* Values indicated for pressure in the table above are computed for soft tubes with safety factor N=5. Values indicated for allowable pressure relate only to tubes, not to their joints.

 

Weight and maximum allowable working pressure of fluids are computed using the following equations for each copper tube size:

For weight:

For pressure:

Q = (D - S) x S x π x γ, gr/m

P = 200 Rm S / DN, bara

where: where:
D - outer diameter, mm 200 - conversion constant
S - wall thickness, mm Rm - tensile strength, N/mm²
γ - specific weight of copper, 8.94 kg/dm³ S - wall thickness, mm
π - 3,14 D - outer diameter, mm
  N - safety factor (5)
