GOST 34233.2-2017 PDF

Full title and description

GOST 34233.2-2017 — "Vessels and apparatus. Norms and methods of strength calculation. Calculation of cylindrical and conical shells, convex and flat bottoms and covers". The standard establishes rules, calculation methods and formulae for the strength assessment and design of cylindrical and conical shells and of convex and flat dished ends and covers used in vessels and apparatus.

Abstract

This standard specifies norms and methods for strength calculation of cylindrical and conical shells, convex and flat bottoms and covers of pressure-containing vessels and apparatus used in chemical, petrochemical, oil‑refining and related industries. It covers calculations under internal overpressure, vacuum or external pressure and under axial, transverse and bending loads; it is intended for use when geometric deviations and manufacturing tolerances of the calculated elements do not exceed specified regulatory limits.

Scope

GOST 34233.2-2017 applies to the strength calculation of cylindrical and conical shells, convex and flat bottoms (dished ends) and covers of stationary vessels and apparatus operating under static loads caused by internal excess pressure, vacuum or external pressure and by axial/transverse forces and bending moments. The methods are applicable provided manufacturing and geometric deviations of the calculated elements do not exceed limits prescribed by regulatory documents. The standard is intended for design, verification and manufacturing support of pressure-containing elements in chemical, petrochemical, oil and gas and related industries.

Key topics and requirements

• Formulas and analytical methods for stress and strength calculation of cylindrical and conical shells and of convex and flat bottoms and covers.
• Design procedures for assessing membrane, bending and combined stresses under internal/external pressure and applied mechanical loads.
• Rules for determining required thicknesses, reinforcement of openings and local stiffening where applicable.
• Limits of applicability related to geometric deviations and manufacturing tolerances.
• Required material and allowable stress considerations, safety factors and referenced test/inspection practices.
• Normative references and alignment with relevant international standards (for example, ISO 16528 series considered in the development).

Typical use and users

Used by pressure‑vessel and process equipment design engineers, mechanical and structural engineers, manufacturers of vessel heads and shells, inspection and certification bodies, technical regulators, and maintenance/fitness‑for‑service engineers. Typical applications include design and verification of storage tanks, process vessels, heat exchanger shells, and other pressure‑containing components in chemical, petrochemical, oil & gas and related industries.
