To sum up， due to the influence of factors such as the current spot market price is much higher than the expected winter storage price of merchants， the gradual emergence of supply and demand pressure， and the weakness of raw material support， among which the contraction of market demand has a greater impact. Therefore， the author believes that in the short term， the spot building materials do not have the possibility to rise significantly， and the price of building materials may mainly operate in shock but with the shrinking demand， the supply and demand pressure becomes prominent， However， considering the influence of winter storage and other factors， it is still possible for merchants to lower the spot price in November.
ジャン&# ;銅管材料の利点を詳しく述べた：銅管床暖房とは熱水を熱媒体として利用し，銅管加熱管の中で循環し，地面を通じて と対流伝熱の方式で床を加熱する加熱方法である.，銅管の放熱効果が速く，耐熱性が強い.高温給水の場合でも，地熱管の使用寿命は影響を受けない.銅管は金属管であり，o傷がつきにくい.そのため，漏れにくい.高温に耐え，高圧に耐え，通常のプラスチック管に比べて.銅管の床は暖かく， oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.
Nkanacion防湿紙で包んで防湿保護することができます.酸化をある程度防ぐこともできます.亀裂や深刻な腐食が見つかった場合は，隔離しなければなりません.
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 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， 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.
銅材料の貯蔵方法については，私たちが購入した銅製品を適切に保管し，銅の使用寿命を延長し，その性能を確保して，不要な損失を避けるべきです.
銅管の種類の生産方法の複合法もこの方法のハイテク生産方法である.不純物を含む銅材料です.これらの銅材料，銅合金，複合銅材料を電気化学反応により緒に置きナノ結晶銅材料を作製し，その後，この材料を精製し，銅管材料を作製した.
In addition， it is very strong， not easy to be corroded， so copper pipes need to be selected many times in other places.The color change on the outer surface of the copper tube is difficult to control due to environmental factors. To prevent moisture absorption on the surface and core of the annealed brass tube， a constant temperature and humidity packaging room can be built. Packaging in the packaging room can avoid the color change on the outer surface of the copper tube. However， it is not easy to control the situation that occurs in the processing process. The cost of ensuring constant temperature and humidity in the whole workshop is too high. The following measures are taken to control the process materials: In the season of high temperature and humidity， during the production and processing of copper tubes， the amount of oil coating on the surface of copper tubes can be increased to form an oil film on the surface of copper tubes， which can isolate water vapor and corrosive gases， and prevent the corrosion of the surface of copper tubes; The humidity in the air at night is high， and the outer surface of the copper pipe is prone to corrosion and discoloration at night. Closing the doors and windows of the workshop at night can make the situation worse; After the coil surface is cleaned in the rewinding process， the coating amount of passivation agent on the copper tube surface is increased. After blanking in the rewinding process， plastic bags shall be added to the whole support material to further reduce the contact between the copper pipe and the air and prevent the surface of the copper pipe.
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， etc.

In view of the current overall price difference， the local copper bar price continued to rise at a high level today， while the regions outside East China did not show an obvious follow-up trend and the local price still has the advantage of price difference with the Northeast and Central China regions. The local inventory pressure will be further reduced due to the small volume of local follow-up goods under the influence of production restriction， and the price support of copper bar is still strong. However， at present， domestic real estate control is still being tightened. The markets expectation of future demand is weakening，現在流通段階の全体在庫は約万トンで the market price of copper bars in Shenyang is stable and the shipment is poor.
別の集散地である江陰市場では，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，製鉄所政策港を見ると，南鋼，恒潤，ダダなどの全体的な生産状況は比較的正常で，後期の資源量は安定している.楽従市場全体の在庫は万-万トン前後を維持し，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.
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.
指標銅の表面を再び明るくしたい場合は，銅点溶液で研磨することができます.銅表面をより明るくするだけでなく，ヨンペン7075アルミニウム管，銅表面の鉄さびや酸化層を素早く除去し，銅自体の光沢を回復することができます.
{} 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.
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.
ヨンペン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.
The hard copper tube is not artificially treated after being drawn or extruded， 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.
