Insulated Copper Aluminium Connecting Pipe
Welding point: no pores/cracks/burrs/burn through, unfused, no oxidized.
Air tightness: using high pressure package 4.0MPa pressure for 5 minutes, no leakage.
Pressure resistance: in the air tightness test, slow pressurization to 13MPa for 1 minute, without any crack.
Bending: Bend the sample into the bending center to pipe nominal diameter 2 times, no wrinkle and crack after 180 degree bending.
Tensile strength: tensile strength in 65-118MPa, the broken part is on aluminium pipe, and the distance from the welding place is more than 10mm.

Air conditioning copper tubes are an important component in the air conditioning system, playing multiple roles such as conducting and conducting heat, connecting major components, resisting corrosion, and possessing certain strength and plasticity. Their performance directly affects the operation effect and lifespan of the air conditioning system. Therefore, in the design and manufacturing of air conditioning systems, the selection and use of air conditioning copper tubes require great attention
