锅炉和压力容器.第1部分:性能要求

[中文适用范围]： ISO 16528 的这一部分定义了锅炉和压力容器建造的性能要求。 ISO 16528 这一部分的目的不是解决锅炉和压力容器的操作、维护和在役检查。 关于压力容器承压部件的几何形状，ISO 16528本部分的范围包括以下内容： a) 焊接连接第一环向接头的焊接端部连接； b) 用于螺纹连接的第一个螺纹接头； c) 用于螺栓、法兰连接的第一个法兰面； d) 用于专有连接或配件的第一密封表面； e) 必要时的安全附件。 关于锅炉承压部件的几何形状，ISO 16528 本部分的范围涵盖以下内容： f) 给水入口（包括入口阀）到蒸汽出口（包括出口阀），包括所有互连可能面临过热风险且无法与主系统隔离的管道； g) 相关安全附件； h) 与服务中涉及的锅炉的连接，例如排水、通风、减温等。 ISO 16528的本部分不适用于核部件、铁路和船用锅炉、气瓶或管道系统或机械设备，例如涡轮机和机械肠衣。 [外文原描述]： ISO 16528-1:2007 defines the performance requirements for the construction of boilers and pressure vessels. It is not the intent of ISO 16528-1:2007 to address operation, maintenance and in-service inspection of boilers and pressure vessels. In relation to the geometry of the pressure-containing parts for pressure vessels, ISO 16528-1:2007 includes welding end connection for the first circumferential joint for welded connections, first threaded joint for screwed connections, face of the first flange for bolted, flanged connections, first sealing surface for proprietary connections or fittings and safety accessories, where necessary. In relation to the geometry of pressure-containing parts for boilers, ISO 16528-1:2007 covers feedwater inlet (including the inlet valve) to steam outlet (including the outlet valve), including all inter-connecting tubing that can be exposed to a risk of overheating and cannot be isolated from the main system, associated safety accessories and connections to the boilers involved in services such as draining, venting, desuperheating, etc. ISO 16528-1:2007 does not apply for nuclear components, railway and marine boilers, gas cylinders or piping systems or mechanical equipment, e.g. turbine and machinery casings.
