Valtec fiberglass reinforced pipes

Currently, polyethylene pipes are becoming more common and are slowly beginning to replace pipes made of cast iron and steel.
The main reason for this is the high technical parameters of polyethylene material. Valtec polyethylene pipes from the Italian manufacturer fully meet these requirements. There is a huge variety of manufacturers of these pipes and it is very difficult for ordinary people to cope with the choice, because their appearance is basically the same, but the manufacturing technology and characteristic qualities are different for everyone.

Perhaps the main criteria for choosing polyethylene pipes, like any other product, are good quality indicators and an affordable price.

General characteristics

High technical parameters and a wide range of applications are the main reasons for replacing steel and cast iron analogues with PP fiber Valtec pipes reinforced with glass fiber.

For their manufacture, high-strength plastic PPR 100 is used, between 2 layers of which a fiberglass propylene layer is placed.

This type of risers is the best option for arranging pipelines for supplying hot and cold water, heating structures, and air conditioning systems.

The main feature of the highway elements made from these products is the optimal ratio of plastic layers and fiberglass reinforcement. Thanks to this, the products become more durable and rigid compared to conventional plastic counterparts.

In addition, such elements of pipeline systems have low thermal expansion.

Thanks to the use of high-tech, universal modifications of polypropylene, the products are resistant to low and high temperatures and can withstand high pressure.

The production process is strictly controlled, which eliminates the slightest deviation from linear parameters or technological errors.

Valtek assortment

Valtek's product range includes the following polypropylene products:

• PPR PN 20: Intended for cold and hot water no more than seventy degrees Celsius and pressure up to ten bar. Produced without reinforcement. The operating pressure is twenty bar. Diameter size from twenty to ninety millimeters. • PP-FIBER PN 20: For temperatures up to ninety degrees and operating pressures up to six bar.

Valtek is the holder of third place in the ranking of companies producing polypropylene pipes. The quality of the products produced by this company is in no way inferior to the first places, but the prices of this manufacturer are adequate, which cannot but please domestic consumers.

Where are Valtec pipe products used and how long do they last?

The production of a well-known company fills the plumbing market with high-quality engineering and plumbing products.

Today, it is difficult to imagine the functioning of drinking water supply systems, heating systems, sewerage and ventilation structures without Valtec PP pipes. In the production of elements for these systems, the best materials are used and the latest technologies are applied.

The company offers solid polypropylene pipes for cold water supply lines.

Valtec glass fiber reinforced PP pipe with an outer diameter of 20 mm to 90 mm is very effective in arranging heating and hot water supply. By the way, the range of Valtec polypropylene pipes is quite wide and complies with GOST.

If operating rules are observed, pipe engineering structures can function for up to 50 years. In addition, the warranty on all Valtec products is 7 years , which is very important for all consumers.

Installation

Considering that PPs do not bend, it will be necessary to purchase connecting fittings. The product is cut to size, taking into account all angles and turns of the pipeline. To join two sections together, the ends are heated using a soldering iron and then connected with a fitting.

Fiberglass-reinforced pipes are first stripped at the ends to remove any metal layer from where it will go into the fitting. This prevents delamination of the walls.

Main important characteristics:

• Produced in diameters from twenty to sixty-three millimeters. • PP pipelines are usually sold in four meter lengths. It is the optimal value for transportation and installation, but if the need arises, these sections are connected. • The permissible operating pressure at temperatures up to twenty-five degrees Celsius corresponds to 25 bar, at 79 degrees -10 bar. Note: According to GOST, the strength standard is 50N/10mm.

How to choose a quality product?

Among the variety of products on the modern construction market, it is important to choose high-quality products. To do this, you need to familiarize yourself with the technical documentation, when reading which you need to pay attention to:

manufacturing company;
main technical characteristics;
production technology.

When choosing pipes, like any other product, you need to remember that the main criteria should be an adequate price and high quality of products.

Valtec glass fiber reinforced polypropylene pipe corresponds to exactly this reasonable ratio.

Therefore, we will talk about the properties, advantages, and disadvantages of these pipeline parts in more detail.

