Soldering Copper Pipes – How to Solder a Copper Pipe
copper tubes are very useful, containing water, refrigerants, or air. therefore, they are very often used in the transport of such materials in various appliances in the house. however, for bending copper pipes must join two tubes at right angles with the installation. this can be done by soldering copper pipes to each end of the device at the point where the tube must follow.
what is soldering?
welding works in a capillary route. when the tube and fitinga are heated, soldering material is touched to the hollow. heat-melt welding material, and in time the material is capillary intake in the joint sealing. after soldering material cool, the vacuum becomes, thus forming the sealing of copper tubes and fitting tightly together. it is important that the soldering material has lower melting point of copper. otherwise during the heating of pipes to the melting of the soldering material, metallic pipes may leach.
steps for soldering copper pipes
the reduction of the tube: cut the pipe of the necessary length. since copper is a soft metal, it can be sliced neatly, using a pipe cutter. however, in the case of larger tubes, one saw can be used. if you are using the saw, then to ensure that all share at the end of the tube were submitted. otherwise, the tube can expire.
cleaning of pipes: cleaning of pipes and fittings, and making them without rust is an important step for perspiration of copper tubes (welding). emery paper, ?mirgel cloth and steel wool would be good for cleaning the outer surface of the tube. however, for the cleaning of the inner surface of the tube and fitinga brushes for cleaning will be more effective. these brushes are available in different sizes. for cleaning of brushes, which conform to the dimensions of copper tubes and those of the obkovite can easily be purchased from the market. map the liberal layer of techniques to the interior of the installation and the outside of the tube.place of installation of the end of the tube and moving pipes or installation of back and forth, so that the flow can be distributed evenly over the surface. fl?sovane of sites ensure that even the smallest traces of darkening is removed. in addition, it reacts with fused spelter and removes impurities from it. this helps increase free to circulate in the hollow.
thermal energy: place the tube in the assembly. now you’re ready for soldering copper pipes. heating technique to be used depends on the dimensions of the copper tube. if you are using small tubes, then using a propane torch will be sufficient. however, for larger pipes must use acetylene torch plumber. since copper is an excellent conductor of heat, therefore heating installation at one point or the point of the pipe near the joint will work. keep the flame there somewhere, so that the temperature of the object you heating reaches the melting point of soldering material. although the 10-20 seconds will be sufficient older pipes, may take a little more time. once you think that the hollow has reached the correct temperature, contact welding wire during the joint. if it melts, it means, the joint is heated to the correct temperature. testing of temperature touch soldering wire hollow. once you have enough practice, you will get cakata of the correct temperature easily.
soldering: touch seamless tel hollow, once you are sure that it has reached the temperature of soldering. binder will melt and the learner in the hollow between the tube and fitinga by capillary action. in the event that the pipe is small, there is no need to soldering wire throughout the circumference of the hollow. as the glass melts, it will be downloaded in the hollow along its entire circumference. once fused spelter began to pour, this indicates that there is no more need for soldering material, fixed to the hollow.be careful, so it is not too much of the soldering material melts and accumulate inside the hollow, since will be formed podutini, which will impede the flow of water through the pipe.
zabrsvane joint: once the tube is cooled a little, take an old rag, collapse it several times, so that it is sufficiently thick, to protect your finger from the hot metal. you also may be a little ovla?ni. now quickly wipe excess equipment and techniques far from jointly to ensure that there are no spots of equipment and techniques. nothing looks better than pure bright shiny joint group of silvery gray in the hollow. in the event that you are using the wet carpet, it may cool the tube quickly, leading to the formation of spots of welding material during the joint. if this is the case, pretoplane joint to pulping and wipe the excess equipment and techniques.
precautions to be taken
always wear protective goggles while soldering.
never increase the exact top.
wear gloves while application flow such as the chemical can damage the skin.
use a heat shield, if you have any combustible substances which are close to the welding area.
keep the fire extinguisher in the vicinity.
soldering is a simple process of plumbing that can be carried out at home. once you master this technique, other than soldering copper pipes, you can cope with the number of home repairs.
