Where are the glass tubes used?
There are substances that can not be entrusted to metal pipes for the simple reason that in an hour the steel walls will turn into a sieve, or the seams between the sections will leak out. In general, a lot of liquids and gases have an extremely aggressive effect on the metal and are neutral to the glass. Therefore, glass pipes - the only way to create pressure or non-pressure systems for the transport of such substances.
In the canals of glass, sometimes lay cables, this is especially true where the braid of wires can be damaged by rodents.
For the most part, glass pipelines are used in the chemical industry, often they can be found in shops of various food factories. On pipes of glass, characterized by high sterility, milk flows on automated farms, where mechanisms milk cows and goats.
But if this material is so in demand in production, it does not mean that you can not use pipes from it in your home. Fireplaces require qualitative chimneys, and since not only brick, but also metal, along with glass, is required to build fires, so why not use heat resistant chimneys from the latter.
The main characteristics of glass pipes
The glass industry produces pipes manufactured in two ways: horizontal or vertical stretching of the mass. The latter option is more suitable for the production of large diameters. When the mass is almost frozen, it is cut into sections of the required length, the edges of which are thoroughly polished, so that the ends do not pose a danger to those who will have to work with these engineering elements.
Compositions for glass pipes are used different, for example, the same compositions as for window glasses , as well as borosilicate, non-compact, low-alkaline, molybdenum and some other, complex components. The elasticity of the walls of such pipes can be in the range from 45 to 80 MPa, the tensile strength often reaches the same 80 MPa, and the compression at 1200 MPa. Such a material is difficult to call brittle, and it is not necessary to doubt its durability, for example, glass tiles can serve as an example.
The length of the sections can be from 1.5 to 3 meters, and shorter shaped parts, such as drifts or couplings, are used, as well as tees with taps, used to create branched networks of glass channels. The diameters are specified by standards, these are 40, 50, 80, 100 and 150 millimeters. Since connections of sections of different diameters are frequent, for such cases transitions are made, for example 40/50 or 100/150, in other words, for diameters closest to each other.
Pipes made of glass - instructions for use
If you decide to use pipes made by the glass industry in your home, you need to know that keeping this fragile material in the open air is not recommended for a short time. The fact that many components of the material begin to leave its structure under the influence of moisture and carbon dioxide, which saturated the atmosphere. If you suddenly find the glass to be unclear, you can solve this problem with an 8% vinegar solution or just hot water .
To connect individual sections to one system, you will need a hole punch screw, rubber sealing rings, flanges and special pliers for working with them. Preliminary it is necessary to prepare the brackets on which the glass tube will be fastened, then a section of two sections is assembled directly in place with the help of a hose and flanges, each of which has 2 or 3 gaskets.
Pulling the flange with ticks, the connection is tightened with a wrench until the rings overlap the T-piece slightly. Flanges should be spaced from each other at a distance of 4 to 6 millimeters.
