Traditional materials, which are still used along with plastic pipes, such as iron, steel, concrete and others, largely inferior to the latter, although made of very durable material.
The main disadvantage of the use of metal tubes is that they are too prone to corrosion. Moreover, metal pipes, as a rule, have a worthless property accrete on its inner surface. In contrast, plastic pipe can last a very long time without the formation of a plaque on the inner surface.
That is why many of the steel pipes that are installed in pipelines must be changed often enough, because they literally attract all the pollution. Overgrowing pipes in this case may lead to a significant reduction in their cross-section. As a result, this may be a need for additional energy consumption for pumping water. For this reason, sales of steel pipes has been reduced considerably, and their production also decreased.
The undeniable benefits that PEX pipes have long been proved: the reduction of time on their pad and a significant reduction of negative environmental impacts. Sale of pipes made of polyethylene are also more profitable from an economic point of view. Plastic pipe, including PEX pipes, not only contain cheaper materials, but they are also much more convenient and less expensive to mount and replace with new ones. Sale of pipes made of polyethylene are also more profitable because of the significant increase in the life of products.
