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.
