Material Properties

The pressure ratings in the table are derived from the following yield strengths (SS) for the base material:

  • Annealed Copper Tube: Yield Strength S=5100 psiS = 5100 \text{ psi} (35 MPa)(35 \text{ MPa})
  • Drawn Copper Tube: Yield Strength S=10000 psiS = 10000 \text{ psi} (69 MPa)(69 \text{ MPa})

Unit Conversions

Key pressure and dimensional conversions for reference:

  • 1 in=25.4 mm1 \text{ in} = 25.4 \text{ mm}
  • 1 MPa=1 N/mm2=10 bar=145.0 psi1 \text{ MPa} = 1 \text{ N/mm}^2 = 10 \text{ bar} = 145.0 \text{ psi}
  • 1 psi=6.895 kPa1 \text{ psi} = 6.895 \text{ kPa}

Relevant Standards

  • ASTM B88: Seamless Copper Water Tubes (covers Types K, L, M)
  • BS 2871: Copper Tubes (covers specifications like Table X, Y, Z)
