During the installation of the pipeline rarely costwithout crimping operation. In essence, this is a simple action that a non-specialist can perform at home. However, for the qualitative implementation of the procedure, an appropriate tool is still required. Usually, press-fittings or crimping pliers are used for such purposes, which make it possible to provide a damage-resistant and tight joint with minimal physical effort.
Features of hand presses
There are several varieties of press mites,which differ in the nature of the principle of operation and performance. Usually distinguished between manual and mechanized battery or network models. The standard solution is considered the manual version. This option is suitable for working with pipes with a diameter of up to 26 m. That is, this tool is advisable to use at home with small workloads. It is more profitable to use a network or battery press for metal-plastic pipes where large volumes of work are to be performed. Also, electrical devices benefit from hand presses by providing additional features — for example, they provide lighting in dark rooms without access to artificial lighting. But such modifications and cost more expensive.
Main characteristics of the instrument
The main working characteristic is considereddiameter with which the tool can serve pipes. It is important to note that in choosing it is not enough to pay attention only to the maximum upper bar - for example, 32 mm. The fact is that each version covers a specific range of sizes. So, there are tongs for the press of plastic pipes, which work only in the corridor of diameters from 12 to 24 mm. Or there are more powerful versions capable of serving a spectrum of 16–32 mm. In addition, for ease of operation, it is important to take into account the characteristics of the rotation of the press head. Almost all modern models provide 360 ° torsion, but there are also exceptions. Especially when it comes to regular use of the device, you should consider its weight. On average, press tongs weigh 6-8 kg. The smaller the mass, the more power is saved in the process of performing working actions.
Manufacturers
Despite the apparent simplicity of the tool, itsfabrication and design development requires serious resources. Not every company can afford it. In the Russian market, in particular, high-quality press for metal pipes are represented by the brands ROTHENBERGER, REMS and Valtec. The company ROTHENBERGER produces a wide range of different crimping tools, as well as accessories for working with pipelines.
REMS brand products are structurally distinguished.advantages and high quality materials used in the manufacture of tools. No less remarkable is the Valtec press for metal-plastic pipes, which is mainly produced in the form of radial models. It is a practically universal sanitary unit, through which it is possible to serve not only metal-plastic, but also copper, stainless and cast-iron pipes. Another thing is that in each case the tool must be suitable for performance for a specific task.
Nuances of operating the tool
Usually the crimping action is performed.with pipes that could be deformed when cut. In this case, the calibrator should restore the optimal round shape and remove the chamfer on the inner edge. Further preparatory work is carried out. They consist in the installation of the nozzle, which will not allow the pipe to be deformed again when working with tongs. It is very important to carry out the correct equipment with liners and gaskets. This eliminates the risk of mechanical damage to surfaces. Now you can install a press for crimping plastic pipes in the operating position and, through physical effort, perform the operation. The quality of crimping will depend on how correctly the size has been selected - that is, the degree of matching diameters. The end result will be the formation of two metal arcuate strips, which will ensure the conjugation of different sides of the pipes.
How much do press fittings cost?
The simplest model of press mites is estimated at 3-4thousand roubles. As a rule, these are models from Russian manufacturers, which differ in small dimensions and modest sets of nozzles. Versions from the above manufacturers, even in the entry-level versions, cost about 10-12 thousand rubles. Professional hand tools for crimping are available for 15-20 thousand. It is important to note that such devices are often supplied without any attachments, and their advantages are expressed in high quality mechanics and versatility. If the price of the press for plastic pipes is less than 5 thousand, then it is more likely to be a short-lived tool of poor quality. True, such models are also found in the rulers of large manufacturers. Low cost in this case will be due to the small size of the press-ticks, their weak ergonomics and focus on the performance of work with diameters in a narrow range - usually small.
How to choose a press for plastic pipes?
If you plan to purchase a model for frequentapplications in work with pipelines, then preference should be given to universal tools, that is, those modifications that are able to serve the widest range of work. By the way, for use in everyday life is quite suitable device that works with formats 10-16 mm. Larger diameters are still serviced by experienced professionals. If you choose the tongs for the press of metal-plastic pipes that form the responsible lines of the main networks, then it is worth thinking about the feasibility of buying a hand tool as such. Perhaps the best solution in this situation would be a network or battery device. But, on the other hand, the complete autonomy of manual modifications to work on remote de-energized objects is also a significant advantage, and this must be taken into account.
Conclusion
Plumbers practice a variety of waysrealizing the connection of pipes. Some of them are characterized by ease of use, while others allow for long-lasting joints with a high degree of tightness. A squeezing press for metal pipes rather belongs to the second category of connection techniques. Provided quality work in this way, you can organize a reliable pipeline network with minimal cost. As for the availability and ease of this method from the point of view of installation, it is certainly not the easiest, but the result obtained is more likely to justify technical troubles.
