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.

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.

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.
Air conditioning copper tube production technology Upward lead method: This production method is electrolytic copper after copper tube is directly melted.

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 the first ten days of May，덕 반7075 알루미늄 막대， the overall order receiving quantity of Tianjin Hebei Henan Plate Plant was not ideal. According to the monitoring data， 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， while at the end of April， the elongation is ~%， and the Brinell hardness (HB) is ~
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.

덕 반To sum up， due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants， the gradual emergence of supply and demand pressure， and the weakness of raw material support among which the contraction of market demand has a greater impact. Therefore， the author believes that in the short term， the spot building materials do not have the possibility to rise significantly， but with the shrinking demand， the supply and demand pressure becomes prominent However， considering the influence of winter storage and other factors， it is still possible for merchants to lower the spot price in November.
In August， the price of domestic medium and heavy plates fell sharply. As of August ，덕 반주석 도금 동봉， 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， the demand performance continued to decline， and the spot price fell under pressure.
