GOST 34233.9-2017 PDF

Full title and description

GOST 34233.9-2017 — "Vessels and apparatus. Norms and methods of strength calculation. Apparatus of column type" (Russian: «Сосуды и аппараты. Нормы и методы расчета на прочность. Аппараты колонного типа»). The standard establishes rules and calculation methods for strength, stability and allowable stresses for column-type vessels and apparatus supported on cylindrical or conical supports under combinations of internal or external pressure, self-weight and contents, wind and seismic moments, eccentric weight loads, temperature-restraint loads and other external actions.

Abstract

This document specifies norms and methods for strength calculation of column-type apparatus used in chemical, oil & gas and related industries. It covers load combinations, determination of stresses in shell and supports, criteria for stability and references requirements for foundation bolts and concrete in its informative Appendix A. It is intended to be used together with other parts of the GOST 34233 series and related standards.

General information

• Status: Active / Introduced for the first time (implemented as a national/interstate standard).
• Publication date: Approved 14 December 2017; Date of introduction: 1 August 2018.
• Publisher: Approved by the Federal Agency for Technical Regulation and Metrology (Rosstandart) as a interstate (GOST) standard; developed under intergovernmental technical committees and industry developers.
• ICS / categories: 71.120; 75.200 (industry classifications for vessels/apparatus and oil/gas & chemical equipment).
• Edition / version: 2017 (GOST 34233.9-2017; first introduction of this part).
• Number of pages: reported between 22 and 25 pages depending on publisher/extract (commonly listed as 24–25 pages in commercial catalogues; some registries list 22 pages).

Scope

The standard applies to column-type apparatus (columns, packed or tray towers and similar vertical vessels) that rest on cylindrical or conical supports and operate under internal excess pressure or external pressure, their own weight and contents, and external loadings such as wind, seismic actions, eccentric loads, and stresses arising from restrained thermal deformations. It provides calculation procedures for stress evaluation, support-shell interaction, stability assessment and rules for combining loads for strength verification. The standard is intended to be used together with other parts of the GOST 34233 series and related national standards.

Key topics and requirements

• Definitions and classification of column-type apparatus and their supports.
• Load cases and recommended combinations (internal/external pressure, self-weight, contents, wind, seismic, eccentric loads, thermal restraint loads).
• Methods for calculation of shell and support stresses and strain distributions.
• Criteria and procedures for stability and buckling checks of supports and shell sections.
• Rules for interaction between support shell (supporting skirt) and vessel wall; calculation of local stresses at support junctions.
• Requirements and recommended allowable stresses for foundation bolts and concrete (informative Appendix A).
• Cross-references to other parts of the GOST 34233 series for complementary methods and presentation of calculations.

Typical use and users

Primary users are mechanical and pressure-vessel engineers, structural designers, petrochemical and refinery equipment designers, fabrication and inspection organizations, certification bodies and regulatory authorities. The standard is used during design, strength assessment, modification and assessment of column-type apparatus to ensure compliance with industry-accepted strength and stability practices.

Related standards

This part is one element of the GOST 34233 series (see in particular ГОСТ 34233.1–34233.12) and is intended to be applied together with related national standards such as ГОСТ 34283 and ГОСТ 34347. It was prepared taking into account/alongside international documents (references in catalogues show links to ISO 16528 series as related material).

FAQ

Q: What is this standard?

A: GOST 34233.9-2017 is the interstate (GOST) standard that specifies norms and methods for strength calculation of column-type vessels and apparatus (vertical columns and towers) used in chemical and oil & gas industries.

Q: What does it cover?

A: It covers load definitions and combinations (pressure, weight, wind, seismic, eccentric and thermal restraint loads), calculation methods for stresses in shell and supports, stability/buckling checks, and guidance on foundation bolt and concrete allowable stresses (Appendix A). It is applied together with other parts of the GOST 34233 series.

Q: Who typically uses it?

A: Mechanical and structural engineers, designers of pressure vessels and towers, fabricators, inspection and certification bodies, and regulatory authorities in industries such as petrochemical, oil & gas and chemical processing.

Q: Is it current or superseded?

A: As published and approved on 14 December 2017 and introduced on 1 August 2018, the standard is listed as active in official registries and commercial catalogues. No general superseding revision was identified in the consulted registries; users should verify the latest status with the national standards body or an up-to-date registry before relying on it for compliance decisions.

Q: Is it part of a series?

A: Yes — it is one part of the multi-part series ГОСТ 34233 (parts 1–12), which together provide comprehensive rules and presentation requirements for strength calculations of vessels and apparatus.
