Note. According to the direction of heat flow, it can be divided into thermal insulation and cold insulation. 3.2 Economic thickness The calculated thickness of the insulation layer is when the sum of the annual heat dissipation (cold) loss cost after insulation and the annual amortized cost of insulation investment is the minimum.4 General requirements4.1 Equipment, pipelines and their accessories with any of the following working conditions should be insulated. The outer surface temperature is higher than 323 K (50 ℃) and the heat loss needs to be reduced; a) In process production, it is necessary to reduce the temperature of the medium or delay the condensation of the medium; b) Equipment, pipelines and accessories that do not require insulation during process production, but whose outer surface temperature exceeds 333 K (60 °C) and cannot be used Other measures to prevent burns. c) ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 4272-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 4272-2024_English as soon as possible, and keep you informed of the progress.
