Tangshan billets rose sharply last weekend， steel mills in some northern cities implemented production restriction， and some domestic economic data improved which boosted manufacturers confidence. Today， steel prices generally rose. However， with the approaching meeting and the rainfall in the south caused by the typhoon， the construction progress of the downstream construction site is affected， which is not conducive to the continuous demand. The high spot price transaction today is weak， which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow， and some businesses may reduce prices and take goods.
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.
香港銅管の腐食による損失を減らすために，銅管を定期的に検査し， 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.
ムマバトSome steel mills in Liaoning are interested in purchasing pig iron， but the local resources are tight， and the iron mills quotations are on the high side， resulting in a stalemate between supply and demand. The demand for cast iron and ductile iron in Jiangsu， Shandong， Shanxi， Hebei， Henan and other regions is sluggish， and the inventory pressure of iron mills is increasing. As the price of raw materials decreases， the quotation of iron mills continues to decline. At present， the demand and cost support are weak， and there is no positive boost. The short-term pig iron market is weak and difficult to change.antages：生産コストが低く，生産効率が高い.
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.
After the pipe is cleaned， the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately， so that dust and dirt will not pollute the capillary gap.
When placing，香港アルミニウム排冷凍庫， they should be stored separately according to the different components， so it will react， especially with other materials such as rubber， which has a large impact.
銅管とスリーブを加熱して挿入し，温度は銅管を加熱する時の温度より少し高い.
When stacking it shall be stacked reasonably and placed first.
信用保証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，香港ブロンズ管， 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.
重点分野の赤銅在庫は上昇を続けているが，全体的な圧力は大きくない.現在の主要配送センターの全体的な在庫状況を見ると，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，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.
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.
銅板，銅棒，銅管のつの主要な応用分野のうちつ：銅は製造用であり，国防工業における銃器部品である.万輪の銅を生産するごとに，-トンの銅が必要になる.
インストール条件antages: low production cost and high production efficiency.
Therefore， it is often used in some ah heat exchangers to Kazakhstan oxygen equipment.
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.
香港 も簡単な方法は銅洗浄剤を使用することです.黄銅，紫銅，青銅などを使用することができます.表面の油汚れ，指紋，酸化層などはまず銅洗浄剤で洗浄することができる.
If you want to avoid this kind of situation for a long time， you can choose passivation treatment. In this way not only is the copper surface serious， it can be cleaned under normal circumstances， but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment
