ASTM B111 UNS C12200 Copper Tube

Copper Tube, Copper pipe and tube TP 2 tube C12200 TUBE, JIS H3300 C1220T TUBE

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.

ASTM B111 UNS C12200 Copper Tube

ASTM B111 UNS C12200 Copper Tube

Standard Specification for Seamless Copper Tube
This specification establishes the requirements for seamless round, rectangular, and square copper tube (UNS Nos. C10100, C10200, C10300, C10800, C12000, and C12200) suitable for general engineering applications. The material of manufacture shall be billets, cast bars, or tube. The tube shall be manufactured by hot- and cold-working processes, shall be cold drawn to the finished size and wall thickness, and shall be supplied in cold-drawn or annealed temper condition. The material shall conform to the chemical composition requirements prescribed for copper, phosphorus, and arsenic, as determined by chemical analysis, and to the mechanical property requirements including tensile strength, yield strength, Rockwell hardness, and straightening. Requirements for grain size, electrical mass resistivity, and dimensions are specified. The following test methods are detailed: grain size, electrical resistivity, tensile and yield strength, and hardness tests, expansion test for round table, microscopical examination, test for hydrogen embrittlement, and nondestructive tests such as electromagnetic (eddy-current), hydrostatic, and pneumatic pressure tests.
