If it is necessary to dismantle the pipeline, use the appropriate tool. For such needs, specialists use pipe cutters that allow the operation to be performed with high accuracy and accuracy. On the market, this tool is presented in several forms, each of which focuses on a specific type of pipe and material. So, there are special scissors for polypropylene pipes and cutting polyvinyl chloride.
Tool device
Designs vary depending on the type of tool. Traditional models of this type are a ratchet mechanism consisting of two working parts that form the handles and cutting surfaces. However, only one of the parts performs direct cutting, and the other has a specially shaped recess for accommodating the pipe. A telescopic scissor device for polypropylene pipes is also common, which differs in a staple-like body and the presence of a drive roller. On the axis on the other hand, a carriage with guides is provided. By manipulating the functional mechanisms, the user can precisely fit the tool to the dimensions of a particular pipe and easily perform cutting. In this case, the action of the blades is ensured during the rotational movement of the workpiece around the axis.
Main characteristics
When choosing, experts recommend taking into account two main characteristics: the material of manufacture and the range of diameters with which scissors for polypropylene pipes in a particular design can work. As for the minimum size, it can reach 3 mm. And here it is important to consider that the possibility of placing the diameter in a special recess does not mean that the model is designed to work with this size. Large scissors can be deformed too small in thickness of the pipe, so you should accurately compare the capabilities of the tool and the characteristics of the workpiece.
The maximum diameter reaches 50 cm. These are already professional scissors for polypropylene pipes, which are close in design to industrial units. Equally important is the accounting of the material from which the tool is made. Typically, manufacturers offer stainless steel models to work with plastic. In this case, it is worth considering in more detail the alloy used in terms of the ability to maintain the quality of the cutting surface.
Varieties
Classification of scissors of this type provides for their separation according to the principle of operation. It has already been mentioned that devices can have a roller mechanism, but precision and automatic models are also found. In the first case, the construction is provided with a ratchet and can cope with large diameters in excess of 30 cm. If a more productive apparatus is required that can cut pipes with a diameter of 50 cm, then automatic scissors for polypropylene pipes in the form of a gun are used. This option is more expensive, but it has very significant advantages. First of all, this is universality of application, since the design allows cutting even thick-walled production pipes of large diameter. Another thing is that only plastic is available for processing. Another quality that distinguishes automatic pipe cutters is to save the user from unnecessary power manipulations.
How to choose the best model?
The practice of using scissors for plastic pipes shows that a high-quality tool can confidently cope with its tasks in any design, providing convenience and ease in the process. Experienced plumbers recommend paying attention to work surfaces. For example, many owners note the following problem - because of a weak spring and thin steel, scissors are crookedly cut. Polypropylene pipes can have any size, since the working defect is caused by the design. Therefore, the choice should take into account such a nuance as the reliability of the power mechanical base. But, of course, do not forget about ergonomics, which also affects the quality of cutting. The preference is given to thick handles, providing a comfortable and tenacious grip, not overloading the palms.
Manufacturer's Reviews
The most reliable, strong and durable models are produced by Valtec, KRAFTOOL and Jonnesway. Users note that manufacturers carefully approach the implementation of power mechanical units and do not forget about the aesthetics of the appearance of this tool. True, representatives of these families have one common drawback - high cost. The initial segment is represented mainly by domestic scissors for polypropylene pipes, the price of which varies from 2 to 5 thousand rubles. In particular, users distinguish “Enkor”, “Bison” and “SibrTech” models from this category. The owners note that the products of these brands, although not distinguished by the ability to cut thick pipes, perform qualitatively standard tasks with processing small and medium diameters.
Conclusion
Finding a quality tool is not difficult today. However, he will have to pay a considerable amount. In most cases, work with plastic pipes is carried out as part of household repairs or simple construction operations to update plumbing equipment. In such events, scissors for cutting polypropylene pipes, which have high power returns and the ability to cut large-format products, are not always required. It may well be limited to a universal model costing about 5 thousand rubles. If responsible work is ahead at public facilities with large-diameter pipes, then you can consider the option of a full-fledged manual pipe cutter with an automatic mechanism. Such a decision and the wizard will relieve unnecessary physical activity, and as a cut, it will not yield to alternative tools.
