Plastic pipes meet all the requirements for safety, they are durable, can reduce the cost of construction and maintenance of buildings.On the market today you can buy tubes foreign and domestic, with high quality products are produced abroad and in our country.Imports often come from Turkey, Germany, Czech Republic and China, the price for the most part does not exceed the value of its Russian peers, however, and quality too.

Plastic: the pros and cons

What features are common to all, without exception, pipes made of plastic?It:
- durability (service life of such pipes for over 50 years),
- resistance to rust,
- low thermal conductivity,
- lightweight,
- environmental friendliness and low noise.
Grey polypropylene market is presented to the Chinese model, reinforced - R
ussian brands, and white plastic is diverse and in the price range and the technical.

course, have plastic pipes and disadvantages:
- firstly, in hot heating applications can be installed is limited and systems fire line they do not fit,
- secondly, each type of polymers hasespecially installation and, therefore, have a master specialization and their services are more expensive.

Types of plastic pipes

In the market of building materials you can buy plastic pipes of several types:
- Polypropylene (PP) pipes,
- pipes made of polyvinylchloride (PVC),
- polyethylene pipes (PE),
- pipecross-linked polyethylene (PEX),
- metal and plastic structure (PEX-AL-PEX),

PVC pipes are used in a long time, PVC was used for the production of pipes one of the first materials.Polyvinyl chloride, used in the production of environmentally safe, recommended SNIP, pipe it can be used in the food industry, in hot and cold water supply, sewage systems at the device.

PVC pipes are easy to use, for installation requires no special tools or special skills.Pipe connection occurs by simple connections using a "cold welding", and combine them into the socket, with the rubber sleeve.It should be remembered stiffness pipe, you must attend to the presence of fittings for connection.PVC pipes can be laid or hidden from the outside, and in any embodiment, the value of the pipeline with such materials will be low.

Polypropylene pipes may be monolayer and multilayer, wherein the multilayer pipe subdivided in turn into three subtypes:
- foil reinforced top working layer mounted on the adhesive coated propylene,
- tube, foil and the protective layer are joined perforations,
- layered construction in which no plastic polypropylene sandwiched between two layers of the base material.

Polypropylene products are very light, so even the installation of pipes of large diameter may make only a couple of people.As compared with polyethylene tubing PE-analogues have significantly higher heat resistance and can be used at a flow of 80 degrees C. At low temperatures, they lose their elasticity, and because they are often used for routing external water supply to the same section of the pipe is notdecreases due to overgrowth and deposits.
These pipe fittings are equipped with a thread, which makes it possible to install them in a ready-pipe systems.
Polyethylene pipes are also designed for indoor and outdoor water pipes (water, sewage, waste, etc.), but the polyethylene has the lowest minimum temperature among peers - to -20 ° C.This parameter is important to consider where will the installation of pipes in the cold season.

crosslinked polyethylene without drawbacks simple polyethylene, in particular, it is resistant to temperature changes.The process of "cross-linking" has nothing to do with a mechanical tube, we are talking about the manufacturing process of polyethylene, the material in the production process by special technology, allowing the molecules form an additional bond, "stitching".This makes polyethylene pipes robust, reliable and durable, but the installation is important to prevent the ingress of free oxygen in the water supply system - this is done by diffusion barrier which covers the pipe.

pipes made of polymers (plastic pipes) may be called the youngest in the market - their production process started about 10 years ago.Pipes can maintain the shape during bending, they can withstand high thermal loads and are capable of operating at pressures up to 10 bar.Pipes are resistant to wear, have minimal thermal expansion and impermeable to gases - and it's all thanks to a layer of foil, located inside the pipe.

Regardless of the type of plastic pipes allow to lay durable, economical and safe water, sanitation, waste, taking into account all the modern requirements for the engineering systems.
