Some time ago, in all the apartments and houses throughout the pipelines going from the metal pipes. Their combined by welding or threaded manner. Nowadays, technology has advanced a great alternative - polypropylene pipes, characterized by ease and convenience of use. Plastic parts are mounted with the help of special tools and equipment. The most simple and convenient device allowing to create a quality connection, a soldering iron for plastic pipe installation. The device is in demand among the artists who have installed in your home water supply and heating systems. Manufacturers each year producing new models and equipment before you buy, you must figure out what it is, different from the others and on what parameters need to pay Attention.
How does the soldering iron and how it works
Almost all models have the same design with a difference except that in the method of mounting nozzles on the heated surface. soldering iron itself consists of:
- Housing with a handle;
- Welding PETN (placed in a cast metal housing);
- thermostat;
- Set of special nozzles.
The device soldering iron can be compared with a conventional iron. Characterized by the device only for its purpose and form. Soldering irons, however, as the irons are two key executives - the thermostat and the heating element high-power, embedded in a flat or round housing. It depends on the shape of the body attachment structure of the working nozzles.
Each equipment comes with instruction, from which we can highlight the principle of operation: heater, connected to a network, it heats the stove, and she, in turn - the nozzle. The task of the latter - soften the material being processed to a viscous state, which facilitates the connection procedure. The thermostat is designed to maintain optimum nozzle temperature (about 260 degrees Celsius). They are controlled by the welding procedure of surfaces, preventing more melting than is required. If the working tip becomes hot, it is easy to overheat the joint and polypropylene will "flow" which reduces the diameter of the product or lead to its deterioration.
If it is not enough to warm the pipe, the connection will not airtight. Additional thermostat task - to protect the heating element (metal head will not melt). It is better not to consider cost of the device models, as their construction does not imply the use of high-quality temperature control, and a lot depends on him.
We should also mention the role of baits. It is recommended to choose a high-quality components for reliable soldering joint. Often different coating nozzles. Choosing a soldering iron, attention is paid to the thickness of the non-stick layer. The most stable is meant nozzle Teflon coating or metalized Teflon (even stronger). With their help it is uniform heating of the workpiece.
The parameters of the soldering iron of choice
power value
Choosing a soldering iron for plastic pipes is important to understand that the key parameter - power. It affects the size of the pipe and the warm-up device, respectively, and the speed of installation (if the amounts are large, then put the item in priority).
It may seem that when you choose, you can be guided only by the power of the soldering iron. And now, many are buying the device, which varies power from 1.5 up to 2 kW - this is not quite correct approach to the selection.
Businesses use simple formula which allows to choose an optimal power: multiplied diameter tubes used (in mm) 10 - this will be the minimum power value.
For example, to provide a spike tube 50 mm in diameter, power equipment should be less than 500 watts. Based on this model is divided into:
- Household - enough power to 1.2 kW;
- Professional - from 1.8 to 2.2 kW and more.
Useful tips
Soldering is used for soldering plastic pipes are usually already equipped with special nozzles, which greatly enhances its functionality. Some manufacturers have a peculiarity: they produced models support simultaneously up to two nozzles, so that the procedure soldering pipes with different diameters being implemented more quickly.
Nozzles may be coated with various materials.
Important information! The most practical coating - PTFE and Teflon metallized. Characterized by strength and uniform heating of the ends of the PVC pipes.
The heating temperature
On average, the maximum temperature of the heating equipment does not exceed 300 degrees Celsius. When choosing a device, you should pay attention not only on the performance of the working temperature, but also the ability to control it. During the work it is very convenient: in fact for the connection of one material enough to +50 degrees, and other needs all 300 degrees. Polyethylene pipes are melted at 220 degrees and 260 degrees with polypropylene.
Wondering "how to choose a tool", you should familiarize yourself with the controls and how generally monitored. Useful if provided Tally - display devices connected to the network and the level of heating. Here the task of the built-in thermostat - adjusted operating temperature, depending on the operating conditions. Some professional models are equipped with a special display, which displays information with regards to the current temperature. This high-quality devices, which work with easy and convenient - because in conventional models of temperature is intuitive wizard. When connecting the pipes with his hands there is always a chance of overheating - a useful feature here is safety shutdown. As for the conventional models, they just occasionally need a break, but it affects work performance.
How is soldered
Consider how to use a soldering iron. The procedure works as follows:
- Are cut perpendicular to the central axis of the pipe. If the end of the curve will be, it will greatly affect the quality of soldering;
- With the pipe end chamfer (cut place cleared of debris);
- Equipment put on the nozzle and it is included in the grid. When you turn on the red light. When it goes off, it will indicate that the device has reached the desired temperature;
- Heat up the work pieces. On one side of the nozzle tube is mounted on the other - fittings. Warming lasts about 6 seconds. The pipeline begins to melt and at this moment the connection is. To cool polypropylene takes less than a minute of time. During operation of the pipe joint is better not to touch it, otherwise all the work can be spoiled.
After soldering the workpieces used for its intended purpose. For better welding is recommended to place the tube in a horizontal plane. Works are easily performed and alone, without aides.
The advantages of a self-made soldering
The base of such a device will be improvised heater. Amateur Model easy going person familiar with the wiring and having a basic metalwork skills. Fans can assemble homemade homemade soldering iron and its key advantage - the availability. The downside is there is not enough high-quality soldering, Godea except for the amateur level.
Homemade device assembled from:
- Heating element. Suitable conventional electric irons, or rather its sole;
- Required attachments;
- Nickel-plated screw-nuts (needed to fix the nozzles);
- DMM having external thermometer;
- Clamps or other fasteners.
Top 5 tips for models of plastic pipes
Dremel Versatip 2000-6
