Production processes
Manufacturers of polypropylene in Russia use a machine such as an extruder for basic work. In it, the material undergoes multi-stage processing and then becomes a pipe. The entire production technology is divided into several stages of work.
The first stage of production is the procurement of the required amount of raw materials. Then polypropylene is placed in a special chamber, and it is usually presented in the form of granules or shavings. Sometimes enterprises use recycled material, it is mixed together with the main raw materials.
When heated to a temperature of 240 degrees Celsius, the chips and granules begin to melt and eventually a viscous plastic substance is formed. Due to the fact that Teflon is applied to the inner surface of the machine, the adhesive substance does not stick to the walls.
Typically, Russian-made products are extruded from an extruder measuring 2.5 meters. Since the process is completely autonomous, it takes place very quickly. The operator’s task is to monitor how the machine is operating and troubleshoot any problems. In addition, another task is to set the necessary extruder parameters.
The best machines in Russia produce on average at least 200 kg of finished products per hour. And an ordinary plant producing plastic products in Russia can produce 1000 meters of pipes. After making the blanks, they are cooled in special cooling baths, so they keep their shape perfectly. After all stages of the process, all necessary markings are applied to polypropylene pipes, then after packaging they are sent to the warehouse.
Equipment used
Each type of pipe requires its own production line. But basically all lines consist of different units, here is a list of machines and devices used in Russian enterprises of this type:
- Dispensers of different sizes for measuring and supplying raw materials;
- Extruder, which is the main means of production;
- Devices for pulling and sending products into the cooling system;
- Baths in the form of cooling systems;
- Machines for calibrating finished products;
- Device for cutting and measuring finished goods;
- Packers and labelers.
If you suddenly decide to open such a production in the Russian Federation, then you will need from 700 thousand to 2 million rubles to purchase the necessary equipment.
Raw materials
In Russia, manufacturers use different types of raw materials, depending on what kind of final product they want to receive in the end. Different materials have different performance properties, here are two main types of raw materials: propylene homopolymer is used to create sewer pipes and fittings. In the production of heating and plumbing systems, foreign raw materials are used - random propylene copolymer.

Kinds
- Block copolymer It is distinguished by the presence in the macromolecule of alternating homopolymer blocks, different in structure. Thus, a block copolymer of propylene and ethylene is a macromolecule in which monomer groups alternate: propylene and ethylene. Due to this, the polymer has additional properties - improved elasticity, increased resistance to thermal-oxidative aging, or an expanded range of permissible temperatures.
- Homopolymer A macromolecule that is homogeneous in its structure, in which identical monomer units are repeated, the most typical propylene polymer. It has basic properties that can be modified by adding additives and additives to the composition.
- Random (static) copolymer An irregular copolymer in which the monomer units are distributed randomly. Therefore, it is called statistical, since its structure contains 60% propylene monomers and 40% ethylene monomers, but in macromolecules the order of these units can be anything. It is characterized by a high degree of crystallization, and as a result, strength.
Let's consider the advantages of polypropylene products
This type of product has gained great popularity for a reason; there are many reasons why they are often purchased. This is primarily due to the positive properties that this product has, here is a list of them:
- Plastic products have very high strength;
- The material does not have the property of rusting or rotting;
- Able to withstand very large temperature changes;
- Do not affect the quality and taste of water;
- Plastic can be used for a very long time;
- Much lighter weight compared to metal materials.
In addition, thanks to simple manufacturing methods, polypropylene pipes and fittings are much cheaper than those made from other materials.
Basic properties
The raw material of polypropylene is propylene, obtained by cracking petroleum. After processing and polymerization, the substance acquires a number of valuable properties that ensure it is in wide demand. PP is highly resistant to substances: it tolerates acidic and alkaline environments well, and does not dissolve in organic compounds at room temperature. It does not absorb moisture and is not destroyed by water, and is a reliable insulator for electricity.
