The device for welding of pipes: versions and a scope

Recently, plastic pipes are gaining more and more popularity, since their service life and reliability are at a very high level, and the ease of installation makes it possible to significantly reduce the time of work. However, such materials require a special tool that is designed specifically for their use and meets the requirements for manufacturing to the maximum.

This particular product is an apparatus for welding polyethylene pipes, which, paired with a special soldering iron, can fully ensure not only the wiring in the room, but also the laying of entire tracks.

Soldering iron

To begin with, it is necessary to say that this joining process can be called both soldering and welding. However, it cannot be compared with the use of units that are used to work with metal systems. Therefore, usually the device itself is often called a soldering iron, and the process itself is called welding, although all this is rather arbitrary.

Tool

The device itself for soldering plastic pipes is a handheld device on which the heating element is located.

In this case, for its activation, an electric current is used, the power of which is regulated by a special handle that is responsible for heating.

• It is worth noting that there is simply a huge number of varieties of such devices, but experts recommend choosing only products from trusted manufacturers.. Particular attention should be paid to the number of seats under the nozzles. The fact is that during operation it is desirable to have several elements prepared with different diameters than to spend time heating another device.
• It is necessary to approach the choice of nozzles very responsibly.. It is advisable to have with you a full set of used diameters and at the same time stock up on additional replacement products. It is better to purchase similar elements with the presence of a special non-stick coating, for the convenience of work.

• It is important to mention that such a device for soldering pipes has a rather large cost, which means that it is easier to rent it for private work in order to save money.

Tip! Teflon coated tips are considered the best. However, they must be used very carefully in order not to damage it.

Soldering

• First of all, you need to pick up the nozzles of the required size and install them in the landing slots on the heating element.

• Then remove the soldering iron to the operating temperature. It is easiest to do this empirically, acquiring an additional coupling for connecting pipes.
• After the welding machine for PP pipe comes into operation, the nozzles are put on the elements that need to be connected. In this case, it is worthwhile to remove all the burrs left after trimming from their surface.

• Further, it is necessary to withstand a certain time, which is also chosen experimentally, in order for the parts to melt, but to keep the shape.
• Then all the elements are removed from the nozzles and connected to each other, holding to complete cooling. After that, the joint is considered ready.

Tip! Working with such a tool does not require certain skills, but it is better to spend a little time to select the necessary mode than to create a defect on the finishing structure.

Butt welding

When using products made of HDPE and other similar materials of large diameter, the method of butt-welding pipes is used. At the same time, it’s worthwhile to say that such installation systems are usually used only on trunk lines and pipelines with high carrying capacity. This helps to create a virtually solid connection, avoiding expensive couplings or other connecting elements.

Apparatus

At once it is necessary to say that this equipment is almost impossible to rent, and its cost is very high. It is acquired by brigades or services purposefully engaged in such installation. Therefore, it is much easier to hire such specialists than to acquire a tool with which you still need to learn how to work.

Typically, such an apparatus for welding PE pipes is made in the form of a kind of bed, which is worn on the edges of two ends that need to be joined. At the same time, its clamps securely clamp the material so that it does not move when soldering.

It should be noted that such units are equipped with special drives that create a certain pressure on the heating element and at the connection. They are mechanical, hydraulic or pneumatic. It all depends on the main power supply and control of the bed itself.

Special attention is given to the fact that such devices can also be used when working with systems of PVC and the like. However, the pipe must have a diameter of at least 50 mm, and the thickness of its walls is usually at least 5 mm.

Tip! The choice of the type of installation and drives depends only on the personal preferences of the master and the ability to perform periodic maintenance and repairs.

Welding

Doing this work with your own hands without some preparation is not worth doing. Such equipment requires the availability of relevant skills and knowledge of the temperature regimes of specific types of pipes.

Therefore, this installation is trusted only to specialists.

• First of all, both ends of the pipe are installed in the device and securely fixed to the pushers.
• Further, the installation manual recommends that you select the heating mode and lower the welding element between the elements.
• Then, with the help of pushers, the pipes are brought to the heating element, and they are kept until the ends start to melt. After that, the material is diluted for a small distance, but do not turn off the heat.
  

• After a certain time, the welding plate is removed, and the ends are joined with a help of pushers under a certain pressure.
• It is necessary to remove the device from the pipe only after the seam has completely cooled.
• It should be noted that there are such units that are equipped with special software that fully automates the entire process, selecting the necessary mode independently. However, the price of such equipment is quite high.

Tip! There are many models of such equipment and therefore, before making a choice, it is worthwhile to study the operating manual in detail and only then decide on the purchase.

Conclusion

After studying the video in this article, you can gain additional knowledge about such equipment and its use. At the same time, taking into account the article cited above, it is necessary to conclude that the units for such soldering and welding are quite expensive and sometimes it is much cheaper to rent them or invite specialists to produce these works.
