Not the only but serious problem of many utility services of large and small cities remains the water supply and sewage system. The reason for this is the pipe that has long survived their resource. Replacing all hydraulic systems is quite labor -cost and expensive process. And the need to carry out such work is growing every day.
The question is still which material to use. Steel pipes are sensitive to sharp temperature differences and are constantly rugging. If you want to buy flanges in Kyiv, we advise you to follow the link given.
Therefore, now metal pipes are almost not used, the installation of plastic and metal -plastic systems is an alternative. With their help, it was possible to solve many problems at the same time.
Plastic pipes are more resistant to temperature drops. The cost of the material and installation is relatively not high. Less time and labor costs when installing. Strong material provides 5 times more service life. In turn, plastic pipes are divided into:
-polyvinyl chloride (PVC)
-Chlorinated polyvinyl chloride (HPV). Has a larger temperature range than PVC. Used in the chemical industry due to resistance to aggressive environments.
