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， 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.
以上のように，現在の現物市場価格が商店の予想冬貯蔵価格よりはるかに高く，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，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，コタバル6063アルミニウム管，業者は月に現物価格を下げる可能性がある.
コタバルAnd do a good job of data sorting.
The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.
スペインの町In addition，コタバルほうけいアルミニウムかん， it is not easy to be corroded and can adapt to various environments. It can be used normally at low and high temperatures， extend the service life of copper and ensure its performance to avoid unnecessary losses.
Generally we should properly keep the copper products we buy， 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.
管片価格の調整と引き下げは，主に環境保護の生産制限と温度と天候への需要が弱いためである. 近では，端末の需要も気温の急降下で萎縮し，弱い揺れを引き起こしている.滄州の地元貿易商とのコミュニケーションによると，先週の様々な朗報により，過去週間の滄州熱膨張管の出荷量が増加し，閑散期にはさらに良くなり，部の規格の出荷量も改善された.しかし，中小型パイプライン市場の取引雰囲気は依然として冷淡で，コタバルブロンズ管，需要は徐々に鈍化している.以上のことから， 近の滄州シームレス鋼管市場の価格は安定して弱体化する見通しだ.
In addition， it is very strong， 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 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.
Advantages of red copper tube Durability: copper has stable chemical properties， integrating cold resistance， heat resistance， pressure resistance corrosion resistance and fire resistance， and can be used in different environments for a long time.
誠実と信用をもって経営する[] Welding process of copper pipe Clean the end and seven ports of steel pipe with steel wool. Do not use abrasive cloth or abrasive paper to clean，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，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.
Lets elaborate on the advantages of copper pipe materials: copper pipe floor heating refers to a heating method that uses hot water as the thermal medium， circulates in the copper pipe heating pipe， heats the floor， and heats the floor through the ground in the form of radiation and convection heat transfer. I. The copper tube has fast heat dissipation effect and strong heat resistance. Even under the condition of high temperature water supply， the service life of the floor heating tube will not be affected. Two. Copper pipe is a metal pipe，o it is not easy to scratch. Therefore， it is not easy to leak. Three. High temperature resistance， high pressure resistance， relative to any ordinary plastic pipe. Copper tube floor is warm and resistant to high temperature and pressure. Four. Long service life. Five.
銅管の特徴は，水道管，熱供給管，冷凍管を取り付けることの第選択である.
高品質Five of the five major application fields of copper plate， copper bar and copper tube: copper is used in medicine. In the s， Chinese medical inventors Liu Tongqing and Liu Tongle found that copper has extremely strong s， and successfully developed the corresponding "Cancer Suppressing "， which is successful in the near future.
When stacking， reasonable stacking and first in first out shall be achieved.
Extrusion method: This production method is to cast copper ingots after smelting， and extrude copper tubes by large extruder after secondary heating.
コタバル銅管の接続堅固性が強い：銅管と銅管部品の接続が堅固である.
When welding， just add enough filler metal to fill the capillary gap. Too much filler metal will only form a ball at the bottom of the joint or run into the pipe.
Save materials and total cost， stability and performance， and can save maintenance.
