Welding of polypropylene pipes by yourself

Many houses are already very old, you can not be surprised that from the pipes rusty water flows, or its pressure became small. This means that the building has not been overhauled for 25-40 years . In this case, polypropylene pipes will be the best option for replacing old pipes with new ones. Today they are very popular and are sold in almost all construction stores.

In the market, a device for the distribution of polypropylene pipes is quite in demand. This material meets the highest requirements. Recently, it is widely used because it does not corrode, does not deform and does not degrade, does not freeze and does not react to temperature changes, does not violate water quality and is a dielectric. Its cost is much lower than that of metal or galvanized analogs. To install such a pipeline requires special equipment for welding polypropylene pipes.

Soldering polypropylene can be much faster than metal. All bends and joints are one whole. There are no vulnerabilities in them, while they have metal pipes . Pipes made of metal contain joints and welding, which complicates soldering. Before installation, you need to prepare all the necessary fittings and the required lengths. Only after this, polypropylene pipes are welded. It is necessary to conduct heating in order to increase the diameter of the fitting. After that, a pipe is inserted into it a few millimeters. When cooling down, the dimensions of the fitting are reduced, and both elements firmly adhere to each other, thus becoming one whole.

The second method of connection is soldering. It involves heating the two soldering parts with a special soldering device, which then join together in a single piece. This technology for welding polypropylene pipes is quite simple, but it requires great accuracy and accuracy.

Polypropylene water pipe will last at least 30-50 years. Therefore, it can be used for heating and water supply. But welding polypropylene pipes must be done correctly and accurately. When mounting, special fasteners and brackets are used. The flexibility of such pipes makes it possible to make the most complex shapes, and this will take much less time than working with metal analogues. The only drawback of the polypropylene pipeline is that the welded joint can not be dismantled, and the part can be reused. Therefore, you should not make mistakes during assembly.

Welding polypropylene pipes has important points. First of all, it is necessary to degrease welded surfaces. Before welding, the end of the pipe and the inner part of the fitting must be wiped with alcohol. This will remove any residual dust that may damage the coating of the elements. Before welding, it is necessary to make a mark of depth, so that when welding, do not insert the pipe deeper than it should be.

Installation work is better done together. If it is necessary to weld the pipes right at the installation site, one person can not cope with this task. Welding of polypropylene pipes requires precise observance of the heating time. It is between 5 and 30 seconds, depending on the diameter of the pipe. If you overheat, the tube lumen will narrow.
