銅自体の特性上，環境湿度の高い場所では錆びや腐食しやすいしつど私たちがよく使うと，問題はさらに小さくなりますが，長時間放置すると銅が破損します.銅の表面をどのように処理するか分からない人が多いのではないでしょうか.これでスタッフに回答させていただきます.
[] 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， because it will affect the clean interface and result in poor welding effect.
札幌何かのひとつ銅管の腐食般的な波形は単の銅管である.双曲線は，つの異なる円弧が同じサーフェス上で重なることを意味します.つまり，異なる中心からつの半径で円弧を描画します.赤銅管は図面に基づいて設計された双曲線モジュールである.赤銅管は軽量で剛性があり，強度が高い.加工された赤銅管の形状は異なり，円弧や球体などさまざまな幾何形状に加工することができます.それは美しく，優雅で，多彩です.ジャン&# ;銅管の加工と成形のつの主要な方法についてお話しします：熱加工と成形方法は銅管をほぼ双曲線形状に転圧し，それから加熱して，それを事前に準備した金型の上に置いて，それからハンマーでゆっくりたたいて，溶接，折り畳み，研磨と研磨を行います.全体のプロセスは，銅管の表面品質を確保するために非常に注意する必要があります.この成形方法は，モデルが小さく，アークの変化が大きい部品に適しています.モデルサイズが比較的大きく複雑な場合は，それを小分けして成形し，ブロックに接合することが考えられます.このような銅管では，コストが高く，生産サイクルが長い.ロール曲げ成形方法この方法はロール曲げ機をいくつか修正し，その中のつの軸を凹形に変更し，もうつの軸を凸形に変更する.この方法は球体のような規則的な銅管を形成することができ，加工範囲は小さいが，ラジアンの小さい銅管には大きな利点がある.双曲面銅管の設計で注意すべき問題は何ですか.エアコンの銅管のデザインが非常に重要であることはよく知られている.双曲面銅管の美しい外形，精緻な工芸とファッション個性を実現するには，まず，設計が非常に重要である.いくつかの小さな銅管継手パニーズは設計面で成熟しておらず，分な設計経験がないため，設計において常に問題に直面しています.双曲線銅管は，私たちが設計に注意すべき詳細を準備することで知られています.彫刻された銅管は装飾性が強く，双曲形銅管の生産と加工技術は相対的に複雑である.銅管製品は，美観性が強い.設計要求に応じて，銅管を彫刻するには異なる形状を成形する必要があるため，アルミニウム単板を彫刻する生産技術は比較的複雑である.

In Jiangyin market， another distribution center， the overall inventory of the current circulation link is about tons， slightly lower than the normal level. At the beginning of this week， the price gap between Jiangyin prices and those in the north has also been able to correspond to the slightly lower circulation inventory. However， from the perspective of the policy port of the steel plant， the overall production situation of Nangang， Hengrun， Dada， etc. is relatively normal， and the amount of resources in the later period remains stable. The overall inventory of Lecong market remains at about to tons， which is a medium normal level，札幌310 sステンレスシームレス管， and the recent spot price of Lecong market has a large gap with that of the north.
It has excellent conductivity， thermal conductivity， ductility and corrosion resistance.
Safe and reliable: copper pipe combines the advantages of metal pipe and non-metal pipe. It is harder than plastic pipes and has the high strength of ordinary metals (the strength of cold drawn copper pipes is equivalent to that of steel pipes with the same waess); It is also easier to bend than ordinary metals， has good toughness and high ductility， and has excellent anti vibration，札幌Q 345 D合金円鋼， anti impact and anti frost expansion properties.
Copper pipe has the characteristics of firmness and corrosion resistance， and is the choice for the installation of water pipe， heating pipe and refrigeration pipe.

Generally， 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.

