Do white iron pipes need insulation?

   

White iron pipelines require insulation under specific conditions, and the specific analysis is as follows:

1、 Scenarios requiring insulation

Transportation of high or low temperature media

High temperature scenario: If the temperature of the medium transported by the pipeline exceeds 50 ℃, insulation is required to reduce heat loss and energy consumption.

Low temperature scenario: If the temperature of the medium is lower than the dew point temperature of the environment (such as cold air, chilled water), insulation can prevent the formation of condensed water and prevent pipeline corrosion or freezing. For example, frozen water pipelines are prone to condensation in humid environments, and insulation layers can prevent water vapor from penetrating.

Antifreeze requirement

In cold regions or winter, uninsulated pipelines may rupture due to the freezing of the medium.

Burn prevention and personnel safety

If the surface temperature of the pipeline exceeds 60 ℃ and requires frequent maintenance or personnel contact, insulation is necessary to prevent burns. For example, the steam pipes in the boiler room need to be equipped with anti scald insulation layers.

Process requirements

Some process flows require stable medium temperature, and insulation can maintain temperature fluctuations within an allowable range
