GOST 34233.8-2017 PDF

Full title and description

GOST 34233.8-2017 — "Vessels and apparatus. Norms and methods of strength calculation. Jacketed vessels and apparatus" (Russian: «Сосуды и аппараты. Нормы и методы расчёта на прочность. Сосуды и аппараты с рубашками»). The standard establishes rules and calculation methods for the strength assessment and structural design of vessels and apparatus fitted with jackets (double-walled constructions, heating/cooling jackets and similar assemblies) used in chemical, petrochemical and related industries.

Abstract

This standard defines loads and load combinations, allowable stresses, methods for determining membrane and bending stresses, requirements for jacket geometry and attachment, considerations for thermal and pressure-induced stresses, corrosion allowances, welds and joints, support and mounting arrangements, and documentation requirements for strength calculations of jacketed vessels. It is intended to be applied together with other parts of the GOST 34233 series covering general rules and specific vessel types.

Scope

GOST 34233.8-2017 specifies norms and methods for strength calculations of vessels and apparatus that incorporate jackets (single or multiple jackets, annular jackets, or other double-wall arrangements). It covers internal and external pressure loads, self-weight and contents, thermal loads and differential expansion between shell and jacket, wind and seismic influences where applicable, and load combinations relevant to safe operation. The standard is to be used alongside the common parts of the GOST 34233 series that provide general provisions and calculation procedures for shells, heads, nozzles and supports.

Key topics and requirements

• Definition of jacket types and typical geometric configurations used for heating, cooling and secondary containment.
• Load identification and combination rules (internal/external pressure, weight, thermal strains, wind, seismic and accidental loads).
• Calculation methods for membrane and bending stresses in shell and jacket walls; treatment of local stress concentrators (nozzles, attachments, welds).
• Requirements for allowable stresses, material selection, corrosion allowances and temperature-dependent properties.
• Rules for assessing differential thermal expansion between shell and jacket and related restraint stresses.
• Guidance on attachments, weld joint design, stiffening elements and openings in jackets.
• Support, mounting and stability considerations for jacketed assemblies.
• Documentation and presentation requirements for strength calculation reports (reference to companion parts of the series for computational formats).

Typical use and users

Primary users are mechanical and pressure-vessel design engineers, process and petrochemical equipment designers, plant engineering companies, inspection and certification bodies, and technical specialists responsible for mechanical integrity and safety of industrial vessels. The standard is used during design, verification, modification and fitness-for-service assessments of jacketed vessels in chemical, oil & gas and related industries.

Related standards

GOST 34233.8-2017 is part of the multipart GOST 34233 series ("Vessels and apparatus. Norms and methods of strength calculation") and is intended to be used together with other parts (for example, general rules and methods for shells, heads, nozzles, heat-exchangers, column-type apparatus, and presentation of calculation results). It replaced or superseded earlier national documents in this subject area (for example, GOST 25867-83 was withdrawn when the series was introduced).
