To date, the production of pipes has gained considerable momentum. Evidence of this is the large number of varieties of models, differing from each other, except diameter, composition of the material. Each species is characterized by its advantages and disadvantages. But according to most experts, the best option is polypropylene products, metal and polyvinyl chloride (Pvc).
Scissors for polypropylene pipes - a simple and convenient tool
Types of devices for cutting polypropylene pipes
Polypropylene pipes are sold in straight segments up to 12 meters or bays. Therefore in the course of installation often there is a necessity in their cutting with the subsequent welding.
As you know, money love account. With this in mind, the desire of any person looks quite natural, faced with such a problem, to buy high-quality scissors for cutting of polypropylene pipes at the optimum price. Here it is important to understand one nuance. If there should be a small repair, during which only a few segments of the pipeline will be manufactured, cheap scissors will do. Their blades are made of steel not the most expensive brand. Therefore, compared to high-quality counterparts, they blunt much faster. But why pay more, if you use scissors only a few times?
Another thing, if you plan to be engaged in laying of polymeric pipes or their repair often (in a large household or at a professional level). In this case, you can not do without a quality tool.
There are several types of devices for this purpose in the retail network.
There are several models of tools for cutting pipes on the market
Precision scissors for cutting plastic pipes with ratchet mechanism. They are quite simple, reliable and easy to use, and their value is within the average price range (to 20 dollars). Along with the quality of the cutting tool, the diameter of the pipes to be cut is also taken into account here. If the value of this parameter does not exceed 35-42 millimeters, scissors will cost less. When you plan to separate pipes with a large diameter (63-75 millimeters), the price of this type of tool increases significantly.
Automatic scissors, which have the shape of a pistol. Essentially, these are close relatives of these products. Although such scissors for polypropylene pipes are more expensive, housekeeping masters prefer them, because with their help you can cut pipes of any diameter, even the greatest. Automatic scissors are especially relevant there, where it is necessary to cut the area, which runs close to the wall. At the same time effort, which is added by the brush to users while working, decreases.
Roller pipe cutters. This tool is very easy to use. The design of an inexpensive option includes a disc blade, which is removed or approaching the surface, cutting with a threaded drive. Turn the tube slides along the rollers, located on an arc of C-shape. It is mounted opposite the blade. A more expensive version of the roller pipe cutter is made in the form of scissors, equipped with a ratchet mechanism.
The roller pipe cutter is equipped with a disk blade, with which it is very easy to cut the pipe
Electrified pipe cutter. Electric tool, essentially, is an advanced design of manual devices for cutting pipes. The only difference is, that the scissors for cutting polypropylene pipes do not work due to the muscular strength of the operator, and are driven by an electric motor, guillotine control and fix fasteners. The technological process is very simple. Insert the pipe into the locking unit, click on the "Start" button, waiting for the moment, when the guillotine knife completes the work and we get a perfectly smooth segment. And this without any effort!
The disadvantages of electrified pipe cutter include its inability to work with products, whose diameter exceeds 42 millimeters, as the sizes of fastening do not allow to fix pipes with big value of this parameter.
Useful to know! Pipe cutters and scissors for plastic pipes are hand tools. This means, that they are activated by the muscular strength of the performer. Therefore, carrying out work in large quantities can cause significant fatigue.
Cutting of metalplastic pipes
Products of this type successfully combine the best characteristics of metal pipes, a time of unconditional domination which sank into oblivion, and plastic samples. Metal-plastic pipe is nothing else, than aluminum pipe, insulated inside and out with plastic. That is, in addition to the polymer, it contains a stronger material - metal.
The cut of the pipe when using scissors will be smooth and without large burrs
This design places additional demands on scissors for cutting metal-plastic pipes. In particular, they must be equipped with hardened blades, wedge-shaped. in addition, there are also features of operation of this tool. So, to get a good result, when cutting the scissors must be turned around while squeezing the handle. But due to the presence of a rack, metal-plastic cutting is quite simple. The process itself is perfectly controlled visually.
Another obvious plus is, that the use of special scissors for cutting metal-plastic pipes is a completely waste-free technology. After this procedure, you will be free from the need to remove crumbs and will be able to begin the assembly process without delay.
When cutting the pipe must be bent at the joint. To do this, use a special device - a pipe bender. Without such a simple tool to qualitatively bend the pipe yourself is unlikely to succeed. Attempting to do so involves the risk of damaging the inner aluminum tube, employees also act as the framework of the product. This will cause premature failure of the entire pipeline.
Importantly! Using the tool, not intended for work with metalplastic pipes, also threatens to get an uneven cut at the exit. However, even if the aluminum component remains intact, the connection of the pipeline elements will be leaky with all the consequences, the ensuing consequences.
Cutting of polyvinylchloride pipes
PVC pipes are among the most popular materials for sewer systems. This scope is conditioned ??their resistance to aggressive substances, which are abundantly present in domestic and industrial waste.
Cutting large diameter pipes should only be done with special tools, not a hacksaw
These products are made of plastic. With this in mind, the same tool can be used to cut them, as for working with polypropylene pipes. So, "Stuffing his hand" on such products, question, how to use scissors to cut a plastic pipe in this case will be irrelevant. But there is one nuance. As mentioned above, PVC pipes are most often used for installation of drainage systems of human products.
However, in the requirements of the relevant Snipe specified, that the sewer pipe must have a large diameter. However, the value of this parameter plays a paramount role. The peculiarity concerns the final stage of cutting: without the use of scissors for PVC pipes in the form of a roller pipe cutter to make quality trimming will not work. Therefore, the oxidized crust will remain, which may lead to the unsuitability of the subsequent connection of pipeline segments.
Products of leading brands
In this segment of the modern market is represented ??products of many manufacturers. However, the most popular are the products of the following foreign companies: Rothenberger, Reed і General. Information about their scissors for cutting metal-plastic, polypropylene and PVC pipes are presented ??in the summary table below.

After cutting, the cross section of plastic pipes changes. A calibrator is used to restore it. It not only returns the slice to a round shape, but also removes the inner chamfer. This tool is inserted into the pipe and rotated several times.
Useful to know! Than, included in the design of the calibrator, clean the pipe from the chamfer completely, only if the cut is made strictly perpendicular to the longitudinal axis of the pipe and the calibrator itself is NOT skewed.
Choosing a tool for cutting pipes, follow the manufacturer's diameter recommendations, cutting products, as well as their correct placement relative to the cut line.