Advantages

All products have advantages and disadvantages. Valtec fiberglass-reinforced polypropylene pipes are no exception. Among the many positive properties, the most significant include:

long service life. Let us repeat, you can use RR risers for five decades , provided that the operating rules are not violated (correct selection of temperature, pressure, and other parameters);
complete immunity to corrosive effects. To put it simply, polypropylene and glass can neither rust nor rot;
increased resistance to chemically active substances. Thanks to this property, the parts have found application in various fields of industry, as well as in everyday life;
ideal smoothness of the inner surface, which ensures absolutely complete passage of the working environment. This factor ensures minimal accumulation of deposits inside the riser, which cannot be said about metal analogues;
environmental Safety. Among all plastics, polypropylene is one of the few environmentally friendly materials. Taking this into account, PPR pipes are used to supply drinking water, since during the contact of the risers with the liquid, no changes in its chemical composition occur;
light weight, which ensures easy transportation and installation of structures made of PPR pipes with glass fiber reinforcement;
multifunctionality. This means that the products function equally well in different systems: heating, sewer, water supply (hot and cold supply), ventilation, “warm” floors.

Valtec polypropylene pipes. general information

Manufacturer rating

Valtec is a leading supplier of polymer products for heating systems on the Russian market.

Technical characteristics of PP pipes

Since its founding, Valtek has gained a significant place in the global market. Its specification is large plumbing devices for water supply, heating and wastewater networks. In 2010 they started producing PP pipes.

There are single-layer and multi-layer PP pipelines.

Aluminum is used to reinforce multilayer pipes. Thanks to the reinforcement, complete protection against air penetration is ensured, thereby reducing the risk of corrosive formations in the internal system of heating devices.

For the production of PP pipes, very durable polypropylene class PPR-100 is used. Such products are used in heating and plumbing systems and in industrial enterprises. They are capable of operating at temperatures up to +90C. The company produces products in accordance with GOST. Thanks to the use of a modified type 3 PP-R polymer, the products are significantly resistant to temperature fluctuations and network pressure.

These pipes are durable, their service life reaches fifty years. Valtek provides a 7-year warranty period for its products.

The assortment includes solid products used for cold water supply and low-temperature systems. Installation is carried out by resistance welding using connecting elements (fittings) special for pipes produced by Valtek, because the quality of any system can only be achieved by matching all elements.

At each production stage of polypropylene pipes there is strict control and the slightest defects and deviations from the standard are not acceptable.

Valtec PP pipes are marketed in special four-meter tubes. On which all technical characteristics are indicated.

Advantages and disadvantages of Valtek pipelines

pros

The numerous advantages of polypropylene products include:

• As stated above, these pipes are durable; • Resistance to aggressive environments and chemicals, corrosion; • Polypropylene is resistant to fungal growths, mold, and ultraviolet radiation; • Smoothness of the internal walls, which prevents the formation of various types of deposits; • Polypropylene is an environmentally friendly material, does not change the properties of water, which makes it an ideal option for installing drinking water supply; • Light weight, which is a big advantage during transportation and installation; • Multifunctional use.

Minuses

One of the disadvantages of polypropylene material is the presence of a large coefficient of thermal expansion.

So if the permissible temperature value is exceeded even by one degree, the pipes begin to increase in length.

In addition, the melting point of polypropylene is 140-170C, so they cannot be used in systems with high temperatures.

Although today this problem is solved by reinforcement. To avoid deformation changes, the design of polypropylene products is reinforced with a frame, which imparts rigidity and prevents the pipe from bending.

Flaws

Like all pipe products, polypropylene risers have some disadvantages. Or rather, problems begin in the event of a violation of the installation work on the construction of the highway.

The following points can be highlighted:

adhere to the requirements set out in the technical documentation in terms of the maximum permissible temperatures and pressures for which the products are designed;
Before installation, it is necessary to familiarize yourself in detail with the documents for the product, since there are still unscrupulous manufacturers whose products want to be of a higher quality. Although, if you look at the appearance, the risers look quite good.

