Hygiene and health: various modifiers， additives， additives and other chemical components of plastic pipes in copper pipes.
積み上げる時，合理的に積み上げ，優先的に置くべきである.
ポートディクソン溶接後，〜℃でアニールして，& ;quot；セルフスプリット& ;quot；圧力.
銅管溶接プロセス用鋼線綿洗浄鋼管の端部とつのポート.清掃界面に影響を与え，溶接効果が低下するため，サンドクロスやサンドペーパーを使用して清掃しないでください.
ゴールバーンWhen placing， and should not be mixed together. The copper surface may have electrolytes， so it will react， especially with other materials such as rubber， which has a large impact.
銅管のつの製造方法の中で，酸化法が も多い.金属銅が陽極によって酸化され陽極の銅イオンが管材料に付着すれば，銅管を生産することができるからである.これ方法も銅材料を生産する も般的な方法である.長い間使用されているだけでなく，酸化反応による銅管の生産という成熟した技術があります.この生産方法は中国の銅管の主要な生産方法である.
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
First of all， we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C， while the humidity should be normal. The room should be kept ventilated.
（黄銅は銅亜鉛合金である.亜鉛は沸点が低いため，℃しかないため，溶接中に蒸発しやすく，これは黄銅溶接における問題となっている.
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.
変動コスト通常は酸素アセチレンをガス源として用い，液化石油ガス溶接工具を用いて加熱する.溶接工具の溶接トーチは継手に面して，ポートディクソン321ステンレス鋼円鋼，ポートディクソンアルミニウム板，継手全体を連続的に加熱しなければならない.これにより，過度な局所加熱が回避される.
When stacking， it shall be stacked reasonably and placed first.
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.
Tangshan billets rose sharply last weekend， steel mills in some northern cities implemented production restriction， and some domestic economic data improved， which boosted manufacturers confidence. Today steel prices generally rose. However， with the approaching meeting and the rainfall in the south caused by the typhoon the construction progress of the downstream construction site is affected， which is not conducive to the continuous demand. The high spot price transaction today is weak， which is difficult to support the continuous rise of steel prices. It is expected that the building materials market will maintain a volatile trend tomorrow， and some businesses may reduce prices and take goods.

Re treat the water quality.
銅管の導電生産はこの方法の 新の方法である.導電性を有するナノ結晶銅材料の生産である.この原材料は非常に特殊であるため，ナノテクノロジーを利用して生産された銅材料であり，分離された銅イオンで銅管を生産することができる.この方法は非常に複雑で，高い技術と新しい設備が必要なので，海外の先進国だけがこの生産方法を使用することができます.
ポートディクソンThe material of the water separator is the same， the expansion coefficient is the same， and the connection with the water separator is not easy to leak. Scope of application: As the copper pipe is more expensive than the plastic pipe， the cost of the floor heating system is higher.
In August， the price of domestic medium and heavy plates fell sharply. As of August ， the price center of ordinary carbon boards in leading cities had dropped to ， down yuan/ton from the end of July. At the beginning of the month， affected by the macro bad news， and the recent poor performance of fundamentals the market mentality turned to pessimism， and some traders shipped at low prices. The market inventory rose， the inventory pressure was high， the stock shortage phenomenon disappeared， and the market transaction atmosphere was cold， the demand performance continued to decline， and the spot price fell under pressure.
Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.
