Welding machine for polypropylene pipes: classification, rating of the best + selection tips
To assemble a heating circuit or water system, you need a welding machine for polypropylene pipes - an indispensable equipment when laying a plastic pipeline. The tightness of the joining of parts will ensure a correctly selected unit.
In this article, we will deal with the main types of devices offered by the market. Find out their main characteristics and features of use.
We also highlight the main criteria that should be guided when choosing a suitable welding machine. Indeed, before buying a tool, it is important not only to evaluate the upcoming work front, but also to determine the appropriate model by comparing the parameters of the option you like with the available budget.

Fundamentals of the functioning of welding machines
In engineering networks of private housing construction, multi-apartment, industrial and public buildings polypropylene pipes surely displace metal. The demand for plastic highways is explained by their durability, affordable cost and resistance to external influences.
The current trend provoked a high demand for apparatus for welding polypropylene and polyethylene pipes professional and domestic purposes.
Mandatory elements of the welding machine:
- Adjustment unit. The module controls the heating power, protects against voltage surges and overheating.
- Lever. A component of manual modifications.
- Heating mirror. The element transfers heat to the working pipe and nozzles.
The operating mode of the welding machine is determined using a thermostat. The heating temperature is set in accordance with the pipe material. Exceeding the indicator leads to uncontrolled melting and the appearance of defects. Inadequate heating can cause a leak in the seam.
Classification of soldering irons for PP pipes
If you evaluate the range, then we can distinguish two main classes of apparatus for welding plastic pipes: mechanical and manual. The main separation parameter is productivity and scope. In addition, the units are classified by the method of welding on butt and socket devices. Features of the device and operation of each type are described below.
Powerful mechanical and electro-hydraulic devices
Mechanical and electro-hydraulic devices are used for joining pipes of large diameter (over 5 cm) or in conditions where the combination of joints requires a significant load.
The mechanical docking of pipes is carried out in a rigid case with semicircular moving centralizers. The ends of the products are aligned with an electric trimmer equipped with double-sided knives. Plastic warms up due to a powerful heater and pipes join - pressure is supplied manually through a lever. Clamping force is monitored by a built-in dynamometer.
A butt welding technique using the appropriate apparatus is recommended for connecting PP pipes whose diameter exceeds 63 cm. The permissible pipe thickness is at least 4 mm.
The coating of the clamps is made of metallized Teflon, which prevents the hot plastic from sticking to the working elements of the apparatus.
The connection of parts with an electro-hydraulic apparatus for soldering polypropylene pipes is carried out by analogy with a mechanical device. The difference is in the method of creating pressure. The clamp is carried out by an electro-hydraulic drive.
Some electro-hydraulic units allow welding of T-shaped plastic structures.
These devices are of high cost and are not intended for soldering pipes of small cross-section. Therefore, the main scope of their application is industrial enterprises and utilities. The use of mechanical and electro-hydraulic devices in everyday life is unprofitable.
Xiphoid and Cylindrical Hand Models
A manual type welding machine is often referred to as a “soldering iron” or “iron”. The compact device is suitable for home and industrial use. The maximum diameter of the joined pipes is 125 mm.
Based on the shape of the heating platform, two types of "soldering irons" are distinguished:
- xiphoid;
- cylindrical.
The forms of welding machines and fixed to them popular names: the first option looks like an iron, and the second - an ordinary soldering iron. The platform configuration does not affect the principle, operating procedure and quality of the device. The differences are in different types of nozzles and how to attach them.
For soldering individual heating, two or three sets of nozzles are enough. Models designed for the use of more than 3 diameters belong to the category of professional equipment and cost from 250 cu
A pair of separate nozzles is installed on the “iron”:
- sleeve - heating of the outer surface;
- mandrel - heating and melting the inside of the fitting.
Both nozzles are fixed with a long screw, which is tightened with a hex wrench.
Less popular are the xiphoid varieties with a shortened heater. Model No. 1 (photo below) is highly specialized and designed for the installation of large mandrels and couplings, the power of the heating element allows you to solder large-section PP pipes.
Detailed recommendations on the selection of the iron and its use are given in this article.
Devices with a cylindrical heating rod are equipped with nozzles according to the type of split clamp.
Experts highlight a number of advantages of “soldering irons” over “irons”:
- the master independently selects the nozzle location area - there are no specified holes;
- the ability to choose the angle of the pipe relative to the horizontal plane - relevant when soldering complex components at the installation site of the pipeline;
- increasing work efficiency by increasing the contact area of the heater and nozzles - heating is accelerated;
- there is no need to periodically tighten the fixing bolts to prevent axial displacement of the nozzles during welding.
Cylindrical devices are compact, stable heating temperature and high cost relative to the xiphoid models.
We talked in more detail about the choice of a device for welding a “soldering iron” type in next article.
Butt and socket welding machines
Soldering is carried out in two technological ways: butt and coupling. Accordingly, all welding machines can be classified according to this criterion.
How is butt welding performed?
The technology is applicable for pipes of equal diameter with a plastic thickness of 4 mm or more. The main requirements for high-quality adhesion: a clear alignment of the connecting elements and careful trimming, ensuring a tight fit surfaces.
