Operation and laying of pipes
PVC pipes can be used for the installation of water pipes, and also for them it is possible to transport gas and liquids that contain chemical and aggressive substances, with a temperature of no more than 45 ° C.
The installation of polyvinylchloride pipes must be carried out in accordance with certain rules, namely:
- when installing plastic water pipes, it must be taken into account that such material is sensitive to low temperatures and the poet will require additional thermal insulation;
- PVC pipes are used to equip pipelines where the working pressure does not exceed 0.16MPa.
Properties of PVC pipes
Polyvinyl chloride products are often used by owners of country houses and gardeners for water pipes, swimming pools or irrigation systems, that is, if this design is used in the warm season. The installation of such systems does not require much money and physical effort. Manufacturers of PVC water pipes offer in their assortment a large selection of plastic fittings for connecting pipe sections with each other and with metal pipelines. In addition to the water pipe, it is possible to install a drainage system or a drainage system from plastic pipes.
The main advantages of plastic pipes are as follows:
- low price and low weight of parts;
- easy installation of the water pipe with your own hands, thanks to the presence of a sealing ring and bell;
- installation without the use of special mechanisms and devices;
- can save money, and do not invite plumbing, but to install a plastic water pipe with your own hands;
- such pipes do not rust, and therefore the water is always clean and without a specific odor;
- PVC pipes for water supply do not accumulate on the inner walls of organic deposits, and remain free for head. For the same reason, they are very durable( the manufacturer of PVC pipes gives a guarantee for a period of 50 years);
- such a pipeline can be used for any, even aggressive, liquids;
- plastic pipes can be bent in different directions, thereby giving the desired shape of the entire water supply structure.
Connect PVC pipes with special glue or cold welding method. Joints come out strong and airtight and are not inferior to welded or threaded joints.
However, in addition to the merits, it should be noted and the shortcomings of plastic pipes:
- such a water pipe does not withstand high temperatures, maximum - + 65 ° C;
- when using plumbing from plastic pipes during cold weather( when the thermometer's column drops by -10 ° C or less), a thorough warming of such a system is required;
- is a problematic disposal, since it is impossible to burn polyvinylchloride - toxic chlorine is released.
Assembling the water pipe from PVC pipes
The installation of PVC pipelines will perform the connection of pipe sections with components in the following ways:
- using couplings;
- in the socket;
- by the method of cold welding.
Water supply plastic fittings for connecting pipelines use the extraction of taps in different directions. In addition to water pipes, PVC fittings are used to transport flammable gases in heating systems. In addition, they can be used as protective channels for cable routing.
