If you started a repair, then you may need pipes. But not always in this case, they should be perfectly even. This raises the question of how to bend a pipe without a pipe bender. If you are familiar with the tricks of this process, then you can solve the problem quite simply.
How to bend a pipe at a right angle
Metal acts as a sufficiently strong material, but with a special impact it can be bent. To date, there are several ways to resolve this issue. The first technology is the use of pegs. But you must remember that this method can cause damage to the pipe or even its breakdown. This can be avoided by filling the internal cavity with dry sand. End caps should be installed at both ends.
The next step is to start bending. To do this, pegs are dug into the ground. You will use them as levers. If you are not confident in your abilities, then for a start you should practice on unnecessary pipe sections. If you have a question about how to bend a pipe without a pipe bender, then using this technology you can change the shape of the product, the diameter of which varies from 16 to 20 mm. For pipes of more impressive diameter, this technique is not suitable, since the process will be quite complicated. It is important to consider also the material that underlies. For example, other methods are recommended for galvanizing.
Using heating technology
Before bending a pipe without a pipe bender, you should think about which technology is best suited for this. Perhaps a great solution would be heating. This method is commonly used for steel and aluminum piping. For the procedure, the product is fixed in a vice, but first it should be filled and heated with a gas burner the place that you plan to bend. The temperature is determined quite simply: when a piece of paper approaches the pipe, it should begin to smoke. When a steel billet is used, it should turn red when heated. For safety, the master should wear gloves.
Plane parallel plate
If you have a problem how to bend a pipe without a pipe bender, you can use a plane-parallel plate. This technique involves fixing the product in a clamp. After this, you can bend, and you need to do this along the plate. This technique is considered not only economical, but also simple. In order to achieve a positive result, several plates should be used, each of which has a different curvature. The main condition is the use of a steel pipe. The length of the product should be quite impressive.
Using a metal spring
Quite often, home craftsmen think about the question of how to bend a pipe without a pipe bender at home. To do this, you can use a metal spring. This technique is excellent for non-ferrous metal pipes that have good ductility.
To prevent deformation, a spring is used. To get a good result, you should consider the size of the spring, which should correspond to the inner diameter of the metal structure. This requirement is due to the fact that the pipe has to be inserted into the cavity. After that, it is possible to carry out bending by tying the spring with a wire in order to simplify the process of its further extraction.
Wizard tip
If you need to bend a profile pipe without a pipe bender, water can be used as a filler instead of sand. The pipe cavity is filled, after which the product is plugged on both sides with plugs. Water should be frozen, and then heat the material. However, this method cannot be used for galvanized workpieces.
Profile pipe and its modification
This type of metal construction is quite popular in the construction of greenhouses and gazebos on a personal plot. The main feature of the building material is that when bent, it can be damaged. The way out of this situation may be to fill the inner cavity with fine sand or water. These actions eliminate the possibility of damage to the pipe and achieve excellent results. This technique is suitable for brass and duralumin piping.
If you are thinking about how to bend a pipe without a pipe bender for a canopy, then you can use a rubber mallet for this . It is used for square shaped products. The pipeline is installed on reliable supports, and then a mallet is used. Actions must be neat and smooth in order to eliminate the possibility of damage. If it is necessary to achieve a large angle, then to facilitate the process, it is necessary to heat the pipe in the place where it should be bent.
Metal-plastic bending methods
Quite often, owners of suburban real estate wonder about how to bend the pipe yourself without a pipe bender. When metal plastic is available, you can use your own forces without using improvised means. The product clamps and bends smoothly. In this case, it is important to exclude the possibility of an inflection. It is important to follow the rules that state that for every 2 cm of the workpiece, the bending angle can be 15 °.
If you have a question about how to bend a pipe without a pipe bender for a greenhouse, then you can use pieces of wire to fill the internal cavity. This allows you to achieve smooth and smooth bending in the shortest possible time. As a filler, you can use dry fine sand. He falls asleep inside, and the edges are closed with caps. Then one end of the product must be fixed, ensuring reliability and strength of fastening. Use a gas burner or blowtorch to heat the bend. Material is checked for readiness with a piece of paper.
Polypropylene pipe bending methods
If necessary, change the direction of bending of the polypropylene pipe, you can use one of two possible methods. The first involves heating the bend. A building hair dryer is usually used for this. The optimum heating temperature is 150 ° C. Hands should be protected with gloves that are resistant to high temperatures.
At the final stage, the product is bent to the desired shape. The thickened wall should be located on the outside of the bend. Once the material has cooled, it will need to be checked for cracks and dents. Another way to bend such a pipe is cold. However, the bending radius should not be more than 8 diameters, otherwise the product may break.
How to bend a plastic pipe
In order to bend the PVC pipe, you need to buy fiberboards. From them you can build a frame that will be needed to give the structure a certain shape. As soon as you give the plate the desired shape, you should sand it, it is better to use fine sandpaper for this.
The next step is to form a silicone sheath for the plastic blank. She will act as a fastening of the PVC structure in the frame. In addition, it will fulfill a protective role against chips, mechanical damage and scratches. The item is placed in a prepared protective shell, and after the bend is heated. The plastic softens and sits on the frame. Such actions will allow you to get the desired shape of the plastic blank. The product is left to cool. For this, 15 minutes will be enough. After the PVC pipe can be removed from the frame, leaving it to cool completely.
Specialist recommendations
If you were faced with the question of how to bend an aluminum pipe without a pipe bender, then you can use a grinder to carry out the work, with which you need to make several thin incisions in the place of the proposed bend. The product is pre-clamped in a vice. Once the cuts are completed, they should be cleaned of chips, only after which you can begin to bend the pipe.
Sometimes the product needs to be bent in a circle. As soon as the ring closes, the holes are welded, and some masters use a soldering iron for this. In order to make the fold place neat, it is additionally ground and coated with a protective agent. This eliminates corrosion and premature failure of the joint.
Conclusion
It does not matter which material underlies the pipe. Perfect bending is difficult to achieve. But if you first get acquainted with the theory, then you can bend the pipe even without a pipe bender.
