How to connect a polypropylene pipe with polypropylene without fittings? How to properly connect polypropylene pipes?

If there is a need for installation of plastic pipes, the so-called cold welding is most often used for this. This technology involves the use of special adhesive and fittings.

Advantages of using a pipe joint without hot soldering

If you are thinking about how to connect a polypropylene pipe to a polypropylene pipe, you can use a method that involves the use of special fittings. This technique has many advantages, among them, in particular, increase the speed of installation of water disposal and water supply systems, reduce the possibility of leaks, which may occur during butt welding or chemical bonding. Among other things, the described technology is less time consuming, and also involves less power consumption. Among other things, it is associated with less material intensity. Installation works are quite cheap. With the help of fittings and glue it is possible to connect pipes of all possible diameters, which range from 6 to 400 millimeters.

Comparison of cold soldering with mechanical and welded joints

Before you connect a polypropylene pipe to a polypropylene pipe, you should consider all the advantages of a cold soldering process. Thus, this technique, with a low material-intensity, speed and quality of the work carried out, is not inferior to traditional welding. Such a technology of gluing does not provide for the use of special equipment, which greatly simplifies manipulation. Do not have to use a special apparatus designed for welding, which during operation consumes quite an impressive amount of electricity. Due to this, it is possible to reduce the cost of installation work. If you are faced with the task of how to connect a polypropylene pipe to a polypropylene pipe, then it's worth comparing the glued joint with fittings and mechanically coupling the elements. The latter technology is not so energy-intensive, but more material-intensive. This is due to the need to purchase additional fittings, which leads to more expensive work.

Features of connection with fittings and glue

If you do not know how to connect a polypropylene pipe to a polypropylene pipe, it is important to familiarize yourself with the technology of cold welding. To do this, use the adhesive, which is intended to connect the pipes with parts by the type of fittings. The latter are most often made of chlorinated polyvinyl chloride. The adhesive after the application begins to dissolve the surface of the parts by 1/3 of the thickness. This makes it possible to realize diffusion cold welding. This process is affected by the temperature and humidity of the air. Before connecting polypropylene pipes with cold welding and fittings, you need to make sure that the ambient temperature is between 5 and 35 degrees. If there is a need to carry out installation work at a temperature below zero, you should purchase a frost-resistant adhesive, which can be applied until the thermometer mark drops to -18 degrees. If the work is carried out in hot weather, the gluing should be carried out in a much shorter time, which will eliminate the possibility of drying the composition until the moment of accomplishing the manipulations. Before connecting polypropylene pipes with the described technology, it is necessary to make sure that the glue has a uniform consistency, sufficient fluidity and has no foreign inclusions.

In the intervals between the work, the container with the adhesive composition should be closed as tightly as possible, which eliminates the evaporation of the volatile active components.

The technology of connecting pipes with fittings and glue

If you decide to use the method of cold connection, then you need to use the technology described below. At the first stage, it is necessary to cut off part of the pipe in such a way that it is possible to obtain an element of the required length. For which it is recommended to use a pipe cutter, a special scissors or a hacksaw for metal, the latter of which has rather small teeth.

If you are thinking about how to properly connect polypropylene pipes, then the next step at the end of the product chamfer, while it is important to observe an angle equal to 15 degrees. In the process of carrying out these manipulations, a facelift is used, it is important to exclude the formation of burrs. The next step will be a thorough cleaning of the socket of the fitting, as well as the pipes from dust, dirt and moisture.

Council of the master

In order to achieve effective cleaning of the joined elements, it is necessary to use cleaners designed for pipes made of CPVC. With the help of this composition, it will be possible to sufficiently prepare the surfaces for further gluing.

Nuances of works

If you are faced with the task of how to connect polypropylene pipes without a soldering iron, then at the next stage it is possible to apply glue. Use this brush, carefully distributing the composition along the surface of the socket and the pipe. Elements are inserted into each other, to evenly distribute the composition, it is necessary to rotate the fitting 90 degrees relative to the pipe. The parts are fixed for 30 seconds, during which you should not re-rotate. The whole process is important to complete within 1 minute. If you are thinking about how to connect polypropylene pipes without soldering, then after the end of the gluing you need to check the presence of a roller, which is a uniform adhesive layer, located along the circumference. You may need to get rid of the excess amount of glue, using a soft rag.

Why use a cold method of connecting plastic pipes

Before connecting polypropylene pipes with fittings, you need to weigh all the positive negative aspects of other technologies. If we are talking about an adhesive joint, which was described above, then it is worth highlighting the advantages that it is possible to carry out a qualitative installation of pipes even in places where access is particularly difficult. The master does not have to use additional expensive equipment, which can consume a large amount of electricity during operation. The entire process is possible to implement independently, without resorting to the help of professional companies. In the process of bonding the parts, a monolithic type of structure is formed, which ensures tightness of the joint. If you decide to use glue cold welding, then unlike the usual, on the inner surface of the product there will be no buildups that are able to narrow the clearance and contribute to the settling of solid particles.

Conclusion

If you observe the joining of polypropylene pipes with each other, following the simple rules and recommendations described above, leaks and sagging of the pipeline will be excluded. The service life of the pipeline, mounted by this method, can reach 50 years.