Granulated polypropylene can be painted or unpainted (mostly white). Organic dyes are used to impart color to primary plastic granules. Copolymers are also in demand - compounds of polypropylene with ethylene, with increased resistance to low temperatures and enhanced beneficial qualities. The copolymer has high impact resistance and is easy to process.
How to choose polypropylene pipes
Structure.
All polypropylene pipes can be divided into three types.
- Single-layer pipes
are made of pure polypropylene; such pipes are best suited for installing cold water supply. - Fiberglass reinforcement
increases the strength of the walls; this type of product copes well with high pressure and temperature (up to 90°C). They are used to install heating systems for private houses. - Reinforcement with foil
allows you to reduce the thermal expansion of pipes, so such products can withstand liquid heating up to +95°C. Their scope of application is the widest.
Installation
. When choosing polypropylene pipes, it is important to know about the nuances of their connection. Joints are welded using special soldering irons, and turns and branches are made by installing fittings. Pipes reinforced with aluminum foil are considered the most difficult to install. Experts recommend removing the metallized layer to the welding depth.
How not to buy counterfeit goods.
There are many counterfeit products on the Russian market, so a potential buyer should know several selection criteria. They will help reduce the risk of buying counterfeit products.
- The first thing you should do is take a photo or remember exactly what the brand logo looks like. You should pay attention to the size of the letters, font, color, number of capital letters. Very often, unscrupulous businessmen make basic mistakes by redrawing the trademark of a well-known manufacturer.
- On the official website you need to study the range of products. Knowing the location of the markings and the color of polypropylene, you can easily identify counterfeit goods.
- Sample pipes should be carefully inspected before purchasing. They must have the same thickness and a close to ideal circular cross-section. The presence of depressions, sagging and other signs of poor-quality casting is not allowed.
We have selected the 11 best manufacturers of polypropylene pipes for the rating. The products of these brands are widely represented in the Russian retail chain. When compiling the rating, the opinion of experts and reviews of domestic consumers were taken into account.
Where is it used?
Polymer materials have created a new generation of technology and played an important role in economic development. Primary polypropylene granules are actively used in production, replacing many expensive analogues and achieving a more efficient production cycle. Material used:
- In mechanical engineering. The high wear resistance and affordable price of polypropylene made it possible to use it for the manufacture of household appliances and cars.
- In medicine, the ability of polypropylene to withstand high temperatures is in demand, which has opened up opportunities for its sterilization. Syringes, inhalers and other equipment are made from polymer.
- In electrical engineering, the material acts as an insulator, and in this area it already competes with polyethylene. It is used in the production of lamp sockets, insulation shells, and the casings of televisions and other electrical appliances are made from it.
- The most important role is packaging. The material is called the “king of polymers” because it is non-toxic, flexible and easy to weld. Polypropylene films will soon seriously displace polyethylene on the market. The material is gaining ground in the manufacture of plastic bottles, containers and other packaging.
The most important factor ensuring the widespread use of polypropylenes is low cost, which makes it possible to reduce the cost of production industries. The material is increasingly used in the production of engineering plastics, because the field of electronics and high technology is in dire need of solutions that can make the product available for purchase. Polypropylene fibers are actively replacing fabrics, this is especially noticeable in the medical field.
Dynamics of growth in polypropylene production
The basic scope of application of polypropylene is the production of pipes used in industry and public utilities.
Thanks to this sector, global production of polypropylene quadrupled between 1990 and 2013, which is twice as high as the production of steel, aluminum, tin, paper and glass, which increased by a maximum of two times. From 2000 to 2013, Russia increased the annual mass of polypropylene produced by 3.5 times - from 243.8 to 848.6 thousand tons, which brought the material to a leading position in development among analogues.
The reason for the explosive growth was the advantages of PP over other materials on the same basis (PVC, polystyrene): it is environmentally friendly, since the manufacturing and disposal process does not harm the environment. Due to its reduced toxicity, legislation is favorable to its manufacturers.
