increasing popularity of polypropylene pipes contribute to their advantages such as long life, light weight and relative cheapness.But they also have another huge plus.This ease of installation.
Plastic pipes can be connected in three main ways: by gluing, crimping and welding muff.In this last mentioned method it is the most simple and reliable.To carry it out, do not need any additional mounting parts.It is enough to have only a machine for welding polypropylene pipes.
As welded polypropylene
connecting seam is the result of the diffusion boundary layer polymer abutting portions.In order to give plastic molecules the freedom and flexibility sufficient for mutual penetration, the material must be heated to an amorphous state of fluidity.After that, you just press the mating edge of one to the other and stand in the stationary long enough to cure the joint.
clear that manually, using handy tools like a soldering iron, iron or other household heating devices, to carry out this work is difficult, if not impossible.
All of these operations are performed welding machine for polypropylene pipes.The mating portion of the mechanical strength is not inferior to the quality of any other segment of sanitary wiring, but the success of the successive process steps necessary to comply with certain regulations.Firstly, the mating edges should maximally tight to each other, and therefore, they must be very precisely cut at right angles.Second, it should strictly maintain the temperature regime.In case of excessive heating of the plastic "flow" and be deformed entire item, which must be assembled, and if the heat is not sufficient, then the seam will unstable because of insufficient diffusion.
for pipes of large and small
Apparatus for welding polypropylene pipes - equipment, usually a professional and acquire its plumbing course of their work faced with the task of installation or repair of house or external communications.These devices may be small, if intended for use with piping diameters up to 120 mm, or rather overall, when it comes to large sizes.Accordingly, the "high-caliber" pipe, the stricter the requirements for density and accuracy of the compression edges, because the whole process cycle is limited to a period of hardening of the heated layer.
Apparatus for welding polypropylene pipes of large diameter necessarily equipped with a gripper ring groups, through which the mechanical pressing soldered edges.At the same time a similar device for the ordinary running water, much easier, and consists of a planer (rotating disc knives provide a flat surface of the connected part) and heater, equipped with Taine and graded temperature regulator.
Selecting device
Each master, depending on the range of its work, can choose the most suitable device for welding a polypropylene pipes.The price of this equipment depends on its flexibility, power, and complexity of the device configuration.Each size of the pipe and fittings are manufactured nozzle of suitable diameter, coated with non-stick layer to eliminate adhesion of the melt to the surfaces.The most affordable in terms of price are usually the easiest welding machine.
For welding of polypropylene pipes in the home with small amounts of work conditions can be used so-called "iron."Despite the apparent dissimilarity, the device is so called because of its resemblance to the basic principle of the working of the heater in the economy of this useful object.It consists of a heating element, thermostat and heating plate with holes of appropriate diameter.Using them is easy, but it is recommended to practice first on a piece of pipe, to obtain the necessary skills.
