Cutting plastic sewer pipes tool. Nuances during work

How to choose and use a pipeline for plastic pipes

The quality of the installation of the pipeline from polymer materials directly depends on the characteristics of the pipe cut. A special pipeline for plastic pipes allows you to quickly, without unnecessary efforts and operations, and cut the material with qualitatively into segments. The shelves of construction stores offer professional equipment, which differs in price, design, material. For a choice, it is important to pay attention to the material from which the pipes are made, and choose a tool that is suitable specifically for working with this material.

Types of plastic pipes

In household communications, all types of polymer and combined tube materials that the modern market offers. Their purpose is limited by the technical characteristics of materials. Depending on what conditions (temperature, pressure, location) the system will be operated, the material is selected.

Metalloplastics

Metal.plastic is multifunctional pipes, used to build a water supply, heating, installation of a warm floor. They have a multilayer structure (5 layers) and are combined. The middle (3rd) layer is aluminum foil, which is firmly fastened with an adhesive base with polymer.

Installation of metal.plastic pipes is carried out using metal fittings. The requirements for the cut are strict, since the quality and durability of the connection depends on this.

Polypropylene

Polypropylene materials are widely used to install water supply networks. These plastic pipes are collected using special fittings and diffusion welding. The capacity of the future water supply, the number of fittings, service life directly depends on the quality of the cut of the polypropylene pipe.

Cutting polypropylene pipes with improvised devices leads to microcracks of the pipe itself. This is especially critical if the pipeline is planned to be carried out in a closed way.

Polyethylene

There are two types of polyethylene pipes. high and low pressure. Polyethylene materials of high pressure (PVD) are used for the construction of non.storage communications, such as sewage, sanitation, channels for laying electrical wires.

PND. low pressure polyethylene is a material for the construction of pressure taps and gas networks. Installation of polyethylene pipelines is carried out on fittings and welding. The requirements for the quality of the cut are high, and the material can be called supple for cutting.

Polyvinyl chloride

Polyvinyl chloride pipes (PVC) is a reliable material for the installation of industrial and household communications that are operated without heating. PVC is a rigid material that withstands significant external pressure. The main areas of application are water, sewer, electrical networks and the construction of artesian wells.

note! Polymer materials when cutting an electrician or corner grinder can not only be mechanically damaged, but also deformed from overheating.

How to cut a plastic pipe in an inaccessible place

It often happens that the PVC sewage pipe was carried out close to the wall or even laid in the recess. To get to it to cut it off with a special tool, it is not possible. So then do? But there can be many such examples and not only with a sewer pipe, but also with polypropylene pipes of large or small diameter, which are also located in hard.to.reach places.There is a rather simple way out of such situations.

Cut the pipe in an inaccessible place

Everything is banal simple. We will open from the coil about a meter of thread, it is not necessary to cut off. You can just hold in your hand. We start a thread for the pipe.

If there are gloves, then it is better to put them on. We pull the thread with both hands at the place where you need to make a cut. And we begin to drive the thread pulling one hand to you, then the other.

The pipe must be securely fixed so as not to tear it out. If not, ask someone to hold it while you saw.In a minute or two pipes will be cut.

It is quite simple, but it requires dexterity. Cases are not rare when the thread is torn during cutting. It doesn’t matter, take another and continue.

How to cut off exactly plastic pipe)

The topic, of course, is not worthy of the “do yourself” community, but it may come in handy)).

I am fighting in a private house with a septic tank and sewage. Need to cut plastic pipes a lot and evenly). And the idea came to me how to do it quickly and really evenly.

We take a trumpet of pipe with a flat factory ending. 10-15 centimeters will be ideal. And cut it along the corner grinder.

We put on the pipe, press with your hand, draw a fishing line for a trimmer cut with the second hand, then slightly shift and finish the gap where there was a gap.

Do not disdain headphones and glasses) there are different plastics and under the circle of corner grinders they behave differently. It happens disgustingly flying away in the eyes.

Slowly turning the pipe, cut off the corner grinder. As a rule, with a hacksaw, it does not come out smoothly)

Then we make a chamfer or manually or on a grinder. On the grinder, the main thing is to twist the pipe without stopping, then it will be even.

