GB/T 16508.1-2022Shell boilers - Part 1: General requirements (English PDF)

1 Scope

GB/T 16508.1-2022 is the Chinese national standard on shell boilers - part 1: general requirements, in the field of energy and heat transfer engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 9 March 2022 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 October 2022. Classification: ICS 27.060.30, CCS J98. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

1.1 This document specifies the general technical requirements for shell boiler range, boiler rated parameters, design and calculation, manufacturing and inspection, installation and operation, performance test, energy saving and environmental protection.

1.2 This document applies to the following range of stationary shell boilers.
