Advantages: good quality， fine structure， high density， large bending deformation， suitable for frequent cold and heat exchange， large temperature difference in working environment and large size copper tube can be produced.
銅自体の特性上，チュメニ中空アルミニウム管，長時間放置すると銅が破損します.銅の表面をどのように処理するか分からない人が多いのではないでしょうか.これでスタッフに回答させていただきます.
チュメニ水に重炭酸カルシウム問題はさらに小さくなりますが環境湿度の高い場所では錆びや腐食しやすいしつど私たちがよく使うと，ヘキサリン酸イノシトール，リン酸珪素結晶などの腐食剤を添加し，水のPH値と腐食症状を調節する.
However， it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits， Tangshan Iron and Steel Group Co.， Ltd. is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits， or to lay hidden dangers for the decline. As far as tomorrow is concerned， the price may still maintain a narrow range of shock operation pattern.
アラウコ月，国内の中厚板価格は大幅に下落した.月日現在，主要都市の普通炭素板価格センターはに下落し，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，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，在庫圧力が高く，在庫不足現象がなくなり，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.
In the first ten days of May，チュメニ15 CRMO合金板， the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak. Due to the weak market shock， the overall order intake of the spot steel market was relatively weak. The total quantity of orders received in the first ten days of May is only about tons， while at the end of April， the total quantity of post settlement agreements of main steel plants can exceed tons.
カートリッジの上部にチューブを挿入し，eパイプ上のスリーブを継手に均に塗布し，パイプがソケット底部に挿入されていることを確認し，余分なフラックスを拭き取り，継手が組み立てられて加熱可能である.
This week (-， the market price of red copper bar rose， and the transaction was not ideal. On the bidding day of Shagang last weekend， the price was stable to support the market， and the rising of billets at the weekend drove the market up in a wave， and the price of variety wire rods also rose by yuan at the weekend. However， it was reported that the deal was very poor， which led to the price being stable for the next two days. Until Wednesday， due to the negative outlook on the future market and the reduction of steel billets in the afternoon spiral diving， the market lowered the price. Market price changes， Xinji rose yuan on the rd; For the future market， the off-season is coming， the demand is weakening， and the market wait-and-see mood is getting stronger. But when winter comes， the environmental protection inspection is becoming more and more strict， which supports the market. It is expected that the price ofety wire rod will be adjusted in a weak way in the short term.

百科の知識So far as the storage method of copper materials is concerned， we should properly keep the copper products we buy， extend the service life of copper and ensure its performance to avoid unnecessary losses.
In consideration of the above factors， more and more steel plants have stopped production since October， and the production limit in Wuan and Tangshan heating seasons has been advanced. In addition， the formal implementation of production limit in "+" urban heating seasons after November by steel enterprises，チュメニブロンズ管， the demand for iron ore in the future is likely to further deteriorate. The iron ore inventory of the steel plant is relatively high， and the willingness to further replenish the inventory is not strong. In terms of supply， the fourth quarter is generally the peak period for the shipment of imported ores. Although the production of domestic mines has been reduced due to environmental protection， the quantity of * * * is relatively limited. In general， the short-term iron ore market may lack upward momentum.
唐山鋼片は先週末に大幅に上昇し，部の北方都市の製鉄所では生産制限が実施され，部の国内経済データが改善され，メーカーの自信を奮い立たせた.自信今日，鋼材の価格は普遍的に上昇した.しかし，会議の接近や台風による南方の降雨に伴い，下流の工事現場の工事進度が影響を受け持続的な需要に不利である.今日の高現物価格の取引は軟調で，部の業者は値下げして商品を受け取る可能性がある.
The simplest way is to use copper cleaner. Brass， red copper， bronze， etc. can be used. Oil stains， fingerprints， oxide layers， etc. on the surface can be cleaned with copper cleaner first.
安全衛生その後，メキシコの科学者は銅がつあることを発見した. 近，英国の研究者は，銅に強い殺菌作用があることを発見した.近い将来，銅は人類の健康改善に大きく貢献すると信じている.銅板T はその紫色から名付けられた.それは必ずしも純粋な銅ではなく，銅合金にも含まれています.中国会社の加工材料r板は成分によって種類に分けることができる：普通の銅板（T ，T ，T ，T，無酸素銅板（TU ，TU と高純度，真空無酸素銅），脱酸素銅板（TUP，TUMn）と少量の合金元素を添加する特殊な銅板（砒素銅，テルル銅，銀銅）.銅板の導電性と熱伝導性は銀に次ぐものであり，電気伝導と熱伝導デバイスの製造に広く用いられている.赤銅帯は大気，海水，いくつかの非酸化酸，アルカリ，塩溶液及び各種有機酸（aic酸，クエン酸）の中で優れた耐食性を有し，化学工業に用いられる.また，赤銅板は優れた溶接性を有し，冷間加工と熱可塑性加工により各種の半製品と製品を製造することができる.年代，銅板の生産額は他の銅合金を上回った.
堆積した銅管については，できるだけ外装を開けないようにしてください.
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.
チュメニ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.
以上のように，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.
