What is the connection between the air conditioning tubes?
Key points for connection of air conditioning copper tube brazing operation of air conditioning copper tube connection(1) clean the oxide film, oil stain and sundries on the outer surface of the copper pipe, the weldment and the inner and outer surface of the pipe. After the outer surface of the pipe and the inner surface of the pipe are evenly coated with the brazing agent, the copper pipe is inserted into the pipe to the bottom end and is rotated properly to maintain a uniform clearance to remove the excess drilling agent;(2) for welding flame on the joints evenly heated until heated to the temperature of brazing, heated by contact with solder joints, pipe joints of high temperature melting solder to solder melting quickly, can be added to the weld heat side solder fill;(3) stop heating.
Connection method for air conditioner copper tube(1) air conditioning copper pipe connection, remove burrs and dirt in the pipe section, tube card, ring is sleeved on the outer wall of the pipe, the pipe thread interface, the snap ring is tightly pressed on the outer surface of the copper tube and the tube surface finish is tightly connected to the brass cut, cut burr, clean, use special expanding forming tools, expanding export processing into a cup or cone;(2) when connecting, the end of the cup or taper pipe is pressed into the copper pipe piece, the cup shaped or the conical outer surface by the screw thread interface of the copper pipe piece, and the pipe sleeve nut is locked to complete the tight connection;(3) the air conditioning copper pipe connection is directly processed into flanging pipe fittings: the copper pipe port adopts a special machine or a hand flanging tool, and is processed into flanging flanges. Through the steel flange connecting bolts complete implementation, tight connection, with a lower melting point than the timber and timber solder heating, in the material is not melted, melting, filling the gap between the joint of two materials, complete the brazing seam.
