The pressure calculation have been made according to ASME B31.3 the tolerances are in accordance with ASTM A213 / A269.
The calculation have been made at -20°F to 100°F (-29 °C to 38°C).

Test certificates:
Flare testing.
Rockwell hardness surface <B90.
Crushing test.
Hydrostatic testing.


COPPER:

Annealed copper tubes:
ASTMB68/ASTMB75
ASTM B 88 (K / L type)

Copper tubes coated in black PVC:
ASTMB68/ASTMB75

Chemical composition (Table 1 ASTM B 68.
ASTM B 75 and ASTM B 88).
Copper UNS No. C12200
Minimum 99.9 % Copper
Phosphorus % 0015-0040

Calculations according to ASME B31.3 standard based on a minimum stress value of 30 Ksi copper at a temperature between -20°F to 100°F (-29°C to 38°C) according to the tolerances in diameter and wall thickness for each standard.
