The design of the welding machine for PPR

A manual electric soldering iron (masters call it an “iron”), designed for soldering plastic pipes and fittings, consists of the following parts:

• housing with a transformer unit, thermostat and controls, equipped with a handle;
• a heating element with a power of 500 to 2 kW is installed in front of the case, depending on the model;
• stand and power cable connected to a conventional 220 volt outlet.

Using the regulator, you can set the heating temperature of the mandrel in the range of 0 ... 300 degrees

Heating of polypropylene parts is carried out using nozzles with a diameter of 16 ... 63 mm (household series), coated with a Teflon non-stick layer. The appearance and principle of operation of the device has a certain similarity with a conventional iron:

1. The user turns on the heating and sets the required temperature with the regulator, for polypropylene - 260 ° C.
2. When the platform with nozzles reaches a predetermined temperature threshold, the thermostat turns off the heating element.
3. In the process of soldering pipes, the surface of the “iron” begins to cool, so the automation again activates the heating.

Teflon-coated nozzles consist of 2 parts - a pipe is inserted into one, a fitting into the second

For welding parts from PP-R, a deviation from the established limit of no more than 5 degrees is allowed, polypropylene is heated to the melting threshold. Exceeding the temperature leads to a change in the structure of the material - the plastic "flows" and fills the flow area of ​​the pipe.

Insufficient heating gives a poor-quality connection, which loses its tightness after 3-12 months. How to properly weld a polypropylene joint, read in a separate material.

Typical soldering iron design

The design features of welding machines are similar to each other. The heating elements responsible for melting are located inside the case. There is also a holder, it is thermally insulated for safety, this allows you not to change the position of the tool during operation.

When welding large diameter propylene pipes, a complex device is used to control the process. The heating temperature is of great importance, because if it is violated, it is possible to melt the tube or coupling more than is required for soldering.

This is what a good soldering iron differs in, it does not allow such situations. The design is often equipped with a block responsible for the operating temperature of the heating device, as well as for the heating time of the elements.

When choosing a device, you should pay attention to the binding of the heating temperature not only to time, but also the wall thickness and diameter of the product should be taken into account.

PACE PS90 with stand

American universal soldering iron with stand that works with ST and MBT stations. Its power is 51 watts. It has a high heat dissipation, and the limited power eliminates the possibility of overheating of the tool after soldering. As a result, it is used when working with the most sensitive elements. This effect is available due to the special heat-conducting insulating materials of the winding structure. There is no barrier between heater and handpiece.

The advantages of the device are excellent thermal stability (with a strong heat sink, the set temperature is maintained). It is compatible with most PACE stations and requires no calibration. Convenient design of connection of the handle with the heater. Pleased with the anti-static coating of the handle.

Given the shape of the handle, it is not very comfortable in the hand (individually). After several uses, the device may work poorly (possibly a single defect). Other than that, it does its job perfectly.

Functionality

To solder polypropylene pipes, it is necessary to heat the ends of the pipes to the required temperature using a welding machine and connect them. The device comes with several nozzles of different diameters, which allows you to work with different sizes of pipes. To carry out high-quality soldering, it is necessary to know the exact temperature range.

The minimum set of welding equipment for the installation of propylene pipes consists of:

• heating elements;
• soles;
• nozzles.

The principle of operation resembles a home iron, only there are at least two heating elements in the soldering iron, and one in the iron. The thermostat is also different. The welding machine is equipped with a precise regulator.

Before proceeding directly to work, it is recommended to worry in advance and purchase the necessary additional tool:

• roulette;
• level;
• alcohol marker;
• cutter for cutting a propylene pipe.

How to choose a welding machine for polypropylene pipes

It is required to understand that there are certain requirements for choosing a particular model. Everyone should know exactly how they will use the device. Only then can you understand which soldering iron for plastic pipes is better to buy.

