The second of the five application fields of red copper plate T， red copper row and red copper tube: copper is widely used in the chemical industry to manufacture vacuum vessels，新しいクズネツク304ステンレスパイプ， distillation pots， brewing pots， etc.
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， 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.
新しいクズネツク外装は表面の傷，亀裂，その他の損傷を防ぐことができます.
管片価格の調整と引き下げは，新しいクズネツクGCR 15合金丸鋼，主に環境保護の生産制限と温度と天候への需要が弱いためである. 近では，端末の需要も気温の急降下で萎縮し，弱い揺れを引き起こしている.滄州の地元貿易商とのコミュニケーションによると，先週の様々な朗報により，過去週間の滄州熱膨張管の出荷量が増加し閑散期にはさらに良くなり，部の規格の出荷量も改善された.しかし，中小型パイプライン市場の取引雰囲気は依然として冷淡で，需要は徐々に鈍化している.以上のことから， 近の滄州シームレス鋼管市場の価格は安定して弱体化する見通しだ.
カマナRed copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand， the continuous decline of iron ore port inventory may end. In addition， according to the new statistics of * *， the available days of imported iron ore of steel mills are days， which is one day lower than that before the National Day， and is on the high side of history. The steel mill said that at present， the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction， the steel mill is not willing to replenish the inventory.
銅管溶接プロセス用鋼線綿洗浄鋼管の端部とつのポート.清掃界面に影響を与え，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.
When welding， just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.
Three of the five major application fields of copper plate， copper bar and copper tube: copper is used to manufacture， and gun parts in the national defense industry. Every million rounds of copper are produced， - tons of copper are needed.
多くの人は使用過程と生産方法の中で銅管の貯蔵方法を完全に理解していない.
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.
総合品質管理それは優れた導電性，熱伝導性，延性と耐食性を持っている.
積み上げる時，新しいクズネツク20 CrNiMo合金鋼板，合理的に積み上げ優先的に置くべきである.
In the middle and late ten days， although there were good news such as the rise of futures and the increase of production restriction policy in Wuan region， due to the high inventory level， traders had no desire to increase prices， most of them had shipped goods， and spot prices lacked motivation to rise. The market inventory rose significantly. At that time， the market inventory in Handan reached a high level after the festival. The sluggish demand performance for a long time led to the oversupply of the market， and the continuous rise of inventory led to the empty market mentality.
Extrusion method: This production method is to cast copper ingots after smelting， because it will affect the clean interface and result in poor welding effect.
As the inner wall of the pipe rubs with water， its film is damaged， resulting in erosion corrosion. The higher the water pressure， the greater the flow， and the more serious the corrosion.
安全で信頼性が高い：銅管は金属管と非金属管の利点を結合している.プラスチック管よりも硬く，通常の金属の高い強度を持つ（冷抜銅管の強度は同じ硬度を持つ鋼管に相当するess）；それは普通の金属よりも曲げやすく，良好な靭性と高い延性を持ち，優れた耐振動，耐衝撃，耐凍結膨張財産を持っている.
新しいクズネツクそれは優れた導電性熱伝導性，延性と耐食性を持っている.
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
見通しが楽観的で資源が逼迫しているため，部の製鉄所ではしばらく受注しないという.遼寧省の製鉄所は鋼材購入の意欲を高めた.製鉄所の納品が好調で原材料価格が上昇したため，鉄鉱石価格が上昇した.製鉄所は鉄鋼の生産意欲が高いため，鋳鉄資源が少なく価格も上昇した.唐山の部の製鉄所では製錬用に少量の鋼材が調達され始めており，多くの製鉄所ではまだ様子見が続いている.コスト増加と需要の逐次放出を背景に，銑鉄市場は好調で
