First of all， we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C， they must be isolated.
リンバンCorrosive agents such as calcium bicarbonate， inositol hexaphosphate， silicon phosphate crystal， etc. are added to the water to regulate the PH value of the water and the corrosion symptoms.
別の集散地である江陰市場では，現在流通段階の全体在庫は約万トンで，通常のレベルをやや下回っている.今週初め江陰価格と北方価格の価格差もやや低い流通在庫に対応している.しかし，リンバン304ステンレスパイプ，南鋼，恒潤，ダダなどの全体的な生産状況は比較的正常で，中程度の正常水準に属しており， 近の楽従市場の現物価格は北方と大きな差がある.
ティーズニートAmong the three production methods of copper tube， the oxidation method is the most. Because as long as the metal copper is oxidized by the anode and the copper ion of the anode is attached to the tube material， the copper tube can be produced. Thisthod is also the most common method to produce copper materials. It has not only been used for a long time， but also has a mature technology， which is to produce copper tubes through oxidation reaction. This production method is the main production method of copper tubes in China.
鉄鉱石先物の主力はポイント高のポイントだった.この日の終値は前日終値と変わらず，****，****，出来高，持倉量だった.日内取引g出来高は前取引日より万減少し，持倉量は前取引日より万減少した.日連続で下方修正された後，今日の皿の底部は反発したが，その後再びコールバックし，終値は横ばいだった.
Save materials and total cost， stability and performance， and can save maintenance.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
{} The excellent performance of copper pipe The welded copper pipe has the characteristics of firmness and corrosion resistance which makes it a suitable choice for modern contractors to install the water pipe， heating pipe and refrigeration pipe in all residential commercial houses.
暖房シーズンの到来に伴い，紫銅排の原料支持は弱い.暖房シーズンと環境保護の生産制限の影響で，リンバン60 SI 2 MN合金丸鋼，部の地域の製鉄所では暖房シーズンの高炉生産制限措置が実施され始め，鉄鉱石需要が弱まっている.また，リンバン12 CR 1 MOV合金板，今日は唐山で産出制限政策を発表しました.月日時から月日時まで，本通知に規定された生産制限措置を実行する.
生産部溶接時には，吹管は鉛管に垂直であり，火炎は連続的に移動して，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.

臨沂管工場の出荷価格は，現金宝成（* mm，以下同じ）元，金正陽元，宝達元，美新元，太宗元がそれぞれ元，元下がった.
First of all， we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C，製鉄所では，製鉄所のロック価格が下落しており，受注状況は芳しくない.この製鉄所の生産能力利用率は低いが，市場は依然として供給過剰である.製鉄所の在庫と現物在庫が上昇しているそのため，市場価格は大幅に下落した.その後，先物市場は反発し，現物価格も上昇した.瞬にして大量の取引が発生した.しかし，ブラック先物の下落に伴い，市場の取引量は大幅に縮小した.また，在庫圧力が大きく，貿易商は低価格で出荷し，現物価格は下落に耐えた.中厚板の落下防止能力が高いため，落下幅と速度はねじ山より小さい.
Many people do not fully understand the storage method of copper tubes in the process of use and production methods.
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.
リンバン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， but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising， so the market price has fallen sharply. Subsequently， 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.
