While the HydroFoamer was originally developed to optimize the application of rigid, closed-cell polyurethane (PU) foam to GRP pipes in hydropower projects, its core concept is adaptable across a wide range of industrial contexts. The system is capable of applying any sprayable material—including specialized polymer coatings commonly used for corrosion protection of steel pipes in the oil and gas sector.
Each project and sector has distinct technical and regulatory requirements. This section outlines the key parameters that define the system’s flexibility and performance.
The HydroFoamer applies a continuous, high-adhesion layer of material—most commonly PU foam—across both straight and curved pipe sections. In hydropower applications, this creates a structural bond that effectively locks pipe segments together across joints, reducing or eliminating the need for traditional restraining systems such as flanges, couplings, or welds.
The system supports a broad range of pipe types and dimensions, with an optimal focus on composite and polymer pipes such as GRP/FRP and HDPE. Standard working diameters range from 300 mm to 2000 mm, with pressure compatibility up to 40 BAR. These boundaries are set by the reach of the robotic crane system and the engineering limits of unrestrained joint systems, such as those used in high-pressure penstocks.
