Hello dear subscribers and guests of the channel!
In Soviet times, almost all sewer pipes were made of steel. In rare cases, stainless steel or galvanized steel was used for plumbing. This is due to the fact that in the USSR the pipe-rolling industry developed by leaps and bounds.
In Soviet apartments, the pressure pipes were also made of steel. My dad even found those times when, when a steel sewer failed, the repair team had to drag a hose from an acetylene generator to a call. If the call was on the upper floors, it was especially difficult for the repairmen.
Those who have worked with galvanized pipes are unlikely to forget this. When pipes were welded with gas, the protective zinc coating burned out. Zinc compounds got into the smoke, and then into the lungs of the repairmen, where they settled.
That is why, after the shift, the person was given a liter of milk. Otherwise, the next day, the worker could simply not leave for the shift. Because of this, the entire team suffered.
Currently, sewer pipes in houses and apartments are predominantly made of plastic.
- 1. In apartments, as a rule, polypropylene or metal-plastic pipes are used (the latter are less common). In recent years, it has become popular to install XLPE plumbing in apartments. It has good performance and a long service life.
- 2. When sewers are laid down the street, they often use HDPE - low pressure polyethylene.
Such pipes are simple and quick to install, and their transportation is also not difficult. Repairmen are very fond of working with plastic.
Why did people stop using steel pipes in their apartments?
The popularity of plastic pipes is due to the following factors:
- Steel pipes have a short service life, especially if untreated hot and cold water flows through them. As a result, the pipeline is covered with corrosion from the inside, clogged. As a result, fistulas appear on the pipes, which threatens to flood the apartment.
- In the late 1990s, Czech and Turkish polypropylene appeared on the market. Its main advantage was its cheapness. In addition, it is easy to use, its installation does not require any special investment of time and effort. Plastic does not rust and has a long service life. Manufacturers claim that plastic sewers can last up to 50 years.
Output
The number of gas welders in housing offices has sharply decreased. Today they mainly have to work with heating systems. Since the brigades have been reduced, the expenditures of house administrations on their maintenance have also decreased.
Nowadays, a small team or even two locksmiths for ten multi-storey buildings is enough. Surprisingly, this does not make it easier for ordinary people, the rent has both increased and increased. Home maintenance has cost and continues to cost residents dearly. Here's a paradox.
Afterword
In the Soviet Union, there was an opportunity to establish the production of polymer pipes. However, the government was not farsighted, the chemical industry in the plastic sector did not develop. Steelworkers seized power and prevented the polymer industry from moving forward. Therefore, we got the opportunity to use imported materials only in the late 90s.
