Thermally insulated pipes with foamed polyurethane in a PE shell (PPU): Efficiency, Durability, Quality
Pipes with thermal insulation made of polyurethane foam (PPU) are a modern solution for heating mains, hot water supply and industrial engineering systems. Due to the unique properties of the material, they guarantee minimal heat loss, durability and ease of installation. This type of pipe is used exclusively for underground laying.
Technical characteristics of steel heat-insulated PPU pipes:
- Pipe diameter: from 32 to 426 mm.
- The thermal conductivity coefficient of polyurethane foam: 0.027–0.033 W/(m·K) is one of the lowest among thermal insulation materials.
- Operating temperature: up to +140°C (short-term up to +150°C).
- Maximum working pressure: depends on the type of conductor pipe (up to 2.5 MPa for steel pipes).
- Protective casing: Polyethylene (PE) – for laying in the ground or in open conditions without contact with ultraviolet light.
- Insulation layer thickness: varies depending on the pipe diameter and technical requirements (from 30 to 70 mm).
- Waterproofing: the protective coating of pipes and pipeline parts reliably prevents moisture from penetrating the thermal insulation layer, extending the service life and efficiency of thermal insulation throughout its entire service life.
Advantages of PPU pipes:
- Minimal heat loss: up to 40% more efficient compared to traditional materials.
- Long service life: up to 30–50 years, depending on operating conditions.
- Anti-corrosion protection: the conductive steel pipe is not exposed to moisture and aggressive environments.
- Possibility of laying systems with signal cables: monitoring the integrity of the pipeline in real time.
- Ease of installation: the presence of shaped elements (bends, tees, compensators) simplifies the installation of systems.
- Ductless installation possible: thanks to the strong, corrosion-resistant polyethylene jacket and rigid polyurethane, our pre-insulated pipes can be laid in the ground without the need for additional concrete trays.
Application of heat-insulated PPU pipes:
- Main and local heating mains.
- Central heating systems.
- Hot and cold water supply.
- Transportation of liquid and gaseous media in industrial facilities.
- Refrigeration systems.
Thermal insulation for PPR (polypropylene) pipes: An effective solution for modern engineering systems
In addition to steel pipes with PPU insulation, an important element of energy-efficient engineering systems is the insulation of polypropylene pipes (PPR). This type of pipe is widely used for transporting cold and hot water, as well as in heating systems.
Why choose our pipes?
We manufacture thermally insulated pipes according to the standards DSTU B V.2.5-31:2007 and EN 253 , which guarantees quality and compliance with modern energy efficiency requirements. We use advanced PPU pouring technologies to ensure a uniform layer of insulation.
Additional services:
- Calculation of the optimal insulation thickness depending on the parameters of your system.
- Supply of shaped elements for any network configuration.
- Technical support and consulting at all stages of the project.
