私はありません銅管の保存方法がわかりません.
硬質銅管は延伸または押出後に人工的に処理されていないので，自然に形成することができる.この時点で，銅管の組織形式はいっぱいになっています.この銅管は割れやすく，曲がるのに適していない.そのため，硬銅管は通常まっすぐである.
自貢市And do a good job of data sorting.
Red copper bars in other regions basically follow the price trend of Tangshan， in which the bid of Jiangsu Steel Works tends to be higher， and most of the downstream prices are asked， and the overall market transaction is fair. The steel mills in Wuan are limited in receiving orders， and the market resources are tight. Most of the merchants are reluctant to sell. Shanxi billet market offers vary， and it is difficult to clinch a deal. The willingness of downstream customers to receive orders is weak， so they hold a cautious wait-and-see attitude. At prepresent， the steel market is in the "golden third" peak season. The market has a good expectation of the future market and a strong willingness to support prices. It is expected that the prices of Tangshan mainstream billets will be stronger next week.
ティアサレFour of the five major application fields of copper plate， copper bar and copper pipe: copper is used as various pipes， pipe fittings and decorative devices in the construction industry.
The simplest way is to use copper cleaner. Brass， red copper， bronze， etc. can be used. Oil stains， fingerprints， oxide layers，Wu安，江陰，楽従，在庫レベルは比較的温和を維持し，市場の圧力は相対的に小さい.Wu&# ;データによると月日現在，呉市中厚板の総在庫量，anは万トンに近く，毎週トン増加している.月下旬には，年内に万トン減少し，春節後の 高水準から万トン低下し，週連続で上昇した.ovについて言えば数は，比較的穏やかなレベルに保たれていると言うべきだ.
銅管は非鉄金属管であり，頑丈で耐食性がある.環境温度に比べて割れないため，すべての住宅商品住宅に水道管，熱供給管，冷房管を設置することが現代の請負業者の第選択となっている.
When the copper tube is heated and the flux melts into liquid， place the preheated electrode on the welding point immediately. As soon as the electrode begins to melt， move the flame nozzle back and forth until the solder flows into the gap between the two tubese the flame， and then remove it after a few seconds. If it is suspected or found that there is still a gap between the two pipes. It can be heated again to make the flame nozzle move continuously at two points. A small amount of solder can be added.

以上のように，現在の現物市場価格が商店の予想冬貯蔵価格よりはるかに高く，需給圧力が徐々に現れ，原材料の支持力がないなどの要素の影響を受け，その中で市場需要の収縮の影響が大きい.そのため，短期的には現物建材が大幅に上昇する可能性はなく，建材価格は主に揺れ運転を主とする可能性があるが，需要が萎縮するにつれて需給圧力が顕著になるが，冬季貯蔵などの影響を考慮すると，業者は月に現物価格を下げる可能性がある.
月，国内の中厚板価格は大幅に下落した.月日現在，月末より元/トン下落した.今月初め，マクロ的な悪いニュースや 近のファンダメンタルズの不振の影響を受けて，自貢市アルミニウム板，市場心理は悲観的になり，部のトレーダーは低価格で出荷した.市場在庫が上昇し，自貢市1060アルミニウムストライプ，在庫圧力が高く，在庫不足現象がなくなり，市場取引の雰囲気が冷淡で需要表現は持続的に下落し，現物価格は圧力を受けて下落した.
Today， the price of tube billets is up and down. At present， Jiangxin hot rolling is yuan， continuous casting yuan is down yuan， Dongfang hot rolling yuan is down yuan， Luli hot rolling yuan is down yuan， Tiangang hot rolling an is down yuan， production is stopped in mid January， Weigang hot rolling yuan is up yuan， continuous casting yuan is up yuan， Huaigang yuan is up yuan， Zhongtian yuan， Changqiang yuan， Linggang yuan.
ターゲット方，製鉄所では，製鉄所のロック価格が下落しており，受注状況は芳しくない.この製鉄所の生産能力利用率は低いが，市場は依然として供給過剰である.製鉄所の在庫と現物在庫が上昇しているそのため市場価格は大幅に下落した.その後，先物市場は反発し現物価格も上昇した.瞬にして大量の取引が発生した.しかし，ブラック先物の下落に伴い，市場の取引量は大幅に縮小した.また，在庫圧力が大きく，貿易商は低価格で出荷し，現物価格は下落に耐えた.中厚板の落下防止能力が高いため，落下幅と速度はねじ山より小さい.
After welding， it can be annealed at ~ ℃ to prevent "self cracking" by stress.
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， and the current mainstream ex factory price is - yuan. In terms of pipe plant: Linyi Pipe Plant locked the price for a week. With a stable market mentality， 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， and the market price of Zhengzhou copper bar is expected to be stable and declining.
自貢市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.
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 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.
In addition， it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures， so copper pipes need to be selected for many times in other places.
