Step by step instructions for welding polypropylene pipes with his own hands

for repairs in the house (apartment), laying of water pipe, heating system or arrangement of sewerage systems in the country are increasingly used pipes made of polypropylene.They last longer, and lighter, and easier to install.The advantages compared with metal pipes much.

However, it is believed that the welding work to connect polypropylene pipes is only possible when using some sophisticated instruments and highly professional skills.But the reality is much simpler.It is only necessary to understand the principle of this work and follow certain guidelines - then welded polypropylene pipes is quite possible with their own hands.

The first thing to know that foreign manufacturers in each product there is its own standard.In other words, there is no single guests, which we are accustomed.To connect pipes may need more and different fittings, about which I wrote earlier (transitions, corners, etc.), which will have to buy.They should be made of the same material - polypropylene.Moreover, it is desirable that pipe fittings and are from the same manufacturer.Then when they do not have welding any difficulty.

For welding pipes need only one power - it is called and apparatus for welding polypropylene pipes, and a soldering iron pipe, and "iron".That made it heating the material.Its cost is approximately within 3 - 4 thousand, so you can not buy, if the work is to be "one-off".It is better to ask friends (if possible) in the "rent."

pipe welding Methods

1) Preparation of all parts

To avoid confusion during operation, you should prepare in advance all the elements of "schemes".Make the necessary measurements, the cut pieces of pipe of predetermined length.Sections of pipes and fittings need to be expanded in the order in which they will be connected by welding.This will eliminate the possibility of incorrect connection of the pipeline sections (scheme).It should be understood that if the threaded connection can unwind and remake, the elements, welded unit, can not be disassembled.They just have to throw out.

2) Reheating soldering

It has a thermostat to be put on the recommended limit instruction.After heating to the selected temperature goes out warning light thermostat.

3) Heat "details»

to connect circuit elements (pipeline) need to be warm.Connecting surfaces are heated, and then joined together.There is their "fusion" that provides reliable and tight connection.Therefore, parts to be joined are inserted into respective sockets of the welding apparatus.How to do it, detailed in the instructions on the "soldering".It is only necessary to study it carefully before using the product.

4) Crimp "details»

Heated parts fit together smoothly and quickly.Not allowed turns around the longitudinal axis misalignment.If you connect two pipe segment, it is necessary to strictly sustain the cutting angle - only in this case, a reliable and hermetic seal /

5) Brushing the junction

seam is produced after cooling.

Tips Welding

Before starting work on the assembly (welding) pipe system, it is desirable to practice.Therefore fittings need to purchase a little more than necessary.And to cut a few pieces of pipe - not a problem.After this training will experience in this type of welding, and hence confidence in their own ability.

Before welding the elements necessary to prepare - joined surfaces are degreased and stripped.Without degreasing quality seam will not work.

Fill collected water system is recommended not earlier than 1 hour after the welding elements.
