Application area polypropylene pipes- mainly - heating, plumbing, and technological installations.
Polypropylene pipes
characterized by strength, absence of corrosion, resistance to aggressive environments. Simple installation using sleeve welding, easy transportation. Subject to operating conditions, the service life of these pipes is at least 50 years.
With the development of technology, new materials appear on the market that are superior in their characteristics to their predecessors. In the field of communications, old metal pipes are being replaced by modern ones made on the basis of polymers.
One of the most popular materials in heating systems and water supply is polypropylene (PPR in the Russian abbreviation or PPR in the international marking). Polypropylene pipes have a number of advantages, due to which builders are increasingly leaning toward them when laying sewerage and heating systems.
Polypropylene pipes are used in the installation of communication systems in residential buildings, public buildings, as well as technical and production buildings:
- for supplying drinking water,
- in cold water supply,
- for filing hot water,
- V central heating premises,
- for installation of heated floors and walls,
- in irrigation of farmland,
- at industrial enterprises,
- in fire safety systems,
- in swimming pools and other sports facilities,
- in shipping and so on.
Depending on the diameter of the pipe and the presence of additional layers, polypropylene products are used for laying both household pipelines and highways.
Types of PPR pipes
There are several types of polypropylene pipes:
- PN 10 is a product with thin walls that can be used for cold water supply or installation of heated floors. The water temperature should not exceed +45°C. Such a pipe can withstand pressure up to 1 MPa (10.2 kg/cm²). This option is very convenient if the pipeline will supply only cold water, since a thin-walled product requires the least resources for production, and therefore costs less than other types of PPR pipes. PN 10 pipes are manufactured with a diameter from 20 mm to 110 mm, with a wall thickness of 2.3-10 mm. The standard pipe length is 4 m.
- PN 16 has thicker walls and can be used to supply both cold and hot water (but the temperature must be below +60°C). Working pressure in PN 16 pipes is up to 1.6 MPa (16.32 kg/cm²). On average, the wall thickness of such a product is 0.5 mm greater than that of PN 10, which allows it to transport liquids of higher temperatures.
- PN 20 is used to supply hot water (up to +80°C) and can withstand pressure up to 2 MPa (20.4 kg/cm²). This product has much thicker walls, up to + 1 mm compared to PN 10.
- PN 25 are polypropylene pipes that can withstand temperatures up to +95°C, and therefore are used in hot water supply and heating systems. Working pressure - up to 2.5 MPa (25.49 kg/cm²).
Polypropylene products belong to the group of environmentally friendly materials. They are more attractive steel products lower cost and weight, and superior metal-plastic options in strength and durability. Parts marked PN 20 have a wider range of applications, so they are more in demand compared to other options on the market. Let's take a closer look at the technical characteristics of the PN 20 pipe, the properties of the material, its pros and cons.
Features of the material
The material from which the PPR PN 20 pipe is made is random polypropylene copolymer (third type). It was invented relatively recently, which made it possible to use products in high temperature conditions. The main features of the material include:
- High resistance to direct exposure to acidic and alkaline solvents.
- High plasticity, thanks to which products can easily withstand freezing and thawing of moisture inside them.
- Expanded temperature Range use of parts made from this material – from 10 to 90˚С.
- The material is absolutely non-toxic, therefore it is successfully used for assembling drinking water supply systems.
- When processing and recycling parts, no environmentally harmful substances are released.
All these distinctive features were obtained by adding ethylene molecules to the polypropylene molecular chain. By modifying its structure, the indicators of ductility, viscosity and temperature strength were improved.
For self-installation systems will need to purchase a special welding machine. The connection of segments using it is most hermetically sealed and reliable.
Varieties
The pipe in question, marked PN 20, is produced by manufacturers only in a single form and does not have any variations. But you can often hear about purchasing or using reinforced pipe PN 20. In fact, this type of product is produced under a different marking - PN 25. It received the status of a reinforced analogue by mistake, since the external parameters of the products are the same.
The wall thickness of the pipes under these markings will be the same for all existing diameters, but their weight will vary. The heaviest parts are those with an aluminum reinforcing layer, those of medium weight are those with a layer of fiberglass, and the lightest are those that have no reinforcement at all.
Pipes also differ in their maximum permissible temperatures. working environment and working pressure. So for PN 20 models permissible temperature no higher than 80˚С. For parts reinforced with glass fiber, this figure is higher – 95˚C. For parts reinforced with aluminum, short-term exposure to a coolant with a temperature of 100˚C is allowed. The maximum working pressure for unreinforced models is 20 atmospheres, and for reinforced ones - 25 atmospheres.
Scope of application
PP PN 20 pipe is used for various purposes.
- As a water distribution mechanism in residential, industrial, administrative buildings and agro-industrial complexes.
- For laying water supply (hot and cold) indoors and outside buildings.
- For installation of "warm floor" systems, which are laid in niches under the floor covering, or recessed into concrete screed.
- As connecting segments for connecting radiators to the heating system.
- For wiring heating system in rooms where the maximum temperature does not exceed acceptable indicator for the material used.
- For connecting heating systems to boiler systems.
