I work as a plumber, for the whole time of work, not a single kilometer of pipes have been digested. I think they can give a couple of tips for novice specialists and home craftsmen. Experienced plumbers can pass by the article, although no, I expect comments from you, like this "Vasyan, everything is not so, do not teach why you are taking away our bread."
Meanwhile, my dear student, we proceed:
In order to learn how to apply "diffusion socket welder", yes, yes, that's what it is called, you should get hold of this device. It is better to buy my recommendations once for 1000-1500 rubles than to beg him from a brother or a matchmaker, and then also be responsible for the breakdown of a possible rundown. A device for such a price will be ideal both in price and in functionality, for performing a small amount of work. Do not forget that it must have nozzles with a diameter of 20-25 mm, at least, although they are "crappy", they are sufficient to complete the task of self-education.
Do not forget that cheap devices for welding polypropylene are not equipped with special scissors, and this is + 300 rubles to the price of the welder.
At this point, some of the readers will doubt, pppfff, and it is not easier to invite a plumber for the same money to perform one-time work than to spend money on equipment. I’ll say right away, it’s not easier, don’t you really have a desire to master something new. In addition, sometimes the price of calling a plumber is comparable to the price of the equipment we are considering.
Okay, I persuaded you to buy a welding machine and scissors, what's next? And then you have to understand what you can do with it. If you have a vegetable garden, a summer residence, or you generally live in a village, then I don’t understand how you lived without him. Firstly, water supply can be made or upgraded from polypropylene. All kinds of structures can be made from pipes and fittings. And if you are a creative person, then the welding machine is simply recommended to you.
So, you bought a device and scissors and happy heading home... But, unfortunately, not all, we should purchase a piece of pipe, two meters are enough and fittings, under this word the details of the pipeline are hidden. It is necessary to purchase tees, couplings, angles, 10 pieces of each item. The price of products is on average from 5 to 10 rubles.
Practice
Everything, now we are heading to practice, for this business is suitable: a garage, a shed or a workshop. And if you have nothing of this, then we are placed in the kitchen, turn on the hood and open the window. We open the welding machine, install the nozzles on the soldering iron tip. We turn on the network. While the device is gaining the set temperature, which is about 260 degrees, you are reading the instructions. We study the page with the time of welding fittings and pipes in a socket, in each device it has its own.
Next, cut off a piece of pipe with scissors, 20 centimeters. Take it in your hands on one side, and the fitting on the other. After waiting for the signal from the welder that he is ready, we plant the pipe and the part in the socket, wait for the set time, according to the instructions.
We take out and connect the fitting to the pipe. The first time, many do not succeed and this is normal. But we bought 30 parts, and each one has at least two holes. It turns out that we can practice more than 60 times. But not just practice, but cut the fittings with scissors and watch how the parts are soldered. Is there a narrowing. If you do this many times, then you will understand how long to keep the pipe in the soldering iron so as not to overheat the material. You will feel your apparatus. What will increase your skill in this "simple" business. After that, you will be able to carry out the work described above. But as a plumber, I warn you, please do not use your skill in apartment buildings where there is a chance that you could flood your neighbors. Leave us our bread.
