Pipes of NSAIDs
Plastic pipelines today are increasingly used in the construction of new buildings and in repair work at already functioning facilities. Quite often, pipe made of polyvinyl chloride, which are designated as PVC or NPVX, become their basis. These building materials have many advantages over their metal analogues, the main of which is the lack of a tendency to corrosion and overgrowing from the inside.
NPVX pipes are covered with a smooth inner surface, so they have a pressure loss of 30 %less than in such products made of steel and cast iron. No matter how much time has passed since the beginning of the operation of such a plastic pipeline, he will have no deposit inside him.
Due to its high elastic modulus, which is 3000 n/mm, NSA pipes demonstrate resistance to hydraulic impacts. The danger of a rupture of such a pipeline is reduced due to an elastic perception of the external load. During tests for the resistance of prefabricated bell -knit nodes with a rubber cuff, conditions with a temperature of 20 ° C and a constant internal pressure of 32 atmospheres are used.
One of the features of polyvinyl chloride is that this material does not become the environment for the propagation of bacteria. NPVX pipes can be used as part of drinking water supply systems, since they do not affect the organoleptic properties of water . PVC has no smell and does not give the water any extraneous tastes.
NPVX pipes meet existing standards regarding the hygienic properties and safety of products for the human body. A high sanitary and epidemiological level of such plastic pipelines is also achieved through the use of shut-off valves in the form of disk rotary shutters.
Another advantage of NSAID pipes is their low electrical conductivity, thanks to which wandering currents do not occur in the pipeline. This means that the system does not threaten damage due to electrical corrosion. The lack of accidents in water and sewer networks is a great achievement of engineering.
It is impossible not to mention the economy of the use of NPVX pipes, due to their small weight. The specific weight of these products is approximately 20% of the weight of metal pipes. It is clear that there is also benefit during the transportation of products and when installing them. Laying of plastic pipelines passes without involving powerful lifting equipment.
Installation of pipelines from NSAIDs is not a complex process, since it is carried out using trifling joints through the sealing ring without the use of welding equipment and highly qualified personnel. Any sizes of NSAID pipes can be quickly assembled into the system using fittings. If necessary, you can always dismantle without damage to the connection.
