Scope

Rules for this Code Section have been developed considering the needs for applications that include piping and heat transfer components for refrigerants and secondary coolants. This Code prescribes requirements for the materials, design, fabrication, assembly, erection, test, and inspection of refrigerant, heat transfer components, and secondary coolant piping for temperatures as low as −320°F (−196°C), whether erected on the premises or factory assembled, except as specifically excluded in the following paragraphs. 本规范部分的规则已考虑到包括制冷剂和二次冷却剂的管道和传热组件在内的应用需求。 本规范规定了温度低至 −320°F （−196°C） 的制冷剂、传热部件和二次冷却剂管道的材料、设计、制造、组装、安装、测试和检查的要求，无论是在场所内安装还是在工厂组装，除非以下段落明确排除。
