Household repairs are most often done by one’s hands without the help of specialists. As a rule, complex equipment is not required for applying decorative coatings, laying flooring and repairing individual structures. But work with utilities should be approached with utmost responsibility. Plumbing from time to time needs to update worn out contours, and in this case, you can not do without a special tool. Scissors for cutting plastic pipes will be the best solution if you need to shorten a long workpiece for subsequent integration into the system.
Tool Overview
These are devices for performing manual cutting operations, so they are often used in the domestic sphere. For professional use, versions with a similar principle of operation, but with wider functionality are intended - they are attached to the bed and are cut in a stream mode. The main difference between scissors for cutting plastic pipes, the photo of the standard model of which is presented above, is a solid construction base. As a rule, stainless and chromium-vanadium alloys are used for working bodies, which ensure high-quality cutting. There are models with roller functional organs, thanks to which you can get even better results. The edges of the pipes after processing with such a tool are smooth and completely suitable for joining.
The general principle of the tool
The specific mechanics of the operation depends on the type of scissors. Classical models provide impact on plastic material with cutting metal parts. In this case, the design is performed in such a way that the minimum pressure is required from the user himself. In addition, shears for cutting plastic pipes, depending on the design, can be adjusted to the technical characteristics of the workpiece. The simplest devices are intended for products with a certain diameter or, in the best case, can serve pipes of different sizes, but with a narrow range.
Varieties of designs of carvers
The standard option provides for the ratchet mechanism. In one part, the cutting part is located directly, and in the opposite - a special round recess for planting the workpiece. How do shears for cutting plastic pipes of this type work? The operation is performed by bringing the two handles together until a complete cut-off is realized. A slightly different principle of operation is embedded in telescopic models. In their device, a bracket-shaped housing and a cutting roller are provided, which in the process of conducting along the surface carries out spot cutting.
Versions of the tool for working with metal-plastic
For such tasks, a special version of the scissors should be prepared. These are precision type models characterized by the presence of a ratchet mechanism. But even among them, far from every model can cut metal plastic. As a rule, large modifications suitable for servicing large-diameter pipes are suitable. A wide cut-off area provides additional grip advantages, which makes it possible to process solid material. There are also automatic scissors for cutting plastic pipes, which can be used to carry out similar events, but they are less commonly used in the domestic segment. As a rule, if you need to cut the same metal plastic, a power tool like an angle grinder is used.
Preparation for work activities
To get a high-quality result, scissors and the pipe should be prepared accordingly. As for the tool, its functionality, reliability of the structure and accuracy in the direction of the cutting part are checked before work. For verification, it is desirable to perform several test operations on the waste material. This will allow you to evaluate how ready the mechanism is to create smooth edges. How to open scissors for cutting plastic pipes? This is done using two handles. The test procedure should be performed with maximum wiring in order to fully check the quality of the mechanism. In this case, the feed pipe should correspond to the diameter of the workpiece. The target material, in turn, is cleaned and lubricated with degreasing agents before work. Performing this procedure will eliminate the risk of slipping off the cutting part and improve traction.
Cutting technology
First of all, you should correctly outline the cutoff line. The segment is marked strictly according to the required size of the replaced part. If we are talking about telescopic models, then the workpiece is clamped in the corresponding niche, and then fixed with a screw. Next, the user scrolls the roller along the cutting line and the operation ends. How to use standard-type plastic pipe shears? Also, the workpiece is placed in the cutting area, and then, by means of the information of the handles, clipping is performed. It is important to emphasize that the pressure itself should not be produced sharply, but smoothly. Otherwise, there will be a risk not only to get uneven edges, but also a deformed pipe even outside the cutting point. After the operation, if necessary, you can refine the end of the workpiece with fine-grained abrasives. Sometimes, as an additional operation, plumbers also produce threading with another specialized tool. Although for plastic products this operation is less relevant.
How to choose the right tool?
The paramount parameter is the size of the pipe, in particular its diameter. A specific model should be selected for it. It is worth emphasizing that scissors with a large groove do not guarantee high-quality cutting of thin workpieces. Therefore, it is not worthwhile to purchase a tool "with a margin" in diameter. The size range varies from 35 to 300 mm on average. The choice should be made for a specific format or, in extreme cases, with small deviations of several millimeters. As already noted, the larger the capture area, the better the cutting will be. The material used to make scissors for cutting plastic pipes is also taken into account. Owner reviews especially recommend paying attention to the presence of anti-corrosion coating. The best solution is a stainless steel model. More resistant and durable alloys make the tool much more expensive.
Tool manufacturers
This tool is produced by manufacturers of construction machinery and equipment. In particular, Jonnesway offers versions for processing pipes with small diameters up to 28. The Kraftool assortment has a modification of 23381-42, which allows you to cut workpieces with a thickness of 42 mm. For universal household use, it is worth purchasing scissors for cutting Elitech 2110 001100 plastic pipes, which have a coverage of 16-42 mm. If we are talking about production communications, then a Gerat 63358 device may be required, thanks to which lines with a diameter of up to 300 mm are serviced. High-quality scissors for such purposes are also offered by domestic manufacturers. For example, the company “Encore” for 35-mm blanks has released a long-lasting and functional modification of 9631. As for the cost, in the initial segment it is easy to find options with price tags up to 500 rubles. Even large manufacturers contain in their ranges budget models for 200-300 rubles. Of course, as the diameter increases and the operating range expands, so does the cost. Professional scissors are available, on average, for 1.5-2 thousand rubles.
Conclusion
This tool is not the only solution for cutting pipes made of plastic. New technologies allow today to produce melt and heat treatment products for domestic use. However, the cost of such equipment is much higher than that of standard shears for cutting plastic pipes, which have a simpler design. But will this tool be enough for the full installation of plumbing communications? As already mentioned, depending on the tasks, it may be necessary to create a thread and additional grinding. It is also necessary to foresee the plumbing fittings through which the connection is made. For servicing the scissors themselves, it is recommended to purchase special greases that support metal surfaces in optimal working condition.
