石油、石化和天然气工业.炼油厂加热管厚度的计算

[中文适用范围]： 本文件规定了用于计算石油、石化和天然气行业新管及相关部件配件所需壁厚的程序和设计标准的要求。 这些程序适用于设计用于腐蚀性和非腐蚀性应用的管道。 这些程序是专门为炼油厂和相关工艺燃烧加热器管（外壳内的直燃吸热管）的设计而开发的。 这些程序不适用于外部管道的设计。 本文件没有给出有关管报废厚度的建议。 描述了估计加热器管剩余寿命的技术。 本文件是 API 530 第 7 版 (2015) 的补充，包括附录 1 和附录 2，其要求除本文件中指定的例外情况外均适用。 [外文原描述]： This document specifies the requirements for the procedures and design criteria used for calculating the required wall thickness of new tubes and associated component fittings for petroleum, petrochemical and natural gas industries. These procedures are appropriate for designing tubes for service in both corrosive and non-corrosive applications. These procedures have been developed specifically for the design of refinery and related process-fired heater tubes (direct-fired, heat-absorbing tubes within enclosures). These procedures are not intended to be used for the design of external piping. This document does not give recommendations for tube retirement thickness. A technique for estimating the life remaining for a heater tube is described This document is a supplement to API 530, 7th edition (2015) including addendum 1 and addendum 2, the requirements of which are applicable with the exceptions specified in this document.
