Many residents of multi-storey or private homes built in the last century, trying to replace the old system to the Communications, made of modern materials. Such a material is inexpensive but reliable metal and plastic from which the pipe produce both heating and plumbing. The nuances of the installation of reinforced plastic products are many, but should stay on the main - connection and soldering pipes.
The list of tools needed for work
Performing calculations and purchase the necessary amount of material we should consider the acquisition of the necessary tools. For the installation of plastic pipes, especially the hands, some pliers, flat screwdriver will not be enough, so it's better to spend a little bit, but have everything you need at your fingertips.
That it is necessary to purchase:
- Cutter. A tool that should be available in the first place. With this device you can get smooth edges, no burrs or other damage.
- Press ticks. Refer to obzhimochnogo tool category, using which two tubes can be connected by putting them on the press-fitting.
- Calibrator. The Calibrator is used to correct razvaltsevaniya in which the surface of the metal-product is not damaged.
- Flat skimmers. If the cut has been executed correctly or curve, with the help Flat skimmers it is possible to give the correct shape.
- Set carob keys. For more savings you can purchase a wrench.
After gathering the necessary tools, you can proceed directly to the mix. But this should be familiar ways connections or soldering metal pipes.
What is a compression fitting and how to use it
Compression fittings are often used not only domestic masters, but also a professional plumbers. So why are they so popular? The answer is simple: because a lot of positive qualities and ease of installation.
- To set the compression fitting does not require special equipment, just to have enough adjustable wrench handy.
- Such products suffer even burrs along the edge, so the cutter can not be applied here.
- It is not necessary to apply Flat skimmers and calibrator.
Installation sequence compression fitting as follows:
- Nut, which has a free wheeling, and tightened after installation, is put on the end product.
- Shank obvorachivayut tow several times, for greater tightness of the joint and is inserted into the product.
- At the base of the fitting is put on the fixing nut. One wrench to hold the item housing, second - tighten the nut.
The simplicity of the installation can be deceptive and not many artists get home to perform a proper connection on the first try. Tightening the lock nut should pay attention to the force applied as a compression fitting body may crack.
Important! Before installing the product, be sure to check that all O-rings, as well as fitting gaskets, which provide the required level of sealing. In their absence, the connection is reliable and require emergency replacement.
Install push-fitting with his own hands
Maximally simplified product for installation is even adjustable wrench is not necessary, only the right hand. The sequence of installation is as follows: take a push-fitting and the pipe inserted in it until it stops. To determine the force, just look at the special test hole - as soon as it may seem the end of the article, you can stop pushing.
Push-fittings are particularly relevant when the question is how quickly the composition pipe to connect with metal. The benefits of this compound is very much:
- As mentioned earlier, it does not require tools for installation. Just push-fitting and articles to be joined.
- Push-fittings have a long service life, made of durable and reliable materials.
- You can be walling in the wall, in contrast to the compression fittings. Very handy when there is no desire to constantly monitor and tighten the connection.
Do push-fitting weight advantages, but also has one drawback - the high cost. Cheap products is better not to acquire, as the price decreases in proportion of their operational life. Should apply to the plumbing shop where select connections from known manufacturers.
Press fittings
Very similar to the compression products, but with some differences. Press-fitting may be mentioned more productive form of the compounds, since they have a long service life, but require the use of an appropriate tool. If done correctly, the installation press fittings may be laid in the walls.
The main differences from compression products:
- Low rise rubber seals, respectively - the best tightness. Seal tightly compresses plastic products on the inner diameter.
- Locknut replaced obzhimochnaya sleeve for gripping and which are used pressing tongs. The sleeve is made of stainless steel, is not subject to influence of moisture in the water system. It is because of the use of obzhimochnogo tool, press fittings may be mounted in the wall.
The sequence of assembly is the same as in the case of compression products. Put on a fitting on the end product and tighten by means of press jaws. The installation process is simplified because of the absence of the locking nut.
This kind of fitting has virtually no defects except expensive tool. Price ticks crimping sleeves on plastic pipes starts from 6000 rubles. Over 10,000 mark already underway professional tool category.
Soldering metal pipes
The main types and methods of joining metal pipes have been discussed above, it is now necessary to move to the diet. It should immediately designate a list of tools needed for soldering plastic products. To require:
- Soldering or welding machine for the soldering of plastic, polypropylene, and plastic products. The average cost is from 1500 up to 2500 rubles. A higher price means an additional indication or more modes.
- Sealant. It is better to choose a sealant that is not affected by high temperatures, but as a cheaper option available for purchase and easy.
- Tow. Which is used in almost all the plumbing works.
Soldering or welding machines are divided into domestic and professional models. The main difference between them - professional soldering irons can produce soldering pipes with a diameter greater than 50 cm, but for domestic purposes it will be overkill.
How to solder metal pipes:
- Exactly cut the pipe to ensure that the edges had no burrs. If the edges are uneven, or the surface will suffer, the ration will not bring a positive result, and the entire process will have to be repeated again.
- Enable soldering iron and heat it up to the rated temperature. I tip part formed by a cone portion of outer heat pipes. For different diameter on the corresponding nozzle set soldering.
- Set the nozzle one size smaller than the previous and efficiently heat the inside of the plastic products. Nominal temperature at which the soldering is made of pipes, is 180 degrees Celsius.
- After heating the outer and inner parts to connect two pipes together. Wait until the product cool. Now soldering is complete.
How to bend the composition pipe
Very often, after the connection of pipes, the design has to arch in the right direction. If installation and connection technology chosen quality plastic pipes, then onto the fitting or soldering is not affected. Still bending the pipe is better to perform properly, and for this there are several interesting ways.
It is best to use a hair dryer building. Quite a bit heated portion to be bent, and then his hands to give it the desired shape. The heated composition pipe bends easily and is not deformed. Keep in mind that you can not avoid overheating tubes, which can lead to its damage.
Sometimes the bend of reinforced plastic products used rigid spring, precisely selected diameter. Spring dress in a tube and push into it, it can achieve the necessary rigidity. The middle of the fold and the middle of the spring must be matched exactly. And so then it could get to one end should be firmly primotat metal wire.
You can also use the sand, it is necessary to fall asleep inside the plastic products so that it is evenly distributed throughout the pipe, without hollow spaces. Then the selected portion to bend slightly heated and smooth motion impart the desired shape. When using sand, metal tubes are not deformed and remain intact throughout.
If you want to hold the folds of articles often and in large quantities, it is best to buy a tube bender - specially made for this tool. Of course, the cost of it is great, but it allows you to simplify the task. Some handyman doing bender at home, using the materials at hand.
