Eco Friendly Polyiso Pipe Insulation ,HDPIR Polyisocyanurate Foam Material Pipe Shell for nuclear power

In recent years, due to the increasing demand for liquefied natural gas (LNG) and liquefied petroleum gas (LPG), ultra-low temperature industry has also developed significantly. With this development, there has been a huge market for pipe supports and hangers made of non-metallic materials (compressed hardwood and high-density polyurethane foam).


HDPIR and GRE have designed and developed fixed or suspended low-temperature supports and hangers with different thermal and mechanical properties.
