欠点：組織が緩く，高圧に耐えられるため，このパイプは小型エアコン銅棒の生産にしか使用されていない.
倉庫に他の製品，特に他の酸性材料とアルカリ性材料を保管しすぎないで， heat conduction and corrosion resistance are excellent， and the W shape trend of air conditioning copper pipe is depressed due to the high copper content. Good machinability， fusion welding and brazing are very good. The cutting of air conditioner copper pipe is a very energy consuming work. The following items need to be paid attention to in order to cut neat and beautiful parts. Before cutting the air conditioner copper pipe， the cutting machine should carry out calibration and other operations. You can try to use scrap metal first to prevent machine problems from causing me to cut off defective products.
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.
ラティ溶接時には，吹管は鉛管に垂直であり火炎は連続的に移動して， the overall order receiving quantity of Tianjin Hebei Henan Plate Plant was not ideal. According to the monitoring data局所的な過熱と溶接剤が充填金属を添加する前に炭化しないようにしなければならない.
In the first ten days of May， 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， the total quantity of post settlement agreements of main steel plants can exceed tons.
antages: low production cost and high production efficiency.
For small diameter pipes， when using filler metal， the length of filler metal is allowed to be equal to the diameter of the pipe， which is enough to fill the weld crater. One of the five major application fields of red coppr plate T， red copper bar and red copper tube: copper is the most widely used and used in the electrical and electronic industries， accounting for more than half of the total consumption. Used for various cables and wires， motors and transformers， switches and printed circuit boards; In the manufacture of machinery and transport vehicles， it is used to manufacture industrial valves and accessories， instruments sliding bearings， molds， heat exchangers， pumps， etc.
コイル表面の汚染による変色を回避し，潤滑油や洗浄剤などの補助材料の成分を制御する.仕入先Yes粘度，引火点，酸価，蒸留範囲などの技術性能指標，及び銅管有害元素の第者検査報告書を提供することを要求する.巻戻しの過程で，銅管表面の洗浄を強化し，銅管表面の潤滑油の残留を減少させる.
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.
品種がそろっている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，山東，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，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.
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， distillation pots，天津GCR 15合金丸鋼， brewing pots， etc.
銅管のつの製造方法概説銅管は銅材料のつの非常に重要な材料である.このような銅管の生産を完了する方法はたくさんある.銅管については，通常，以下のつの方法を用いて材料を製造する.このつの方法で生産された銅管は性能が非常に良いだけでなく，操作も非常に便利です.銅管にはつの生産方法がありますが，銅管のつの生産方法は何ですか.
The copper bar market declined steadily this week， with a decline of - yuan. Due to low pig iron inventory， some steel mills in Jiangxi have resumed purchasing recently， but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently， the steel market has been in shock and adjustment， and the merchants are unstable. Steel mills in Hebei Tianjin and other regions have stopped producing pig iron for steelmaking. Now， it is mainly expected to make inquiries. However， due to the lower price of raw materials， the price of iron mills has been lowered.
みんな見てください銅管床暖房の利点と適用範囲現在，床暖房は快適な暖房方式であるだけでなく，現代の生活の質の象徴でもある.地熱放熱器を使用する住宅，公共建築，スポーツ施設，工業施設などの場所が増えており，多くの場所で放熱器の主な材料として銅管が選択されている.
{} The copper pipe welding can be divided into soft welding and hard welding. The soft welding temperature is lower than ℃， and the hard welding temperature is higher than ℃. Hard welding is usually used for silver， gold， steel， copper and other metals. Its welding points are much stronger than soft welding，天津おうどうばん， and its shear strength is - times that of soft welding.
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.
天津In the morning trading today， the price of domestic copper bar fell. According to the monitoring data of Lange Steels cloud business platform， the average price of * mm hot rolled strip in key cities in China is ， down yuan from yesterday. Futures prices fluctuated， and the prices of spot market manufacturers eased slightly today. According to the feedback， the market was mainlysee yesterday， which caused the overall transaction blocked， and the mainstream manufacturers prices fell today.
First of all， we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C，天津ごうきん鋼， while the humidity should be normal. The room should be kept ventilated.
日中後期には，先物価格の上昇や武鋼の生産制限政策の増加などの朗報があったにもかかわらず，在庫レベルが高いため，貿易商は値上げの意思がなく，彼らの多くはすでに出荷されており，邯鄲の市場在庫は節後に高い水準に達した.長期的な低迷した需要表現は市場の供給過剰を招き
