Polyurethane foam insulation for district heating and subsea flowlines
PU foam insulation systems provide thermal protection for district heating and cooling pipelines, subsea flowlines, and industrial process piping. High-density polyurethane foam is applied between the steel carrier pipe and an outer HDPE casing, achieving thermal conductivity as low as 0.025 W/mK.
Complete PU insulation plants include pipe cleaning, preheating, foam injection, HDPE jacketing, and end-seal stations. The system ensures exceptional thermal efficiency with minimal heat loss, making it ideal for long-distance district heating networks and deepwater applications.
Pipe capacity ranges from 2" to 48" diameter, with fully automated production capabilities and precision foam density control. All systems are designed for 30+ year service life with environmentally friendly foaming agents.