Butt welding machines operate according to the following principle:
- Trimming and processing of pipe ends.
- Simultaneous heating with a disc heating element.
- Compression of mating parts - pressure is applied strictly along the axis of the pipe.
- The achievement of the diffusion effect is the penetration of molten polymers into the structure of adjacent parts.
After a technological pause, a cooling and final polymerization step follows.
Features of coupling soldering
The fulfillment of the condition for alignment of parts is achieved due to the selected sizes of nozzles and pipes.The unit simultaneously heats the inner walls of the coupling (tee, fitting or adapter) and the outside of the pipe to the same length.
Heated parts are applied and joined together with each other manually. The ratio of the diameters of the mating elements provides the necessary compression force - for interpenetration and polymerization, it is enough to hold the parts together for some time.
During the connection of polypropylene pipes using a welding machine, a number of standard actions are performed. As a result of the diffuse connection of the plastic components, a durable airtight pipeline is obtained, capable of working reliably for decades under standard load. Here are the steps of the procedure:
Evaluation of the parameters of manual soldering irons for pipes
Given the demand of consumers specifically for the model of “irons” and “soldering irons”, it is worth separately considering the criteria for choosing household welding machines. First of all, productivity, temperature indicators, quality and quantity of the offered nozzles are taken into account. An important factor is pricing and assembly quality.
Power and heating temperature
Power determines the operational potential of the unit. The higher the indicator, the wider the possible diameter range of the welded pipes. In addition, the heating time depends on the performance of the soldering iron, and accordingly, the speed of advancement of welding work.
However, for home use, buying high-power equipment is impractical for a number of reasons:
- The quality of soldering does not depend on power characteristics.
- Temporary superiority for heating is relevant for pipeline assembly of the pipeline. In everyday life, the difference is not particularly noticeable - while the soldering iron heats up, preliminary marking, fitting and docking is performed.
- More powerful devices consume more electricity.
For the correct calculation of the power of the "soldering iron", the estimated diameter of the pipes is taken into account.
Equipment for 1.2 kW is suitable for domestic needs - this is quite enough for laying a home heat or water main.
The quality of the weld depends on the stability of the temperature effect. Most devices produce 50-300 ° C of heating, the standard operating temperature is 260 ° C. More about polypropylene soldering temperature we wrote here.
The presence of a thermostat is especially important for beginners. An experienced specialist works on sensations - he determines the duration of heating intuitively without a sound signal.
Amators of welding craftsmanship should rely solely on standards and choose a model with continuously adjustable temperature. The position of the flywheel must be stable and not shifted by accidental contact.
High-tech models have a digital temperature display panel. The presence of the option is convenient for the user, but entails a significant increase in the cost of the device.
Options and usability
The “filling” of the welding kit affects the price of the equipment. The choice of this or that set is carried out proceeding from their individual need.
As a rule, manufacturers offer three types of standard kits:
- Economy It contains directly the welding machine, adjusting key and user manual. Sometimes complemented by one or two nozzles. But to choose a pipe cutter and other necessary tools to be done separately.
- Base. In the set, in addition to the device, instructions and key, the most common nozzles for household use with a cross section of 20-40 mm are provided. All components are packed in a convenient, bulky suitcase.
- Full. In addition to the soldering iron, the mandrel and the couplings, all the accessories necessary for soldering are assembled: a screwdriver, stand, screws, an allen key, scissors for PP pipes, a tape measure and mittens.
Some manufacturers complete the kit with a small bubble level to align the pipe line.
To ensure convenient use, it is important to consider some nuances:
- a tripod or soldering iron stand should not be very light, the best option is a stable platform;
- the device with clamps is suitable for work on a workbench;
- the handle should not heat up and slip in the hand.
High-quality welding units are equipped with an alarm system that disconnects the device from power supply at the risk of overheating.
Value for money
Equipment with the same technical parameters varies from manufacturer to manufacturer. The price is determined by the reputation of the brand, type of apparatus and equipment.
The leaders in this market segment are foreign companies: Rothenberg, Dytron, Brima, Kern and Candan. Among domestic manufacturers, the demand is for goods "Enkor", "Energomash", "Caliber".
Among experts, there is an unspoken rating of countries manufacturing welding devices for plastic pipes.
The championship rightfully belongs to the European brands Rothenberg (Germany) and Dytron (Czech Republic).
Despite the high cost, European products hold the lead in sales due to reliability, durability, unpretentiousness and ease of use. The equipment is characterized by light weight, compactness, mechanical endurance, long service life and a variety of model range.
A worthy alternative to Czech and German devices is Turkish-made hand-held soldering irons. Well established: Candan, Cobra and Valtec.
The most affordable price niche is occupied by Chinese and Russian units. The cost of cheap models starts from 15-20 cu The quality of performance is often “lame”, thermostats differ in their inconsistency - the spread of readings reaches 10 °.Such an error is fraught with depressurization of the soldered elements.
However, among the Sino-Russian assembly there are competitive devices, for example, soldering irons "Energomash", Wester and Sturm (German development made in China).
Next, we give the characteristics and features of the popular modifications of manual welding machines for joining a plastic pipeline.
