Сети наружных трубопроводов все чаще are 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.
Products provide an outer shell,insulating layer and bearing pressure pipeline. In the manufacture of such pipes, modified polyethylene is used. On sale it is possible to meet flexible pipes "Isopex", which are used for laying cold water supply, in this case PE-Xa polyethylene is used in the process of production.
On sale it is possible to meet the Isopex pipe in several varieties, among them:
If we are talking about the first of these brands, thenit 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. 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.
Наивысшее давление - 6 бар.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.
This pipeline is pre-insulated,but 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 andfurther 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.
The Isopex-4 pipe is a system,intended 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 extensiveand varies from 25 to 40 mm, the 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.
«Изопэкс» – труба, которая обладает определенными 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 lossespressure, aggressive water and resistant to chemicals. Isopex is a pipe whose thermal conductivity is 0.38 W / mK, as for 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 / mm2. With an increase in temperature to 80 ° C, the tensile strength becomes smaller - 18-20 N / mm2.
The modulus of elasticity reaches 400 N / mm2, 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.
«Изопэкс» – труба, которая стала сегодня is quite popular 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, with water supplythere is a sufficiently low friction, in addition, the pipe can withstand 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.
Due to the properties, pipes can become part ofcold and hot water systems, as well as they can be used to transport chemical liquids. How to assure buyers, butt connections in the track are minimal. This ensures the reliability of the system. There is no need to equip deep trenches for laying such pipes, narrow ones will be enough, which distinguishes Isopex from steel products.
Pipe "Izopeks", the price of which may varydepending on the variety, it has found its wide distribution today. Before choosing, you need to deal with the main characteristics of the products. Among others it is necessary to allocate the sizes. If they are equal to 2x20 - 2110, then the product will have to pay 1235 rubles. With an increase in size to 2x25 - 2.3110 the pipe will cost 1,450 rubles. If you have a pipe with a marking 2x32 - 2,9125, then the cost will be slightly higher and will be 1690 rubles, while the consumer 2x40 - 3,7140 will have to pay 1920 rubles.
In addition to the characteristics of functional pipes, you should familiarize yourself with the features peculiar to thermal insulation. For example, its density is 57 kg / m3while the thermal conductivity at 50 ° C will be 0.033 W / mK. The number of closed cells exceeds 90%, while the diffusion resistance varies from 40 to 80 μ.
