"Isopex", pipe for heating and hot water supply: characteristics, types and reviews

Networks of external pipelines are increasingly equipped with modern technologies that offer the use of Isopex products. The pipe from this manufacturer is a complex version with one or several pipes inside. These designs can have different pipe diameters.

The products provide an outer shell, a heat insulation layer and a bearing pressure pipe. In the manufacture of such pipes, modified polyethylene is used. On sale you can find flexible pipes "Isopex", which are used for cold water supply, in this case PE-Xa is used in the production process.

Main types of Isopex pipe

On sale it is possible to meet the Isopex pipe in several varieties, among them:

• "Isopex-1".
• "Isopex-2".
• Isopex-4.

If we are talking about the first of the above brands, it should be noted that the product consists of an insulated pipeline, inside which there is one pipe. Such products are used in the housing and communal sector and during construction, as well as in the installation of underground systems. The pipes have a diameter that varies from 20 to 110 mm, and a liquid with a temperature of up to 95 ° C can move inside.

The highest pressure is 6 bar. During operation, short-term transportation of liquids with a temperature up to 110 ° C is possible. Such a pipe "Isopex" can be used at a higher pressure - 200 bar, while the wall has a maximum thickness of 15.1 mm.

Reviews about the pipe brand Isopex-2

This pipeline is pre-insulated, and inside it has two pipes. The products have been specially designed for heating and hot water supply systems, as well as moving other liquids. A feed tube is used, while a second pipe is needed to return the coolant.

The insulating layer acts as an insulator and further separates, guaranteeing, according to consumers, reliable heating. Pressure pipes have the same diameter, which can reach 50 mm. Consumers emphasize that the highest possible pressure is 6 bar, which is suitable for operation in almost any system. If there is a need to use pipes at a pressure of 200 bar, then you should buy those that have walls up to 6.9 mm thick.

Reviews about the Isopex-4 pipe

The Isopex-4 pipe is a system designed for the arrangement of flexible pipelines. Inside there are four pipes, which have the characteristics of self-compensation. According to buyers, the cost of this product is much higher than others, its design provides for the use of two pipes for heating and two more are used for hot water supply.

Diameter, according to consumers, is quite extensive and varies from 25 to 40 mm, working pressure is 6 bar. For hot water pipes have a diameter of 20 to 32 mm, and if you order products individually, the diameter can be selected by the customer.

Technical characteristics of the functional pipe

Isopex is a pipe that has certain technical characteristics. Among them, one should distinguish the peroxide method of error, which consumers are often interested in. This product is ready for service for about 50 years, but this parameter will be met under the appropriate operating conditions.

The pipe is not sensitive to low pressure losses, aggressive water and resistant to chemicals. Isopex is a pipe with a thermal conductivity of 0.38 W / mK, with regard to the tensile strength, the test in this case was carried out at a temperature of 20 ° C, this parameter in this case is 26-30 N / mm ² . With an increase in temperature to 80 ° C, the tensile strength becomes smaller - 18-20 N / mm2.

The modulus of elasticity reaches 400 N / mm ² , while the coefficient of linear expansion at 100 ° C is 2.0-10E-41 / K. Crystallite begins to melt at a temperature range of 130 to 136 ° C.

Reviews about the Isopex pipes

Isopex is a pipe that has become quite popular today because of its advantages. Among others, consumers note environmental friendliness, as well as low exposure to corrosion and most aggressive environments. Buyers note that these pipes can be used for a wide range of temperatures, the limit of which is 95 ° C. The product can withstand a brief temperature rise up to +110 ° C.

As the buyers emphasize, when water supply is sufficiently low friction, in addition, the pipe withstands an impressive water delivery rate, while there are minor hydraulic losses. The insulated pipes "Isopex" are quite easy to cut and join during installation. Due to the fact that the structures have an anti-oxygen barrier, the products do not pass oxygen, which ensures the durability of the heating system.

Thanks to the properties, the pipes can become part of the cold and hot water systems, and also they can be used for transportation of chemical liquids. As the buyers assure, butt joints in the track are minimal. This ensures the reliability of the system. For the laying of such pipes there is no need to equip deep trenches, it will be narrow enough, which distinguishes Isopex from steel products.

The price of pipes from the manufacturer Isopex

The pipe "Isopex", the price of which can vary depending on the variety, found its wide distribution today. Before choosing it is necessary to understand the basic characteristics of products. Among other things, you should highlight the dimensions. If they are equal to 2x20 - 2110, then the product will have to pay 1235 rubles. With the increase in sizes up to 2х25 - 2,3110 the pipe will cost 1450 rubles. If you have a tube with the marking 2х32 - 2,9125, then the cost will be slightly higher and amount to 1690 rubles., Whereas for the product 2x40 - 3,7140 the consumer will have to pay 1920 rubles.

In addition to the characteristics of functional pipes, it is worth familiar with the features inherent in thermal insulation. For example, its density is 57 kg / m ³ , while the thermal conductivity at 50 ° C will be 0.033 W / mK. The number of closed cells exceeds 90%, but the diffusion resistance varies from 40 to 80 μ.
