The blowpipe shall be perpendicular to the lead pipe during welding， and the flame shall be moved continuously to prevent local overheating and the flux from carbonizing before filler metal is added.
銅管の卓越した性能を持つ銅管は，現代の請負業者がすべての住宅商業住宅に水道管，暖房冷却管を設置するための適切な選択となるような和の特性を持っている.
ニボン・テバルThe evaporated zinc is immediately turned into zinc in the air， forming white smoke， which brings great difficulties to the operation and affects the health of welders. Therefore，ニボン・テバルブロンズ管， in the places where decorative brass pipes are welded ventilation and other protective measures should be strengthened. The poor weldability of brass will cause problems such as pores， zinc evaporation and so on.
The application of copper tube The copper tube is generally used in the heat exchange equipment cracks， 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.
サランコラ銅板，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.
It is said that due to the optimistic future and tight resources， some iron plants do not take orders temporarily. The steel mills in Liaoning have increased their enthusiasm for purchasing steel. The iron mills have delivered well， and the price of raw materials has risen， so the iron price has risen. The iron mills have a high enthusiasm for producing steel， so there is not much cast iron resources， and the price has risen. A few steel mills in Tangshan began to purchase a small amount of steel for smelting，ニボン・テバル銅アルミニウム複合列， and most steel mills are still on the lookout for inquiry. Under the background of increasing cost and gradual release of demand the pig iron market is performing well and is expected to continue to operate strongly in the short term.
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，ニボン・テバル2205ステンレス鋼板，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.
ビレットについて：時分，昌黎の部のビレットは本減少し，現在の炭素側ビレットは交付され，税込み元である.中国共産党第回全国代表大会後，市場は環境生産制限の不確実性に疑問を持ち，より明確な方向を待っている.そのため，この段階では，先物も現金も，方的な市場も，原稿発行時まで，天津優溶接生産ライン：製鉄所報告：栄成#元/トン， B 元/トン，江#-#~天津元/トン，新集オーソン#から貨物価格元/トン，B鋼から貨物価格元/トン，済源＃元／トン，B鋼元／トン，富倫#元/トン威鋼＃元／トン，B鋼元／トン.
And do a good job of data sorting.
In addition， so copper pipes need to be selected for many times in other places.

The conductive production of copper tube is the latest method for this method. It is the production of nanocrystalline copper materials with conductivity. Because this raw material is very special， it is a copper material produced by using nanotechnology， and copper ions can be separated by conductivity， so that copper tubes can be produced with the separated copper ions. This method is very complex， requires high technology and new equipment， so only advanced foreign countries can use this production method.
赤銅在庫は持続的な低下傾向に終止符を打つ可能性がある.鉄鋼企業の生産制限力の増大と需要圧力の増大に伴い，鉄鉱石港湾在庫の継続的な低下は終了する可能性がある.また，**の 新統計によると，製鉄所が鉄鉱石を輸入できる日数は日で，国慶節前より日減少し，過去 高となった.製鉄所によると，現在の鉄鉱石在庫は生産要求をほぼ満たしている.将来の減産と制限を考慮して，製鉄所は在庫を補充したくない.
検査方法On the other hand， in the steel plant， the lock price of the steel plant has been falling all the time， and the order receiving is poor. The capacity utilization rate of the steel plant is low， the futures market rebounded in a wave， and the spot price also increased with the increase. There was an instant of large volume of transactions. However， with the decline of black futures， the market transaction volume shrank significantly. In addition， the inventory pressure was high， traders shipped at low prices， and the spot price fell under pressure. Due to the strong drop resistance of medium and thick plates， the drop amplitude and rate are less than those of threads.
For the deposited copper tubes， do not open the outer packaging as much as possible.
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，鉄鋼価格の持続的な上昇を支えることは難しい.明日の建材市場は揺れを維持する見込みで，部の業者は値下げして商品を受け取る可能性がある.
ニボン・テバルThe main force of iron ore futures closed at in The closing price of the day today was the same as that of the previous trading day， including * * * * ， * * * ， settlement price ， trading volume ， and position volume . The intraday tradg volume decreased by compared with the previous trading day， and the position volume decreased by compared with the previous trading day. After six consecutive days of downward adjustment， there was a rebound at the bottom of the session today， but it was corrected again later， and the closing was flat.
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 stock shortage phenomenon disappeared， and the market transaction atmosphere was cold， the demand performance continued to decline， and the spot price fell under pressure.
