As plastic pipe bend how PVC pipe bend blower at home

When installing or repairing communications easily encounter difficulties in bending the pipeline. This maneuver can be carried out by means of special fittings, but excessive use of the fittings increases the risk of leakage. Instead, the element is bent in the right direction: it can be done with the help of the popular methods.

Properties of the plastic pipe

All plastic pipe can be divided by the material of their manufacture they are made of polymers, polyethylene, polyvinyl chloride. These materials have good health indicators, therefore, different everything for heating network, as well as for the organization of water supply in the apartment.

It does not always work on their own material to bend, so you have to use common methods

To bend their own plastic pipe need to learn more about its properties:

1. Ring stiffness. High rates of PVC hardness can withstand the atmospheric pressure of 120 atmospheres.
2. Resistance to heat. Plastic is resistant to heat, so it is used for plumbing arrangement with hot and cold water and for the organization of the pipeline with heating. When heating the plastic is lengthened only by 5%.
3. Low resistance to frost. Because of the low frost resistance, the materials can not withstand the temperature below -15 degrees, thus require additional insulation.
4. The high permeability of light. Painted in different colors PVC pipe is resistant to UV light.

When heating the plastic pipe can be accurately bent, because it has good elastic performance. Products made bendable in the manufacture of PVC may be initially wound into a ring - in this form they are commercially available.

Conditions for PVC pipe bend

Plastic bends perfectly if it affected certain temperature indicators. It is important to observe a number of conditions for bending:

• reheating portion to 75 degrees at the point where the bending will be performed;
• impact on the element by means of vaporous substances.

To avoid unnecessary weight fly fittings that require care during installation wizard often use different bending methods. When working with hot air which will affect the plastic, should be careful: you can not only fully burn spot heating, but also burn your hands. In this case, it is important to manipulate carefully and gradually.

It is difficult to achieve the ideal bend, so before you get started, it is advisable to carefully consider all future rotations of the pipeline. Pre-standing practice to bend the product on a small segment.

Basic methods of bending of PVC

Using the bending tool is necessary only in cases where the bend plastic pipe alone fails. This applies to products of large diameter, which are intended for arranging sewers.

Modern master successfully used by heating with a hair dryer, used sand, and a wire frame for establishing the necessary bends in the pipeline construction.

Using a hair dryer

The melting point of PVC starts at 140 degrees Celsius, but these figures may completely melt the element, preventing its integrity and basic characteristics. To avoid this, it is recommended to use a hair dryer building for the gradual heating of PVC products. Polypropylene tubes also are melted at high temperatures, therefore, they can be bent in a similar manner:

1. Creating a template for bending. Before you carry out procedures on liability, it is recommended to create a template for the bend: it is better to do of durable material. You can buy ready-made corners, using them to make turns.
2. Filling of bulk material. To stretch not melted, and adopted the correct form, the master advised to pre-fill it with salt or river sand. This can be done using a funnel: 3 meters of 20 mm diameter pipe required less than one bucket sand.
3. The heating portion hairdryer. To heat the material used technical rooms. First heating portion is selected, then the device is exposed to temperature and heating is carried out.
4. Bending articles. Once the item has warmed up to the point where he could easily bend - it is necessary to shift the pattern and carefully go around the shape.

It is important not to allow strong melting and heating to 170 degrees. In this case, the molten plastic and becomes unsuitable for further use. After cooling pipe is mounted on the template in its pipeline.

The use of sand for the bend pipe

When using sand will not be required to apply construction hairdryer. The technique consists in heating the salt or river sand in a pan. Heating takes place to the desired temperature by a scoop composition poured into the pipe. The whole procedure looks like this:

• heated sand via the bucket is poured into the plastic tube through a funnel;
• mounted on the back side metal plug to prevent any heat output;
• Minimal heating temperature sand or salt in the baking must not be less than 140 degrees and not more than 170 degrees.

When solids, warmed to the desired temperature, placed inside, it begins to affect the rigidity of the plastic. Gradually melts, so flexing takes place easily. It is also desirable to use a special template for bending to obtain a clean turn. If the result does not meet the requirements to use an element of security is impossible.

Bend plastic tube with wire

Bend lines by using the metal wire. In this case, the embodiment uses two D:

• applying wire pieces;
• application of a metal spring.

To bend the PVC tube for heating or plumbing in the home via the wire segments necessary to arm the metallic material along the length of the tube segment. Harvested pieces are inserted inside, completely filling the inner diameter thereof. If you do not close all the wire hole, will create unnecessary pressure, provoking the wrong bend. In this way, the material can be bent only when the support.

The use of a metal spring involves placing it inside the tube, so the spring diameter must match the diameter of the element. Before you bend your product with the help of the spring, it is necessary to attach the wire to the further extraction was easy.

Nuances bending pipes using eyeglasses

This procedure is performed in several stages. Bent pipes with the help of the frame, you must follow all the rules; to work better to buy or rent a molding machine. Stages of the procedure are as follows:

1. Making rims. Independently make the rim can be of hardboard. Such an arrangement is necessary to create the right shape bend.
2. Silicone shell. This adaptation is necessary to prevent scratches, defects and dents. To create a bend plastic pipe is better to use a molding machine.
3. bending procedure. The product is inserted into a silicone-based shell is secured in the frame of fiberboard. The construct was placed into a molding machine, in the place to bending is heated, the plastic begins to bend shaped rim.

Removing the pipe must be within 10 minutes. After it has cooled, it can be used for constructing the pipeline.

Typical mistakes when working

To plumbing or heating system did not allow failure, it is advisable not to make mistakes in the process of bending. Professionals always work according to pre-thought-out plan, but if a man makes a line for yourself, do not be amiss to carefully prepare for the creation of designs.

Common mistakes when trying to bend the plastic article:

1. Attempt to bend the material by heated air in several places: the material lends itself to bend only in the portion which is heated by means of the dryer construction.
2. Use gas burner with high melting temperature: in this case the material is simply melted and deformed.
3. To carry out bending of sewer pipes, not respecting the rules: sewer products not bend recommended, it is better to purchase a set of fittings and with the help of fasteners to install the desired angles turn.

It is important not to press hard on the pipe during cold-bending. To check the allowable angle should be multiplied value of pipe diameter to 8 - this is the maximum bending radius.

The list of tools needed to bend: masters recommendations

Manufacturers of polypropylene and PVC pipes strongly recommend yourself to bend the product at home. However, sometimes this procedure is necessary: ​​it should be reserved for special tools. To work required building dryer with good power and the ability to adjust the temperature. It will also need molding machine, if it was decided to stick to the material by the rim.

In the absence of a building dryer, it can be useful to a gas burner, but you need to work with it carefully, avoiding remelting of the pipe. If the element is bent with the help of a wire, it is necessary to prepare the Clippers cut it.

Several of the recommendations of professionals to help cope with the task:

• using technical dryer should be thoroughly warmed namely an upper part of the portion where the bending will be made;
• for the manufacture of the same bends better prepare homemade template;
• using sand, it should fill up to the full capacity of the lumen, but not much need to push the particulate material;
• for the stub is better to use metal products;
• flexion should occur slowly, from the jerks should be abandoned.

These methods bending PVC are the most trusted and frequently used by artists who do not have the tube bender. Correct, smooth turning of the pipeline to prevent the use of fittings, the investigator, the risk of leakage is minimized.