Everything has long been invented, especially for plastic pipes. Truborez.com/ here I chose when the construction was.

Grandfathers used sandpaper for this

triangular knock solves the problem of all pipes)))

made a mark by applying a rag sheet of paper.But this is invented great

I dressed clamps for these pipes and noted. But this option is better

Normul. You can use the A4 sheet you wrap the pipe, “make ends meet” and mark with a felt.tip pen (so you can cut any pipes up to 100mm) but this option is easier.

No, good idea! Thanks take a note

It’s easier to buy a cut.out circle with a table, there is now more than now.

you can take a tape measure or a regular sheet of paper. (from a notebook for example) wrap their pipe for them. combine the edges and get the same. Only universal. You can mark any diameters.

The topic is how to mark it smoothly, and not how to cut off evenly.it is through a knock or ended

Sorcerer is a disease))) By the way, a particle of “then” is written through a hyphen))) the same disease practically)))

And why through “o”, not through “a” ? Explain to everyone, otherwise you know in one.))

If you need to bridge, eat a double clutch

By the way, than to cut exactly along the pipe? except for corner grinding mashi without options?

probably still a corner grinder faster and more even

100% by the way cut along the pipe can be expanded into a plane and it does not break)))

I used to cut it with sandpaper with even edges, wrap it and circle

Any sheet of paper, folded from edge to edge and will be perfect. But cut off so only for a long and neatly playing with a canvas on metal.

The paper should be dense and so as not to crumble. And you can cut off even on a pendulum saw crooked

The main desire I was the last time a jigsaw, which I did not cut in life exactly, made a box. I tried so hard that the joints were like after a special. Circular. Slowly, accurately and will come out. Of course, it will not come out in life right in my hands.

In life, when marking the pipe, for installing UZ consumeriers, they used a diagram tape, well, or any other that turned out to be at hand, a newspaper, for example.

It seems to me it is easier to knit from three planks in 5 minutes, and then one hell to get what you cut

It seems to me it is easier to knit from three planks in 5 minutes, and then one hell to get what you cut

A wort in beer and kvass, and you need to make a knock.)))

Yes, you can just beer 🙂 I forgot already as a name, I did the repair for a long time 🙂 I will correct

We saw 110 pipes with an electric hacksaw with a short sheath for metal. 50 Cut Ridit with a cutter.

Lifehack: Zausenians from the inside remove with a drill by 10 for example, so that you do not buy a bastard.

A lot when you cut at all not to steam what is exactly, all the same through the cuff pipe into the pipe. Silicon to help

My comrade sharpened on a turning))) pressed in reverse fists in the cartridge, thought it was exactly, from behind, of course I did not press the center, and started it, I don’t remember what revolutions, but the decent were decent.This is what I’m doing, no one could have imagined that the meter plastic fan pipe flies at 5 meters, causing damage to all a number of standing equipment)

And scissors for cutting plastic pipes? Not? Cheap and angrily.

what scissors are you need for such a pipe? Yes, and they probably are not 5 kopecks. And there are no additional costs, it is one thing to cut metal.plastic, but not for Canal.

Three years ago I bought universal scissors for cutting plastic and metal.plastic pipes with a diameter of up to 75mm. something for 300, or so. For cutting pipes of larger diameter, he made a pipeline from various metallic trash. Cheap, evenly cuts, convenient and safe.

How to make a penny pipeline from a PVC pipe and for PVC pipes

So that the cut sewer pipe can enter the bell, you need to remove the chamfer on it. As a result, the preparation of each pruning takes time. If you make a pipeline of this design, then each wrapping will immediately have a shot chamfer.

The process of manufacturing a pipeline

On the bell, it is necessary to cut a 4 petal 20 mm wide with the same removal from each other. They should go from the beginning of the bend to narrow the bell into the diameter of the pipe. It is convenient to make holes on the boundaries of marking and cut everything with a jigsaw to them.

Next, you need to cut the step at the entrance to the bell, and remove the sealing gum. The petals must be warmed with a burner and bend it inside the bell.

A triangular cutter is pulled out of the bat. It is impressed into the hole in the clamp the tip inside. So that the plastic does not split, it is better to do in a vice, and not knock with a hammer.

