GOST 34233.7-2017 PDF

Full title and description

GOST 34233.7-2017 — "Vessels and apparatus. Norms and methods of strength calculation. Heat-exchangers" (ГОСТ 34233.7-2017, Сосуды и аппараты. Нормы и методы расчета на прочность. Теплообменные аппараты). The standard sets norms and calculation methods for strength assessment of shell-and-tube heat exchangers and air coolers used in chemical, petrochemical, oil‑refining and related industries under internal pressure, vacuum or external pressure.

Abstract

GOST 34233.7-2017 establishes requirements and calculation procedures for the structural elements of shell‑and‑tube heat exchangers and air‑cooling apparatuses to ensure strength under single and repeated loads. It is intended to be used together with the general part of the series (GOST 34233.1) and other parts of the GOST 34233 series that cover shells, bottoms, and fatigue/low‑cycle requirements. The standard was prepared based on the prior national standard GOST R 52857.7–2007 and replaces that document.

Scope

The standard applies to shell‑and‑tube heat exchangers and outdoor/air cooler type heat‑exchange apparatuses used in chemical, petrochemical, oil refining and similar industries. It covers strength‑calculation methods for structural elements when operating under internal overpressure, vacuum or external pressure and under single or multiple loading conditions, provided geometric deviations and manufacturing inaccuracies do not exceed tolerances set by normative documents. GOST 34233.7 is intended to be used with the general rules in GOST 34233.1 and other parts of the GOST 34233 series.

Key topics and requirements

• Strength calculation procedures for shell‑and‑tube heat‑exchanger elements and air coolers under various loading scenarios (internal pressure, vacuum, external pressure).
• Limits of applicability tied to geometric deviations and manufacturing tolerances (calculations apply when deviations do not exceed normative tolerances).
• Reference to general requirements and other parts of the series (use in conjunction with GOST 34233.1 and related parts covering shells, bottoms, lids, and fatigue calculations).
• Design formulas, safety factors and conditions for single and multiple loading cycles relevant to process industry equipment.
• Cross‑references to technical requirements for specific equipment (for example, GOST 31842‑2012 for petroleum industry shell‑and‑tube heat exchangers).

Typical use and users

Primary users include mechanical and pressure‑vessel design engineers, heat‑exchanger manufacturers, petrochemical and oil‑refining plant designers, inspection and certification bodies, and technical safety authorities. The standard is used during design calculations, verification of existing equipment, and preparation of technical documentation for pressure equipment in the covered industries.

Related standards
