Insulation foam is now considered most effective, as this material has the lowest coefficient of thermal conductivity and also has excellent waterproofing properties. The latter characteristic is due to the presence in the composition of the material is 99 percent closed pores. Insulation foam neutral to chemicals, alkaline environments and acidic compounds. It belongs to the Flammability class G2 and has a high resistance to external influences.

General description

Rigid polyurethane foam has excellent heat insulation with low thickness. Thanks to these properties it is suitable for professional insulation of the tasks for economic and technical reasons, assume optimal energy savings. Water absorption of the material does not exceed 1.2-2.1% of the total volume. Insulation is flame retardant, even in direct fire.

insulation foam

Polyurethane foam Insulation has a negligible weight, which varies up to 60 kilograms per cubic meter. He is characterized by excellent durability and corrosion protection of metal structures. During installation there is no need to use additional fixing elements, in the process, no formation of cold bridges. Be isolated with this material you can design any shape and size.

Durability

Insulation foam is durability, due to the fact that the material does not rot and is not allowed under the influence of seasonal fluctuations in humidity and temperature. Not to mention the high environmental impact, therefore, on the hygiene standards material can be used in a cold technique that's meant to store food products.

foam insulation shell

Insulation is produced using polyurethane foam pouring in a form, which cannot form units called shells. They are used for the installation of pipelines, fabrication of sandwich panels and plates. Polyurethane foam can be sprayed on any materials on the type of metal, wood, brick, glass, and concrete. The configuration of the surface is irrelevant.

The Production of pipes with insulation of polyurethane foam

Insulation foam, the production of which will be described below, used in the manufacture of pipes, requiring special protection. The result is heat and water insulated product, which is manufactured according to GOST 30732-2006. As thermal insulation material in this case used polyurethane foam, while moisture protection is ensured by a plastic layer. These pipes are intended for construction of heating mains, the installation of which is underground. In the process of production of such three-layer systems uses high quality steel, which will be implemented by the transportation carrier.

foam insulation price

The Products are protected by foam layer, which eliminates heat loss. Steel and polyurethane foam are protected from exposure to groundwater that is provided by the presence of a special case, which is made of polyethylene. Steel pipes in foam insulation can be of two types, each of which involves the use of thick insulation layers. The first type is used for mounting in the Central regions, which differ in a temperate climate. The second type is designed for operation in conditions of extremely low temperatures, as for the Northern regions. Insulation foam (shell) in the production process is supplied with an ODK system that allows early detection of damage arising in the course of operation. It allows you to control the humidity of the insulation layer signaling at higher levels.

Prices for PPU

steel pipe in foam insulation

Polyurethane foam insulation, which is presented below, may be the only solution, if necessary, insulation of pipes. Thus, if you need more system, then the pipe diameter of 507 mm, wall thickness of 3.5 mm and a shell diameter of 125 mm, the price of insulation without steel pipe per meter will be 376 rubles. If you increase the above settings until 89х3,5х160 mm price increases to 552 roubles. Impressive dimensions equal to 630х8х800, suggest the value of 8600 rubles.

The Positive side of tubes in PPU-isolation

foam insulation manufacture

If you decide to insulate pipe by applying polyurethane, you can count on high-tech characteristics of the material. Among them are the low coefficient of thermal conductivity, which is 0.027 W/MK. Not to mention the durability and resistance to corrosion. Polyurethane will protect the steel pipe is better than armopanelt or the bitumen. The steel surface is not required to apply anti-corrosion coating that will ensure the safety of the more impressive heat than insulation made from mineral wool. After carrying out similar works pipe will be able to serve for 25 years or more. This is several times greater than the period which is given to the pipes without the appropriate processing. In the presence ofsystem ODK you will have the opportunity to control the integrity of the product during operation, excluding earthworks. It is necessary to highlight the economic benefits that are expressed in the fact that the use of pipes with polyurethane foam insulation reduces the time of installation work of heating networks in three times, lowers maintenance costs 9 times, but with regard to repairs, they will be cheaper in 3 times.

Conclusion

If used in advance of the insulated pipes described above, it is possible to significantly reduce the costs of construction and subsequent operation. You will have the opportunity to minimize the loss of degrees of heat, which, in use of such pipes is 2%. Products in PPU-isolation can be operated at high temperature ranges that range from -80 to +130 degrees, which is very suitable for difficult conditions in some regions of Russia.