To cut the pipe, you need to put on a bell limiter on it. Next, the clamp is pulled and aligned with a cutting cutter for cutting.

The clamp rotates on the pipe by the handle, while the cutter practically does not pass through the wall. At the end, you need to cut the pipe with a mounting knife. As a result, the cut piece and the rest of the pipe will have a neat chamfer, so they can easily enter the bells.

How to cut sewer pipes

At the moment, I use the special pipelines of Ridgid. I have two pipelines. One for pipes with a diameter of 32 and 40 mm, the second for pipes with a diameter of 50 mm.

A cutter is built in the plastic body of the pipeline, which immediately removes the chamfer when cutting the pipe. Therefore, sewer pipes after cutting such a cut are easily inserted into each other even without lubrication.

I believe that every plumbing should have such a cutter.

Sewer pipes with a diameter of 100 mm and higher, I cut a corner grinding with a diamond disk in concrete. Such a disk cuts, not melts plastic. I also make a chamfer on the pipe.

How to cut polyethylene pipes

Pipes up to 50 mm diameter I cut Ridgid cutters. As I said earlier, these pipelines remove the chamfer, and then the pipe is perfectly inserted into compression fitting.

Large diameter polyethylene pipes I cut with a saber’s saw with a large tooth. There are cutters for plastic pipes with a diameter of 100 mm and higher, but such cutters cost from 50,000. Therefore, plastic pipes, with a diameter of more than 50 mm, I cut it with a saber’s saw, and remove the chamfers with a knife.

Tips for choosing

Before choosing and purchasing such a device, you need to ensure that the quality is fully consistent with the proposed price.

If you plan to use a device for small plumbing repair work, then buying expensive scissors is not appropriate. However, do not forget that the cheapest scissors options are very low.quality. Often their blades are not covered with a special substance, and they also do not have sufficient sharpness.

If you opted for an automatic device, then you need to make sure that the scissors can easily cope with the pipes of large diameter.

The so.called precision scissors have always been famous for their versatility and low price. Such devices have always been reliable and quite convenient during use.

The price of scissors for carvings of the PP tube depends on the size of their diameter. The overwhelming number of devices are designed to use the physical strength of the employee. When performing large volumes of work, chronic fatigue may appear.

If the device is intended for serial repair work, it is advisable to use automatic pipelines. The guillotine option is designed for large diameter pipes.

However, not all buyers know the varieties of cut pipes. Below we consider them more details.

• The pipes that are used to create a warm floor, as well as for cold water systems, are indicated by the “PN 10” mark. The maximum temperature that can withstand these pipes is 45 degrees.
• Pipes designed to bring cold water to the building, PN 16 are noted. Such details create wiring that easily cope with high pressure.
• Products intended for both cold and hot water are indicated by “PN 20”. The highest temperature that can be transferred to the pipes reaches 80 degrees.
• There are pipes equipped with aluminum foil, with the most tolerated temperature of 95 degrees. They are marked as “PN 25”. These products are used to create central heating and hot water supply systems.

However, in addition to pipes, on the market you can find a fairly large number of additional propylene parts. And there are also products of combined type. This option has a brass insert and is called “American”. Using such a part, you can make a transition from a plastic pipe to metal elements of the plumbing system.

Consider various products of different manufacturers.

Features of Kraftool scissors

Kraftool specializes in the manufacture of high.quality tools. These products will withstand heavy loads even after prolonged intensive use. An interesting difference of the company is that it creates a beautiful design for each tool manufactured.

A huge number of tools are produced in Germany, which additionally guarantees excellent quality and durability.

At the same time, scissors for plastic pipes from Kraftool can be used in the most extreme conditions, but they will be in good condition for a very long time after the purchase.

Advantages of HENCO products

HENCO activities are not limited only to tools. They produce metal.plastic pipes for a variety of spheres. And in this case, scissors are side.made goods, but this does not mean at all that they are poor.quality. This company knows all the features and nuances of the structure of pipes and materials from which these pipes are made.

If you choose between the non-assembler and this company, then it is recommended to stop the choice on it precisely. Scissors for plastic pipes from Henco easily compete in quality with the manufacturer Kraftool.

