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.
