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.
遼寧省の部の鉄鋼工場は銑鉄を購入しようとしているが，現地の資源が逼迫しており，鉄鋼工場，オファーが高すぎて，需給の食い違いを招いた.江蘇，山東，山西，河北，河南などの地域では鋳鉄と球状インク鋳鉄の需要が低迷し，製鉄所の在庫圧力が高まっている.原材料価格の低下に伴い，製鉄所のオファーは低下し続けている.現在，需要とコストのサポートは弱く，プラスの上昇はありません.短期銑鉄市場は軟調で，変更は難しい.
ウルティラム銅管溶接プロセスは，優れた指向性，高強度，高単色性，高コヒーレンスなどの特性を有する銅管束を加工対象ワークの表面領域に する.銅管束が光学系によって集束された後，銅管と溶接対象物との相互作用によって，溶接対象の場所に高度に集中した熱源領域を短時間で形成することができる.ねつエネルギー溶接されるeaは溶融し，冷却し，結晶化してソリッド溶接点と溶接ビードを形成する.
鄭州の銅棒市場の価格は基本的に安定しており，出荷状況はよくない.管片について：今日の山東魯力管片はわずか元下がって，現在主流の出荷価格は-元です.配管工場側：臨沂配管工場は価格を週間ロックした.安定した市場心理により，熱間圧延シームレス鋼管の出荷価格は現在-元の間にある.市場面：閑散期になると，貿易商は通常高値で出荷します.補充は主に既存の在庫を維持し，大きな補充計画はありません.需要が低迷しており，鄭州の銅棒市場の価格は安定的に低下する見通しだ.
モンテテリオ以上のように，中長期政策と大環境，および瀋陽の現在の在庫水準に基づいて，東北地区市場は般的に悲観的である.銅排泄物の低在庫レベルは市場全体に動力を欠いている.当市の銅棒市場は今年はすでに停止しており，短期と中期的に改善するのは難しい.全体的に見ると，明日の瀋陽銅棒の市場価格は安定するかもしれない.

In August， the price of domestic medium and heavy plates fell sharply. As of August ， 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.
設置時には，銅管は輸送コストが低く，ウルティラム1060アルミニウムストライプ，メンテナンスが容易で，スペースが小さいという利点がある.
In terms of steel billets: at :， and the current carbon square billets were delivered with tax of yuan. After the th National Congress of the Communist of China， the market had doubts about the uncertainty of environmental production restriction and was still waiting for a clearer direction. Therefore， it can be seen that at this stage， there was no unilateral market for either futures or cash， and there was no definite pattern of ups and downs.According to the monitoring data of Lange Iron and Steels cloud business platform， as of the time of publication Tianjin Youwelded Line: the steel mill reported: Rongcheng # yuan/ton， B yuan/ton; Jiujiang # - # to Tianjin yuan/ton; The arrival price of Xinji Aosen # is yuan/ton， and that of B steel is yuan/ton; Jiyuan # yuan/ton， B steel yuan/ton; Fulen # yuan/ton; Weigang # yuan/ton， B steel yuan/ton.
設備のメンテナンスCopper pipe has the characteristics of and is the choice for the installation of water pipe，溶接効果が低下するため，サンドクロスやサンドペーパーを使用して清掃しないでください.
In view of the current overall price difference， the local copper bar price continued to rise at a high level today，ウルティラム5052アルミニウムストリップ， 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， the market price of copper bars in Shenyang is stable and the shipment is poor.
The application of copper tube The copper tube is generally used in the heat exchange equipment， and the low-temperature pipeline in the oxygen production equipment can also be used. Some relatively thin copper tubes can be used to transport some pressurized liquids， and can also be used as pressure measuring tubes in instruments; In addition the copper pipe is relatively firm， unlike other metals， which are easily corroded， so now many water pipes and refrigeration pipes used in buildings will choose to use the copper pipe.
どこにありますか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.
{} The excellent performance of copper pipe The welded copper pipe has the characteristics of firmness and corrosion resistance， which makes it a suitable choice for modern contractors to install the water pipe， heating pipe and refrigeration pipe in all residential commercial houses.
If the corrosion on the copper surface is found to be slight， it can be erased with linen copper wire， but it is not recommended to apply oil for preservation.