How to choose pipe cutting scissors

For home use or for use from time to time, usually take mechanical scissors for cutting pipes. The design is chosen at the same time, so that it is “cheap and reliable”. Most often they buy scissors with rattle. In principle, an acquitted choice. Beginner professionals work and. You just need to choose the right model.

In general, you can give the following recommendations for choosing the type of cutter for pipes. A thin.walled pipe without reinforcement from any material is cut by a pipe.normal or scissors, regardless of the structure. Diameter restrictions-32 mm, wall thickness-up to 4-5 mm. Any pipes, what are? Yes, all: metal.plastic (MP), polyethylene (Pert, PEX), polyvinyl chloride (PVC), PVDF, low.pressure polyethylene (PND), polypropylene (PP, PPR or PPR), including reinforced with fiberglass and even small pipes (with a diameter of 16.20 mm) reinforced with aluminum foil. For the same pipes, but with a diameter of 4 mm or more, we need more powerful scissors. They should be more in size, and “tougher” in assembly.

Which scissors are better for PVC, PPR, PET, MP pipes

For reinforced polypropylene and PEX with a diameter of 25-40 mm, a good roller cutter is required, and for even more, a guillotine or the same roller scissors, but from a professional series are already needed.

Technical specifications

There are no difficulties in this paragraph. Two positions must be monitored:

Look carefully at these characteristics. It is a shame: you buy scissors for polypropylene pipes for a couple of thousand, and then it turns out that it is precisely polypropylene that they do not cut.

First of all, we look at whether the type of material we need, then pay attention to the diameters

Another such advice. It is better to take a cutter that can cut the pipe to the size of a larger diameter than you plan to mount. For example, you will cut a 32 mm pipe as much as possible, but take a tool for 40 mm. Why? A pipe of maximum size is very difficult. Namely, they usually do the main wiring. Smaller diameter only goes on layering. A tool for larger diameter in size is slightly larger (and a little more expensive), but it cuts easier.

By the way, a cheap tool has a pipe declared the largest diameter, sometimes simply does not fit into the holder. So you need to check. If there is no piece with you, compare the dimensions of the cutting part with similar. The dimensions are more or less the same? Excellent. If you have chosen in appearance less, it is better to postpone.

Frame

The case of the scissors can be made of silumin or other such alloy and steel. Inexpensive models from silumin can break if you are very crushing when you cut a large diameter pipe. So if you take silumin, so those that are thoroughly thorough and weigh not one hundred grams. We inspect the case for cracks, caverns, burrs. there are such damage. They immediately put them aside. Next, we examine on the following signs:

• Need a strong powerful case.
• Lack of backlash. If the new scissors hang out, then the cut will not be even. And if you also work with them, you will have to hold everything with your hands for sure.

We examine the handles. The main thing is that they are convenient. We’ll have to squeeze them, so the sharp edges, inconveniently lying in the hand, too, we put off. The best option is rubberized or with rubber lining. But this is already a non.budget series.

What can be the blade

The main working part of the pipe cutting scissors is the blade. It can be made of instrumental (cheaper and soft type of steel) and alloy (more expensive and durable) steel. As a rule, a blade of alloy steel can cut plastic and copper pipes. Scissors for polypropylene pipes have a instrumental steel blade.

The type of steel is not all. We must look at the thickness of the blade. If it is thin, with a large diameter, the cut goes to the side and cuts the pipe at an angle. But we need it under 90 °.

Carzac mechanism for pipes type “Pistol”

Why cut it strictly at right angles? To make the connection strong and durable. This is important for pipes of any type, but critically important for metal.plastic and polypropylene, reinforced with foil.

The thicker the blade, the easier it is to work. By the way, there are models of scissors for polypropylene pipes with a removable blade, there are those in which the blade and the “ladder” of the ratchet mechanism. one whole. The second option is more durable. The fewer the connections, the longer the service life.

What else can you cut pipes

Sometimes you just need to make a pair of cuts on the pipe. Buying for such a case even inexpensive scissors for cutting pipes does not make sense. This is what else you can cut off plastic, metal.plastic and polypropylene pipes:

• Corner grinder with thin (1 mm) disk. The pipe is clamped in a vice. Conveniently cut off 1-2 mm. This is necessary when fitting. None of the cutters or scissors, such a small piece is not able to cut off.
• Miter saw. Cuts perfectly. If there is, you can work for her.

