Tip 1: How to Choose a polypropylene tube

Before many people raised the question of choice of polypropylene pipes.Special work this thing does not make.However, it is best to seek help from a specialist.They can give good advice.In any case, you must have reliable information about the propylene tubes.
Guide
1
First we need to pay attention to the conditions under which the operation will be made of pipes.Immediately it should be noted that the durability of polypropylene pipes affects the operating pressure of water supply system, as well as the temperature of the transported water.
2
Currently on the market can be purchased pipe different species.Each species has its clear purpose which can be found on the label.The most commonly used polypropylene tubes type PPH, PPB and PPR.
3
pipe with the acronym PPH can only be used for the ventilation system or water supply system with cold water.Marking RTD is on tubes, which are used for floor heating systems, as well as cold water.They have a high level of impact strength.
You can often find pipe marked PPR.They are universal.Apply such pipe for different heating systems, as well as for hot or cold water.They have a fairly stable form, as well as an excellent level of resistance to temperature effects.In addition, there is a uniform load on the walls of the pipe .
4
the polypropylene tubes are also disadvantages.One is a high coefficient of thermal expansion.That is why the hot water system must be used reinforced pipes .In polypropylene tubes attaching reinforcing aluminum foil.With this foil is a decrease resizing pipe during thermal exposure.It also creates an obstacle to the penetration of oxygen pipe , which passed many polymers.
5
When selecting pipes sure to pay attention to the quality of their performance.The inner and outer diameter of the pipe must be perfectly round.It may be considered on the cut.

Tip 2: How to choose a plastic pipe

Scientific and technical progress over the last two decades has made a truly amazing changes in human life.Huge selection of hardware, tools and building materials, increasing their quality and simplify the technologies today provide such opportunities, which had not even dreamed of.So, every day is becoming increasingly popular to use plastic pipes.But what exactly to choose from the variety of available options?
How to choose a plastic pipe

of polybutylene pipes
Polybutylene in comparison with other polymers, more resilient and heat conductors, such pipes are able to withstand the temperature of the fluid up to 90 degrees.In connection with what they are used for installation of "warm floor".
2
polyethylene pipes
They are pretty durable and resilient.Is a good insulator.Polyethylene distinguish high and low density.High density polyethylene is stronger but less elastic.These pipes are used for the cold water supply.They are ideal for holiday water pipe installation, because due to its flexibility tolerate freezing water, without damaging the pipe.Connect welding.In European countries often make the water from the so-called "cross-linked" polyethylene.It can be used for hot and cold water and heating.Connect gasketed fittings and crimp.
3
tubes of polyvinyl chloride (PVC)
They are the most stringent of all polymers.Such pipes are resistant to aggressive chemicals and UV radiation.They have a small specific gravity and low flammability.The downside is the presence of chlorine in the mix. pipes are interconnected by gluing.
4
Pipes polypropylene
They are used according to the labeling for the hot and cold water supply, sewerage, heating.By thermal and physicochemical properties of polypropylene are very close to cross-linked polyethylene, but their advantage in contrast to the latter is the lower price and ease of installation.Connection by welding.
5
Thus, for the average Russian consumer, who wishes to engage in self-assembly and pays special attention to the relationship quality / price, the most appropriate option would be tubes made of polypropylene or polyvinyl chloride.
Note
polypropylene pipes are not afraid of corrosion, are resistant to the negative effects of corrosive environments;over time, polypropylene pipes do not exhaust the limits of their skills and maintain a smooth inner surface, provides quick and easy circulation of water in heating pipes How to choose polypropylene pipes for heating?
Helpful Hint
latest generation of pipe - the pipe is made of polypropylene.Compared with other pipes, polypropylene pipes have several advantages over low heat · - no loss of heat, which makes it possible not to apply the pipe insulation.As a consequence - the lack kondensana on the outer walls of the pipe.· Heat savings during transportation in polypropylene pipes for hot water is from 10 to 20%, as compared with metal.
