Copper Nickel Brass UNS C44300 has a copper content of not less than 70%.

ASTM B111/ASME SB111 UNS C44300 Admiralty Brass is ideal for heat exchanger tubes. Normally made to order to meet engineering requirements, you will find this alloy often times used in oil and gas applications that also require its non corrosive properties. C44300 and C68700 have good corrosion resistance. C44300 Admiralty Brass Seamless Tubes Tensile strength minimum in 310Mpa, Yield Strength minimum in 105Mpa.

Hydrostatic Test – Each tube shall stand, without showing evidence of leakage, an internal hydrostatic pressure sufficient to subject the material to a fiber stress of 7000 psi, determined by the following equation for thin hollow cylinders under tension. The tube need not be tested at a hudrostatic pressure of over 1000psi unless so specified.

  • P = 2St/(D-0.8t) where:

  • P = hydrostatic pressure, psig.

  • t = thickness of tube wall, in.

  • D = outside diameter of the tube. in., and

  • S = allowable stress of the material, psi.