Four in one formula and process conditions Preparation of solution Take formula as an example: mix the calculated amount of water for zinc oxide into a paste， slowly add it into the calculated amount of phosphoric acid under stirring until it is completely dissolved， then add zinc nitrate and tartaric acid， add sodium alkosulfonate and OP emulsion， and stir to make it completely dissolved. Then add chromium dihydrogen phosphate dissolved in dilute phosphoric acid， and add titanium sulfate. After all materials are added， dilute them to the total volume， stir them to make the solution even， cool them to room temperature， put a large amount of iron filings in the solution， and soak them for - days to make them contain enough ferrous ions. When the content of ferrous ion reaches above g/L， adjust the free acidity and total acidity of the solution to the specified value， and then the solution can be used at elevated temperature. When the ferrous ion reaches the above value， the phosphating speed is fast， the solution is stable， and the phosphating film is fine and dense. During operation， attention shall be paid to controlling the temperature. If the temperature is higher than ℃ the degreasing technology of degreased copper pipe. How to make degreased copper pipe? The process flow of degreased copper tube? What are the characteristics of degreased copper tubes? Use of degreased copper tube? There are too many questions. Lets solve them at once. Everyone knows the copper tube. Nitrate reacts easily. The heater should be installed on the two walls of the tank， not on the bottom of the tank， to prevent local overheating. Stainless steel pipe or iron pipe should be used for heater， and lead pipe or copper pipe should not be used to avoid contamination of solution by impurities. What is degreased copper pipipe? "The advantages of degreased copper pipes comprehensive treatment of grease， rust removal， phosphating and passivation are described. This comprehensive treatment process can simplify the process， reduce the work area， save equipment costs， shorten working hours improve labor productivity and reduce costs. This method can only be used in the occasions where the requirements for coating quality are not high.However， in actual production， due to the amount of oil contamination， the consumption rate of each component in the solution is different， so attention should be paid to adjustment and control to maintain its due role. What is the degreasing copper tube? "I have roughly known the degreasing methods of degreasing copper tubes: solvent degreasing， alkali degreasing， ultrasonic degreasing， high pressure hot water degreasing， electrolytic degreasing， etc. Solvent degreasing: use degreasing solvent to dissolve the oil on the surface of red copper pipe， collect it together into a container， collect and reuse the volatile solvent， and separate the pollutants from the circulation system. This method was used in the early stage， which has problems such as low cleaning efficiency difficult maintenance， many kinds of surfactants have been developed. The lipophilic group of surfactants can help to dissolve oil in water to realize degreasing. Alkali degreasing: Alkali degreasing is a complex chemical physical process. In addition to saponification reaction and environmental pollution. In recent years， there are sometimes emulsion reaction and adsorption reaction. Typical saponification reaction formula is as follows: RCOOH+NaOHRCOONa+HO At present， and the solution temperature is ℃. Ultrasonic degreasing: ultrasonic degreasing is to degrease the upper and lower surfaces of red copper pipes by using ultrasonic to generate high-speed vibration， whichtly used for monomer and irregular shaped components. High pressure hot water degreasing: without degreasing agent， heat the deionized water to ℃， and spray it directly to the surface of red copper pipe for cleaning under the pressure of about bar. Electrolytic degreasing: electrolytic degreasing， using the red copper tube as the cathode to generate H， which can improve the degreasing effect. Therefore， the problem that alkali spraying and brushing cannot fully contact the micro concave part of the surface is solved. Generally the cleaning effect of alkali degreaser spraying or high-pressure hot water degreasing plus brushing can meet the requirements of most users. If there are special requirements， multiple methods can be used together. According to practical experience， the degreasing effect of various degreasing methods (one side of the copper tube) is as follows: alkali degreaser spray plus brushing: mg/m alkali degreaser brushing plus electrolytic degreasing: mg/m ultrasonic wave: mg/m high-pressure hot water degreasing: 札幌After the pipe is cleaned， the welding flux and flux shall be immediately applied to the interface and the bayonet clearance. Sufficient flux shall be thinly coated on the mating surface and assembled immediately， so that dust and dirt will not pollute the capillary gap. 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. しかし，短期的にはこの状況を変えることは難しい.短期的には国内の帯鋼価格が主に上昇する見通しだ.利益を追求するため，唐山鋼鉄集団有限公司は現在熱コイルの供給を増やしているという.将来的にはより多くの製鉄所が利益を追求したり，下落のために隠れた危険性を埋めたりする傾向があることを排除しない.明日については，価格は依然として幅の狭い揺れの運行構造を維持する可能性がある.
