Water and gas pipes are widely used around the world – this is a tool to ensure the performance of most enterprises and the usual comfort of each of us.
The manufacture of these pipes is put to the level of widespread production. There are many factories for their manufacture, a huge number of technologies and materials that are used in the production of water and gas pipes.
During the construction of various kinds of communications, a water and gas pipeline with an enhanced electric weld is used, which also differs in special characteristics, which enhances the reliability of its application:
strength – the ability of the material to resist destruction, an irreversible change in form (plastic deformation) under the influence of external loads. The strength depends not only on the natural properties of the material, but also on the technology of the production of the product – compression, bend, stretching, and relative to the aspect of operation – the duration and number of load cycles, its speed, temperature, and the factors of the environment of the environment. Given the above, the main strength measures are allocated: the limit of fluidity, fatigue, strength;
bend – the degree of deformation of the product under the influence of the external environment. First of all, this is a curvature called curvature. There are several types of bends-these are transverse, longitudinal, clean and transverse-proper, each of which is taken into account in the production process;
compression and stretching;
hardness;
elasticity;
shock viscosity – the ability of the material to withstand the impact forces;
heat capacity – a physical quantity, which is characterized by taking into account the influence of an infinitely small amount of heat on a change in its own temperature;
heat resistance – the degree of confrontation with high temperatures;
corrosion resistance;
Erosion resistance.
Each of the above indicators is mandatory taken into account in the manufacture of water and gas pipes.
These pipes are made from various types of steel (often the special alloy content is used), and the process of their manufacture is very laborious and complex, since these pipes differ in the number of criteria and features that must correspond to. Many scientists today are looking for a replacement of material for the manufacture of these pipes, since the use of metal has significantly affects the price.
