GB/T 8175-2008

This standard provides design guidelines for thermal insulation of industrial equipment and pipes, specifying calculation methods for insulation thickness, material selection, and structural design to minimize heat loss or gain. It is applied in energy-intensive industries such as petrochemical, power generation, and heating systems, where efficient thermal management is critical for reducing energy consumption and ensuring process safety. The guide is used by engineers during the design phase of new installations or retrofitting of existing piping and equipment insulation systems.
