Brand Name: RETEKOOL
Model Number: 1/4''*0.8mm
Place of Origin: Zhejiang, China (Mainland)
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.
PE insulation is foamed by polyethylene water bridge,the middle layer is foamed by electronic bridge,
the other layer is made of polyethylene anti-aging and anti-untraviolet ray composite memberane,
which have high temperature resistant of 120℃.
Thermal insulated heat preservation tube material and characteristics
JIS A9511:PE-C-P2 standard,use for:
1. Water,liquid,powder,granule transmission
2. Electrical wire protection tubing
3. Drain hose for construction,etc.
4. Especially for air conditioner drainage use(Heat preservation drain hose for air conditioners,
Drain hose for central air conditioning system).
5. Size range accept custom size

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(>170℃).
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.
Production Flow:
Main Professional Exhibition :
We attend many many professional Fairs , such as Canton Fair , CRH , ARH (USA),CHILLVENTA(GREMANY) , MCE(ITALY) , FEBRAVA(BRAZIL)
Our product advantages
1.A long life: the outer surface of copper-aluminum connecting pipe with a cross-linked polyethylene (hot pipe) so antiseptic treatment to ensure the separation of water and moist air on the corrosion of aluminum tubes, life is more than 20 years.
2. Low cost anti-oxidation: copper-aluminum connecting pipe ends and the valve does not exist Jiechu oxidation corrosion and so easy to produce quality risk, copper and aluminum pipe to connect both ends of the brass, to avoid the occurrence of this problem and achieve a lower cost purpose
3. High cleanliness: as between copper and aluminum pipe without welding, but by cold access connection, to avoid all the high-temperature welding caused by the surface oxide production, so do not need any treatment can achieve cooling pipe The cleaning requirements.
4. Good insulation properties: air conditioning is needed to connect pipe insulation, and to improve the air conditioner's energy efficiency, should further improve the connection pipe insulation performance.
5. Safety performance: copper-aluminum connecting pipe bursting pressure and allow the copper connecting pipe burst pressure to allow the same design pressure are 13.0Mpa
6.Bending excellent performance, easy to install, move machine: aluminum than brass soft, copper-aluminum connecting pipe copper tube design is 1.5 times the wall thickness
