High-Purity C12200 Copper Round Pipe 1/8"-6", ASTM B846, Chemical Processing

C12200 phosphorus-deoxidized copper round pipes are designed for aggressive chemical and industrial environments. Compliant with ​ASTM B846, these seamless pipes range from ​1/8" (3.18mm) to 6" (152.4mm) in diameter, offering exceptional resistance to corrosion, oxidation, and high-temperature degradation. Ideal for chemical processing, petrochemical plants, and marine applications, C12200 copper ensures reliability in handling acids, alkalis, and volatile organic compounds (VOCs) while maintaining ultra-high purity for critical fluid transfer.
