Insulated Copper tube in pair coil for Split Air Conditioner
Insulated Copper tube
Copper Coil Insulated Copper Pipe for Air Conditioner
Insulated Copper Connecting Tube for Air Conditioner
In accordance with the market demand, we especially developed 30m length conecting tube (copper tube fixed with 2 layers embossed PE insulation sleeve tube), the connecting tube has identification marks for every 1 meter length, and can be easily cut to certain length as 3m, 5m, 6m, 10m, 15m, 20m, 30m according to the project needs, so, it is easy to use, high efficiency, less waste and widely used in air conditioning system for large-scale shopping malls and factories. | |||||||||||||||||||||||||||||||||||||||||||||||||
Technical standard of copper 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 joints, the seal can not turn.
