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，ピャーポン2507ステンレス鋼板， 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， and the merchants are unstable. Steel mills in Hebei， 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.
Safe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals， has good toughness and high ductility， and has excellent anti vibration， anti impact and anti frost expansion properties.
ピャーポンUse qualified copper raw materials for production， try to avoid using the pipe body produced by recycled copper， reduce impurity corrosion， and extend the service life of copper pipe.
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.
EbayeAt the opening this morning， the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform， the same below) the * mm copper bar was yuan， and the * mm copper bar Henan copper bar was yuan.
For small diameter pipes， when using filler metal， the length of filler metal is allowed to be equal to the diameter of the pipe， which is enough to fill the weld crater. One of the five major application fields of red coppr plate T， red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries， accounting for more than half of the total consumption. Used for various cables and wires， motors and transformers， switches and printed circuit boards; In the manufacture of machinery and transport vehicles， it is used to manufacture industrial valves and accessories， instruments， sliding bearings， heat exchangers， pumps， etc.
日中後期には，先物価格の上昇や武鋼の生産制限政策の増加などの朗報があったにもかかわらず，在庫レベルが高いため，貿易商は値上げの意思がなく，彼らの多くはすでに出荷されており，現物価格は上昇の動力に欠けている.市場在庫が大幅に増加した.当時，邯鄲の市場在庫は節後に高い水準に達した.長期的な低迷した需要表現は市場の供給過剰を招き，在庫の上昇が続いて市場の心理状態が空虚になった.
材料と総コスト，安定性，パフォーマンスを節約し，メンテナンスを節約できます.
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， 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， 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 with a small processing range， 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，ピャーポン310 sステンレスシームレス管，ピャーポン321ステンレス鋼円鋼， 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.
赤銅板T ，赤銅列，赤銅管のつの応用分野の：銅は化学工業業界に広く応用され，真空容器，蒸留タンク，醸造タンクなどの製造に用いられる.
販売促進まず倉庫を建設しなければなりません.倉庫内の温度は通常-°に維持しなければならない.C，湿度は正常でなければならない.部屋は換気を保つべきだ.
溶接工具のノズルは熱が集中しすぎないように小さすぎてはいけません.
Disadvantages: Due to loose tissue and high pressure resistance， the pipe is only used to produce small air conditioning copper rods.
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.
誠実と信用をもって経営するWith the advent of heating season， the raw material support of red copper row is weak. Under the influence of heating season and environmental protection production restriction， steel mills in some regions began to implement the production restriction measures for blast furnaces in heating season， and the demand for iron ore was weakened. In addition， the production restriction policy was issued in Tangshan today. From : on October to : on October ， the production restriction measures specified in this Notice were implemented.
Avoid discoloration of coil surface due to pollution， and control the composition of auxiliary materials such as lubricating oil and cleaning agent. The supplier is required to provide technical performance indicators such as viscosity， flash point， acid value and distillation range， and the third-party test report of elements harmful to copper tubes. In the rewinding process， strengthen the cleaning of the copper tube surface to reduce the residue of lubricating oil on the copper tube surface.
現在の全体的な価格差を考慮すると，今日も現地の銅棒価格は引き続き高位に上昇しているが，華東地区以外の地域では明らかな後続の動きは見られず現地価格は依然として東北と華中地区の価格差との優位性を持っている.生産制限の影響で現地の後続商品量が少ないため，現地の在庫圧力はさらに低下し，銅棒の価格支持は依然として強い.しかし，現在，国内の不動産規制は引き締められている.市場&## ;市場の将来の需要に対する予想は弱まっている.今日，瀋陽の銅棒の市場価格は安定しており，出荷量はよくない.
ピャーポンTo 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， and the price of building materials may mainly operate in shock， 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.
