- Our Advantages
Main equipment for air conditioner copper and aluminum connecting pipeButt resistance welding machine:
1.Insulation tube
Fire retardant, thermal insulation, not easy to aging, at the same time as the outer layer of copper and alum tube rust prevention.
2.Copper tube
Material is pure copper, good ductility, good thermal conductivity.
3.Aluminum tube
The material is 1070 aluminum tube with good ductility and thermal conductivity.
4.Heat shrinkable tube
Material PE, more effecive protection of copper and aluminum tube, rust and corrosion prevention, strengthen the toughness of aluminum tube.
5.Brass nuts
A set of air conditioning connection pipe a total of 4 copper nuts, nut material for brass,thickened strong, easy to operate.
6.Dustproof plug
A set of air conditioning connection pipe a total of 4 dust plug, prevent dust into the copper aluminum tube
