Our air conditioner connecting pipes are precision-engineered for split ACs, VRFs, and heat pump systems. Pre-charged with nitrogen to prevent contamination, these copper refrigerant pipes ensure optimal HVAC performance.
Key Features:
Bendable & Flared Ends for easy installation
Corrosion-Resistant with phosphoric acid cleaning
Multiple Size Options (1/4" to 1-1/8")
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 of 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 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. They are completely wrapped in copper-aluminum joints, and the seal cannot turn.