After working with this tool, you usually need to correct the cut. If there are burrs, remove them, pour the shavings. In general, the cut should be even, and the pipe is clean.

Scissors Rothenberger Rocut TC 75 Professional

This model of scissors for plastic pipes is one of the best. It is suitable for cutting blanks with a diameter up to seventy.five millimeters. The manufacturer of the tool is the German company Rothenberger. If you need high.quality scissors for long.term use, this model of scissors will be a good choice.

The instrument blades are made of hardened steel Solingen. They produce direct raus of all types of plastic pipes. The tip of the blade has a V-shaped section. Due to the presence of a wide support for the workpiece, cutting at right angles is very accurate. In this case, there is no deformation of the cut product.

The design of the case of the scissors is durable. The material of manufacture is aluminum. Unlike other models for cutting blanks, some physical efforts are required. The design has a button for opening scissors. Capture the tool is convenient, thanks to the rubberized handle.

The operation of the scissors is convenient and durable. German quality speaks for itself. Perhaps the only disadvantage of this model is the high price. But if you want to use a really reliable and comfortable tool, we recommend that you purchase this scissors model.

Guillotine Rothenberger Rocut XL 125

The cutter is made by the same manufacturer as the previous model. Suitable for use in any part of the pipeline. The blade has a V-shaped shape that facilitates the process of cutting blanks. It is made of alloy steel. The angle of the cutting edge is optimized, which makes the use of the tool even easier.

The device of the lower clamp of the guillotine cutter is convenient. It is completely folded. Therefore, this pipeline can be used even in constrained trench conditions. The model is suitable for cutting pipes with a diameter up to one hundred and twenty.five millimeters. Can be used to work with blanks from all types of plastic.

The tool has proven itself well. Among models of a similar type, it is favorably universality and ease of operation. The replacement of the blades is carried out quickly and quickly. If you decide to opt for a rezak of a guillotine type, this option will be the most optimal.

What tool and how it is not recommended to cut polypropylene pipes?

Of course, in addition to the above specialized tools, polypropylene pipes can be cut by others and, which most often are in any home workshop. this is a hacksaw for metal or wood, an electric jigsaw or an angular grinding machine. “angular grinder”.

It is not recommended to cut the pipes with a hacksaw for metal or wood

However, it must be borne in mind that as a result of the influence of such tools on the pipe, the cuts will often turn out to be torn, with numerous burrs, or with melted ends, and this is unacceptable for the subsequent welding.

Therefore, before welding, it will be necessary to align and clean the ends of the pipes from damage and irregularities, otherwise the compounds can be inadequate as strong. And such cutting pipes often leads to problems already during the operation of the pipeline line.

• “Corner grinder” cannot be used due to too high rotation speeds-the plastic pipe will heat up and begin to melt. The same thing can happen when using an electric jigsaw, if it is included in the high frequency of file frictions. And at low speed. the cut is torn, microcracks can form along the edges
• Whatever the tool is used for cutting pipes, it is impossible to put pressure on the polypropylene walls. this applies to both improvised and special devices. Excessive application of force can lead to cracking the edge of the product or to the junction of the material. Such damage can in the future lead to rupture of the pipeline in the area of ​​connecting units.
• It is impossible to use a circular or strip saw for cutting polypropylene, since the material is quite fragile, therefore, without damage in the form of cracks and chips, it will not do in any way. In addition, with such an effect, the pipe can simply be pulled out of the hands.
• It is also not recommended for cutting PP to use pipelines intended exclusively for cutting metal products, since they often start not to cut, but literally tear plastic. Exceptions from the rules are universal pipelines that can be used for any material.

Brief review of pipeline models

As mentioned above, the pipeline model is selected based on its technical characteristics and purpose. The table offered the table presents several options for hand.made pipelines of different price categories.

That’s all. We hope that having figured out the question of what the pipes are cutting devices that the reader who received this information will be able to decide on the choice of the optimal pipeline model, taking into account his needs and capabilities.

In conclusion. an entertaining video about one interesting model of the Ridgid pipelines.
