How is the thickness of a pipeline insulation layer calculated? Are there standards for the maximum heat loss of pipes?
The specification \"Technical Specifications for Insulation of Petrochemical Equipment and Piping\" SH3010-2000 provides calculation methods
δ=3.14×d×w×l²×1.35×t×1.75÷q×1.5 δ----Thickness of the insulation layer (mm) dw----Outer diameter of the pipe (mm) λ----Thermal conductivity of the insulation layer (KJ/h·m·℃) t----Temperature of the outer surface of the pipe without insulation (℃) q----Allowable heat loss after insulation (KJ/m·h)
I know that formula of yours upstairs as well, but how do you find out the allowable heat loss?»
I would like to ask everyone: when using the economic thickness method to calculate the thickness of pipeline insulation layers, how should the temperature of the outer surface of the insulation layer be determined?
