シームレス銅管
Copper tube has good conductivity and is the main material of conductive accessories and heat dissipation accessories of electronic products. Copper tubes have strong corrosion resistance, are not easy to oxidize and react with some liquid substances. It is the first choice for modern contractors to install water pipes, heating and cooling pipes of all residential commercial houses.
Copper tubes are also called copper tubes. The utility model relates to a non-ferrous metal pipe, which is a pressed and drawn seamless pipe. Copper pipe has the characteristics of good conductivity and thermal conductivity. It is the main material of conductive fittings and heat dissipation fittings for electronic products, and has become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial buildings. Copper tubes have strong corrosion resistance, are not easy to be oxidized and react with some liquid substances, so they are easy to be bent and formed.
About 75% of copper tubes in China are used in the refrigeration industry. Because of its excellent flexibility, thermal conductivity and corrosion resistance, copper pipes are widely used in the evaporator, condenser, connecting pipes, pipes and pipe fittings of air conditioners, refrigerators and freezers, among which air conditioners are the main downstream. In 2021, the output of air conditioners, household refrigerators and freezers will increase significantly. In the first half of the year, the output will be 15.85 million units, 44.35 million units and 15.85 million units, respectively, 21%, 19% そして 42%. The increase of refrigeration output will drive the demand for copper tubes for refrigeration.
In offshore engineering, copper alloy condenser tubes have excellent electrical conductivity, thermal conductivity, corrosion resistance and other properties., It has broad application prospects. At the press conference in June 2021, the National Development and Reform Commission said that 123 desalination projects have been completed in China, with a total capacity of 1.65 million tons/day. The Action Plan for the Development of Seawater Desalination and Utilization proposes that by 2025, the total scale of seawater desalination in China will reach more than 2.9 million tons/day, and the new scale of seawater desalination will reach more than 1.25 million tons/day, so there is a great demand for copper tubes of heat exchange condensers.

Phosphorus-Deoxidized copper tubes – C12200 – are extensively used in sugar refineries for condensers and evaporators. Deoxidized copper is the standard material for transferring heat from steam to water or air because of their excellent resistance to corrosion by fresh water and their high thermal conductivities.
Copper tubes are easy to install, 輸送が安価で、メンテナンスが少なく長寿命. それらは広範囲の液体と互換性があり、多種多様な環境条件に対して非常に耐性があるためです, 銅製のチューブは、長期間にわたって非常に費用対効果の高い長期的な性能を提供します. それらは地上と地下の両方で配管システムを形成します, 氷点下および高熱用途で. スプリンクラーシステム, 極低温植物, 空調および冷凍システム, 病院用酸素システム, ガスおよび蒸気加熱システムと排水/ベントシステムはすべて、パイプとして銅管を使用します. また、他の金属パイプよりも占有するスペースが少なくて済みます.
安全と品質を確保するために, すべての銅管は厳格なASTMに準拠する必要があります (米国材料試験協会) 銅純度に関する規格, 設計, 継手と液体/ガスの互換性. それらは一般に押出プロセスによって形成されます, 均一な肉厚と滑らかな表面を持つシームレスチューブを製造します. 棒の形をした中実の銅ビレットは、可鍛性になるまで加熱され、次に所望の形状に達するまでチューブの形をした一連のますます小さな型に押し込まれます. 押し出し後, 彼らはしばしばローラーやマンドレルを使って曲げられます, そして溶接によって端で互いに取り付けられています.
ほとんどの銅管にはねじ山の端があります, 男性1名、女性1名, そのため、互いに簡単に取り付けたり取り外したりできます. スレッドは非永続的ですが、それでも信頼性を提供します, 気密および水密シール. 時々チューブはろう付けによって接合されます, 非鉄フィラー材を用いた溶接技術. 銅管の利点は、可燃性と耐爆発性です. チューブ内で火災が発生した場合, パイプシステムにそれ以上移動することはありません. 銅管は、ソフトまたはハードテンパーのいずれかを持つことができます, これは金属の全体的な硬度です. これは、製造後の熱処理によって達成されます.