Advantages and disadvantages of Valtec pipes

Of course, the essence of polypropylene pipes can be most fully revealed by their advantages and disadvantages, which are discussed below using the example of Valtec products. So, the numerous list of advantages of polypropylene pipes includes:

Durability . As mentioned earlier, their service life is 50 years with the correct selection of temperature and pressure in the system;
Immunity to corrosive processes;
Resistance to the influence of aggressive environments and various chemical assets, which allows them to be used for production and industrial purposes;
Smooth inner surface, which does not create conditions for the growth of various deposits, which is typical for metal pipes;
Environmentally friendly. Polypropylene is an environmentally friendly material that is ideal for transporting drinking water, since its physical and chemical properties do not change upon contact with this material;
The lightness of the material facilitates easy transportation , and the installation of polypropylene pipes makes it much easier;
Multifunctionality is associated with the possibility of using polypropylene pipes not only for water supply and sewer systems, but also for all types of heating , including radiator wiring and “warm floor” systems;
Thanks to the reinforcement with an aluminum layer in a continuous manner and in the central part of the pipe, the problem of oxygen supply is solved and installation work is simplified when connecting to press fittings.

It is quite difficult to find any flaws in polypropylene pipes, since all possible problems, as a rule, arise when technology is not followed during installation. In general, all the disadvantages of using polypropylene pipes can be reduced to the following points:

the need to process polypropylene pipes of some modifications with a trimmer , which complicates the installation process;
mandatory compliance with the maximum permissible temperature and pressure specified in the technical documentation;
As a precaution, you should carefully study all the documents for the purchased product so as not to fall for the bait of unscrupulous manufacturers, since the appearance does not allow you to draw any conclusions about the quality of the product.

How are Valtec pipes connected?

When connecting polypropylene pipes or changing the direction of a main line, fittings are used. Like risers, these parts are made from special grades of polypropylene. The range of connecting elements is simply huge.

The low price of these parts is another undoubted advantage of lines made of Valtec polypropylene pipes.

Important! All components, including fittings, must be Valtec branded. When using parts from other manufacturers, there is no guarantee that the connections will be tight.

To join parts, use a soldering iron (welding machine). When purchasing it, you should pay attention to the completeness of the device. That is, in addition to the soldering device itself, the kit should include certain attachments, a list of which is provided in the technical documentation.

Heating time and other parameters are indicated in the instructions for the welding mechanism.

Valtec's place in the ranking of pipe manufacturers

Of course, Valtec is far from the only manufacturer of polypropylene pipes that deserves due attention. Today, many large enterprises, both foreign and domestic, produce polypropylene pipes using their own technology and using various modifications of the material. Based on media data, you can make a short rating of companies and see what place Valtec occupies in it:

Polypropylene pipes made in Germany are rightfully considered to be the highest quality and most durable, in particular from the company Banninger Reiskirchen , which uses the new generation of polypropylene PP-RCT and Wefatherm, which works with polypropylene PP-R. The pipes are available in white and more often in green, and the production warranty is 10 years. But, due to the significant cost, the pipes of these companies are not very popular in our country, although their quality deserves respect;
Polypropylene pipes from the Czech company WAWIN Ecoplastik are known all over the world, since this brand was one of the first to produce this type of engineering plumbing. The quality of the product is beyond doubt, but the price makes you think about other possible options;
In third place of honor is the previously discussed Italian company Valtec , whose product quality is comparable to the previous manufacturer, but the cost will please the domestic consumer;
Polypropylene pipes made in Turkey, namely from companies such as TEBO, Pilsa, Vesbo and many others, have a lower cost and, accordingly, are somewhat inferior in quality to previous companies;
The most budget-friendly options are Chinese (BLUE OCEAN, Dyzain, etc.), as well as, sadly, domestic manufacturers such as Heisskraft, Polytek and RVK.

Based on the foregoing, we can conclude that Valtec is one of the most popular and sought-after companies in the plumbing market. The high quality of raw materials, high-tech production, a well-thought-out installation system and, of course, the reasonable price of polypropylene pipes take them to a leading position in this market segment.

Operating rules

If you want the system to function efficiently for decades, you need to adhere to basic operating rules.

The operation of pipes is permitted in the mode specified in the technical passport.
The use of PP-Fiber reinforced structures is prohibited:

at temperatures above +95⁰С;
at a pressure higher than permissible for the specified operating classes;
in buildings of A, B, C categories (according to fire safety rules);
in rooms where the heat source is heated above +130⁰С;
in rooms with elevator units in the heating system;
in expansion, safety, overflow, signal structures, as well as separate fire-fighting pipeline systems.

Compliance with the rules of installation and operation will allow you to forget about repairs of pipeline systems for a long time, which is the dream of every owner.
