How to solder polypropylene pipes without soldering iron

How to solder polypropylene without a soldering iron

The soldering of polypropylene pipes today is acute for every owner of his apartment. All without exception want a high-quality pipe fastening, because this directly depends on:

• service life of a piped or heating system,
• need for repair costs.

Therefore, many are interested in how to properly weld pipes to avoid further trouble.

For soldering pipes made of polypropylene, of course, a special soldering iron is required. But what if there is no such tool in the house? The answer is simple: to use improvised materials and tools. For example, a gas burner.

Undoubtedly, there must be a gas burner in every house. But if it does not exist, when choosing this tool it is worth taking into account its main parameters:

• gas used;
• cylinder connection.

This soldering method is suitable not only for small diameter pipes, but also for soldering large diameter pipes.

With the help of a gas burner, it is possible to repair or install a heating system in a short time.

Soldering requires:

• of care,
• of care,
• of striving for quality,
• preparation for basic works.

Polypropylene pipe: soldering instruction

Let's consider step by step how to weld the pipes qualitatively:

Step 1. We select pipes of a suitable diameter. Please note: newly purchased pipes must match the old diameter. This will help avoid problems when connecting.

Step 2. After measuring, cut off the required piece of pipe. Do not forget to add an additional 25 millimeters, which will later remain in the fitting fused.

Step 3. We heat the pipe and fitting using a burner. You need to do this at the same time.

Step 4. After this, the parts must be connected and held a little, waiting for their cooling.

Please note: Before assembling the pipes, a detailed diagram must be drawn up to connect them. It is necessary to note the places of installation of turning corners, tees and cranes.

Recommendations for the successful operation of

Consider the tips and recommendations that will help to perform the work qualitatively:

• It is recommended to purchase the connecting parts and pipes of the primary one manufacturer. This is an important point, as each manufacturer has its own technology for manufacturing these elements. And this means that the melting point of the parts can be different, which is not suitable for monolithic construction.
• Before the main work, the parts must be cleaned and degreased, thus avoiding the quality of the connection.
• Practice first on the pieces of pipe to know what kind of effort you need to apply to get the expected result. Note: the pipe inserted into the fitting can not be turned in any case, this will break the joint strength, as the surfaces of the parts will gather in waves.
• If you choose quality, do not save! Good products will last longer, on which you will save in the future.
• If the room temperature is below + 5 ° C, do not take risks and start work, because its efficiency is significantly reduced. The connections in this case will be brittle, and the connecting parts will require additional heating. And this is fraught with unnecessary melting and deformation of the elements.

Soldering wires: how to solder, if there is no soldering iron?

For sure, many faced with the fact that you need to fix the two wires, but the soldering iron is not at hand. It remains to rely on the ingenuity of contemporaries offering easy ways of soldering, which everyone will master.

In the modern market such materials are offered:

• Solder paste;
• Tape is soldering.

Soldering without soldering iron with

paste A solder paste is a mechanical mixture of flux, solder powder and lubricant, that is, a binder.

Manufacturers of solder paste practice their manufacturing on the basis of silver, which makes it possible to use this mixture for soldering different types of nickel, steel, and also alloys from copper.

Requirements for

pastes Solder paste should:

• very quickly separate but do not oxidize;
• be viscous( which is very important!) And retain deformation;
• have adhesive properties;
• wash in normal solvents;
• does not drain out of the applied layer;
• do not leave any residues left behind after application;
• does not affect the technical properties of the board.

Steps for soldering the

Step 1. The primary task is to prepare the wires. We clean the surface of the wire by using a clerical knife or nippers.

Step 2. Wires are twisted.

Step 3. Place the spike carefully spread paste for soldering. Apply paste drops to the entire surface of the wire evenly.

Step 4. The place of application is reheated. You can use an ordinary lighter for this. After reheating, the paste will be a strong spike.

Step 5. Put the heat-shrinkable tube on the wire, which is also processed by the flame, so that it is evenly distributed over the wire surface.

Note: This method of soldering is suitable mainly for fastening small wiring, for example, wires from headphones.

Solder paste in water supply systems

Surprisingly, solder pastes are suitable for water supply. These substances have special requirements:

• Silver or copper is added to the composition of the solder, and this increases the melting point. This makes the alloy mechanically strong and durable.
• It is not allowed that the flux or solder has toxic substances in its composition, therefore they do not contain lead or any toxic metals.
• Flux should be easily flushed with water and do not cause corrosion.

Soldering with soldering tape

Soldering tape is a material that can be used for the installation of electrical wiring, repair or replacement, in domestic and field conditions, as well as in automotive applications.

Let's consider step by step the soldering process using a soldering tape:

Step 1. Remove the insulation from the wire, that is, clean it with wire cutters.

Step 2. Twist the wires, and after wrapping the twisting with a soldering tape. After removing the protective film, the side with the flux is applied to the wire surface and crimped.

Step 3. Heat the place of winding with a match or a cigarette lighter until the solder completely overflows the wiring.

Step 4. Wait for cooling, then remove excess flux.

As you can see, you do not have to buy a soldering iron to solder the wiring, you can use the methods described above. This will save both time and money.
