Foam glass is a very good thermal insulation product, which was once mainly used for building exterior walls. Now, as people are familiar with this material, they find that it can be processed into a pipe shell, which can be used in heat supply pipeline insulation and equipment low-temperature pipeline. Its role is to protect the pipeline from weathering by thermal insulation.

The thickness of general pipe foam glass is determined by referring to the formula in the relevant design manual, and the minimum insulation thickness of heating and heating pipes in the Design Standards for Energy Efficiency of Civil Buildings can also be referred to for reference. The role of foam glass shell is to reduce the heat loss of heat medium during transportation, save energy, and improve the economy and safety of system operation. The function of insulation layer is to reduce energy loss, save energy, improve economic efficiency, ensure the operating parameters of the medium, and meet the production and living requirements of users.

The thickness of the insulation layer of the pipe shell can be determined based on the thermal calculation of the insulation of the heating pipeline. The thicker the determined insulation layer, the smaller the heat loss of the pipeline, and the more fuel-efficient it is; However, with the increase of thickness, the cost of thermal insulation structure increases, and the investment cost increases. The foam glass pipe shell can be applied to high temperature, low temperature, air, underground, dry and wet pipelines. The selected insulation material for the pipe shell should be able to adapt to these conditions. When selecting insulation materials, the thermal performance should be considered first, and then the construction conditions should be taken into account. These are all the functions of selecting pipe shells.
