Technical standard of copper aluminum connecting pipe:
(1)Welding point: no pores,cracks,slag,burrs and burn,not fusion,no obvious oxide film,no plug hole without significantly reduced(Φ6.3hole is larger than 3.0mm);
(2)Air tightness: using a high pressure for 4.0MPa pressure for 5 minutes, no leakage;
(3)Pressure: after the air tightness check is qualified, slowly press the pressure to 13MPa,keep for 1 minute, without any cracks ;
(4)Bending: The sample is bent into a curved core diameter of 2 times than the nominal diameter of the pipe,after bending 180 degrees, the pipe does not produce wrinkles and cracks;
(5)Tensile strength: The tensile strength is at 65-118mpa, the pull part is on the side of the aluminum pipe, and the weld is above 10mm;
(6)KTG: Shrink good, sealed accessories have been melted, completely wrapped in copper aluminum joints, the seal can not turn.

8. RoHs approval
Fire Resistance Custom Make Air Conditioner Use PE Insulated Copper Tube
Advantage
1- Completely conformed to the newest EU envirmontal standards SVHC.
2- High thermal stability, which is suitable for higher processing temperature(>170ºC).
3-It has good mechanical property. Performance in all respects has almost kept same with pure resin.
4-It has good colurability, which can be configured to all kinds of colors.
Flame Test
Fire Resistance Custom Make Air Conditioner Use PE Insulated Copper Tube
Little white smoke come out during flame retardant process,no residue contents after buring. No smelly smoke which is conformed to environmental requirement,fit the request of RoHS and SVHC standard.
