The increase in the use of new materials in construction, made the pipe cutter for polypropylene pipes necessary tool when carrying out plumbing work. Products made of metal-plastic, polyvinyl chloride, polypropylene are installed in pipelines of hot and cold water supply systems, heating systems and waste disposal.
When assembling a polypropylene system over an extended section, it is necessary to adjust the inserted pieces to the size with a PVC pipe cutter in place so that the quality of the joints does not suffer. For this, it is important that the cut is strictly perpendicular to the longitudinal axis of the pipe without flattening (the result is a regular circle, not an ellipse). Where this is not always possible, a manual calibrator is used after the pipe cutter, which restores the circular cross-section with a reamer.
The cutting process can be carried out using 2 sources of energy: electrical and muscle. Structurally, the difference between an electric pipe cutter and a manual one for plastic pipes consists in installing an electric motor, which ensures the operation of the knife and clamps. The operator's job is to feed the polypropylene blank according to the mark made up to the control mark in the window of the device, pressing the power button. The maximum machining Ø is 42 mm. Such models are used when it is necessary to quickly obtain a large number of segments along individual size... On one battery charge, you can make about 180 cuts, work continuously for 35 minutes.
Due to the greater autonomy (there is no reference to the amount of charge that the battery colleague has), the possibility of using it in any conditions, intrinsic safety in gas hazardous environments, more often in the plumber's tool kit, manual pipe cutters for polypropylene pipes for the desired section are included.
Such a specialized tool as a manual pipe cutter for polypropylene pipes is quite simple in its device, easy to operate. The principle of operation of the cutting mechanism is of 3 types:
Any plastic pipe cutter will not be a universal cutter. When choosing a tool, it is imperative to pay attention to the data of the passport, which indicates the maximum Ø of the pipe, as well as the material that can be cut. Models for cutting blanks from steel, cast iron, non-ferrous metals, PVC pipes are specialized by the manufacturer for specific parameters.
Ratchet mechanism
One handle ends with a tool steel knife, the other ends with a semicircular pipe stop. Squeezing the handles with the palm, cut along the mark on the polypropylene wall. The return of the blade makes the ratchet.
Already according to the principle of operation, it is clear that such a device does not cut parts of large PVC pipes for the sewer. For small sections of single-layer material (Ø 5 - 30 mm), the tool is easy to use. Performance is determined by the fitness of the worker's hand.
Guillotine
In this case, the blade descends evenly across the entire width. The most simple model acts by feeding the stem by rotating the handle. Slightly more complex is the device in which the force is transmitted from the lever pressed by the operator.
The transverse passage of the guillotine is larger than that of the scissors. Various modifications reach Ø100 mm coverage, most models up to 70 mm.
The straight stroke of the cutting part creates a deforming effect on the walls of the polypropylene workpiece. Therefore, as the pipe cutter separates polypropylene pipes of large diameter, the force is gradually increased, and then, if necessary, calibrated.
Roller varieties
The roller pipe cutter for plastic pipes neatly fulfills its task due to the fact that the cutting edge does not just press on the wall, but rolls over it. For a pipe up to Ø 50 mm, one disc made of chrome vanadium or other tool steel is sufficient. With an increase in Ø up to 100 mm, their number increases to 3 pieces.
The telescopic structure consists of:
- staples (steel C-shaped embrace of the workpiece);
- cutting rollers;
- support roller carriages;
- guide;
- a screw handle that sets the feed of knives to cut material.
The clamp is rotated around the pipe, gradually increasing the pressure of the rollers on the plastic. The first turn will be a control one. Check the correctness of the circumference of the groove left by the hard disk. If you get a trace in the form of a spiral, it is better to move the mark and start over. When the roller has confidently plunged into the workpiece body, the force is increased to such that the rotation is smooth, without jerks.
Unlike metal rods, polypropylene and other plastic products do not need to be wetted with oil under the cutter. Here it is only important to control the effort.
