Properties of Copper pipe
ACR annealed (R220) copper; mechanical properties, dimensions,
tolerances and eccentricity in conformity with standard UNI EN
12735-1. Can be used with refrigerants R407C and R410A gases,
internal cleaning and dehumidifying with inert gas with max
overall residue 0.034 g/sq m and ends sealed as laid down by
ASTM B280.
Insulation
Double closed-cell physically cross-linked expanded polyethylene
insulating sheath with the following specifications:
• thermal conductivity at 40°C λ ≤ 0.040 W/m*K
• water vapour diffusion resistance
(anti-condensation) factor μ ≥ 15000
• reaction to fire class 1
• operating temperature -80°/+120°C
• CFC free
External protective film (LDPE) in extruded polyethylene,
white colour, with added flme retardant, adherent to
expanded foam in order to guarantee a high level of anticondensation,
high resistance to abrasion and tears.
