GB/T 36669.1-2018In-service pressure vessel inspection—Part 1: Hydrogenation reactor (English PDF)

Foreword

GB/T 36669 "Inspection of Pressure Vessels in Use" is divided into the following four parts.

---Part 1. Hydrogenation reactor;

--- Part 2. Multi-layer dressing container;

--- Part 3. Coke tower;

--- Part 4. Oxygen chamber.

This part is the first part of GB/T 36669.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

1 Scope

This part of GB/T 36669 specifies the items and methods for periodic inspections using hot wall hydrogenation reactors.

This section applies to the main material is 14Cr1MoR (or other 1.25Cr-0.5Mo steel), 12Cr2Mo1R (or other 2.25Cr-1Mo) Chromium-molybdenum steel such as steel), 12Cr2Mo1VR (or other 2.25Cr-1Mo-0.25V steel), and internal hot-wall hydrogenation with electrode overlay coating The reactor is inspected periodically. For equipment having similar process conditions, materials, and structural forms to the hydrogenation reactor, reference may be made to this section.

This section does not apply to periodic inspections using cold wall hydrogenation reactors.
