GOST 34233.10-2017 PDF

Full title and description

GOST 34233.10-2017 — Vessels and apparatus. Norms and methods of strength calculation. Vessels and apparatus operating with hydrogen sulphide (H₂S) media. The standard establishes strength-calculation rules and special requirements for carbon and low-alloy steel pressure vessels and apparatus that operate under internal pressure in corrosive, H₂S-containing wet environments.

Abstract

This standard sets requirements and calculation methods for the strength of welded vessels and apparatus exposed to static and repeated static loads under internal excess pressure in sour (H₂S-containing) wet corrosive environments. It addresses material selection, allowable service conditions, and measures to prevent sulphide-related cracking (for example use of H₂S-resistant materials and inhibitors). The document is intended to be used together with the general parts of the GOST 34233 series.

General information

• Status: Active (in force as a national/interstate standard).
• Publication date: Introduced by Rosstandart order 14 December 2017; put into effect 1 August 2018.
• Publisher: Interstate standard adopted for use in the Russian Federation (implemented by the Federal Agency on Technical Regulating and Metrology / Rosstandart).
• ICS / categories: Chemical and petroleum equipment; typical classifications include OKС/ICS codes related to chemical technology and oil & gas equipment (examples: 71.120; 75.200).
• Edition / version: Edition 2017 (standard number GOST 34233.10-2017; replaced the previous national standard GOST R 52857.10-2007).
• Number of pages: 12 pages (typical published text length).

Scope

Applies to design-strength calculations for pressure-containing parts of vessels and apparatus made of carbon and low-alloy steels that operate under internal excess pressure at temperatures up to about 200 °C in corrosive, H₂S-containing wet environments. The standard covers static and repeated-static loading regimes and defines limits and calculation approaches intended to prevent sulphide stress cracking and related degradation mechanisms. It is to be used together with the other parts of the GOST 34233 series and replaces earlier national documents on the same topic.

Key topics and requirements

• Methods and formulas for strength calculation of shells, heads and other pressure-containing parts for vessels and apparatus in H₂S service.
• Material suitability criteria for carbon and low-alloy steels exposed to H₂S-containing wet environments, including measures to mitigate sulphide stress cracking (selection of resistant grades, hardness limits, use of inhibitors, heat treatment and welding controls).
• Service-condition thresholds and indicators relevant to sour-service risk (examples in related guidance: partial pressure thresholds and dissolved-H₂S concentrations that influence cracking risk are discussed in accompanying normative commentary).
• Compatibility and application notes aligning this GOST text with international norms for boilers and pressure vessels (the standard takes into account provisions of ISO 16528 parts).
• Documentation and computational-reporting requirements for strength calculations (used together with the GOST 34233 series parts covering presentation of calculations and computational methods).

Typical use and users

Primary users are pressure-vessel designers and structural/mechanical engineers in oil & gas, petrochemical, and chemical industries; manufacturers and fabricators of welded pressure vessels; inspection and certification bodies; asset integrity, corrosion and materials engineers responsible for sour-service equipment. Regulators and procurement specialists consult the standard when specifying equipment for H₂S-containing services.

Related standards

GOST 34233.10-2017 is part of the wider GOST 34233 series (strength-calculation methods for vessels and apparatus). It was prepared on the basis of the earlier national document GOST R 52857.10-2007 (now withdrawn) and takes into account international standards ISO 16528-1:2007 and ISO 16528-2:2007. For materials-selection and sour-service cracking guidance practitioners commonly also consult ISO 15156 / NACE MR0175 and other industry documents addressing H₂S resistance.
