How to properly bend a polypropylene pipe at home and avoid deformation. Finishing walls with plastic PVC panels by gluing them Conditions under which it is possible to cover walls with plastic using glue
Polypropylene pipes are the most common material that is often used when installing a heating system. A polypropylene pipe can withstand high-temperature coolants and can withstand pressure of several atmospheres inside the pipeline.
Flaw PPR pipes The problem is that they are sold straight, and to create systems of complex configurations, a pipe with a certain bend is often needed, which has to be done manually.
However experienced craftsmen repairs often involve bending pipes, and this does not cause problems with deformation or loss of strength.
During construction complex system heating systems, it is necessary to create structures of complex configurations.
Let's say in apartment buildings, where each room has a separate riser and one radiator, the system is very simple. One pipe goes from the riser to the radiator, the second - back. Sometimes they are connected by a third. In this case, there is no point in bending. It is enough to supply the correct connecting elements in the amount of 4 - 6 pieces.
Things are different in a private house, where heating has to be installed from scratch, starting from the boiler and pipes taken out from basements upstairs, to all rooms. Sometimes it is difficult in this case to build a straight-line system that will be devoid of turns and changes in the height of laying pipes. You can install two various pipes, connected by a special coupling, but this is labor-intensive, costly and less effective.
Another large area of application for bent polypropylene pipes is the underfloor heating system. The fact is that the pipes in this case are laid according to a pre-planned pattern, reminiscent in shape of a tubular electric heater washing machine or “coil” in the bathroom.
It's been a while since I wrote here! And you can find a lot for this good reasons... AND main reason- I was engaged in what, as they say on the radio, is not the “format”! And so, not according to my desire, but out of necessity, I started renovating the bathroom. Previously, the renovation was done in 2005, this date is solely for the purpose of understanding what was available then from available technologies and materials. I think that some ideas are still relevant today! For this reason, I decided to post several articles, so to speak, in reverse order, i.e. during the analysis...
This first article is devoted to the issue of bending of plastic panels when covering rooms in corners. I think that this question may be well known to many, but there will also be those who simply did not think about this option for resolving the issue, but followed exclusively the path that our industry offers and bought various corners provided for these purposes. In my opinion, the option I proposed, firstly, will save money (not buying corners), secondly, it looks more aesthetically pleasing, and thirdly, it allows you to maintain the integrity of the structure. Maybe someone else will come up with an idea positive traits, I think these are quite enough!
So, let's take a look at it plastic panel! (for demonstration I used scraps, debris - in short, garbage)
For creating internal corner It’s enough just to make a cut along the entire length of the panel from the “wrong side” of the required segment, which will subsequently form the angle. The cut can be made with a simple construction knife. The panel is cut quite easily and simply.
As practice has shown, although a simple cut is enough, it is still better to completely “select the material” from a given segment in pairs - as in the photo below. This is due to the fact that when bending, the edges of the cut plastic can interfere with each other... !!! not required, but recommended!!!
You need to bend it carefully, with smooth movements, gradually along the entire length, so that the panel does not break in this place. A fairly large angle can be achieved.
For external corner, you need to “select material”, no longer from one segment. This is due to the fact that the cut edges overlap and they begin to rest and prevent the panel from bending.
If you do everything correctly, slowly and carefully, you can achieve results like these!!!
INTERNAL CORNER
OUTSIDE CORNER
Attention, smooth and good angle, it will work out if the walls that you are sheathing/pasting with panels also have normal angles!!!
Many people wonder how to bend plastic PVC pipes on one's own. Indeed, in the process of installing heating and water supply systems, you very often have to deal with deformation of pipes, but many, not knowing how to do this, acquire a lot of unnecessary components, with the help of which they create bends and branches of the channel. At the same time, they spend almost a third of the allocated budget for creating the entire pipeline. More rational and in an inexpensive way is bending PVC pipes.
So, in order to bend a polyvinyl chloride pipe intended for heating and drinking water supply systems, it is necessary to remember and put into practice several well-known methods of influencing plastic products using heated air and a vaporous substance. In addition, in independent construction work there is a way to bend PVC pipe using the included gas stove. So, let's talk about everything in more detail.
As for the handy method of bending plastic pipes, it consists in heating up exactly that section of the pipe that will bend. A home stove, or rather, one of its burners, can help in this matter. But when using this method of bending plastic pipes, you need to be vigilant and careful, because open flame can damage not only the pipe, but also human hands. And in more serious cases lead to disastrous results. Therefore, there is always an alternative to everything that happens, regarding methods of bending PVC pipes, including.
More in safe ways creating any bend and direction of the pipe intended for supplying water are:
1. You can bend a plastic pipe using a technical hair dryer. To ensure the proper shape of the PVC pipe when it is heated, so that it does not start the melting process, it is necessary to pour into its internal cavity a material that is resistant to elevated temperatures, and whose structure has the form of finely ground fractions. Such materials include both sand mass and salt mass. Using a construction watering can or funnel, it will not be possible to pour such materials inside a polyvinyl chloride pipe a lot of work. Naturally, one end will need to be sealed with a stopper or barrier cap. Approximately, to fill a standard (length about 3 meters and diameter about 2 cm) plastic pipe intended for creating a heating system or water supply channel, you will need about one bucket of bulk material. Knowing all the calculations, you can purchase everything you need in advance and not worry about whether the available materials are enough or not.
