1/4"x3/8" Mini Split Line Set

Copper aluminum butt welding technology would save 60% material cost compares to the copper line set. Just 20% of people start using aluminum line set, because of leakage problems. we got patent reward butt-welding technology in China and Korea and get Samsung approval and apply for mini split installation.

butt welding

How to judge the CU-AL butt welding line set is qualified?

Anti-Peeling Ability (Pw=P/B)
Pressure Resistance
Bursting Pressure Mechanical Property
Alloy Grade
Air-tightness Performance

1. Raw material:1060 aluminum pipe

1060 alloy grade is 99.6% above aluminum elements. soft and flexible.

2. Mechanical properties of air conditioner pipe

Aluminum Pipe Tensile strength: > 70Mpa
Aluminum Pipe Elongation:> 30%

3. Pressure Resistance requirement

Aluminum tube testing Pressure 4.9Mpa, no any deformed and expand happen
Aluminum tube bursting Pressure 13.0Mpa

4.Air-tightness Performance

Filling with Ni gas (2.0 MPA), keep the pressure for at least 16 hours, to see the pressure gauge with decreasing or not. No leakage is accepted

5. Anit-Peeling Ability (Pw=P/B)

Cu-Al Infusion Material: Al4Cu9
P=N/M, B=Width (mm)
Pn=Anti-peeling qualifying
T=Aluminum tube wall thickness
M=Aluminum tube tensile strength
T1=Aluminum wall thick after break pull

Conclusion:Pw>Pn>MxT1/T

Refrigerant lines Suited

R22
R410
R32
R132

Warranty

AC linset insulation：(heat resistant 120 ° C) JIS JCDA 0009 ul94 HBF
Bursting pressure test:>4.0Mpa
7 years more product service life
100% replacement when leakage happen