There are certain parameters that you need to pay attention to:

1. Temperature Range. It is optimal if the device supports from 50 to 300 degrees. If the temperature is lower, then this may not be enough. And if the lower threshold is higher, then there will be difficulties in working with pipes of small diameter.
2. Power. The minimum figure is 600 watts. Less powerful priors are not worth buying. But most professional devices have a power of up to 5 kW. Starting from 2 kW, there are semi-professional devices that are used quite often.
3. Additional security options available. They make the job easier and more convenient. And they allow you to be safe to a large extent. It is necessary that a stable and reliable support and a clear temperature regulator be included in the package.
4. Equipment. We are talking about the presence of matrices for working with pipes of various diameters. The more nozzles, the better.

When deciding which plastic pipe welding machine to choose, all the above factors must be taken into account. It is strongly recommended to buy a reliable unit from a well-known global manufacturer. This will allow you to work for a long time without the need to perform maintenance on the tool.Those devices that are listed in the rating of machines for welding polypropylene pipes are definitely distinguished by high reliability. They can be found in many specialized stores.

Piping material and types of connections

There are two ways to connect engineering networks: detachable and one-piece. Detachable include threaded flange and socket connections. One-piece - electrowelded and brazed. When installing copper internal systems for cold and hot water, soldering was indeed used. In some special-purpose buildings, this installation method is still used today.

Until recently, all this applied to metal water pipes: steel, non-ferrous, cast iron. Steel is subject to corrosion. This is a serious disadvantage for water networks. Stainless steel is expensive and is used only in industry. It is no coincidence that polypropylene and polyethylene water pipes have recently gained well-deserved popularity. Their use significantly reduces the cost of installation work, increases the service life of water supply systems. Refusal of electric welding improves the environmental component of installation and the quality of drinking water. The installation of light, cheap, durable, durable and harmless plumbing systems is carried out by joining into a socket, using special welding machines, popularly nicknamed "soldering iron".

How to use the machine for welding polypropylene pipes

The pipe connection process is fast. For example, soldering pipes with a diameter of 20 mm will take 5-7 seconds to warm up, 4 seconds to join, and 3 minutes to cool. In total it turns out 3 minutes 9 seconds. The main requirement that must be observed is to perform actions without delay, without creating a hitch.

Training

Before you start soldering pipes, you should prepare the connecting elements, consumables and tools. The list of required funds includes:

• polypropylene pipes;
• couplings, plugs, angles, tees;
• clips for attaching pipes to the wall;
• pipe cutter;
• shaver (facer) for stripping edges from reinforcement;
• measuring devices (tape measure, marker, level, etc.);
• gloves.

The main tool used for soldering can be rented if one-time work is performed. It is advisable to purchase a bell-shaped apparatus in cases of assembling the system from scratch and subsequent maintenance.

Marking and cutting pipes

Even before soldering, you need to cut the pipes into fragments corresponding to the drawn up scheme. It is easier to assemble the system when small sections of pipes are connected by fittings, forming separate nodes.

Pipe cutting is done with a pipe cutter. Fittings are selected according to their diameter. These include: tees, couplings, corners. When using reinforced products, it is necessary to first remove the aluminum layer with a trimmer.

It is easier to fix the connecting elements if the pipe sections are even. Therefore, cutting is performed strictly perpendicular to the axis of the pipeline. After cutting, the edges are cleaned and degreased with a special tool.

Connecting elements and heating

The soldering process begins with the preparation of assemblies and fittings, as well as the connection of the apparatus. The device should warm up to +260 degrees. This value is indicated in the device manual.

Further execution in the following order:

• make marks along the edges of the pipes that determine the depth of surface heating;
• check the condition of pipes and fittings, they must be dry and free of grease;
• insert the end of the pipe into the coupling to the basting, install the connecting element on the mandrel to the stop;
• warm up the parts in compliance with the time, quickly insert the pipe into the fitting (immediately you need to make a high-quality connection, amendments are not allowed);
• after joining the parts, you need to wait until the heated surface cools down (this takes an average of 3-4 minutes, depending on the diameter of the pipe);
• repeat the process with the rest of the nodes.

If the soldering technology is followed, a strong hermetic connection is formed. The system is an integral line, ready for operation.