2. Plastic pipe can be bent without the help of a technical hair dryer. This method involves heating bulk material (sand mass or salt mass) using oven. To realize your plan, you will need a baking sheet and a preheated oven. After the bulk mass has warmed up to desired temperature, using a scoop and a construction funnel, you need to pour it into the internal cavity of the plastic pipe. It must be taken into account that when choosing this method of bending a PVC pipe, you need to have a crow and a metal barrier cap.
An important nuance is to determine the required temperature, sufficient for bending plastic pipes, as well as polyvinyl chloride pipes, independently. In this case, you need to think logically. This question can be considered using an example water heating tank. So, the tank heats the water, according to the recommendations in the instructions for the product, to a maximum of 75 degrees Celsius, but it is advisable to adjust the mode and set the heating temperature to 60 degrees. This is necessary in order to avoid the formation of precipitation on the walls of the tank during heating at high temperatures. So, by analyzing the available data, we can conclude that the required heating temperature of the bulk mass must definitely be above 80 degrees. There is information on the Internet that such masses need to be heated to at least 140 degrees and no more than 170 degrees, so this extreme temperature is considered the melting point of plastic and PVC products.
All methods of bending PVC pipes for water supply systems have been considered, and you need to make a choice only based on your wishes.
What methods can be used to bend PVC pipes intended for sewer systems?
Few people know that such rigid PVC pipes with a large diameter can generally be bent. You need to understand that not all types of such pipes can be bent. Moreover, you can only bend the pipe a little, but that's already something. In most cases, as practice shows, plastic pipe for sewerage, having a diameter of 1011 cm, can be bent by a maximum of 25% using a technical hair dryer. Do not worry if relief formations in the form of folds appear on the outer surface of the PVC pipe after treatment with a technical hair dryer. Such formations do not impede the passage of masses through it, and also do not weaken the deformed areas.
Pipes made of polyvinyl chloride or plastic with a diameter of 56 cm can be easily created. For bending such products, a technical hair dryer is used or hot bulk materials technology is used. Before the process of creating bends, it is necessary to undergo a training exercise. There is no need to skimp on materials to hone your skills. Such training will help to achieve a good result at the end of the process of bending the desired plastic product.
The bending process itself sewer pipes made of plastic or polyvinyl chloride is not much different from the process of bending pipes for heating systems or water supply systems. Initially, it is necessary to heat the bulk material to 80-100 degrees Celsius, and then pour it into the cavity of the plastic product. Next, you need to wait some time for the PVC pipe to warm up at the intended bend. Once you have waited, you can begin to give it the desired look.
Today's construction technologies have reached the level of creating special bendable PVC pipes for sewerage systems. They are produced in different sizes and with different diameters. Therefore, when purchasing such a pipe, you can avoid imparting flexible properties to the pipe yourself. But the choice is always yours!
PVC pipes as raw material for manufacturing various crafts and homemade products are being used increasingly. Sometimes craftsmen give them an ornate curved shape and the final work after application finishing coating Even the finishing does not resemble the source material. In this master class we will demonstrate a similar technique to you.
Materials
To bend a PVC pipe you will need:
the pipe itself;
durable tape;
sand;
funnel;
metal container;
gas or electric stove;
protective gloves;
knife or scissors;
saw or hacksaw, as well as sandpaper.
In addition, you will need a pipe bending device. IN in this case a piece of plywood with dowels embedded in the thickness was used.
Step 1. Usually used for pipe bending gas-burner, but with its help you can give the pipe only a slight bend and only by small area.
It is difficult to process significant sections of such material in this way. This takes a lot of time, and besides, the pipes are often bent during work, which does not look aesthetically pleasing.
To bend a pipe, as you see in the photo of the final work, it requires uniform heating from the inside. For this difficult operation we use sand. So, first of all, you need to cut a piece of the required length from the PVC pipe and clean the edges of the cut.
Step 2. One end of the pipe must be sealed with tape. The tape should completely cover the hole.
Using a funnel, you need to pour sand into the pipe. Take enough of it so that the pipe is completely filled with it.
After measuring the required volume of sand, pour it into a metal bowl and warm it well. The sand should become hot.
Wear protective gloves on your hands. Using the same funnel, pour the prepared sand back into the pipe.
Cover the other end of the pipe with tape. This is necessary so that the sand does not spill out during work.
Leave the pipe like this for a couple of minutes. During this time, it will warm up from the inside. The material will become soft and pliable.
While the sand is still hot, you can give the cut piece of pipe the bend or shape you need. After this, remove the tape and pour the sand back.
Once completely cooled, the pipe will hold the shape you gave it.