Cutting the edge of the pipeline, mounted close to the wall, floor, allow models with a shortened handle. A small head protrudes on the bracket for rotating the feed stem.
How to use
When working with a manual pipe cutter for polymer materials, 2 parameters of the operation are constantly maintained:
- clamping force of the part;
- rotational speed.
To obtain a stable product quality, it is better to use models with guides that fix the position of the workpiece.
Sewerage systems are made of large diameter polypropylene pipes. For such work, special models have been developed that process Ø 160, Ø 350 mm. They are equipped with sets of interchangeable discs for walls of different thickness. The clamps maintain an angle of incisors to the wall of 90 °. Additionally, a chamfer is removed (angle 15 °).
Rothenberger tool benefits
Care and maintenance throughout the entire service life will preserve the instrument's performance and accuracy.
When installing indoor water supply, sewerage and heating pipelines, plastic pipes have to be cut in large quantities. Using available tools for this is not recommended due to the many potential problems in the future.
You need a professional tool for slicing. And it is better to take a special pipe cutter for polypropylene pipes, the use of which guarantees a smooth cut without burrs.
We will show you how to choose equipment for cutting polypropylene pipes, describe the device and principle of operation, and also outline the main criteria for choosing pipe cutters.
In stores, there are a variety of tools for cutting polypropylene (PP) pipes. These are both manual mechanical and electrical devices.
Each of them has its own merits. The most suitable equipment should be selected based on the scope of work and their complexity.
Polypropylene pipes can be cut using scissors or a roller tool - the first option is cheaper, and the second is more efficient in work
When choosing equipment for cutting polypropylene pipes, the main attention should be paid to two points:
The body material of such equipment is usually made of metal. And it's best when it's aluminum, not steel. The pipe cutter with aluminum handles is lightweight and requires less effort. When cutting soft polypropylene pipes, no extra effort is required. The aluminum tool will cope with the arising loads without problems.
The pipe cutter can have either replaceable or non-replaceable cutters. Sooner or later they will wear out. In the second case, the toolkit will have to be bought again. However, if the cutterbar is needed for one-time work, then it is better to take a cheaper model with non-replaceable equipment.

Due to inexperience, the slightest tilt in their hands leads to the formation of a curved end, which then has to be undermined. And if the pipe is also crumpled, then it will need to be straightened from the inside with a calibrator.
Pistol pipe cutters with a ratchet mechanism belong to the same type. They are much easier to work with. Efforts for cutting have to be applied very little, and the cut is smoother.
The return of the knife to their original position occurs altogether as a result of pressing the button due to the spring. This is the best option for cutting polypropylene pipes with thicker and harder walls.
The next type of pipe cutter is roller. He has one or more rollers in his design. This tool looks like a hook. Inside this hook there are movable wheels on which the cut pipe rests.
The cut itself is made by another already cutting roller-knife, which is extended from the handle on a telescopic extension.
Due to the presence of a telescopically extending cutter in the design of the roller pipe cutter, it can cut pipes of various diameters - they only need to be of sufficient section to fit into the hook
Cutting polypropylene occurs as a result of turning the pipe cutter around the pipe clamped in it. It is important here to rotate it so that the cut line in the plastic does not go away from the starting point.
The cutter roller should end the circle at the same place where it started. If the pipe walls have to be cut thick, then the turn around the pipe will need to be done several times, gradually pressing the cutter deeper into the plastic by turning the screw on the handle.
This type of pipe cutter also includes a rotary roller tool with several cutting rollers on a circular clamp, but it is more intended for cutting products from steel and cast iron.
At correct use and precise holding of the knife along the cut line, as a result of the use of a roller pipe cutter, it turns out to be perfectly flat. According to this indicator, it is comparable to the guillotine.
But it cuts pipes much faster, but it also costs more. Plus the slightest inadvertent shift of the knife to the side leads to the appearance of burrs at the cut site, which must be further removed.
