Steel pipes in polyurethane foam insulation have firmly taken a leading position in the construction market. This is due to the fact that the lines demonstrate trouble-free operation throughout the entire service life. Polyurethane foam, which is used to create an insulating layer, is resistant to temperature extremes, mechanical stress, and aggressive environments. Spraying polyurethane foam allows you to make the temperature loss of the transported medium to a minimum, which is especially important when designing communal routes in regions with a harsh climate.

Russian plants of polyurethane foam pipes offer a wide range of products, complete order in a short time. Making a direct application will allow you to receive an order on time by the selected delivery method.


Steel pipe in factory pre-insulated

A pipe in polyurethane foam insulation is a monolithic structure that looks like a „pipe in a pipe" in section:



Steel pipe. The carrier pipe through which the working medium is transported.



A layer of polyurethane foam. It is applied by spraying, the layer thickness varies according to the customer’s requirements.



Protective shell. Made of dense polyethylene or galvanized steel.



The result is a dense structure that can not only deliver, but also protect what will be inside the assembled system. Polyurethane foam has good shock-absorbing qualities, is able to protect against mechanical damage, which is important when laying heating mains near railways, tramways, highways.

The choice of the type of protective layer depends on the location of the pipeline installation: pipes in a polyethylene protective sheath are used for channelless underground laying, galvanized protection is selected for above-ground laying of the pipeline.


Advantages of PPU pipes

Shorter pipeline assembly times and a long service life are not the only advantages of steel pipes that are produced in our country. PPU steel pipes are:



Wide range of applications. Products are purchased for surface and underground laying, for bringing all types of communications to residential complexes, social facilities, medical institutions, and sports facilities. Steel pipes manufactured in accordance with GOST 30732-2020 are used for the installation of oil and gas pipelines.



Ease of assembly. The small weight of the pipe, the factory equipment with fittings according to the project allows to reduce the installation time.



Low heat transfer coefficient minimizes heat loss during hot water transportation. Good thermal insulation is especially important in regions with high temperature fluctuations.



Plants celebrate trouble-free operation throughout the entire period – 30 years. At the request of the customer, the elements are completed with SODK (operational remote control system). This makes it possible to determine the location of the breakdown, to eliminate the defect in a short time.



Pipes in a dense factory shell do not require the use of concrete wells, boxes when installed underground, which also reduces the cost of installation and shortens the time of work.



The use of pre-insulated pipes and fittings in polyurethane foam insulation will take the building object to a new level. By placing an order for products directly from the manufacturer, you can shorten the waiting time for delivery. The pipeline, assembled from pipes in factory insulation, will ensure the transportation of gaseous and liquid media to the client with minimal temperature loss, protection from aggressive media, damage.


Saving the budget when using polyurethane foam pipes does not consist of the cost of the material of manufacture and the reduction in the cost of the process of assembling a monolithic pipe. Costs are reduced at the stage of installation and operation of the line. The price of a pipe in polyurethane foam insulation depends on:



GOST and steel grades of the supporting steel pipe;



Wall thickness and diameter of the steel pipe;



Shell type;



Insulation type.



Domestic manufacturers offer a wide range of products: polyurethane foam pipes and related fittings in insulation. Upon completion of production, all products undergo strict control of compliance with established standards and GOST. Based on the results, each batch receives a certificate of conformity and a quality certificate.
