GOST 34233.12-2017 PDF

Full title and description

GOST 34233.12-2017 — "Vessels and apparatus. Norms and methods of strength calculation. Requirements for representation of the strength calculations carried out on the computer" (Russian: "Сосуды и аппараты. Нормы и методы расчета на прочность. Требования к форме представления расчетов на прочность, выполняемых на ЭВМ"). The standard specifies requirements for the content, formatting and forms of presentation for strength calculations performed using computers in the design and verification of pressure vessels and apparatus.

Abstract

This part of the GOST 34233 series sets out mandatory and recommended rules for how computer-based strength (stress/structural) calculations should be documented and presented. It covers the structure of calculation reports, required input and output data, identification of assumptions and boundary conditions, and additional requirements when numerical and special methods (for example, finite-element analyses) are used. The document is intended to ensure traceability, reproducibility and clarity of engineering calculations for vessels and apparatus used in chemical, petrochemical, oil‑refining and related industries.

General information

• Status: Active / introduced as an interstate (GOST) standard and adopted as a national standard of the Russian Federation (replacing the earlier national standard).
• Publication date: Approved July–December 2017; put into effect as a national standard on 1 August 2018.
• Publisher: Adopted/registered by the Federal Agency on Technical Regulation and Metrology (Rosstandart) and published commercially by standards publishers (e.g., Standartinform / commercial distributors).
• ICS / categories: Equipment for the chemical industry; petroleum and related technologies — commonly classified under ICS groups used for the GOST 34233 series (for example 71.120 and 75.200 for related parts of the series).
• Edition / version: Edition 2017 (GOST 34233.12-2017).
• Number of pages: Short technical publication — published editions list about 8–10 pages depending on publisher/format.

Scope

Applies to strength calculations performed on computers for vessels and apparatus covered by GOST 34233.1 through GOST 34233.11. The standard establishes minimum requirements for the content and format of calculation reports, required descriptive and numerical data, references to normative documents and material properties, statement of assumptions and boundary conditions, and special provisions for presentation of results obtained by numerical and specialized methods (e.g., finite element analysis). Use is described for equipment in chemical, petrochemical, oil‑refining and related industries, although its presentation rules may be applied to other strength calculations for vessel elements under relevant normative documents.

Key topics and requirements

• Structure and minimum content of computer-generated strength calculation reports (identification, purpose, input data, calculation steps, results and conclusions).
• Required specification of geometry, material properties, loads, boundary conditions and load combinations used in the computation.
• Documentation of calculation methods and algorithms, including references to applicable parts of the GOST 34233 series and relevant normative documents.
• Additional presentation and verification requirements for numerical and special methods (mesh description, convergence criteria, model validation, representation of results and post‑processing outputs).
• Traceability and reproducibility: requirement to supply source data files, input decks or solver settings where appropriate, plus clear statement of assumptions and simplifications.

Typical use and users

Used by mechanical, pressure‑vessel and piping engineers, structural analysts, design organizations, licensors and verification bodies preparing or reviewing strength calculations for pressure vessels, heat exchangers and related apparatus. Typical organizations include engineering design institutes, EPC contractors, equipment manufacturers in chemical, petrochemical and oil & gas industries, inspection and certification bodies, and technical authorities responsible for regulatory compliance.

Related standards

Main companion documents are other parts of the GOST 34233 series (GOST 34233.1 through GOST 34233.11) which provide the calculation norms and methods for specific vessel elements and conditions; related technical standards for welded steel vessels and general technical requirements (for example GOST 34347‑2017) are also commonly used alongside this part. International standards such as ISO 16528 (boilers and pressure vessels — performance requirements and procedures) were taken into account during development.
