into small pieces for forming， and then splice it into large pieces. For such copper pipes， the cost is high and the production period is long. Forming method of roll bending This method is to make some modifications on the roll bending machine， and change one of the shafts into a concave type and the other into a convex type. This method can form a regular copper tube like a sphere， with a small processing range， but it has great advantages for copper tubes with small radians. What problems should be paid attention to when designing the hyperboloid copper tube? Everyone knows that the design of the air conditioning copper tube is very important. To achieve the beautiful shape， exquisite workmanship and fashionable personality of the hyperboloid copper tube， first of all， the design is very critical. Some small copper tube copanies are not mature enough in design and have not enough design experience， so they often have problems in design Hyperbolic copper tube is very famous for preparing some details that we should pay attention to in the design. The sculpted copper tube is highly decorative， and the production and processing technology of hyperbolic shaped copper tube is relatively complex. Copper tube products with strong aesthetics. According to the design requirements， different shapes need to be molded for the sculpted copper tube， so the production process of sculpted aluminum veneer is relatively complex.
In consideration of the above factors， more and more steel plants have stopped production since October， and the production limit in Wuan and Tangshan heating seasons has been advanced. In addition， the formal implementation of production limit in "+" 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.
테 트.However， 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，카드 양.310s 스테인리스 강판， 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， the price may still maintain a narrow range of shock operation pattern.

[] 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.
It has excellent conductivity， thermal conductivity， ductility and corrosion resistance.
Welding sequence of copper pipe Before heating， apply the flux to the position to be welded.
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.

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， the filler metal shall melt.
In the first ten days of May， the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak. Due to the weak market shock， the overall order intake of the spot steel market was relatively weak. The total quantity of orders received in the first ten days of May is only about tons， while at the end of April， the total quantity of post settlement agreements of main steel plants can exceed tons.

According to the feedback， the market was mainlysee yesterday， which caused the overall transaction blocked， and the mainstream manufacturers prices fell today.

The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently， the terminal demand has also shrunk due to the sudden drop in temperature， causing a weak shock. According to the communication with local traders in Cangzhou， various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks， which is better in the off-season， and the shipment of some specifications has improved. However， the trading atmosphere in the small and medium-sized pipe market is still cold， and the demand is slowing down gradually. To sum up， it is expected that the market price of Cangzhou seamless pipe will be stable and weak in the near future.

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 markets expectation of future demand is weakening， and the markets fear of heights appears after the price rises.Today，카드 양.2507 스테인리스 강판， the market price of copper bars in Shenyang is stable and the shipment is poor.
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.
