1 总则1.1 本规定适用于化工装置仪表及管线采用蒸汽伴热和绝热方式的保温设计.1.2 仪表及管线保温的目的,在于保证仪表以及检测、调节系统的正常工作,减少测量附加误差。因此,在预期的环境温度下,仪表及管线内的介质,应满足下述要求:1.2.1 不应产生冻结、冷凝、结晶、析出等现象;1.2.2 保证仪表处于技术条件所允许的工作温度范围之内。
1 General Provisions 1.1 This Regulation applies to the thermal insulation design of chemical plant meters and pipelines adopting steam heat tracing and adiabatic methods.1.2 The purpose of heat preservation of meters and pipelines is to ensure the normal operation of instruments and testing and regulating systems and to reduce additional errors in measurement. Therefore, under the expected ambient temperature, the medium in the instrument and pipeline should meet the following requirements: 1.2.1 There should be no phenomenon of freezing, condensation, crystallization, precipitation, etc .; 1.2.2 Ensure that the instrument is working under the technical conditions Within the temperature range.