When cutting polypropylene with a roller pipe cutter, do not overtighten the handle by pressing the blade too hard against the surface to be cut. Microcracks can form in the plastic, which will reduce the strength of the pipe and can lead to chips at the end.
Everything should be done smoothly and slowly. This is especially true when working with thick-walled and large-diameter sewer pipelines.

The technique of making a loom for the embroidery process is very simple and easy. You can independently create such a device to facilitate the creative process with a minimum of effort and time. It will take only about an hour of free time from embroidery and about three hundred rubles.
Even the most inept girl can build such simple equipment. The proposed technique for making the device will allow you to seamlessly see the seamy side of the product, since the machine provides a rotating frame part for a full rotation of 360 degrees. In addition, such a machine is quite convenient in terms of fixing the hoop frames, or for installing a do-it-yourself frame from PVC pipes.
So, for such a machine model, you will need to purchase PVC pipes intended for laying electrical lines. They are readily available from any specialist electrical supply store. PVC pipes, with the help of which water pipes are created, are unacceptable in this case, since they are connected using special equipment, and the pipes for electrical wiring are perfectly fixed in the grooves of the connecting part.
Necessary materials:
1. Saw for metal products;
2. Wing bolt 5 cm long, 2 pieces;
3. A PVC pipe with a diameter of 2 cm;
4. Corner fittings and tees;
5. Fasteners for plastic products in the form of half rings;
6. Seals made of rubber in the amount of 2 pieces;
7. And, of course, the main thing is striving and perseverance.
You need to understand that the parameters of the machine directly depend on the original size of the hoop frame. Therefore, it is initially necessary to make the design of the frame. To do this, you need to cut off four pieces of pipe, which are connected to each other with four corner connectors.
Further, it is necessary to assemble fasteners for plastic pipes into one fixing device, for this you need to fasten two fasteners with a bolt, and fix a rubber seal between them.
The third stage is the process of fixing the frame-hoop in fasteners, the diameter of which is 2 cm and 2.5 cm.The hoop itself in the form of a frame must be made of polyvinyl chloride pipes, the diameter of which is 2 cm. which is 2.5 cm.For the construction of the machine, a fastener with a diameter of 2 cm is suitable.
So, focusing on the frame, it is necessary to cut the pipe for the device of the machine tool. You need to be careful and do not forget to observe the required step of 15 mm, which is equal to the thickness of the two fasteners. Subsequently, the cut pieces of pipe must be connected using adapters - triple and angled. Any existing metal rod must be warmed up and with its help punch through two holes for the subsequent fixation of the frame with screws and fasteners. Then, you need to fix all the blanks and connect with a bolt.
The configuration of machine tools can be very diverse. It all depends on the location of the machine, desires, design skills and estimated dimensions. The machine can be set up for embroidery on a table, on a sofa, or on the floor. All this affects the height of the machine. In addition, if necessary, you can make additional storage locations for the entire "inventory". These can be additional shelves for drawings, cases for needles and threads, as well as boxes for fabrics.
Such a simple machine is quite convenient in operation, does not require much effort when setting it up, and is also a lightweight design, which is very practical in small room.
As a result, after recreating the entire action plan, you should get an embroidery machine of the following sizes:
1. The hoop in the form of a frame measuring 45 cm long and 30 cm wide;
2. The base of the machine in the form of a frame for the desktop version with a length of 55 cm and a width of 35 cm. will provide better stability;
3. The elements on which they are fixed are 45 cm long;
4. The bar for placing additional storage places must correspond to the length of the machine base pipe, it has a length of 55 cm;
5. The pipe, which is designed to hold various cases, should be about 15 cm long and connect the base of the machine and the bar for additional storage space;
6. The height of the machine for the table should be about 25 cm, in the case of manufacturing a floor structure, its height should be 75 cm;
7. Holders for lighting fixtures and a case for drawings should have a length of about 20 cm, their number is determined purely individually, but they are usually made in an amount of 4 pieces.
