External piping networks are increasingly being equipped with modern technologies that offer the use of Isopex products. The pipe from this manufacturer is a complete design with one or more pipes inside. These designs may have different pipe diameters.
Products include an outer shell, an insulating 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 laying cold water supply, in this case, PE-Xa grade polyethylene is used in the production process.
The main varieties of the pipe "Isopex"
On sale you can find pipes of the Isopex brand in several varieties, among them:
- "Isopex-1".
- Isopex-2.
- Isopex-4.
If we are talking about the first of the mentioned brands, it should be noted that the product consists of an insulated pipeline, inside of which one pipe is located. Such products are used in the housing and utilities sector and during construction, as well as in the construction of underground systems. Pipes have a diameter that varies from 20 to 110 mm, and fluid 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 temperatures up to 110 ° C is possible. Such an Isopex pipe can also be used at a higher pressure of 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 has two pipes. Products have been specifically designed for heating and domestic hot water, as well as the movement of other liquids. The kit uses a supply pipe, while a second pipe is needed to return the coolant.
The insulation 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 purchase those that have walls up to 6.9 mm thick.
Reviews on the pipe "Isopex-4"
The pipe "Isopex-4" is a system designed for the arrangement of flexible pipelines. Four pipes are located inside, which have the characteristics of self-compensation. According to customers, 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.
The diameter, according to consumers, is quite extensive and varies from 25 to 40 mm, while 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 consumer.
Functional pipe specifications
"Isopex" is a pipe that has certain technical characteristics. Among them, the peroxide error method, which consumers are often interested in, should be highlighted. It is ready to serve such a product for about 50 years, but this parameter will be met under appropriate operating conditions.
The pipe is not sensitive to low pressure losses, aggressive water and resistant to chemicals. “Isopex” is a pipe whose thermal conductivity is 0.38 W / mK, with regard to 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 increasing temperature to 80 ° C, the tensile strength becomes less - 18-20 N / mm 2 .
The modulus of elasticity reaches 400 N / mm 2 , while the coefficient of linear expansion at 100 ° C is 2.0-10E-41 / K. The crystallite begins to melt at a temperature range from 130 to 136 ° C.
Reviews on pipes "Isopex"
Isopex is a pipe that has become quite popular today due to its advantages. Among others, consumers note environmental friendliness, as well as low susceptibility to corrosion and most aggressive environments. Buyers note that these pipes can be used at a wide temperature range, the limit of which is 95 ° C. The product can withstand a short-term increase in temperature to +110 ° C.
As buyers emphasize, during water supply there is a fairly low friction, in addition, the pipe withstands an impressive water supply rate, while minor hydraulic losses are noted. Heat-insulated pipes "Isopex" is quite easy to cut and connect during installation. Due to the fact that the structures have an anti-oxygen barrier, the products do not pass oxygen, which guarantees the durability of the heating system.
Due to its properties, pipes can become part of cold and domestic hot water systems, and they can also be used to transport chemical liquids. As buyers assure, butt joints in the route are minimal. This ensures system reliability. For laying such pipes there is no need to equip deep trenches, narrow ones will be enough, which compares Isopex from steel products favorably.
The price of pipes from the manufacturer "Isopex"
The Isopex pipe, the price of which may vary depending on the variety, has found its wide distribution today. Before choosing, you need to understand the basic characteristics of the products. Among others, sizes should be highlighted. If they are equal 2x20 - 2110, then for the product you will have to pay 1235 rubles. With an increase in size to 2x25 - 2.3110 the pipe will cost 1450 rubles. If you have before you a pipe marked 2x32 - 2.9125, then the cost will be slightly higher and amount to 1690 rubles, whereas for a 2x40 product - 3.7140, the consumer will have to pay 1920 rubles.
In addition to the characteristics of functional pipes, it is worth familiarizing yourself 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 equal to 0.033 W / mK. The number of closed cells exceeds 90%, but the diffusion resistance varies from 40 to 80 μ.
