Polyethylene pipes are so practical to use that they almost occupied the entire niche in terms of sales, displacing traditional metal pipes. This is primarily due to the characteristics of HDPE pipes.
Polypropylene pipes have a number of advantages:
Initially, when assembled, polypropylene pipes were not soldered. Used special glue for bonding .
In some countries with small diameter pipes indoors, this is still the case.
But brazing reinforced polypropylene pipes is easy and cost effective.
To braze polypropylene pipes with your own hands will need so-called fittings. These are special connecting elements, often in angular form.
They differ in shape.
There are different materials, homogeneous or several, for example, metal with plastic. And they are used in different works:
But it must be borne in mind that the thread often flows, and brazing is a better connection. The thread is sometimes sealed with improvised means.
Allows you to make the connection of pipes at the desired angle.
Of the specific tools of the type, only special scissors and a soldering iron for pipes are needed.
Scissors are of two types, depending on the diameter. Sometimes a shaver and beveller are used.
The welding machine is a structure with different holes.
Special soldering nozzles are attached to these holes with different diameters.
The set includes a variety of specially coated attachments that require gentle care.
There are several types of devices designed for different powers. Accordingly, for different diameters. The work temperature is regulated by a special switch.
Shaver is a special device for cleaning the reinforced layer from the surface of the ends.
A beveller is used to remove unnecessary plastic and level the surface.
Before you start soldering, you need to make a preliminary project.
All joints and lengths of the segments should be visible in it, as well as the attachments to the surfaces. Such work will reduce the likelihood of errors.
Next, you need to make the correct markup .
This is one of the most important stages of work.
Also calculate the required amount of material . If done by analogy with old systems, then they are measured.
The material must be purchased with a small stock. If pipes were not soldered before, then you need to take longer communications and additional fittings for training.
Workpieces are made in advance - the required pipe lengths are cut. To do this, add 30 mm to the distance between the fittings. Then cut with special scissors exactly at 90 degrees. Then the fitting is attached, and the distance is noted. The longitudinal mark helps to connect the pipe elements along the axes.
When brazing reinforced pipes, they pass through the ends with a shaver to clean the surface. The fasteners are made with such a diameter that they can only fit pipes without the top layer.
How to solder polypropylene pipes .
It must always be on.
And the appliance heats up for about ten minutes. The indicator will indicate readiness.
The time is 4 to 10 seconds.
There should be no cracks or creases. Allowable shift is the thickness of one wall.
In fact, the soldering process is quite simple. In this case, the technology must be observed.
You can see how to solder polypropylene pipes in the video. Work is best done with gloves.