A support device for various additional elements, such as organizers for sets of needles and threads, can be made completely separately from the machine. During the embroidery process, a separate structure can be placed near the machine. This is quite convenient, since there are no unnecessary obstructing parts on the machine, and you can reach the right tool easy and fast. Fixing pipe fittings are attached to the holes made on the inside of the additional part. If it is necessary to have several cases or organizers, it is necessary to fix several pipes horizontally with fasteners. One of the three pipes, the top one, must be secured using an angle fitting that has a 45 degree angle. If desired, you can fix two or more additional parts on one horizontal pipe, taking into account the length of each of the parts. That is, if it is necessary to fix two cases for one mount, the length of each of them is 28 cm, then the length required pipe should be 56 cm long.

Once I watched as children build towers from LEGO bricks, and next to them lay polypropylene pipes and fittings that remained superfluous after the arrangement of the water supply in the house... And then an amazing idea came to me: why not use them as parts of an "adult" designer and make useful household items from them? Having started to create, I got carried away to such an extent that the materials had to be bought in addition, but read on what came of it.
Note that using plastic pipes to assemble various functional structures is far from my invention. People everywhere have long and quite successfully followed this trend, not limited to the use of such wonderful material for the installation of pipelines alone.
But I want to tell you what exactly prompted me to take this step, in addition to the type of children at play described above:
An impressive list of advantages, which I personally supplemented for myself with the opportunity to once again feel like a little child creating "castles in the air", turned out to be convincing enough to get down to business without delay.
It is difficult to call a greenhouse just a craft; rather, it is almost a building. But, nevertheless, plastic pipes do an excellent job with its construction. The finished arched structure will decorate the site and will provide you with invaluable assistance in growing many types of plant crops. In general, every gardener will understand what the speech is about, right there I want to describe the features of the installation process itself.
That such a building is not suitable for year-round operation, since it will not withstand the harsh winter weather conditions... So it's better to limit yourself to the spring-autumn period.
The main elements of the structure:
Construction instruction:
As a result, I got a wonderful summer greenhouse, which I safely disassembled in the fall and hid it in the utility block until next spring.
This idea will appeal not only to children, but also to adults, since the finished onion will have a sufficiently high destructive power. Personally, as a lover of medieval themes, I was very glad to have the opportunity to recreate such a striking representative of it.
The main elements of the product:
Implementation process:
This simple yet incredible useful thing household items has many options for the material in question. Depending on your imagination and what you want to get in the final form, you can assemble either such a complex structure as in the photo, or a floor structure with a stand, but I will describe to you the simplest and easiest option that I used myself:
I will not indicate the dimensions, since using a similar technology you can make both a child's and an "adult" chair or stool. So it is better to remove the linear parameters from the usual purchased sample and be guided by them. I also note that in a similar way, you can build a table or even a small single bed.
The assembly instruction looks like this:
If we complicate the structure using a similar assembly technology, then, as I noted above, even a bed can be obtained:
Here is another incredibly simple and original method of using plastic pipes:
The same method turned out to be an excellent organizer for the bathroom, only here I no longer began to make oblique edges:
I would also like to note that using a similar technology, that is, by gluing tubes to each other with walls, you can create strikingly beautiful pieces of furniture interior in a modern original style, as shown in the following photo:
First thing here, I took care of the electrical part:
And I have not yet managed to make these products from polypropylene pipes with my own hands:
You can play LEGO even as an adult. Only instead of multi-colored cubes it is then worth using polypropylene pipes and fittings. This will not only satisfy your thirst for design, but also allow you to acquire interesting, original, functional, practical and inexpensive things that your loved ones will also appreciate. Use your imagination and get down to business!
This machine design is for those who want to quickly make small drilling machine, at the same time does not have the desire or ability to work with iron.
A drilling machine made of plastic pipes has a number of advantages compared to a machine made of iron:
