Problem analysis

 R410a refrigerant system has relatively high pressure.

If material does not meet the pressure-proof standards,

then it may cause copper pipe explosion.

Consequence

 Intensity and material specification doesn’t meet factory

requirement and this could lead to explosion while using

the product which could even bring personal injury.

Standard procedure

 Installation material requirement

Material : phosphorous deoxidized copper, purple

copper pipe

Analysis result shows that chemical component should

meet the below condition (KSD 1651)

Cu ≥ 99.90% ; P : 0.015%~0.040%

Mechanical properties need to meet KSD 5301

Proper method

 Selecting copper pipe

C1220T-O(JIS) : Soft type

C1220T-1/2H(JIS) : Semi-hard type
