GOST 34233.1-2017 PDF

Full title and description

GOST 34233.1-2017 — "Vessels and apparatus. Norms and methods of strength calculation. General requirements". The standard sets general requirements, definitions and basic rules for strength and stability calculations of pressure vessels and process apparatus made of carbon and alloy steels, Fe–Ni alloys and non‑ferrous metals used in chemical, petrochemical, oil‑refining and related industries.

Abstract

This part (Part 1) of the GOST 34233 series establishes the general principles, supplied symbols and basic calculation approaches used across the series for determining allowable stresses, safety and stability coefficients, weld strength coefficients and rules for combining loads for vessels and apparatus subjected to internal or external pressure, axial and transverse forces, bending moments and inertial loads. It is intended to be applied together with the companion parts of the GOST 34233 series that cover specific geometries and components.

Scope

Applies to strength and stability calculations of pressure vessels and apparatus operating under single or repeated static loads from internal excess pressure, vacuum or external pressure, axial and transverse forces, bending moments and inertial effects. The standard covers vessels and apparatus constructed from carbon and alloy steels, Fe–Ni based alloys and non‑ferrous metals (aluminum, copper, titanium and their alloys) used in chemical, petrochemical, oil‑refining and other industries. It sets basic coefficients of safety and stability, allowable stresses and weld strength coefficients and is intended to be used together with other parts of the GOST 34233 series that address specific component types and calculation details.

Key topics and requirements

• Definitions, notation and general calculation methodology for strength and stability assessments of vessels and apparatus.
• Principles for determining allowable stresses and safety factors for different materials (carbon/alloy steels, Fe–Ni alloys, aluminium, copper, titanium alloys).
• Rules for combining loads: internal/external pressure, axial/transverse forces, bending moments and inertial loads.
• Requirements for assessing welded joints (strength coefficients) and for application of partial safety factors.
• Basic stability (buckling) checks and coefficients of reserve strength for shells, heads and closures.
• Reference to companion parts that provide formulas and procedures for specific geometries (cylindrical and conical shells, heads, nozzles, supports, etc.).

Typical use and users

Engineers and designers of pressure vessels, heat exchangers and process apparatus in chemical, petrochemical, oil‑refining and related industries; technical specialists performing strength calculations and mechanical integrity assessments; regulatory and conformity bodies reviewing equipment design for compliance; standards librarians and technical authors who reference calculation rules. The standard is used at the design, verification and documentation stages of equipment lifecycle.
