A special soldering iron is used to weld polypropylene pipes. The device has a compact size, operates on a household power supply, and allows you to independently install water supply and heating systems.
Principle of operation: nozzles are fixed on the working element (mandrel) for heating the outer and inner surfaces of the connected elements. After reflow, docking is performed. The hardened material forms one-piece tight connection.

How to choose a soldering iron for polypropylene pipes
It is necessary to determine how often and what pipe diameters must be welded. The cost of the device and the efficiency of working with it depend on the correct choice of characteristics.
- pipe diameter determines the required set of matrices, which are usually available in the tool case; for domestic use, nozzles with a diameter of 20, 25, 32, less often 40 mm are needed;
- device power determines the heating rate; for household work, there is enough power up to 1000 W, this will save on purchase and energy consumption; the power of professional devices is 1500-2000 W, they have two separately switched heating elements; the price of the instrument is higher;
- stand used for stable attachment and ease of use.
Varieties of devices
Cylindrical soldering irons have a cylinder-shaped mandrel. The attachments are fastened using clamps. The design is very convenient for working in hard-to-reach places. It is possible to simultaneously attach up to 4 attachments to the cylinder.
Xiphoid appliances have a flat, sword-shaped heater. The attachments are bolted on both sides. The soldering iron is more suitable for working on the table when preparing assemblies. Up to 3 dies can be installed on the mandrel for simultaneous work with products of different diameters.
Additional functions and accessories:
- temperature control: the option allows you to accurately select the temperature so that the material does not overheat to a fluid state, and the joint does not lose its tightness due to insufficient heating. Some have a declared melting point of 220 ° C. Other products will have a 260 ° C mark.
- thermostat: the function is required to maintain the set temperature and save energy;
- pipe cutter: neatly and easily cuts the pipe to the required length;
- fixing clamps: serve to fix the elements to be welded;
- construction level - for accurate marking.
Which soldering iron is right for you
- For rare use, choose a Chinese or Russian-made tool with a flat mandrel for one nozzle, with a power of 800-1000 W; a set of nozzles 20, 25, 32 mm, a pipe cutter and a flat stand for working on a table;
- For permanent plumbing work, you will need an apparatus with a capacity of 1500 W produced in Turkey, Spain, Czech Republic, Italy-China, with the possibility of simultaneous fixing of 3-4 pairs of nozzles and temperature control;
- For professional use, an electronic adjustment function and a control display are required.
