軟銅管の生産方法は硬銅管と基本的に同じであり，すなわち硬銅管と比較してアニールプロセスが増加した.銅管のアニールは，銅管中の元素の配列を変更するために高温炉で焼成することを意味する.しかし，アニールすると銅管が柔らかくなり，曲げやすくなります.このようにして生産された銅管を軟銅管と呼ぶ.
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.

今週の銑鉄市場の価格は-元上昇し，取引は公平だった.コークス価格の上昇に伴い，山西省，河南省，遼寧省，山東省などの地域の球状インク鋳鉄のコストが増加した.また，下流の需要が徐々に放出されるにつれて，ムドン310 sステンレス鋼板，製鉄所の在庫量は大きくなく，製鉄所は続々と値上げされている.山東，ムドンステンレスコイル，江蘇，河北，山西の鋳鉄工場は少なく，在庫は依然として低い.コークス価格の上昇とコストの増加に伴い，次に普通の金属の中にあります.しかし銅は銀よりずっと安いので，それはすでに& ;quot；主役& ;quot；電気業界のリーダー.
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.
At the opening this morning， the market price of Zhengzhou copper bar was basically stable. According to the monitoring data of the Lange cloud business platform， the current market price of * mm Linyi copper bar was yuan (ton price， the same below)， the * mm copper bar was yuan， and the * mm copper bar Henan copper bar was yuan.
Remove the flame. If the filler metal does not melt， continue to heat the joint and try again. The melted filler metal is sucked into the casing port according to the capillary effect until a complete filler metal ring appears on the casing port. Remove the flame Pay special attention not to let the flame directly contact the filler metal. It should be the heat at the joint that melts the filler metal. In order to clean the copper pipe， the welding flux must have a degree of corrosivity， and shall be cleaned after brazing. The so-called "self-cleaning" fluxes are generally not recommended because of their corrosivity.
Corrosion caused by water with high chloride ion content.
これらの要素を考慮して，月以来，ますます多くの鉄鋼工場が生産を停止し，呉州の生産量も制限されている.西安と唐山の暖房シーズンが早まった.また，生産制限を正式に実施する.quot；+&；quot；鉄鋼企業の月日以降の都市暖房シーズンは，将来的に鉄鉱石需要がさらに悪化する可能性がある.製鉄所の鉄鉱石在庫は相対的に高く，さらに在庫を補充する意欲は強くない.供給の面では，第半期は通常，輸入鉱石の出荷のピークである.環境保護のため，国内鉱山の生産量は減少したが，***の数は相対的に限られている.全体的に言えば，短期鉄鉱石市場は上昇動力に乏しい可能性がある.

Red copper inventory in key areas has risen continuously， but the total pressure is not big. From the current overall inventory situation of the main distribution centers Wuan， the inventory level remains relatively moderate， and the pressure on the market is relatively small. In Wuan market， according to the data， as of May ， the total inventory of medium and thick plates in Wuan was close to tons， increasing by tons on a weekly basis. In late April， it reached tons lower in the year， and rose for three consecutive weeks. In terms of the ovquantity， it should be said to maintain a relatively moderate level.

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， the drop amplitude and rate are less than those of threads.
検査環境On October ， according to the Economic and Information Commission oong Province， at the end of September ， Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel， and all the de capacity equipment had been shut down and withdrawn. On October ， the Development and Reform Commission of Handan City released the Plan for Handan City to Eliminate Excess Iron and Steel Capacity. Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.

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，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.
ムドンThe market price of Zhengzhou copper bars is basically stable， and the shipment is not good. In terms of tube blank: today， Shandong Luli tube blank slightly reduced by yuan， and the current mainstream ex factory price is - yuan. In terms of pipe plant: Linyi Pipe Plant locked the price for a week. With a stable market mentality， the factory price of hot rolled seamless pipes is now between - yuan. On the market side: with the arrival of the off-season， traders generally ship goods at a high price. Replenishment is mainly to maintain the existing inventory， and there is no large replenishment plan. The demand is sluggish， and the market price of Zhengzhou copper bar is expected to be stable and declining.