- As systems transporting compressed air or aggressive chemicals.
Do not bend the products. All turns are performed strictly at right angles using adapters and couplings.
Specifications
The marking is deciphered as follows: PPR - random polypropylene (improved third type), PN - nominal pressure. Specifications PPR pipes PN 20:
- Linear expansion coefficient (1/˚С) – 12.7*10-5.
- Thermal conductivity coefficient (W*m/˚С) – 0.238.
- The maximum permissible temperature is 80˚С (to increase the service life of products, it is recommended not to exceed 70˚С).
- The maximum permissible pressure is 2 MPa (1 MPa = 10 atmospheres).
- The wall thickness with a product diameter of 20 mm is 3.4 mm.
- The weight of one meter of a product with a diameter of 20 mm is 170-175 g.
Product advantages
The choice of PN 20 pipe is influenced by its many positive qualities. We list the main advantages:
- Lower cost and weight compared to traditional ones metal products.
- Simple and fast system installation process. Socket welding reliably and hermetically connects the segments (10-15 seconds are spent heating the parts).
- The elasticity of the material allows the products to be used for assembling underfloor heating systems and laying plumbing in unheated areas.
- The material from which the parts are made is non-toxic and resistant to chemical attack.
- The inner walls are resistant to corrosion, and the smooth surface prevents the formation of plaque.
- Resistant to temperature changes and pressure surges.
- The low thermal conductivity of the material eliminates the risk of condensation forming on the surface of the system.
- High level sound insulation reduces the noise level of the system.
- Resistant to aggressive environment, which reduces the cost of additional protective measures(painting, priming and other procedures).
The service life of parts in a heating or hot water supply system is 25 years. The service life of parts in a cold water supply system is twice as long
Technologically correct installation of the system, high-quality connection of its segments to each other and compliance with operating rules will significantly increase the service life of the water distribution mechanism.
Plastic pipes– a modern replacement for old heavy metal pipes. Such lightweight plastic pipes appeared not so long ago, but they quickly gained a strong position among other pipes in the plumbing market.
When choosing a material for a pipeline, you will probably give your preference plastic products, however, choosing a specific option will be quite difficult, because they can be made from a variety of various materials: polyethylene, polypropylene, etc. In this article we will take a detailed look at the advantages and disadvantages of polypropylene pipes, comparing them with analogues.
Characteristics of polypropylene pipes
The PPR pipe has whole line distinctive characteristics, but the main one is the lightness of the product, which is ensured by the raw material - thermoplastic polymer with the lowest density (0.91 g / cc) among similar materials.
The remaining characteristics determine the scope of application of these pipes:
- The operating temperature of polypropylene pipes ranges from -5°C to +140°C, so they are perfect for organizing heating systems, hot and cold water supply, but only indoors. When laying water supply outside, it is better to use sewn polyethylene pipes, which do not deform during cold snaps down to -50°C;
- Plastic does not corrode, which was a big problem metal pipes, Besides, plastic water pipe guaranteed to last at least 50 years;
- The ppr pipe has a smooth inner wall, which significantly increases their throughput, and also does not allow them to become clogged;
- Plastic pipes are completely inert to most chemical substances;
- Polypropylene pipes have a wide range various diameters;
- Installation of PPR pipes is carried out using special fittings, also made of polypropylene. The pipes are welded into fittings using a special apparatus, which you can purchase at an affordable price.
Types of polypropylene pipes
There are 4 main categories of polypropylene pipes:
- P.P.H.– polypropylene pipe with high strength but low resistance to negative temperatures. The main area of application for such pipes is laying cold water pipes in industrial scale;
- PPB– polypropylene pipe, for the manufacture of which polyethylene is additionally used. The result is a durable pipe that is resistant to low and high temperatures. Most often used for laying underfloor heating systems;
- PPR pipes are made from a special polymer that includes ethylene molecules. This mixture allows for special tensile strength to be achieved, so such pipes can withstand pressure surges well. The pipes are excellent for laying cold and hot water supplies, but the water temperature in them should not exceed 70°C;
- P.P.S.-pipes are resistant to high temperatures up to 95°C. Often such pipes are marked with a red stripe.
Reinforced polypropylene pipes
One of the significant disadvantages of polypropylene is its high coefficient of thermal expansion. This is especially noticeable when building a heating system, where polypropylene expands so much under the influence of heat that during installation it is necessary to install compensating loops, which is quite inconvenient.
Manufacturers have long taken care of this drawback by producing reinforced polypropylene pipes.
PPR reinforced pipe also comes in different categories:
- PN20- the pipe is reinforced with fiberglass. When making polypropylene pipes, the manufacturer adds a layer of fiberglass to them, which is later baked into two adjacent layers of propylene. This results in a reinforced structure, which is used when laying hot water pipelines with a large number of joints. Such a pipe also has its drawback - a limitation in the diameter width, maximum size which is 63 mm;
- PN25– polypropylene reinforced with aluminum. The principle of reinforcement is similar to the previous one, but aluminum sheets and profiles are used here. The cross-section of such pipes can be up to 100 mm, but their installation is more difficult and requires stripping the aluminum layer.
